首先对无功补偿的原理进行了分析

对自然功率因数和有功功率的确定方法进行了阐述;又对工矿企业常用的负荷异步电动机补偿容量的确定方法进行了归纳;最后通过实例对补偿后的节能效果及母线上的电压变化进行了分析计算

表明了异步电动机无功就地补偿的推广价值。

Abstract

Reactive power local compensation technology of asynchronous motor is analyzed by the author in this paper.The principle of reactive power compensation is analyzed and described firstly

the determination method of natural power factor and active power is introduced

then

the reactive power compensation capacity of load asynchronous motor in industry and enterprise is generalized.At last

through the practical example

the energy saving efficiency and the voltage variation on the bus after compensation are analyzed and calculated.The results show the promotion value of the reactive power local compensation technology of asynchronous motor.
