Abstract：Pumped storage power stations play an important role in peak load shifting and frequency & phase modulation in power system. Accidents in hydraulic machinery of the hydropower plant often occur in the transition process. For the convenience of transition process simulation and analysis, the establishment of mathematical model of regulating system and development of simulation platform are essential or have important value for research and application. Aiming at the difficulty of modeling of re-gulating system of large pumped storage units, piecewise modeling method is proposed for the mathematical model of long diversion system and RBF neural network modeling method is proposed for pump turbine respectively in this paper, and frequency disturbance transient under no-load condition and the increase or decrease of load are simulated. Simulation results indicate that the established models reflect the realistic characteristics of the plant to some extent. The simulation platform of the established models is developed based on LabWindows/CVI virtual instrument software, and the ActiveX interactive technology is applied for the communication between simulation platform and Matlab, which provides an ideal environment for researchers and local operators and maintainers to carry out simulation experiments, as well as providing reference for the development of similar simulation platform.
