Fort Randall Unit Modeling

Part 1

General Information

1. GENERAL: This is a non-personnel services contract to provide Fort Randall Unit Modeling. The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.1 Description of Services/Introduction: The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to perform Fort Randall Unit Modeling as defined in this Performance Work Statement except for those items specified as government furnished property and services. The contractor shall perform to the standards in this contract.

1.2 Background: Generator owners are required to provide dynamic data information to transmission operators per North American Electric Reliability Corporation (NERC) standard MOD-32-1. Model validation testing of generators, governors, exciters, and power system stabilizers (PSSs) provide the information needed to meet the requirement. A model validation report that demonstrates compliance with all current NERC and Southwest Power Pool (SPP) requirements must be prepared and submitted to the U.S. Army Corps of Engineers (USACE) Omaha District (NWO) Reliability Coordinator.

1.2.1 Occasionally, adjustments to governor and/or excitation system settings are also needed for unit stability and model validation requirements. For this contract, no major tuning is anticipated. Additionally, no PSS tuning or tuning study is anticipated.

1.2.2 The NERC regional entity for compliance monitoring and enforcement for Omaha District Dams and one is the MRO region. It is the contractor’s responsibility to research and demonstrate compliance with all MRO requirements beyond NERC requirements.

1.3 Scope: The Contractor shall perform the testing on the eight hydro generator units at the Fort Randall Power Plant. The Contractor shall at a minimum provide a test team with one professional engineer, and all instruments, meters, transducers, and equipment required to perform testing. The Contractor shall perform the specific tasks listed in Part 5. All models and reports shall meet the requirements of SPP MDWG Model Development Procedures Manual v11.pdf, Ch 13, NERC MOD-32-1, MOD 25-2, MOD 26-1 and MOD 27-1.

1.3.1 All eight units at Fort Randall are identical. The first unit under outage shall be designated as the primary unit which shall require complete testing and the remaining units shall be designated as a sister units requiring cursory tests to compare the performance to the primary unit. IEEE standard models and parameters compatible with NERC / MRO unit modeling guidelines shall be provided for all generators and exciters. Models must be on the Acceptable Model List on the NERC SAMS webpage

1.4 Period of Performance: 240 days. All equipment to be tested will be available during one site visit with no intentional delays between testing units. Test dates will be determined in consultation with the O&M Supervisor at each project. The mutually agreeable dates shall be approved by the Government. Contractor will request dates to perform modeling unit tests. Testing may be requested from Jun 1-Nov 30 2021.

During the course of the tests, each unit will be available to be operated over a range of its rated capability, from speed-no load (not synchronized) to full load and maximum over and under-excited.

SPECIFIC TASKS

5. Specific Tasks:

5.1) Personnel and Equipment. Contractor shall provide test personnel and test equipment necessary for model validation testing on the governors, exciters, and generators. Test personnel shall have experience both with the Contractor’s test equipment and test procedures, and with the operating functionality and configuration of the type of governor or exciter (both manufacturer and model) to be tested. The Government will provide powerhouse operators and technicians to participate in performing the various tests as described in the approved and agreed upon test procedures.

5.2) Test Procedure. Contractor shall prepare for approval detailed test procedures for performing model validation testing of the governors, exciters, and generators. This shall include all required connections, test equipment, test sequence, measurements, and adjustments. The contractor shall provide a detailed test procedure for each unit, two weeks prior to being on-site.

5.3) Baseline Generator Validation Testing. Contractor shall perform steady-state testing to develop and validate the generator characteristics, including magnetic characteristics. Contractor shall further develop dynamic parameters through transient testing. Steady state test results shall be submitted to the Government in a tabular format accompanying graphs demonstrating simulation and equation matching to acquired steady state data. Parameters determined through review and calculation of parameters from drawings and nameplate data shall be noted and the equations shown.

5.4) Model Validation Testing of Exciters. Contractor shall perform testing and gather information necessary to determine the dynamic responses and build, within standard SPP model library models, if appropriate, a dynamic model to describe the excitation system. Contractor shall validate the excitation system model by comparing computer simulations representing the approximate system conditions during testing and displaying test and simulation results on overlaying graphs.

5.5) Model Validation Testing of the PSS. Contractor shall perform testing and gather information necessary to determine the dynamic responses and build, within standard SPP model library models, if appropriate, a dynamic model to describe the PSS.

Contractor shall validate the PSS model by comparing computer simulations representing the approximate system conditions during testing and displaying test and simulation results on overlaying graphs.

5.6) Overall Dynamics Validation. The Contractor shall submit graphs showing good matching between MW and mega-volt-amperes-reactive VAR (MVAR) dynamic responses to online excitation voltage reference steps of at least 2% positive and 2% negative and online power (speed) reference steps of at least ½% positive and ½% negative. The PSS damping effectiveness - if implemented and usually enabled during operation - to a voltage reference step of at least 2% positive and 2% negative shall be demonstrated by comparing MW amplitude and oscillations with PSS on and off.

Contractor shall provide graphs of sufficient size and clarity to demonstrate matching between ramp rates, overshoot, time constants, steady state settling, and other parameters necessary to validate dynamic simulation matching to actual tests. The Contractor shall submit comma-separated value (CSV) raw test data and simulation data with time in column 0, column headers, and scaling factors to allow for reproduction and review of the printed graphs.

5.7) Calculations, Data, and Formulas. The Contractor shall provide a record of the calculations made to support the model validation analysis, records of data taken, and formulas. The report shall contain calculations and formulas necessary to describe interpolations or calculations from gathered parameters to determine model parameters.

5.8) Draft model validation analysis and test report. The Contractor shall submit a test report that includes a subjective evaluation of equipment performance as well as the complete generator, turbine/governor, exciter, and PSS models with correct model parameters. Contractor shall compare actual and simulated data to validate accuracy of models. The model parameters submitted shall be acceptable to SPP for dynamic simulation purposes. This shall be submitted not more than 45 days from completing the on-site tests. Government will have 21 days to review and provide comments to the contractor.

5.9) Final model validation analysis and test report. The Contractor shall submit a final test report incorporating Government review comments or providing responses to comments for non-concurrence. The final test report shall include a subjective evaluation of equipment performance as well as the complete generator, turbine/governor, exciter, and PSS models with correct model parameters. Contractor shall compare actual and simulated data to validate accuracy of models. The model parameters submitted shall be acceptable to SPP for dynamic simulation purposes. This shall be completed 30 days after Government provides comments to the contractor.
