摘　　要：针对农网线路供电半径较长、负荷分散、线路损耗较大的特点,探讨安装并联电容器进行无功补偿对提高农网长线路的电压及功率因数质量的作用。通过对典型的农网长线路进行现状分析,确定无功补偿的方式及补偿容量,对线路进行无功补偿。对比补偿前后线路功率因数及末端电压的变化,结果显示在农网线路并联电容器进行适当的无功补偿,能有效提升线路末端的电压质量及功率因数,对改善10kV农网线路供电质量具有重要意义。Considering characteristics of long supply radius, load scattered and large line loss in rural power grid, the mstallaUon ot shunt capacitor for reactive power compensation to improve the voltage and power factor of long line is discussed. The type and capacity of the reactive power compensation is determined by analyzing typical long line in rural power grid. By comparing the power factor and terminal voltage of the line before and after compensation, it is found that proper reactive power compensation for the line of rural power grid by shunt capacitor can effectively improve the terminal voltage quality and power factor, which has important significance to improve the power supply quality of 10 kV line of rural power grid.
