Based on the analysis of new goals and new trends in current power system simulation, this paper introduces the electrical module of cascade hydropower station and its implementation in the simulation support system. The mathematical model under normal operation and abnormal operation mode The simulation results and analysis of the loss of magnetism model in cascade hydropower station system are presented. The whole system model can accurately simulate the operation status of the cascade hydropower station. The model has been used in the cascade hydropower station simulation training system, and its accuracy and real-time performance meet the requirements.
