在工矿企业中，异步电动机消耗的无功功率约占70%，因此造成工矿企业的功率因数低，线损大。本文就解决工矿企业的功率因数和线损等问题，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。
在工礦企業中，異步電動機消耗的無功功率約佔70%，因此造成工礦企業的功率因數低，線損大。本文就解決工礦企業的功率因數和線損等問題，對異步電動機運行時的無功變化進行瞭分析，給齣瞭異步電動機就地無功補償容量的計算方法。對異步電動機就地無功補償進行效益分析，說明異步電動機就地補償是經濟、簡單、可靠、高效的無功補償方法。

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.
