摘要: 利用无功补偿给三相异步电动机并联电容器以提高其总功率因数是目前提高电动机运行功率因数的普遍做法。通过对水利泵站高压异步电动机在不同负荷率下运行特性的分析,提出了三相高压异步电动机并联电容器容量选择的新方法,由此配置的电动机无功补偿容量在实际运行中获得了良好的补偿效果。

Abstract: Using the capacitors connected parallel with threephase asynchronous motor to realize reactive power compensation for raising the total power factor is the widelyused method for increasing the motor operation power factor. Based on the analysis of operation characteristics of highvoltage asynchronous motor in pump station of water conservation project with different load factor, a new method to select the capacity of the capacitor parallel connected with three phase highvoltage asynchronous motor was put forward. Favorable compensation effect of the motor reactive compensation capacity configured by this method was obtained in practical operation.
