PART 3 EXECUTION

3.1 Model Validation Procedures

Submit Model Validation Test Procedures. The Contractor shall prepare for approval detailed field test procedures for model validation testing for the generator , governor , exciter , and Power System Stabilizer (PSS) .

Provide a detailed step-by-step procedure of all required connections, test equipment, test sequence, operations, measurements and adjustments, and a list of the proposed dynamic simulation models. Testing and reporting shall be completed to satisfy the specific requirements of WECC in addition to the NERC requirements noted in "Applicable NERC standards." Approval of the test procedure does not release the contractor from the responsibility of testing and preparing a report that is acceptable to WECC. The contractor is responsible for researching all Generator Owner WECC requirements.

3.2 Personnel Qualifications

Submit Personnel Qualifications for Model Validation Testing. Test personnel shall have experience with the contractor's test equipment and test procedures and with the operating functionality and configuration of the type of governor and exciter (both manufacturer and model) to be tested. The test personnel must have experience performing model validation testing at a minimum of five (5) different generating plants in the past two (2) years. Contractor shall submit for approval a resume and experience list of the individual(s) who will perform the testing and the

SECTION 48 70 01.00 26 Page 4 individual(s) who will be the knowledgeable exciter technician or engineer. One qualified individual may perform both roles.

3.3 Model Validation Field Testing

a. Field Testing. Test the generator , governor , excitation system , and PSS in accordance with WECC and listed NERC requirements as necessary to demonstrate compliance.

b. Contractor Supplied Items. The contractor shall supply the following:

(1) All equipment, materials, personnel, and any and all services as required in connection with generator, governor, and excitation system model validation testing (this includes, but is not limited to, test equipment, laptops, and software);

(2) A knowledgeable exciter technician or engineer to provide onsite support during the described testing;

(3) All software as necessary for the knowledgeable exciter technician or engineer to program and operate the exciter during testing;

(4) Provide wiring termination strip to Government for connection to Government owned equipment and control systems, as described in the test procedure;

c. Government Support During Testing. The Government will provide the following support for testing:

(1) Powerhouse operators to operate government owned equipment and control systems as described in the approved written test procedures;

(2) Electricians to perform modifications to unit controls if needed for the tests as well as perform all wiring connections to Government owned equipment;

(3) Access to AC power outlets and/or extension cords in the area where the data recording equipment will be used;

(4) Previously prepared validation and modeling reports, if available;

(5) Equipment schematics or elementary drawings as requested by Contractor (if available).

(6) Equipment operation and maintenance manual as requested by Contractor (if available).

3.4 Model Validation Reporting

a. Computer Simulations. Perform computer simulations to ensure that the generator, governor, exciter, and PSS models, with parameters corresponding to as-left equipment settings, represent equipment dynamic performance with sufficient accuracy for power system stability studies. Models shall be standard models used in the simulation program or listed in IEEE 421.5 . Models shall be selected

SECTION 48 70 01.00 26 Page 5 to appropriately model the equipment. Custom models, if needed, shall be coordinated with WECC.

b. Model Validation Test Report. The Contractor shall submit a test report includes direct comparisons of actual dynamic performance with model predicted performance overlaid. The report shall includes a subjective evaluation of equipment performance as well as the models and the correct model parameters presented in a format suitable for transmittal to WECC. The report shall include a generator capability curve verified through testing. The Contractor shall be available to respond in writing to inquiries from WECC regarding test procedures and results. All deliverable products and working papers shall be the property of the U.S. Government. Procedures and reports shall be provided as Microsoft Word files.

c. Raw Test Data. Provide the raw test data in comma separated values (CSV) format on either a compact disc or digital video disc. Create the file names for the CSV files such that it is apparent which facility, unit, and test is being completed. Provide either as a header to columns or as a separate key file the contents and scaling factors for all columns.

d. Dynamic Data File. Provide the dynamic data file (.dyd) for the modeled data on either a compact disc or digital video disc. The file can be provided on the same disc with the raw test data in paragraph

3.3 (c).
