General
The turbine-governor model is linked to one or two synchronous generators and determines
the shaft mechanical power (PMECH) or torque (TM) for the generator model.
In old Simpow turbine models, the turbine are composed of two models
- One Governor (Input = Speed, output = Gate)
- One Turbine (Input = Gate, Output = TM)
In new dynamic simulator the turbine models include the governor part.
One Turbine (Input Speed, Output = TM)
Note: The old Simpow models are also supported in new Dynamic simulator.
ENTSO-E, an association of the European electricity transmission system operators, selected
the Common Information Model (CIM) standards of the International Electrotechnical
Commission (IEC) as a basis for its own CIM standards. These standards aim at ensuring the
reliability of grid models and market information exchanges.
In 2013, ENTSO-E adopted a new standard for grid models exchange called the Common Grid
Model Exchange Standard (CGMES). The CGMES is a superset of the IEC CIM standards
(belonging to IEC CIM16). It was developed to meet necessary requirements for the
transmission system operators, which exchange data in the areas of system operations,
network planning and integrated electricity markets.
All the CIM/CGMES regulators models are included in NEPLAN Power System Analysis Tools.
Per Unit (p.u.) System:
All p.u. values are based on the machine ratings.

Governor mechanism time constant. It represents the natural
valve positioning time constant of the governor for small
disturbances, as seen when rate limiting is not in effect..
Turbine power time constant . It represents delay due to
internal energy storage of the gas turbine engine. T2 can be
used to give a rough approximation to the delay associated with
acceleration of the compressor spool of a multi-shaft engine, or
with the compressibility of gas in the plenum of the free power
turbine of an aero-derivative unit, for example.
Turbine exhaust temperature time constant. It represents delay
in the exhaust temperature and load limiting system.

TURBINE - GGOV1
General model for any prime mover with a PID governor, used primarily for combustion turbine
and combined cycle units.
This model can be used to represent a variety of prime movers controlled by PID governors. It
is suitable, for example, for representation of :
- Gas turbine and single shaft combined cycle turbines
- Diesel engines with modern electronic or digital governors
- Steam turbines where steam is supplied from a large boiler drum or a large header
whose pressure is substantially constant over the period under study
- Simple hydro turbines in dam configurations where the water column length is short
and water inertia effects are minimal.

0 = fuel flow independent of speed
1 = fuel flow proportional to speed.
Notes
1. Per unit parameters are on base of TRATE, which is normally the MW capability of
the turbine.
2. The range of fuel valve travel and of fuel flow is unity. Thus the largest possible
value of VMAX is 1.0 and the smallest possible value of VMIN is zero. VMAX may,
however, be reduced below unity to represent a loading limit that may be imposed by
the operator or a supervisory control system. For gas turbines VMIN should normally be
greater than zero and less than WFNL to represent a minimum firing limit. The value of
the fuel flow at maximum output must be less than, or equal to unity, depending on the
value of KTURB.
3. The parameter TENG is provided for use in representing diesel engines where there
is a small but measurable transport delay between a change in fuel flow setting and the
development of torque. Teng should be zero in all but special cases where this
transport delay is of particular concern.

4. The parameter FLAG is provided to recognize that fuel flow, for a given fuel valve
stroke, can be proportional to engine speed. This is the case for GE gas turbines and
for diesel engines with positive displacement fuel injectors. Wfspd shou ld be set to
unity for all GE gas turbines and most diesel engines. FLAG should be set to zero
where it is known that the fuel control system keeps fuel flow independent of the engine
speed.
5. The load limiter module may be used to impose a maximum output limit such as an
exhaust temperature limit. To do this the time constant TFLOAD should be set to
represent the time constant in the measurement of temperature (or other signal), and
the gains of the limiter, KPLOAD, KILOAD, should be set to give prompt s table control
when on limit. The load limit can be deactivated by setting the parameter LDREF to a
high value.
6. The parameter DM can represent either the variation of the engine power with the
shaft speed or the variation of maximum power capability wit h shaft speed. If DM is
positive it describes the falling slope of the engine speed verses power characteristic
as speed increases. A slightly falling characteristic is typical for reciprocating engines
and some aero-derivative turbines. If DM is negative the engine power is assumed to
be unaffected by the shaft speed, but the maximum permissible fuel flow is taken to fall
with falling shaft speed. This is characteristic of single-shaft industrial turbines due to
exhaust temperature limits.
7. This model includes a simple representation of a supervisory load controller. This
controller is active if the parameter KIMW is non-zero. The load controller is a slow
acting reset loop that adjusts the speed/load reference of the turbine governor to hold
the electrical power output of the unit at its initial condition value. This value is stored in
the parameter PMWSET when the model is initialized, and can be changed thereafter.
The load controller must be adjusted to respond gently relative to the speed governor.
A typical value for KIMW is 0.01, corresponding to a reset time of 100 seconds.
8. The parameters ASET, KA, and TA describe an acceleration limiter. TA must be non zero, but the acceleration limiter can be disabled by setting ASET to a large value, such
as 1.
9. The parameter, DB, is the speed governor dead band. This parameter is stated in
terms of per unit speed. In the majority of applications, it is recommended that this
value be set to zero.
10. The parameters TSA and TSB, are provided to augment the exhaust gas
temperature measurement subsystem in gas turbines. For example, they may be set to
values such as 4., 5., to represent the ‘radiation shield’ element of large gas turbines.
If both parameters are omitted, they default to 1.0.
11. The parameters RUP and RDOWN specify the maximum rate of increase and
decrease of the output of the load limit controller (KPLOAD/KILOAD). These
parameters should normally be set, or defaulted to 99/-99, but may be given particular
values to represent the temperature limit controls of some GE heavy-duty engine
controls. If both parameters are omitted, they default to 99 and –99. (In NEPLAN the
parameters RUP and RDOWN are not used)
12. The fuel flow command fsr is determined by whichever is lowest of fsrt, fsra, and
fsrn. Although not explicitly shown in the GGOV1 diagram, the signals that are not in
NEPLAN AG Oberwachtstrasse 2 CH 8700 Küsnacht ZH

www.neplan.ch
21
control track fsr so that they do not “windup” beyond that value. This represents GE
gas turbine control practice but may not be true for other controller designs.
13. As shown in the GGOV1 diagram, when KPGOV is non-zero, the governor PI
control is implemented to “track” fsr to prevent windup when fsr is limited by another
signal (fsrt, fsra) or VMAX/VMIN. If KPGOV is zero, the integral path is implemented
directly. The same applies to the load limiter PI control with regard to KPLOAD.
14. PREF has units of p.u. speed.

Notes
1. The frequency-dependent limit reduces the VMAX limit on fuel flow signal (fsr). For
normal operation, the limiter performs no action. When frequency (generator speed)
drops below FLIM1, the highest frequency data point, the desired value for the power
limit (PLIM) is determined by linear interpolation between associated data pairs. The
maximum value of the limiter (VMAX) will ramp to the fsr value corresponding to PLIM
(PLIM / KTURB + WFNL) at the PRATE ramp rate. PLIM will be updated as frequency
changes. If frequency subsequently rises back above FLIM1, the value of the limit will
ramp up at the rate PRATE back to the normal value of VMAX.
2. The frequency-dependent limit is defined by a set of up to 10 pairs of points relating
frequency (generator speed in Hz.) and power. The points must be monotonically
decreasing in both the magnitude of frequency and power. If fewer than 10 points are
needed to define the relationship, values of zero must be entered for the remaining
frequencies and power limits. The value of the last non-zero data pair are used as a
lower limit, that is, the last two values are not extrapolated to calculate lower power
limits. If there is only one set of frequency and power limit, those values will be used as
a single limit of power applied at that frequency and below.
3. Refer to GGOV1 model for other notes. Aside from the frequency-dependent limt,
GGOV2 is identical to GGOV1, except that the temperature fuel command fsrt does not
track fsr when it is not in control. Instead, it stays at its upper limit (1.).
4. The KPGOV/KIGOV and KPLOAD/KILOAD controllers include tracking logic to
ensure smooth transfer between active controllers. This logic is not shown on the
GGOV2 diagram.

Notes
For a tandem-compound turbine the parameters K2, K4, K6, and K8 are ignored. For a crosscompound turbine, two generators are connected to this turbine-governor model.
Each generator must be represented in the load flow by data on its own MVA base. The
values of K1, K3, K5, K7 must be specified to describe the proportionate development of
power on the first turbine shaft. K2, K4, K6, K8 must describe the second turbine shaft.
Normally K1 + K3 + K5 + K7 = 1.0 and K2 + K4 + K6 + K8 = 1.0 (if second generator is
present).

TURBINE – TGOV5
TGOV5 is a model of a steam turbine and boiler that represents governor action, main, reheat
and low-pressure effects, including boiler effects. The boiler controls will handle practically any
mode of control including coordinated, base, variable pressure, and conventional. The control
mode is selected by the proper choice of constants.
