Combustion turbine dynamic model validation from tests

Studies have been conducted on the Alaskan Railbelt System to examine the hydrothermal power system response after the hydroelectric power units at Bradley Lake are installed. The models and data for the generating units for the initial studies were not complete. Typical models were used, but their response appeared to be faster than judged by operating experience. A testing program was felt to be necessary so that accurate models could be obtained for the dynamic simulation studies. The testing method used for the combustion turbine governors, the models derived from tests, and comparison of those models with typical models are discussed. Simulation results revealed that the typical models were more optimistic.>
