摘　　要：用电企业的功率因数控制对企业自身和整个供电电网的电能利用效率具有重要作用。用电企业按照供电公司的要求控制好功率因数不但能够提高整个电网的供电效率和供电质量,还可以减少自身的用电费用支出。本文结合青海省供电公司关于功率因数相关的电费政策,再结合实际用电企业功率控制的实际情况,详细介绍了高电耗电解铝企业的功率因数控制原则和方法。Controlling power factor of the enterprise plays an important role for the enterprise itseff and energy using elticiency of the whole power grid. The power consuming enterprises control power factor based on the requirements of power supply companies, can not only improve the efficiency and quality of power supply of the whole power grid, but also reduce their electricity charge. In this paper, based on the relevant electricity charge policy about power factor in Qinghai Power Supply Company, control principles and method for power factor in high power consumption smelters are detailed introduced com- bining with the actual situation of power factor controlling.
