异步电动机软起动器控制方式及仿真研究

摘要

Soft starter technology is advantageous to the improvement and the control of the start-up procedure of induction motor. Some main control modes of the soft starter for induction motor were discussed, and the suitable occasion was analyzed. The current slope control mode was established on the basis of power system block set in MATLAB / Simulink. The start-up effects in different types of load were analyzed. The effective basis for choosing appropriate soft start control strategy is provided.%软起动技术有利于改善和控制异步电机的起动过程。讨论了交流异步电动机软起动器的几种主要控制方式，分析了各种控制方式的适用场合。利用MATLAB搭建软起动的仿真模型，以电流斜坡控制为控制策略，分析不同类型负载下的起动效果，为正确选用合适的软起动控制策略提供有效依据。
