Modeling and simulation on AC variable speed system based on Simulink

为实现高动态响应的交流变频调速系统,在Simulink中建立基于两相静止坐标系下交流异步电动机数学模型模块和正弦波脉宽调制(Sinusoidal Pulse Width Modulation,SPWM)模块,进行交流变频调速系统的仿真,并在型号为Y160L—8的异步电动机上进行实测,将测试结果和仿真结果进行比较和分析,结果表明仿真模型基本符合实际情况.

To implement an AC variable frequency speed control system with high-dynamic response, the module for mathematical model of asynchronous electric motor under 2-phase static coordinates and Sinusoidal Pulse Width Modulation （SPWM） module are constructed by Simulink. The modules are used to simulate AC variable speed system and test on a Y160L-8 asynchronous electric motor. The results of test and simulation are compared and analyzed. It is shown that the simulation model is consistent with the actual situation basically.
