| 摘 要： | 为了深入研究多相变频调速系统,需要建立逆变器供电双三相异步电机系统的仿真模型。在双三相异步电机的动态数学模型基础上,利用MATLAB中的Simulink模块库和SimPowerSystems模块库构造逆变器与电机系统的仿真模型,属于信号流与电气流混合仿真,能够较好反映逆变器的电气特性。对模型分别施加正弦电压激励、SPWM电压激励,进行空载起动和突加负载等实验,仿真结果表明了模型的正确性和有效性。

| Abstract: | To study in depth the multiphase frequency speed regulation system,it is necessary to establish a simulation model for the dual 3-phase asynchronous motor system driven by an inverter.On the basis of the dynamic mathematical model of the dual 3-phase asynchronous motor,MATLAB Simulink and SimPowerSystem are used to construct a simulation model of the inverter and motor system （mixed simulation of signal stream and electrical stream）for a good reflection of the electrical characteristics of the converter. Sine voltage excitation and SPWM voltage excitation are separately imposed on the model for tests on zero-load start and abrupt load. The results of the test verify the correctness and effectiveness of the model. |
