摘　　要：抽水蓄能电站采用交流励磁可变速电机具有提高机组工况运行的效率和转换时间等优点,解决了过去通过改变电机的极对数所带来的技术问题。在Matlab/Simulink仿真软件平台上搭建水泵水轮机、交流励磁电机的仿真模型,并采用定子磁场定向矢量控制策略对电机模型进行仿真验证。仿真结果表明应用矢量控制策略可以使抽水蓄能双馈电机的有功功率和无功功率解耦并快速响应。The adjustable speed unit with AC excitation which has the advantages of improving condition operation efficiency and conversion time has been used in pumped storage power station to solve the technical trouble resulted from changing the pole-pairs. The simulation models of pump turbine and AC exciting generator are established in Matlab/Simulink to prove the stator flux-oriented vector strategy. The results show that the strategy of vector control can realize the active power and reactive power decoupling control and respond quickly.
