THIPWM逆变器供电至异步电动机时电机动态性能的仿真研究

Dynamic Performance Simulation of THIPWM Inverter Fed Induction Motor

利用坐标变换理论,建立了异步电动机的数学模型,探讨了THIPWM波形的生成原理,最后通过MATLAB对THIPWM交流调速方案供电至异步电动机的稳态性能以及动态性能进行了仿真,讨论了几个电机参数的取值对异步电动机的性能影响。

With the theory of transform of coordinate, the simulating model of induction motor fed by the Third Harmonic Interject Pulse Width Modulation (THIPWM) inverter is set up. Along with the model, the dynamic performance of the system is simulated. Compared with the SPWM pattern the results are given and at last we also give the results that a few of parameters' changing will lead to the performance of induction motor.
