摘　　要：随着国有煤矿用电量的不断增加,电费已经是煤矿整个经营成本的重要组成部分之一。据统计,电费成本已占国有煤矿整个经营成本的前三位。如何节约电能、降低电费,最大限度地减少电能损耗和功率损耗,已成为煤矿企业中一个重要课题。文章简要探讨了功率因数与节约电能的关系,叙述了几种提高电力系统功率因数及低压无功补偿的方法。With the constant increase of electricity in national coal mines,the electricity cost has become one of the most important part of the whole operation cost.It is estimated that electricity cost has been the third of the whole operation cost.How to save electricity energy,low electricity cost,reduce electricity loss and power loss to the largest limitation,has become an important task in the coal mines.This article simply explores relationship between power factor and saving electricity energy,describes several ways of improving electricity system power factor and low tension compensation without power.
