摘　　要：本文提出了一种基于网络图论的逆变器供电感应电动机调速系统通用仿真算法。感应电动机采用定子量保留在ABC系统、转子量折算到αβO系统的混合模型，既消除了电机电感矩阵中的时变量，又可与逆变器电路直接结合。采用网络图论分析方法，把包括逆变器和电机在内的整个调速系统生电路作为一个拓扑图来处理．得到的仿真模型能对逆变器和电机两部分电路同时求解。该模型能对任何电路结构形式、任意开关模式的逆变器供电感应电动机调速系统进行分析。仿真结果验证了该算法的正确性。This paper presents a general simulation algorithm based on graph theory for the inverter-fed induction motor drive systems. The hybrid model,which preserves stator variables in phase quantities and transforms rotor variables to theop reference frame,is developed for the induction motor. This machine model will not only eliminate the time-varying terms of the inductance matrix,but also can be directly interfaced with the inverter circuit. By treating the completed main circuit of the drive system as a graph,the derived formulation can solve the overall inverter circuit and machine equations simultane ously,and has the ability to analyze any induction motor drive circuit configurations with arbitrary conduction patterns. This algorithm is verfied by simulation results.
