摘　　要：本文为了研究同步电动机群单机异步起动问题 ,提出了不同的起动电机与运行电机仿真模型 ,并对输电线路阻抗加以考虑 ,同时根据起动电机在起动过程的不同阶段采用合理的转矩计算公式。数学模型均采用精确的 Park方程描述 ,并用 Matlab语言对其进行仿真 ,得出结果与实际吻合。This paper presents a different simulation model of synchronous motor for runnin g and starting motor when one synchronous motor had been asynchronous direct on line starting.Account to different starting stage of starting motor,correspondi ng electromagnetic torque function is used.Line impedance has been take into con sideration.The simulation model of synchronous motors is developed from the Park 's equation.The simulation program is written in Matlab language.Simulation resu lt presents the transient performance of the condition studied and it is quite s ame with the result of the real experiment.
