Research on Optimization of Modeling and Simulation of Yangjiang 400MW Pumped Storage Unit and Its Governor
In this paper,an optimization method combining unit characteristic curve,field test and simulation fitting is proposed based on the modeling analysis of Yangjiang 400MW pump turbine,generator motor and governor.Firstly the steady-state model under different heads and full load sections of the unit was established according to the operation characteristic curves of the turbine and the pump.Then,the turbine dynamic model was established through the turbine characteristic parameter Tw obtained through the field test.Thirdly,the characteristic parameter of the generator Ta were obtained through the field load dump test,and the model was optimized while the governor model was refined considering the servo valve,the main pressure distribution valve and other links.Finally,the models were verified which shown the accuracy of the modeling method.
