Executive Summary
Pterra LLC (“Pterra”) was contracted by Transpower New Zealand, Ltd.
(“Transpower”) to conduct planning review studies to determine the need for
enhancing transmission capacity to the Christchurch area, specifically, with respect
to voltage stability, and to conduct the necessary dynamic simulations to confirm or
modify the plan for enhancement.
Pterra reviewed technical reports and documents performed and prepared by
Transpower, and confirmed the simulation results with Pterra’s own independent
simulations using the PSS/E software. Furthermore, Pterra performed dynamic
simulations related to voltage stability of the South Island Upgrade.
Considering the existing Transpower criteria, international practice and simulations
conducted of the South Island grid, planning criteria for voltage stability were
proposed for this study that included:
•
A MW margin, measured on the PV curve
•
Contingencies to test using dynamic simulations
•
Transient response criteria for the timeframe immediately following a
contingency up to a few seconds later
•
Post-transient response criteria that apply to the timeframe from 10 seconds
to minutes after a contingency
The databases used for this study were provided by Transpower. For the power flow
model, Pterra developed a detailed model based on the model case provided by
Transpower, with minor adjustments to match the 2007 system conditions.
Additional power flow cases were developed representing future years by increasing
load at constant power factor, taking into account non-scaleable load. For the
dynamic simulation model, Pterra reviewed the provided data and provided
additional models to represent complex load, contactor shedding, switched capacitors
and proposed static var compensators.
PV curve analyses indicate that the MW margins, which measure additional load that
can be supported within voltage stability criteria, for future Upper South Island (USI)
load are less than 100 MW for the existing system operating during winter wet
conditions. The most severe contingency with respect to voltage stability is the loss
of the Islington-Tekapo B 220 kV line. QV curve analyses confirm this finding.
The dynamic simulation assessment showed that load modeling had a significant
impact on the assessment for voltage stability of USI. Various load models were
studied and qualified in accordance with the level of risk that a model will provide
sufficient MW margin to support additional load in the USI. Two models are
proposed for conducting dynamic assessments voltage stability
•
A moderate risk model comprising of 19% motors with a 10% constant power
load component

•
The low risk (or conservative) model comprising of 38% motor with a 15%
constant power load component, with a provision for shedding of some
motors on contactor tripouts below 0.6 pu voltage
Limits on additional USI load supported by the existing system, as determined using
dynamic simulation, are similar or greater than those determined by PV and QV
curve methods. Hence, steady-state analyses for the cases studied provide a
conservative measure of voltage stability.
However, dynamic simulation assessment provided improved differentiation of
options to defer the need for a new 220 kV line. Of several options studied, the
following offered the best potential to support additional USI load, in order of
effectiveness:
•
Large SVC in combination with fixed capacitor banks at Islington. This
solution has the potential for supporting levels of USI load up to 2022. In
combination with series compensation, even higher levels of USI load may be
supported. However, certain technical issues beyond the scope of this study
need to be addressed.
•
Series compensation. Technically, this solution offers additional MW capacity
for up to 2014 in either the moderate or the low risk load model. Because of
this characteristic, the solution addresses a wide range of risk associated with
load response, and offers a robust option for mitigating the need for a new
220 kV line.
•
Capacitors and SVCs at Islington, Kikiwa and Ashburton. Incremental
additions at the three sites provide for USI load of up to 1475 for the
moderate risk model and 1375 for the low risk model are possible.
•
Extreme contingencies involving double circuit outages are no more severe
than the worst normal or design contingency (single line to ground fault with
delayed clearing). Hence stability countermeasures specified for normal
contingencies would also provide support for these types of extreme
contingencies. Extreme contingencies involving autoreclosure on a fault
event and a bus section outage with fault are more severe than the most
severe normal contingency. Hence, in order to mitigate these extreme
contingencies, solutions applied to normal contingencies need to be
augmented beyond 2015. For example, an additional +500 MVAR SVC at
Islington is needed to support USI load of up to 1800 MW under these
extreme contingencies.
As the available surplus transmission capacity decreases in the South Island, and
mitigating measures are implemented to defer the need for a new 220 kV line, it
would be of benefit to future system operators to provide increased capability for
observability and controllability of the power system. This would include an
expanded RPC at Islington and online dynamic security assessment.

Section 1. Introduction
Pterra LLC (“Pterra”) was contracted by Transpower New Zealand, Ltd.
(“Transpower”) to conduct planning review studies to determine the need for
enhancing transmission capacity to the Christchurch area, specifically, with respect
to voltage stability, and to conduct the necessary dynamic simulations to confirm or
modify the plan for enhancement.
1.1. Background
Transpower is planning to enhance the supply capacity to Christchurch and the
regions North of Christchurch in the South Island. By approximately 2010, the
transmission capacity to these regions will be constrained by the voltage stability
concerns even though some thermal capacity would still be available in the
transmission lines.
Transpower has completed the planning studies, assessing the need for a new
transmission investment as well as comparing the benefits of alternative
transmission options. The transmission capacity of the existing power system was
assessed using VQ and PV analysis. The studies indicated that the transmission
system is close to the practical transmission capacity with shunt reactive
compensation (at the receiving end).
The analysis results are sensitive to the planning assumptions, especially the
assumptions on modelling of the behaviour of the loads and on the prudent stability
margins to be maintained in operation. By varying the assumptions and using
different analysis techniques, it may be possible to show an increased capacity limit
is achievable through further shunt compensation and thus defer transmission
investments.
Transpower is planning to submit a grid upgrade proposal to the Electricity
Commission (the Electricity Regulator in New Zealand) by mid September 2007 and
requires this advice to support the ‘need date’ for further investment in the
transmission system.
1.2. Objectives
The objectives of Pterra’s work are to determine whether it is practicable and/or
desirable to extend the transmission capacity beyond that identified in the
Transpower report1 with respect to:
1
•
International practice and the extent of shunt compensation employed;
•
Operating the power system with the required shunt compensation;
•
Control systems and requirements; and
•
Any other relevant technical issues.

Pterra Consulting
Pterra is to review technical reports and documents already performed and prepared
by Transpower, and if necessary, confirm the simulation results. Furthermore, Pterra
is to perform dynamic simulations related to voltage stability of the South Island
Upgrade.
1.3. Scope of Services
To meet the objectives, Pterra conducted its Services in two parallel tasks.
In Task 1, Pterra reviewed the planning studies already carried out by Transpower.
This review included an assessment of the assumptions and analytical methods
applied by Transpower with respect to Good Industry Practice. From the preceding
review, Pterra assessed the appropriateness of conclusions made by Transpower for
planned investments and need dates. In particular, Pterra identified options for
deferring the investments using low cost shunt compensation. In the course of
conducting Task 1, Pterra carried out power flow studies and voltage stability
analysis to confirm various aspects of the transmission plan.
In Task 2, Pterra planned and implemented a dynamic study to assess voltage
stability of Transpower’s transmission plan. As with Task 1, a key objective of the
dynamic study was to defer major investments in favor of using lower cost shunt
compensation. Where such deferment was indicated, Pterra identified the critical
planning assumptions that allowed the deferment, the stability margins on which
such assumptions were based and the level of risks associated with such planning
assumptions. Pterra also developed comments on the operability of the shunt
compensated system with deferred investments, with specific reference to necessary
control systems, practicability, consistency with international practice and other
relevant aspects.

Section 2. Planning Criteria
Voltage stability is the focus of recent changes in planning criteria used by utilities
and regulatory agencies worldwide. The trend is away from the steady-state
methods of assessing stability to increased emphasis on dynamic response.
However, steady-state-methods and criteria based on these methods have not been
eliminated entirely and continue to be the initial method for screening voltage
stability response in power systems.
This section discusses, in the following order:
•
General principles of voltage stability related planning criteria,
•
Comments on the planning criteria currently applied by Transpower,
•
Planning Criteria applied by Transpower to a study of North Island
•
Proposed planning criteria for this study, based on dynamic response.
•
At the end of this section, we provide a list of references that supplement the
discussions and provide further background material for present use and
future development of planning criteria for Transpower.
2.1. Voltage Stability-related Planning Criteria
As the power system transitions from a normal operating state to an emergency
state following a contingency, the response of voltage throughout the system is
influenced by several factors that are modeled differently in steady-state and
dynamic simulation models. Among the aspects that are different are:
•
The transient response of rotating equipment provides for higher reactive
power available (over short durations) than is defined by the steady-state
reactive power capability.
•
Static VAR devices (SVD) such as thyristor-controlled reactors and switched
capacitor banks respond to different voltage conditions (typically lower than
normal) during transient conditions than what steady-state simulations
provide. The actual reactive power of SVDs would vary as a square of the
voltage at their terminals at the point in time of the dynamic simulation.
•
Load characteristics change during, after and in the extended time period
following a contingency in a significantly different way than may be simulated
in a steady-state “ZIP” model.
ZIP is a shorthand notation for a type of model of electrical loads. The model
specifies that load is represented by the formula:
Pv = Po * ( Z * V 2 + I * V 1 + P * V 0 )
Where Pv is the load at voltage V, Po is the nominal value of the load and Z, I
and P are constants whose sum equals 1.
•
Onload tap-changing transformers would respond tap-step by tap-step in
accordance with the control response characteristics of the transformers
rather than the assumed response in a power flow model.

•
Capacitors that switch in based on monitored conditions may do so within a
timeframe that impacts voltage stability. The voltage at which the switch in
occurs determines the actual MVARs delivered to the system. Multiple
capacitor banks would switch in sequence and this time delay also has an
impact on voltage stability.
Hence, voltage stability related planning criteria tend to specify the acceptable
transient response as defined by the power system controls and equipment, taking
into account the differences with steady-state modeling listed above. This transient
response may be divided into time regimes or defined by a nomogram.
Time regimes may be defined as:
1. Transient - takes place in the first few cycles to several seconds following the
initial disturbance. This would account for the “fast” phenomena such as
response of relays, voltage regulators, breaker action, SVDs, etc. This would
also account for some of the “slow” phenomena such as a capacitor
switching, load self-modifying response, tap-changing transformers,
generator excitation limiters, governors, etc.
2. Post-transient – takes place from about 10 seconds following the disturbance
to the minutes time frame when oscillations from the initial events of the
disturbance have died down and voltages are quiescent. The time regime
defines the post-contingency steady-state voltage determined through
dynamic simulation.
Example transient criteria are:
1. Step response – voltage recovery defined by meeting voltage level
checkpoints during the transient period. For example, a two step criteria2:
a. Voltages should recover to above 0.5 pu after 0.5 seconds following
clearing of a fault in a contingency
b. Voltages should recover to within 90% of the pre-contingency voltage
after 5 seconds.
2. Nomogram response – voltage recovery is qualified based on a voltage
nomogram that system voltages must remain above throughout the
transient. An example of this type of criteria is shown in Figure 2-1, based on
a proposed standard for low voltage ride-through of wind farms by FERC.

An example of post-transient criteria taken from the US WECC3 planning guidelines:
1. Voltage to rest within 95% of the pre-contingency value
2. Voltages are damped.
Load modeling is a critical aspect of determining voltage stability. The typical model
used for stability simulations, described as the ‘PIQZ’ model, where the real power
portion of the load varies as voltage (also referred to as “constant current or I”
characteristic) and the reactive portion of the load varies as the square of voltage
(also referred to as “constant impedance or Z” characteristic) is not preferred since it
ignores important characteristics of load response.
Two types of load modeling are seeing increasing use and application as part of
planning standards, as follows:
1. Complex load model - this model represents distinct portions of the load. A
typical breakdown includes: small motors, large motors, discharge lighting,
transformer saturation, constant power and PIQZ loads. The percentage of
each component is important to voltage stability and may be specified as part
of standards. For example, WSCC requires modeling of at least 20% motor
loads in planning studies4. The complex load also seeks to capture the effect
of step-down transformation and distribution feeder impedances.

From experience of Pterra’s investigators, this is the largest motor component requirement to represent
consumer air conditioning used as a planning standard. Saudi Arabia uses a larger motor component but
this includes large pumps that are not air conditioning load. The comparison is difficult to make with the

2. Self-restoring load – this model represents load on modifiers which attempt to
adjust the average demand of the load in response to changes in voltage at
the terminals. This model is used for equipment on thermostats and
consumer voltage controllers. The load may respond initially to a voltage
change in a PIQZ or motor characteristic, but through the action of the
controllers recover the demand level to the pre-contingency value. Over the
long-term (or in steady-state analysis), the load looks and behaves like
constant power, but during the transient period, the load may have two or
more distinct demand-voltage characteristics.
Load modeling is important to voltage stability and all efforts to obtain accurate
modeling improve the planning and supporting simulations. In order to ensure
consistent application, criteria may specify the load model to use for conducting
performance tests.
2.2. Comments on Planning Criteria applied by Transpower
The following discussion contains comments on the Planning Criteria as applied by
Transpower to the Planning Study.
1. Contingencies. A contingency analysis is a useful tool for screening
contingencies that are critical to voltage stability. This is also a necessary
tool whenever there is a change in system configuration. Although the critical
contingencies with respect to voltage stability are well-defined and recognized
in the Planning Studies, it would be useful to add a section describing the list
of potential contingencies and the results of contingency analysis. It would
also be useful to see similar discussion when the bussing and series
compensation options are presented.
There is a variance between the Planning Study and the Planning Criteria in
that in the former, transmission circuits on the same tower are treated
individually as n-1 events, and in the latter5, the loss of both circuits may be
treated as an n-1 event subject to likelihood of occurrence. International
practice shows both forms being used and it is typically a planning
determination based on probability, cost and other factors that establishes
which of the two forms is applied.
2. Loading of existing transformers. Transformers will typically have overload
capacity to support 120% loading on cyclical basis. We note that transformer
aging is affected by magnitude, frequency and duration of overloading events,
and criteria may be more specific about how long or how often the overload
conditions are allowed. This is not an issue that is central to the voltage
stability problem but may have an impact if the system model does not match
the planned reinforcement of transformation capacity and leads to false load
response.
primarily heating motors in the South Island load. The level of penetration is as high as 38% per a study
of the Auckland load (see Reference 3, Section 1.4).

3. 5% demand. Several utilities and operators in the US and worldwide use a
similar criteria, including the PJM6 Interconnection. We note that voltage
stability is also dependent on the power factor of load and the component mix
of load. As load components change with increasing demand, the margin
provided by the 5% demand assumption also changes.
4. Generator voltages. The setpoint for generator voltage regulators determines
the reserve that each generator would have to respond to voltage-related
events. Within the limits of acceptable plant operation, the setpoints may be
viewed as adjustable parameters in a planning study to optimize the
operations of the grid with respect to voltage stability.
5. Post contingency capacitor switching. The dynamic voltage recovery of the
grid to specific disturbances can vary. In stiff sections of the grid, the
dynamic response may be fast, and indeed capacitor switching would be
inadequate. If the characteristic response is slower, there may be sufficient
time for capacitor switching to help. From a steady-state assessment point of
view, the applied criteria has an inherent safety margin but may be overly
restrictive if the dynamic response provides for sufficient response time.
6. Critical nose point voltage at 0.98 p.u. The value is determined on a postcontingency basis as the point where the power flow solution no longer
solves. For operability and controllability concerns, monitoring the nose point
voltage is important. A high nosepoint voltage could mean that operators
may not have the warning of dropping voltages before a voltage collapse
event. Likewise, the high nosepoint voltage implies that the shape of the
nosecurve has been “flattened” by a large component of shunt static vars;
leading to a very high ∆V/∆P ratios, a state where voltages may be difficult to
control.
7. For planning purposes, we observe that utilities more typically determine the
nosepoint voltage pre-contingency or under normal, all-in conditions. This
relates to the limits of observability in that if the pre-contingency nosepoint is
high, operators will not have the benefit of dropping voltages as a warning of
incipient voltage collapse. In the case of the New York Independent System
Operator (‘NYISO’), the voltage limit is set based on the shape of the knee of
the nosecurve. (See Figure 2-2).

Critical Voltage based

of nose curve
Figure 2-2: Example nose curves for pre- and post-contingency conditions.
Because of differences in power flow solution methods and embedded
heuristics, the point on the nosepoint when the power flow no longer solves
may vary from one power flow software to another. Methods such as
eigenvalue analysis and continuation power flows have been applied to clearly
establish that the nosepoint indeed represents a singularity7 where such is in
question. However, in our opinion, these efforts to clarify the nosepoint are
mooted by the fact that the steady-state model of the power flow is an
approximation that requires confirmation using dynamic simulation, especially
where the nosecurve is based on response to a contingency.
8. Modeling of static var devices and synchronous condensers. Another means
of ensuring reactive reserve is to apply criteria wherein the pre-contingency
reactive output of these devices is near zero (‘floating’) or absorbing vars.
The amount of reserve would need to be determined from QV and PV curve
results or from dynamic simulations. The Planning Study indicates that
Transpower is already applying some form of this criteria, and it may useful
to state so explicitly in Section 5.2 of the Planning Study report.
9. Because of the interaction of time-dependent response from dynamic loads,
excitation systems and limiters, tap-changing under load and static var
devices as the grid changes from an (n) state to an (n-1) state, which are not
captured in a power flow analysis, time simulation is now more widely used as
a determinant for dynamic reactive support.
Figure 2-3 illustrates the form of dynamic response used in the Western
Electricity Reliability Council (‘WECC’) of North America as a determinant for
dynamic reserve.

(Source: WECC public documents)
In this form of dynamic response, the distinct criteria for voltage recovery are
specified for each of several time periods following the fault clearing portion
of the contingency, including:
a. Maximum transient voltage dip – the drop in pre-contingency voltage
measured during the first few cycles following fault clearing.
b. Time duration of voltage dip – the duration that voltage remains below
a specified value following fault clearing
c. Post-transient voltage – the voltage several minutes after fault
clearing when all relevant dynamic phenomena are quiescent in the
simulation. Note that this voltage may not necessarily coincide with
the power flow post-contingency voltage.
2.3. Planning Criteria Applied by Transpower
In a technical paper (see Reference 3 of Section 1.4) Transpower planning staff
described a set of performance criteria for dynamic analysis. This set provides a
basis for establishing voltage stability criteria that are based on dynamic simulation.
The key criteria specified in the paper are as follows.
•
Voltage must be greater than 0.5 pu immediately following an N-1 event
which removes an item of equipment from service without transmission
system short circuit fault.
•
Voltage must recover to above 0.8 pu in less than 4 sec following an n-1
event with a three-phase fault
•
Motor current must not be greater than 6 times the rated current for more
than 3 sec and not be greater than 3 times the rated current for 8 sec.
R125-07
Voltage Stability Study
12
Pterra Consulting
•
Voltage overshoot must be limited to below 1.3 pu.
•
Voltage overshoot must not be above 1.1 pu for more than 0.5 sec.
These criteria are consistent with the current and evolving practice in planning for
voltage stability in power systems. It is expected that the criteria will continue to
evolve as more information about the characteristic response of the grid to various
contingencies is obtained.
2.4. Proposed Planning Criteria for the Present Study
Considering the existing Transpower criteria, international practice and simulations
conducted of the South Island grid (see Section 4), following are criteria proposed
for use in this study:
•
A MW margin, measured on the PV curve of at least 5% from the annual peak
steady-state model total USI load, the 5% measured from one of the
following points on the PV curve: the nosepoint, the point where the power
flow solution fails to converge or the point where voltage dips below 0.9 pu,
whichever results in the lower margin.
•
Contingencies to test using dynamic simulations:
•
•
•
Design contingencies: Three-phase fault with normal clearing and singleline to ground fault with delayed clearing
•
Extreme contingencies: Loss of a bus section (without a fault applied)
Transient response:
•
The voltage to recover to at least 0.9 p.u. voltage8 in 5 seconds9 after the
clearing of the initial fault and disturbance for normal or design
contingencies, and
•
The voltage to recover to at least 0.6 pu voltage10 in 0.5 seconds for
extreme contingencies with no fault applied
Post-transient response: the voltage to recover to within 10% of the precontingency voltages, with no undamped oscillations after 30 seconds.
The above criteria is intended as a preliminary set of modifications to the existing
criteria used by Transpower, taking into account dynamic reactive response to
voltage stability. The criteria are further intended to be modified as more accurate
information becomes available and further system and load characteristics are
applied.
8
This is about the voltage level where distribution tap-changers are able to maintain voltage at customer
loads.
9
The 5 second target is a system-dependent characteristic. It marks the point in time when most of the
voltage transient responses from the initial contingency have rung down (but before the frequency
response from governors becomes evident). This is an aspect of the criteria that can be fine tuned over
time.
10
This is about the voltage level above the range of contactor tripouts (0.4 to 0.6 pu); hence the specific
criterion avoids motor trips on low voltage for short durations.

Section 3. Data and Assumptions
The databases used for this study were provided by Transpower. Some
modifications and clarifications were subsequently made to the models as
documented in this section.
3.1.1. Data for Steady-State Assessments
For the power flow model, Pterra developed a detailed model based on the model
case provided by Transpower, with minor adjustments to match the 2007 system
conditions. In addition, Pterra developed generator reactive capability (‘GCAP’)
curve models to supplement the power flow model. The purpose of GCAP models is
to provide for a means to reflect the steady-state reactive capability of the sending
end (Waitaki Valley area) and receiving end (USI) generators based on their real
power dispatch.
A summary of the items confirmed in relation to the power flow model follows:
•
Confirmed that the existing reactive devices as listed in Table 1 of the
Planning Study are modeled explicitly.
•
Removed cap banks at Ashburton (ASB).
•
Confirmed that dispatch is for winter wet conditions based on Table 5 of the
Planning Study.
•
Confirmed which of the transmission upgrades listed in Table 6 of the
Planning Study are modeled. Those that were not so modeled were added to
the power flow model.
•
Confirmed that the two circuits to Islington are bussed at Ashburton.
•
Confirmed the setting and operating mode of OLTC transformers.
•
Applied the GCAP data to the base case. This essentially sets the reactive
power limits for generators to the Qmax and Qmin limits specified by their
reactive capability curves.
•
Conducted an overload and voltage limit check and confirmed that the power
flow case is in compliance with Planning Criteria.
The resulting power flow after the above modifications was designated as the “Base
Case” power flow. It represents a condition where total South Island demand is
2253 MW under winter wet generation dispatch.
Additional power flow cases were developed representing future years by increasing
load at constant power factor, taking into account non-scaleable load.
3.1.2. Data for Dynamic Simulation Assessments
For the dynamic simulation model, Pterra reviewed the provided data and applied the
following changes and tests:
•
Reviewed machine model data versus manufacturer data provided.
•
Added excitation limiters where data was provided.

•
Revised exciter models based on manufacturer data provided.
•
Developed additional models for loads using a complex load configuration.
•
Added remote control setpoints for the SVDs at Islington.
The resulting database was tested for compatibility with the power flow Base Case to
ensure that all models are connected and the data is consisted with typical range of
values.
Exciter testing was conducted on this database with results that are generally within
the acceptable range of values and response. Plots of the exciter tuning are included
in Appendix B.

Section 4. Analysis and Results
This section presents the methodology, analytical results and discussion of voltage
stability assessments conducted under the Scope of Services.
4.1. Steady-State Assessment
The following analyses were conducted using steady-state methods (power flow):
1.
Contingency analysis
6.
Nose or PV curve analysis
7.
QV curve analysis
Each is discussed in the following subsections.
4.1.1. Contingency Analysis
An initial filtering of contingencies that impact voltage stability, steady-state
contingency analysis was performed. Since the analysis is performed at load levels
that may not be at or near where voltage stability occurs, at best the method
provides for a list of contingencies with a potential impact on voltage stability.
The 220 kV contingencies identified based on the magnitude of voltage dip are listed
in Table 4-1.

and the Christchurch area.
4.1.2. PV Curve Analysis
In the Planning Study, the P-V characteristic was developed by increasing USI
demand and monitoring voltage at the Islington 220 kV bus. The Planning Study
concludes that the critical voltage of the system is close to 1.04 p.u. The voltage
stability limit is in the range of 1188 MW Upper South Island (USI) load, taking into
account a 5% margin from the nose point.
R125-07

Using the Base Case described in Section 3.1.1, Pterra developed PV curves at
various load levels and various contingencies. The most limiting contingency is the
loss of the Islington-Tekapo B 220 kV line. This is consistent with the Planning Study
basis.
A useful measure of reserve for voltage stability is the MW margin measured from
the P-V curve. An example of the MW margin is illustrated in Figure 4-1. For the
purposes of this study, the steady-state voltage limit is defined as the lowest of the
following: the MW value at the nosepoint, the MW value at the point where the
power flow solution fails to converge or the MW value at the point where voltage
drops below 0.9 pu. The MW margin is determined with a safety margin of 5% of
the steady-state voltage limit.

The results indicate that the surplus transmission capacity available is less than 100
MW for the existing system operating during winter wet conditions. The most severe
contingency with respect to voltage stability is the loss of the Islington-Tekapo B 220
kV line. Plots of the PV curves for Islington and other buses are included in Appendix
C.
4.1.3. QV Curve Analysis
By means of QV analysis, the Planning Study determines that present reactive
support is exhausted when load demand (in USI) is about 1150 MW, or just after
year 2007.
A useful measure of reserve from QV Curve analysis is the reactive margin. This is
the measure of MVAR from the lowest point of the curve to the reactive supply curve
(either the Q=0 line or the curve/s of proposed capacitor/s). This is illustrated in
Figure 4-2.
Figure 4-2: Reactive margins determined from QV curves.
Using the Base Case as developed in Section 3.1.1, QV curves were developed for
various load levels and contingencies. The resulting reactive reserves are
summarized in Table 4-3.

The loss of the Islington-Tekapo B 220 kV line leaves the lowest MVAR margin of the
contingencies tested. The margin is relatively low compared to the total reactive
demand in USI, and indicates that additional reactive support will be needed with
load growth.
The plots of the QV curves are included in Appendix D.
4.2. Dynamic Simulation Assessment
Dynamic simulation assessment was applied to confirm the response characteristic to
various contingencies. Appendix F lists the various simulations performed. The plots
of stability cases are included in Appendix G.
The following subsections discuss the aspects of assessments:
•
Load modeling
•
Stability tests
•
Solutions for voltage stability prior to addition of new 220 kV line
4.2.1. Load Modeling
As load modeling was deemed to be a critical aspect of voltage stability of the South
Island, attention was given at the early stages of study to obtaining range of values
and characteristics to different possible load models.
We started by considering two load models:
•
PIQZ11 model for all load
•
Complex load model described in Reference 4 of Section 1.412.
To obtain a sense of the range of response, nomograms were developed for each of
the possible load models. The assumptions applied to the nomograms are:
•
No additional shunt compensation or SVD to the Base Case
•
Both the Islington SVC and synchronous condensers are remotely controlling
voltage at the Islington 220 kV bus
•
Solid 3-phase fault applied at Islington 220 at 0.1 sec, cleared in 120 msec,
with opening of the Islington-Tekapo B line. (This is the worst contingency as
identified in the steady-state assessment.)
•
Where there is motor contactor shedding, these are initiated at v<0.6 p.u.
11
Where the real power portion of the load varies as voltage (also referred to as “constant current or I”
characteristic) and the reactive portion of the load varies as the square of voltage (also referred to as
“constant impedance or Z” characteristic).
12
However, for this study, the constant power component of the complex load model has a braking
characteristic that starts at 0.7 p.u and changes the load-voltage characteristic as voltage drops below 0.7
pu.

•
Complex load is applied only to USI. The rest of the island load is modeled as
PIQZ
•
Response voltage is monitored at Islington 220 kV bus.
The following nomograms to study load characteristics were developed.
nomograms are shown in Appendix E.
The
•
Complex load (‘CLOD’)13 model with 38% motor load component and with a
portion of group 1 motor loads shed due to assumed contactor dropout.
Portions shed range from 35% to 100% (See nomogram 1). Non rotating
loads are modeled as PIQZ (46%) or constant P (15%).
•
Complex load model with motor load component of 9%, 19%, 29% and 38%
with no motor contactor shedding (See nomogram 2). Non rotating loads are
modeled as PIQZ or constant P.
•
Complex load model with 19% motor load component and with constant P
component of 0, 5, 10 and 20% (See nomogram 3). The balance of the loads
in each case is modeled as PIQZ. No contactor dropout is assumed.
Various load models were proposed based on the preceding nomograms. Each
proposed load model was tested over a range of load levels to measure the
maximum USI load level where proposed criteria are met and the approximate year
when the maximum level is reached. The summary of results is shown in Table 4-4.

Absent further reference for actual load-voltage response characteristic, it is difficult
to conclude just from simulations which would be an appropriate load model. One
can argue that given the P-V Curve maximum USI load of 1264 MW, normally a
conservative measure, that the dynamic load model should support at least 1275 MW
of USI load. Furthermore, the load model should be generally applicable to future
load conditions.
Hence, we can say that for a low risk model, Transpower can consider either:
•
A complex load model with 38% motor load, 15% constant P component (as
described in Reference 4 of Section 1.4) and the remainder modeled as PIQZ.
Of the motor load, 50% of the Group 1 motors have contactor shedding at
voltages below 0.6 pu (See nomogram 6).
•
A complex load model with 19% motor load component with no motor
shedding. Non rotating loads are modeled as PIQZ (61%) or constant P
(20%). No motor shedding. (See nomogram 7).
A moderate risk model is:
•
A complex load model with 19% motors, 10% constant P load16 and the
remainder as PIQZ (See nomogram 9).
Finally, a higher risk model is:
•
100% PIQZ model, i.e., no motors modeled explicitly (See nomogram 5).
Clearly there is a variety of choices each with significant impact on the reliability and
cost of the planned system.
For purposes of further study, we proceeded with the following:
•
The moderate risk model (as described above)
•
A low risk model - with 38% motor load, 15% constant P component and the
remainder modeled as PIQZ. Of the motor load, 50% of the Group 1 motors
have contactor shedding at voltages below 0.6 pu
In using these two models, two plans were developed, providing a range of solutions
that can be directly associated with load modeling risks.
4.2.2. Voltage Stability Tests
An initial screening of the possible contingencies was performed to identify the ones
which are critical to voltage stability. The list of contingencies tested:
16
The constant P component represents load that is not voltage-dependent during the transient.
Typically, this may comprise of power supplies and certain types of loads with electronic controls. Since
the penetration of this type of load is not generally high, it is reasonable to assume a smaller percentage.
Also, some of the load classified as constant P may be self-restoring load that has a fast time response.
But even in this case, self-restoration requires sensing and feedback response that would have transducer
and other time delays embedded in the response. It is more practical to assume this type of load as PIQZ
during the transient and self-restore in the post-transient.

Mvar capacitor, and the Livingstone line
9.
Loss of interconnector T7, the TKB line, and an ISL-CUL-WPR-KIK circuit
The tests were made at a load level of 2254 MW total South Island load, for each of
the low and moderate risk load models.
The most severe design contingency is the single-line-to-ground (SLG) fault at
Islington, cleared by the line to Tekapo B (contingency no. 6). In general, the SLG
contingencies are more severe than the three-phase (3ph) faults for the same fault
location and line outage. The extended duration of the SLG, 350 msec, with respect
to the 3ph fault, 120 msec, results in a slower recovery for voltages in the transient.
The most severe extreme contingencies involve either loss of the T6 (contingency
no. 8) or the T7 (contingency no. 8) connectors.
Stability tests were conducted on system response to the various contingencies at
higher levels of forecasted load. A summary of the test results is shown in Table
4-5.

Given that the earliest that a new 220 kV line can be put in service is 2014, there is
clearly a need for intermediate reinforcements for voltage stability. These are
addressed in the next sub-section.
4.2.3. Assessment of Possible Intermediate Solutions
In the timeframe between 2009 (when the first intermediate solutions may be
implemented) to 2014, the types of solutions to voltage instability would be
characterized as incremental and short-term. When a new 220 kV line is built
between Waitaki Valley and the Christchurch area, the intermediate solutions may
become superfluous or have a secondary function.
Hence solutions that are easy to implement and relatively cheap are desired. Also,
for as long as the solutions are economic, they may continue to be applied to further
defer the investment in a new 220 kV line subject to the aspects of technical
feasibility, reliability and controllability. Some of the solutions are as proposed in the
Planning Study. The solutions tested herein are as follows:
•
Switched capacitors under RPC control operating in corrective mode. These
would normally be offline, but are switchable during a transient at a
maximum delay of 2 seconds per block. The location is at Islington 220
where the existing RPC is located.19
•
Additional SVCs at Islington, Kikiwa and Ashburton in combination with fixed
capacitor banks.
•
Series compensation of lines between Waitaki Valley and the Christchurch
area – 50% on all four circuits
•
Bussing of all four 220 kV circuits between the Waitaki Valley and
Christchurch at Geraldine.
Feasible solutions based on the options listed above are measured in terms of the
highest SI total load supported while still meeting the proposed criteria. Table 4-6
shows a summary of feasible solutions for both the moderate risk and high risk load
models. A full list of all tested solutions is included in Appendix F.
17
Rounded to nearest 25 MW. Based on meeting the Proposed Criteria.
Taking into account a 5% margin on the forecasted load.
19
Operating capacitors banks on corrective mode during transients requires an intelligent controller such
as an RPC and switching through a breaker, or in other cases, using thyristor technology and controls
similar to those of an SVC. Attempting to implement this function via a voltage-sensing relay and breaker
alone could lead to incorrect switching. Care must be taken to ensure that the delta-V when the capacitor
switches in can be tolerated by equipment, noting that normally, the voltage at switching may be quite
low. This could lead to designs with smaller blocks of capacitors on individual breakers.

Following is a discussion of each of the proposed solutions.
1. For the Moderate Risk Load Model
a. Solution A. Switched capacitors in corrective mode respond during
transient conditions when the decision to switch in or out is made on
a short time frame and under depressed voltage conditions. As more
such banks are applied, smaller block sizes are required to avoid

switching over-voltages28. For Solution A, starting with 75 MVAR
blocks, the solution is limited to an incremental 50 MW of USI load.
Beyond this, the delta-V exceeds acceptable levels. With smaller
block sizes, the time delay as each block is switched keeps the
solution from being able to meet to the proposed transient criterion
(which specifies 5 sec to return voltage to 0.9 pu or above).
b. Solution B1-B4. The set of solutions B1 through B4 use a
combination of fixed capacitors and SVCs to meet the proposed
voltage stability criteria. Solution B1 starts with a 75 MVAR fixed
capacitor bank added at Islington in combination with an additional
SVC on T7 with a control range of +100/-100 MVAR. This
combination yields an incremental USI load capacity of 75 MW.
Adding an SVC at Kikiwa rated at +/- 60 MVAR would further increase
the USI supported load by 25 MW. In Solution B2, B1 is extended,
adding two 60 MVAR fixed capacitor banks at Ashburton. This
increases USI load capacity by 25 MW. Note the decreasing
MW/MVAR ratio, where MW is measured in terms of incremental USI
load, and MVAR in terms of additional capacitive capability. At very
low MW/MVAR ratios, starting from 0.5 and less, additional shunt
capacitors tend to be infeasible without being accompanied by
dynamic control range to mitigate high voltages and respond to
reactive demand during contingencies. The reason for this is that the
lower ratio requires increasing MVAR additions from capacitors, but
the large cap banks introduce over-voltages during normal if operated
in preventive mode or during switching conditions if operated in
corrective mode.
Solution B3 applies an additional SVC at Ashburton in place of the cap
bank from B2. USI load levels of up to 1575 MW, corresponding to
forecasted load for 2014, are possible with this approach. A wide
area RPC may be needed to coordinate the response of the dispersed
SVCs.
Solution B4 addresses the concern with overlapping control response
of SVCs at multiple sites29 (Islington, Kikiwa and Ashburton) by
placing a single large SVC installation at Islington. A large SVC, sized
+/- 500 MVAR in combination with fixed shunt capacitor banks offers
a solution for supporting higher levels of US load that comply with
28
For cases where high voltages are observed in simulation just after fault clearing, consideration could
be given to include some inductive range of compensator (i.e., thyristor-controlled reactor, TCR), which
would help to control the voltage, converting this into an AVC solution. Additionally, manufacturers may
implement strategies in the thyristor valve control circuit (associated with the thyristor-controlled
capacitor, or TSC, branch) to mitigate or self-protect the system and/or the thyristor valve from high
voltages. Some examples of mitigation measures are (1) temporarily “blocking” the thyristor valve firing
pulses for pre-defined overvoltage and/or undervoltage conditions, and (2) applying break-over diodes
and/or surge arresters across the thyristor valve.
29
Controlling multiple SVCs at different sites/substations requires specific studies to determine the
appropriate response rates for each of the SVCs while considering the combined effect of all SVCs acting
together (for all probable contingency conditions). Alternatively, wide area controller or RPC may be used
for the purpose of coordination.

planning criteria. However, this solution is subject to confirmation of
security against common mode failures, effects of harmonics and
excitation of resonant modes in neighboring facilities. At the time of
this report, no existing SVC of this control range yet exists.30 Given
these considerations, 615 MVARs of additional shunt capacitors in
bank sizes of 9x60 and 1x75 MVARS, in combination with the large
SVC can potentially support USI load of 1800 MW, or out to planning
year 2022.
c. Solution C considers the option of adding series compensation. For
study purposes, 50% compensation was applied to each of the four
existing 220 kV lines between Waitaki Valley and Christchurch.
Without any other additions to the Base Case, this solution can
support up to 1550 MW of USI load, or up to forecast year 2014.
Series compensation may require significant upgrades or revisions in
the protection schemes, in particular, relaying and monitoring that is
dependent on the line impedance, such as line relays. Once
implemented, the series capacitors tend not to be relocatable. And
with series compensation in place, future new transmission lines may
need series compensation as well. A further technical note about
series compensation is that the potential for subsynchronous
resonance impacts needs to be assessed.
Solution C can be extended to support additional USI load growth in
combination with shunt capacitors and SVCs. The limits on additional
USI load growth are subject to those technical issues noted in
solutions B3 and B4 above.
d. Solution D considers the bussing of four circuits between the Waitaki
Valley and the Christchurch area at a substation designated as
Geraldine. This solution reduces the net effect of the loss of the worst
contingencies – Islington to Tekapo B, and Islington to Livingstone –
by providing a switching station at Geraldine. This solution supports
up to 1575 MW of USI load, or up to a forecast year of 2015.
As with Solution C, this solution may be extended with the addition of
shunt capacitors and SVCs.
2. For the Low Risk Model
a. Using the Low Risk load model, wherein there is a larger component
of motor and constant power load than the moderate risk model,
Solutions B1, B2 and B3 provide minimal incremental capacity, up to
1375 MW of USI load, or until 2010.
The large SVC option for Solution B4, on the other hand, provides
support for up to 1750 MW of USI load, or until forecast year 2020.
The reason for the response is that the SVC offers dynamic control
30
The largest existing SVCs as of the date of this report are +500/-150 MVAR device in the Allegheny
Power service territory in Pennsylvania, USA, and the Chamouchouane SVC (actually two SVCs at one
site) rated +330/-330 MVAR in Quebec, Canada.

that mitigates the impact of the more severe motor and constant P
loads of the low risk model, better than the smaller SVCs in Solutions
B2 and B3. However, the technical concerns, noted in item 1a above
are still applicable and need to be addressed for the large SVC
solution.
b. Series compensation (Solution C) also provides a fairly high MW
margin supporting USI load of up to 1550 MW, or until 2014.
c. Bussing at Geraldine (Solution D) offers a modest increase in
supported USI load, up to 1400 MW or year 2011.
All of the assessed solutions to provide support against voltage instability offer some
level of additional USI load. A summary of the best solutions, in order of
effectiveness:
•
Large SVC in combination with fixed capacitor banks at Islington. This
solution has the potential for supporting levels of USI load up to 2022. In
combination with series compensation, even higher levels of USI load may be
supported. However, the technical issues noted in item 1b above need to be
addressed.
•
Series compensation. Technically, this offers additional MW capacity for up
to 2014 in either the moderate or the low risk load model. Because of this
characteristic, the solution addresses a wide range of risk associated with
load response, and offers a robust option for mitigating the need for a new
220 kV line.
•
Capacitors and SVCs at Islington, Kikiwa and Ashburton. Incremental
additions at the three sites provide for USI load of up to 1475 for the
moderate risk model and 1375 for the low risk model are possible.
Overall, the dynamic simulation results provide MW margins that are about the same
(for the low risk model) or a couple of hundred MW higher (for the moderate risk
model) than those of steady-state results using PV and QV curves. The dynamic
simulation results show an additional dimension of system response not available to
the steady-state models that allow differentiation amongst the potential mitigation
measures to defer the need for a new 220 kV line. Hence, dynamic simulation points
towards SVCs and series compensation as robust solutions to deferring the need for
a new 220 kV line.
4.2.4. Observability and Controllability Issues
As noted earlier in this Section, the high levels of compensation present a concern
for the observability and controllability of the South Island grid.
Observability is the aspect of the planned operating system that provides future
system operators with sufficient indicators to anticipate potential voltage instability.
The indicators need to be of a form that operators can observe and monitor in order
to have sufficient time to respond to a system disturbance. For voltage stability, the
traditional observed quantities are voltages at various nodes of the power system.
However, given that from both the PV curve and the dynamic simulation assessment
R125-07
Voltage Stability Study
28
Pterra Consulting
the pre-contingency voltage can be high, as much as 1.04 pu for events that may
lead to voltage instability, voltage may not be a sufficient monitored parameter if the
intermediate solutions are implemented.
To enhance observability in the future system, prior to the addition of a new 220 kV
line between Waitaki Valley and Christchurch, additional monitored parameters are
required. One of the most commonly used indicators is the reactive reserve. This is
a measure of the level of reactive output of generators and static devices. We
recommend that this measure not be determined from QV curves but from dynamic
simulation that identifies optimal levels of reactive output from various reactive
sources. One aspect of this measurement may be to consider SVCs as operating in
floating mode during normal conditions with the dynamic control range available for
contingencies. Other indicators that have been used in Europe and the United States
include the rate of voltage change per MW change in load, the rate of reactive output
change per MW change in load, and online dynamic security assessment tools.
Controllability is the aspect of the planned system that provides future system
operators with sufficient control and response capability to maintain voltage stability.
The controls available to the operators of today include dispatch, voltage schedules
and switching of capacitors and lines. At the levels of shunt compensation existing
and planned prior to the addition of a new 220 kV line the sensitivity of voltage to
the controls is quite high. By this we mean that small shifts in dispatch and voltage
schedules may result in significant shifts in the voltage stability of the system. The
primary causes of this sensitivity are shunt compensation devices in SVCs and
capacitor banks whose reactive output vary as the square of the terminal voltage.
As voltage shifts take place, the total reactive output from the static devices
changes, and needs to be balanced by the reactive output from rotating devices. In
the case of USI, the closest rotating machines are at Coleridge, Cobb and Kumara.
However, these units are relatively small, and the larger machines are located in
Waitaki Valley, on the other end of relatively long 220 kV lines. To improve
controllability, additional supervisory and supplementary controls may be specified.
For example, the RPC at Islington may be designed to respond to voltage stability
conditions for the whole of USI instead of monitoring local voltage. Another option is
a wide area RPC that controls switching of SVDs in various locations in USI.
As MW margins decrease in the South Island, and mitigating measures are
implemented to defer the need for a new 220 kV line, it would be of benefit to future
system operators to provide increased capability for observability and controllability
of the power system.
4.2.5. Sensitivity Analysis
Additional assessments were requested by Transpower to consider the sensitivity of
the dynamic simulation results to other types of contingencies, classified as extreme
contingencies. Specifically, the following contingencies were tested (numbering
continued from Section 4.2.2):
10. Autoreclose onto fault event
o
3ph fault at Islington cleared by opening the ISL-TKB line at both ends
after 120msec.

o
Auto-Reclose the line onto the fault 6.5 seconds later.
o
Clear the fault after 120 msec by opening the ISL-TKB line at both ends
(and leaving it open).
11. Bus section outage with fault31
o
a 3 phase fault on ISL-TKB line occurs close to Islington 220 bus
o
At the TKB end of the line, the line breaker opens correctly after 120
msec. However at the Islington end of the TKB-ISL line the breaker
remains closed (i.e. has stuck) when allows the fault to persist.
o
Breaker failure detection operates after 300 msec to remove a bus section
at Islington and hence clear the fault.
o
This results in loss of ISL-TKB line, the T7 interconnector, and the ISLWPR-CUL-KIK line, i.e. refer to contingency #9 (sec 4.2.2 of report).
12. Double circuit outage32
o
a 3 phase fault at ASB 220 cleared by opening both ASB-TIM-TWZ circuits
after 120 msec.
o
Successful auto-reclose after 1 second of both circuits at Twizel end and
Ashburton end.
o
Successful reclose of circuits at Timaru 220 occurs after 3 seconds.
Applying the above contingencies to the Moderate Risk load model and the ‘B4’
solution of Table 4-6, the resulting maximum USI load that meets the proposed
voltage stability criteria are summarized in Table 4-7.

110, and 48352 TMK110-B 110. The load in the island is much greater than the generation. Hence, this
island is assumed to shut down, and remain disconnected through the remainder of the simulation.

Furthermore, reactive requirements to allow support for up to 1800 MW of USI load
for each of the additional contingencies were determined. These are summarized in
Table 4-8. The reported reactive reinforcements are in addition to the ‘B4’ solution.

The double circuit outage contingency (no. 12) is no more severe than the worst
normal or design contingency (single line to ground fault with delayed clearing).
Hence stability countermeasures specified in Table 4-6 would also provide support
for these types of extreme contingencies.
The solution identified as ‘B4’ will not be sufficient to support USI load beyond 2015
for the extreme contingencies involving autoreclosure on fault events (contingency
no. 10) and bus section outage with fault (contingency no. 11). In order to be able
to support USI load of up to 1800 MW under these extreme contingencies, an
additional +500 MVAR SVC is needed at Islington.

Section 5. Conclusions
Pterra was tasked with reviewing Transpower technical reports and documents and
confirming simulation results. To this end, we conclude that
•
Transpower has conducted a thorough and technically correct assessment of
the USI system that is consistent with international planning practice.
•
Pterra has provided comments on planning criteria in Sections 2.2 and 2.4 of
this report that offers suggestions for further aligning Transpower practice
with international standards. A proposed set of planning criteria for voltage
stability is included in Section 2.4.
•
Pterra confirms the results of the PV and QV analysis by Transpower through
independent simulations using the PSS/E software.
Pterra was further tasked with performing dynamic simulations related to voltage
stability of the Upper South Island. The dynamic simulations were performed to
determine the appropriate load and equipment modeling, to identify the levels of USI
load supported by various mitigating measures to defer a new 220 kV line between
the Waitaki Valley and Christchurch and to assess controllability and observability to
voltage stability of the planned power system. Based on these assessments, we
conclude that
•
•
Load modeling has a significant impact on the dynamic simulation assessment
for voltage stability of USI. We qualify various load models in accordance
with the level of risk that the model will provide sufficient MW margin to
support additional load in the USI. Two proposed models for conducting
dynamic assessments are:
o
The moderate risk model is a complex load model with 19% motors
and with 10% constant P load component
o
The low risk model is a complex load model with 38% motor/15%
constant power load and 50% group 1 motor contactor shedding
Limits on additional USI load supported by the existing system, as determined
using dynamic simulation, are similar or greater than those determined by PV
and QV curve methods. Hence, steady-state analysis provides a conservative
measure of voltage stability.
• Dynamic simulation assessment provides improved differentiation of options
to defer the need for a new 220 kV line. Of several options studied, the
following offer the best potential to support additional USI load, in order of
effectiveness:
o
Large SVC in combination with fixed capacitor banks at Islington.
This solution has the potential for supporting levels of USI load up to
2022. In combination with series compensation, even higher levels of
USI load may be supported. However, certain technical issues
beyond the scope of this study need to be addressed.

•
Series compensation. Technically, this offers additional MW capacity
for up to 2014 in either the moderate or the low risk load model.
Because of this characteristic, the solution addresses a wide range of
risk associated with load response, and offers a robust option for
mitigating the need for a new 220 kV line.
o
Capacitors and SVCs at Islington, Kikiwa and Ashburton. Incremental
additions at the three sites provide for USI load of up to 1475 for the
moderate risk model and 1375 for the low risk model are possible.
o
Extreme contingencies involving double circuit outages are no more
severe than the worst normal or design contingency (single line to
ground fault with delayed clearing). Hence stability countermeasures
specified for normal contingencies would also provide support for these
types of extreme contingencies.
o
Extreme contingencies involving autoreclosure on a fault event and a
bus section outage with fault are more severe than the most severe
normal contingency. Hence, in order to mitigate these extreme
contingencies, solutions applied to normal contingencies need to be
augmented beyond 2015. For example, an additional +500 MVAR SVC
at Islington is needed to support USI load of up to 1800 MW under
these extreme contingencies.
As the available surplus transmission capacity decreases in the South Island,
and mitigating measures are implemented to defer the need for a new 220 kV
line, it would be of benefit to future system operators to provide increased
capability for observability and controllability of the power system.
