Modelling and Computer Simulation of SCR Controlled Low-Speed Linear Induction Motor Based on instantaneous Symmetrical Components Theory

本文提出考虑了直线电机边缘效应的低速直线感应电机系统的瞬态对称分量法模型。模型可用于分析晶闸管控制的直线感应电机系统在不同运行模式下的动态过程。文中对直线电机调速系统的起动和反接制动过程进行了计算机仿真,并做了实验验证。

The model of low-speed linear induction motor based on instantaneous symmetrical components theory is presented in this paper. End effect of LIM is considered in the model.This model can be used for analysis of the transient performance of SCR-controlled LIM system indifferent operational modes. The digital simulation is given for the starting and braking transients of the system. The simulation results are verified by experiment.
