10kV配电线路无功补偿投切方式的比较分析

Comparative Analysis on Switching Mode of Reactive Power Compensation for 10kV Distribution Circuit

以10kV配电线路为研究背景,通过比较国内几种主流线路无功补偿投切方式,进行了投切方式对线路补偿的补偿容量和补偿位置影响的理论分析,并对投切方式对电压损失率与功率损失的影响进行了实例计算.结果表明,在10kV配电线路中,采取根据电压情况进行投切控制的方式更有利于提高功率因数、降低电压损失率.

In the background of 10 kV distribution lines,the influence of switching mode on the compensation capacity and compensation location in compensation in distribution circuit are theoretically analyzed along the comparative analysis of switching mode of reactive power compensation of several kinds of domestic mainstream line,and the influence of switching mode on loss of voltage and power is the calculated example.The results show that the mode of switching control by using the voltage is more advantage to rise the power factor and reduce voltage loss rate in the 10 kV distribution lines.
