1. Executive Summary
A 50 MW peaking gas turbine generator is being installed near Glendive, MT on the
same site of the existing Glendive #1 peaking gas turbine generator. The Visual
Overview on page 3 and Glendive Turbine Jct Sub Switching Diagram on page 4,
identify the site of installation, configuration, and service territory of Montana-Dakota
Utilities Co. (MDU), all of which reside within the ND exporting interface (NDEX).
The primary purpose of the Glendive #2 peaking gas turbine generator is to meet summer
peak demand obligations for MDU network service customers.
A phase 1 system impact study separate from this interconnection evaluation study has
demonstrated no significant thermal or steady state voltage impacts to the system with
current system loads and approved transactions.
Similarly, this interconnection evaluation study demonstrates there are no significant
system impacts to local stability, given the implementation of generator tripping for all
but fast clearing line-to-ground faults on the Glendive CT – Dawson 115 kV line. Till
such time line protection is installed to discriminate adequately between single-phase and
multi-phase faults, both Glendive generators will be issued an unqualified trip for loss of
the Glendive CT – Dawson 115 kV line. The Glendive CT – Dawson 115 kV line is less
than 8 miles in length, so exposure to generator tripping is not significant even with the
existing protection.
With the addition of the Glendive #2 generator, there are no impacts (actually a slight
improvement) to regional stability for the worst system intact ND disturbance. For
incremental impact of scheduling 50 MW from Glendive #2 to MDU load, see Groton &
Wahpeton Voltage Sensitivity for CU Bipolar Block with Plant Trip – Full Scale and
Expanded Scale on pages 139 and 140 respectively.
MDU personnel have evaluated short circuit duty of equipment in the vicinity of the
Glendive #2 generator installation, and all existing equipment was found adequate.
A preexisting condition for Ft. Peck instability was discovered for a close-in 3-phase fault
on the Glendive CT – Dawson 115 kV line; given the modeling assumptions for 2nd zone
protective relaying at Dawson. The installation of Glendive #2 generator does not
exacerbate this preexisting condition or increase the probability that such an event would
occur. Investigation is under way to see if existing system protection adequately covers
this condition or if additional remedies such as pilot relaying will have to be
implemented. Until such time this condition has been evaluated and/or remedied, the
exposure for this event is limited to a 3-phase (perhaps also phase-to-phase) fault within 2
or 3 miles of the Glendive CT sub on the Dawson 115 kV line. The minimal exposure is
accentuated by the fact that this event has not occurred in all the years of the existing
system configuration.

Powerflow Base Case Information
6.1.1 Powerflow Base Case Summary and Their Application to Dynamic Analysis
Three 2002 summer off-peak NMORWG-compliant powerflow cases (see highlighted/underlined cases prefixed in the table below) were utilized
in this interconnection study, all of which were derived from the companion system impact study for MISO Transmission Service Requests
#75008893 & #75176496 (MISO Ref. A045 SIS).
For purposes of local stability analysis, the “gaa” and “gae” cases were utilized in dynamic simulations of preexisting conditions for the
Glendive 1 generator being off line and on line respectively. The “gag” case was utilized in dynamic simulations of the Glendive 2 generator
being on line with the existing Glendive 1 generator.
For purposes of transient voltage sensitivity analysis to the ND exporting interface, comparisons or transient voltage at Groton and Wahpeton
were provide for the Glendive 2 generator being off line in the “gaa” case and on line in the “gae” case.
All three of these cases had the Miles City DC scheduled at 150 MW W-E, the Rapid City DC at 200 MW E-W, and the Boundary Dam – Tioga
phase shifter scheduled 165 MW N-S. The output of the Glendive generators was scheduled to MDU network load.

PSSE DOCU of Glendive Generator Dynamic Data
Although this interconnection study is for the Glendive 2 generator, dynamic modeling
data for the Glendive 1 generator is documented below as well for comparison.
Particularly noteworthy is the disparity in the “H” constant between the units, i.e. 5.91 for
Glendive 1 and 1.23 for Glendive 2. The Glendive 2 turbine is an aero-derivative engine
and as such has a much lower inertia than Glendive 1. These differences in inertia are
readily apparent in the different modes of oscillation during dynamic simulations.

Assumptions for Breaker Clearing Sequence, Timing, and Zone 1 Reach
The following sequence and timings were applied uniformly for the step-distance relay and breaker failure simulations on the
Glendive CT – Dawson 115 kV line and the Glendive – Baker 115 kV line. In conformance with NERC standards, only L-G
faults were simulated simultaneous with a stuck breaker condition. To be conservative, zone 1 was assumed to reach only to
70% of the line during intermediate clearing.

Fault Data Derivation
6.6.1 Influence of Glendive Generator Status on Fault Derivation
All fault data was calculated with both Glendive generators on line. Since (1) positive sequence data is inherently updated with
powerflow topology changes, and (2) zero sequence data is insensitive to Glendive generator status while the generator step-up
transformers (grounded wye on 115 kV) remain in service for generator breaker tripping; the overall results for L-G fault calculations
are not substantially compromised by the uncorrected negative sequence impedance for a Glendive generator status change.
Although the modeling compromise is small when one or more of the generators are off line, the simulated deviation from actual
conditions errors on the safe side. 3-P faults are not compromised at all.
6.6.2 Influence of Zone 1 Reach
To preclude optimistic deterministic results for impedances associated with end-of-line faults, the fault impedances for open-ended
lines were assumed to be at 70% of the line length during intermediate clearing. This allows for the possibility that zone 1 (or
ground instantaneous) high-speed clearing does not actually reach the aspired 90% of line length.

Stability Plots
The following subsections have disturbances identified by a unique 3-character
power flow case prefix and a 3-character fault identifier.
To get a description of the 3-character powerflow case prefix, see section 6.1.1
Powerflow Base Case Summary and Their Application to Dynamic Analysis
starting on page 9.
To get a description of the 3-character fault prefix, see the section by the same
3-character name starting in section 6.8 Special Fault Definition Command
