This paper establishes the model of variable frequency speed-regulating system based on PSCAD for power plant auxiliary and its load model, and completes the logic interfacing with the BPA simulation platform.The joint simulation system of the electromechanical transient and electromagnetic transient is realized, which is used for the analysis and research of the influence of power grid fault on power plant system.By the simulated analysis of the single phase fault and three phase fault of power plant outgoing line, the accuracy and engineering application value of the simulation model are verified.
