[Abstract]:Pumped-storage power station plays an important role in power system, such as cutting peak and filling valley, frequency modulation and phase modulation, etc. The accidents of hydraulic machinery of hydropower station often occur in its transition process, in order to facilitate the simulation and analysis of the transition process, It has important research and application value to establish the mathematical model of its regulating system and develop the simulation platform. In view of the difficulties existing in the modeling of regulating system of large pumped storage unit, the model of long water diversion system is established by using piecewise modeling principle, and the model of pump turbine is established by using RBF neural network. The experiment analysis of no-load frequency disturbance and load increase and decrease are also carried out. The simulation results show that the model reflects the actual unit characteristics to some extent. Based on the Lab Windows/CVI virtual instrument software, the communication between the simulation platform and Matlab is realized by using Active X interactive technology, and the corresponding simulation platform of the model is developed. It provides a friendly man-machine interactive simulation environment for researchers and field operators and maintainers.
