感应电机软起动新技术

A New Technique for Induction Motor Soft-starting

文中提出的控制策略用于感应电机的启动过程中。通过控制晶闸管组成的三相交流调压电路,使其输出电压和频率的比率接近常数,从而使感应电机启动过程中保持低电流的同时可以产生较大转矩。还通过仿真,同传统软起动方法的性能上做了比较分析。

This paper introduces a control strategy which can be used in the induction moter's starting process. If we control AC thyristor-controllers with the proposed technique,we can get higher torque and less starting current.The proposed technique is simulated and comparisons are done with the traditional soft-starter. Results show the proposed technique is applicable in many conditions.
