交流异步电动机固态软启动器技术及仿真研究

Technology and Simulation Study of Solid Soft Starter for AC Asynchronous Motor

讨论交流异步电动机固态软启动器采用的控制方式,对目前比较先进的几种控制方式作了较为详细的论述,分析各种控制方式的适用场合。利用Matlab搭建软启动的仿真模型,以电流斜坡控制方式为控制策略,分析不同类型负载下的启动效果,为正确选用软启动控制策略提供有效依据。

The control modes of soft starter for AC asynchronous motor are discussed, several advanced control modes are discussed in detial, and the applicable situation scope of various control modes is analyzed. A simulation model for soft start is established by using Matlab, and start effects under different loads is analyzed by using slope current control as a control strategy to provide effective basis for selection of soft start control strategy.
