PART 3 EXECUTION

3.1 Model Validation Procedures and Personnel Qualifications

Submit Model Validation Test Procedures. The Contractor shall prepare for approval detailed field test procedures for model validation testing of the identified hydrogenerator systems. 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 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 the Generator Owner's Transmission Planner and/or Planning Coordinator. The contractor is responsible for researching all Generator Owner testing and model validation 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 of similar hydrogenerator systems, 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 hydrogenerator systems (i.e., generator, exciter, turbine-governor, PSS, etc.) the testing and the individual(s) who will be the knowledgeable technician or engineer. One qualified individual may perform one or more of the identified roles.
