浅析功率因数对工矿企业节能降耗的影响

在工矿企业用电中，用电户功率因数的高低，直接关系到电力网中线路上的功率损耗大小，如何有效地提高功率因数，降低线路损耗，是供配电系统中一个重要课题。围绕大方县水泥厂的供、配、用电各个环节存在的问题，探讨影响功率因数的主要因素及其提高功率因数的几种措施，并说明提高功率因数给企业带来的经济效益的效果。

Analysis on the energy- saving and consumption- reducing in industrial and mining enterprises influenced by power factor

The level of power factor of electronic power users, which are correlated to power loss in electronic power networks, the effectively enhanced power factor and power loss reductions, is a very important problem in power supply and distribution systems in the usage of electronic power in industrial and mining enterprises. Based on the problems of supply, distribution and usage of electronic power in Dafan Cement Plant, we discuss the main factors which fluences the power factor, and point out some methods to enhance power factor. Then we point out the economic benefits brought up by advanced power factor in enterprises.
