摘要
在电力系统的供电过程中,电力网中功率损耗和电能损耗、供电线路的电压损失和电压波动,都直接影响到用户端的功率因数高低,也直接影响到节约电能和整个供电区域的供电质量。电力系统的无功补偿是提高系统运行电压,减小网损,提高系统稳定水平的有效手段。本文介绍了影响电网功率因数的主要原因以及输配电网中低压无功补偿的原理及方法,以达到改善功率因数、调整电压及补偿参数等作用。
During the power supply of system,all of the power loss and power consumption,voltage loss and voltage fluctuation in power line directly affect the power factor of clients,also directly affect power saving and the quality of regional power supply.Reactive power compensation of the power system is an effective mean to improve the system operating voltage,decrease network loss,and improve the system stability.This article introduces main reasons influencing power grid factor and principle and method of low-voltage reactive-power compensation in power supply and distribution network to improve the power factor,adjust voltage and compensation parameters,etc.
