交流电动机调速系统在泵站中的应用

The Application of AC Induction-motor by Using Variable-speed System to the Pump Station

本文针对大中型抽水泵站 ,叙述了高压三相异步电动机的变极调速方式和变频调速方式及控制方法 ,着重介绍了交 直 交电流源变频调速系统的结构原理和特点。

In this paper,we discussed the type of variable speed by change magnetic pole and by adjust frequency of high voltage three phase induction motor and the control method.The construction and characteristic of AC DC AC current source variable speed system is introduced.
