电力电子电机系统的计算机仿真

针对复杂的电力电子电机系统通常具有多个非线性环节，且实验模拟测试困难费用昂贵等问题，采用仿真方法，通过分析复杂电力电子电机系统的结构，并根据其结构特点，研究了其各组成部分的建模与仿真方法，提出了根据各子系统复杂程度单独建模、再从系统角度把电路仿真和系统仿真结合起来联合仿真的仿真研究方法。依据上述建模与仿真方法，对三电平逆变器驱动的长定子直线同步电机控制系统进行了建模与仿真研究，并采用Visual C＋＋编制了其仿真程序，验证了所建立的模型和所采用的仿真方法正确性。

Computer simulation of power electronic and electric machine system

In view of the fact that the complicated power electronic and electric machine system has multiple nonlineerand simulating tests are difficult and costly,the paper analyzes the configuration of the complicated power electronic and electric machine system,studies the model and simulation methods of each section and according to its section complexity,proposes the method of the modeling and simulation method of modeling separately and simulating connectedly to combine the circuit simulation method with the system simulation method.With the above modeling and simulation method,the paper programs a long-stator linear synchronous motor system with three inverter controlled with Visual C programming software and validates the correctness of the modeling and simulation method.
