Idaho Power 2024 BLPR1 MOD-026-1 Validation Procedure
MLPR1 MOD-026-1 Validation Procedure
Discussion
The purpose of MOD-026-1 is to verify the generator excitation control system or volt/var
control function dynamic models. The models are used by planners for system stability
simulations.
This document provides direction for data collection to update the existing genrou model to
gengec format and validate the model per the NERC 10-year model validation requirements.
The staged testing consists of saturation, V-curve (sister unit) and reactive limits, and dynamic
voltage reference step test with the PSS on and off.
e This is unique testing as most generators have been converted to the gentpj model.This will be
the remaining unit to be converted at the Brownlee Power Plant.Otherwise, saturation and V-
curve data would not typically been needed.
Pre-Data Collection / Testing Coordination
This testing requires the coordination and scheduling with Operations and the Transmission
Operator. A calendar notification should be sent in advance to the following participants.
• Plant Operators and Leaders
• PP Generation Dispatch
• Real Time Balancing Operations Leader
• Day Ahead Balancing Leader
• Power Production EE MOD-026 Custodian

There is a possibility this testing may result and re-tuning or additional data request. That work
may be scheduled later with additional/updated procedures.
Procedure
The testing control and record measurements are performed using the unit control panel and
the DECS400 excitation controllers.

The Procedure section is mandatory and uses a playscript writing style (who/does what).
Use this section to identify the position title of the person performing the action, and to
describe the sequential steps required to complete the procedure.
The following example describes the basic process an employee would use to apply for a raise
at the U've Got 2B Kidding Company.

5. Review the form and authorize the raise, if appropriate, by signing the bottom of the form.
6. Return the form to the resource leader.

7. Notify the employee of the decision.
8. If the raise was granted, submit the form to the Payroll department.
Unit Operation
The unit is to be loaded above any rough zones at unity to begin. The units is to remain stable
for 5 minutes at unity. Its is preferred to be loaded around 80% of the operational rating.
• PSS will be ON and OFF for testing as specified below.
• The unit must be in manual control, as AGC can interfere with the testing.
• The testing is not to exceed any Voltage, UEL, or OEL Limits.
It is anticipated this unit is Online and running at normal operation.
