摘要
本文研究了一种由高性能变频器控制的异步电机控制系统。首先介绍了变频器在异步电机控制中的应用。接下来研究了滑差补偿对电机转速以及电机负载特性的影响,同时还研究了变频器的功率因数补偿。通过滑差补偿使不同负载状态下的电机转速都较为恒定,从而达到优化控制的目的。
This paper discusses control system that consists of high performance frequency converter and induction motor. In the beginning fi＇equency converter control of induction motor is explained. Furthermore, the measurements of slip compensation parameter change irrfluence on motor speed and motor load dependence are performed, as well as measurements of power factor correction attained by frequency converter. It is possible to compensate sfip completely, so that motor speed is constant, regardless of motor load, which provides optimal control.
