摘要
电压是电网电能的主要质量指标之一 .在电网中安装足够的无功补偿电容器 ,并优化无功补偿 ,使无功就地平衡 ,能减少无功功率长距离输送 ,充分利用设备的输变电能力 ,提高电网电能质量 ,降低电网网损 ;有利于提高供电企业经济效益和社会经济效益 .
Voltage is one of the important reference standards of quality of electric energy.Installing adequate capacitors of reactive compensation in networks and selecting optimum compensation to make local reactive power equlibrium,can reduce reactive power in distance transmission and make full use of transmitting and transforming capacity of equiments,and improve the quality of electric energy of power system and decrease the loss of networks.Thus it will benift the improvement of power supply enterprises and national economy .
