摘　　要：通过对300MVA脉冲发电机组的机械结构和电气特性的分析,利用现有的试验数据和铭牌数据对整个机组的运行参数进行了等效计算,建立了基于Simulink的大功率异步电机双闭环矢量控制模型并进行了仿真分析。通过调节转速环和电流环的比例积分(PI)参数改善电流、转矩波形质量。仿真结果表明,该调速系统具有较好的动、静态性能,能够很好地满足机组的启动及运行要求。The entire operating parameters of the 300MVA motor generator were equivalently calculated using the existing test data and nameplate data and its equivalent model was established by analyzing its mechanical structures and electrical characteristics. Based on Simulink, the vector control model of high power induction motor with double closed loop was established and simulated, the quality of current and torque waveform can be improved by adjusting the Proportional-Integral parameters of speed ring and current ring. The simulation results show that the system has good dynamic and static performance and can meet the requirements of starting and running of the motor generator.
