高压同步电动机异步全压启动是一种简单经济的启动方法。基于同步电动机的Park方程数学模型，建立了标幺值和有名值混合形式下同步电动机的状态方程组。利用M atlab编写了异步全压启动程序，并采用四阶龙格库塔法求解微分方程组，克服了Sim ulink建模存在的过程复杂、计算精度低、仿真时间长等缺点。此外，案例分析的仿真曲线表明了本文方法的正确有效性。

The asynchronous direct-on-line starting of the high voltage synchronous motor is the simplest and most economical starting method .This paper has established the state equa-tions of synchronous motor based on Park model ,w hich mix per-unit value with actual val-ue .Then ,using Matlab to write asynchronous direct-on-line starting program and solve dif-ferential equations by Four Order Runge Kutta ,which overcoming the shortcomings of low accuracy ,long simulation time and complex modeling by using Simulink .Simulation curves of the case indicate this method is correct and effective .
