对异步电动机运行时的无功变化进行了分析

给出了异步电动机就地无功补偿容量的计算方法。对异步电动机就地无功补偿进行效益分析

说明异步电动机就地补偿是经济、简单、可靠、高效的无功补偿方法。

Abstract

In the industrial and mining enterprises

the consumed reactive power of asynchronous motor is about 70%

which causes low power factor and larger line loss. In this paper

the reactive power variation during operation of asynchronous motor is analyzed in order to solve such problem of the enterprise as power factor and line loss and the method of calculating local reactive power compensation capacity of the asynchronous motor is given. It is shown by the efficiency analysis of the local reactive power compensation of asynchronous motor that the local compensation of asynchronous motor is a economic

simple

reliable and high efficient reactive power compensation method.
