就地无功补偿的综合效益分析

Comprehensive Benefit Analysis of Local Power Factor Compensation

通过就地无功补偿,提高工作现场的功率因数,可以减少供电线路的无功电流和总电流,继而可以降低线路损耗、变压器和开关配置的投资费用,并改善供电质量。文章就就地无功补偿的收益进行了综合分析,并以企业实例进行了比较计算。

Local power factor compensation can reduce transmission current, and then reduce transmission line＇s power loss and improve voltage quality. Furthermore, load capacity of transformer and switch can be downsized, and the investment can be decreased either. The paper analyzed the integrated benefit of local capacitor compensation, and compared the difference through real plant case.
