摘　　要：从配电网经济运行的角度 ,提出建立以降损效果最大为目标函数的模型 ,并将其分为单点补偿和多点补偿两种方式进行优化 ,确定配电网馈线电容器最佳安装位置和最佳补偿容量 .算例表明 ,对于 10kV带分支的长配电线路 ,经杆上无功优化补偿后 ,配电网的网损将进一步降低 ,经济效益可观 ,可推广采用 .Considering the economic operation of the distribution system of electric power, the paper presents an optimal model of reactive compensation on distribution feeders, aiming to minimize the power loss. The model falls into two categories, one with singly located capacitors, and the other with multiple capacitors. It determines the optimum size and location of shunt capacitors on a distribution feeder. The paper shows that the power loss of long distribution feeder with branches will be decreased further when reactive compensation on tower is put into use, and a considerable economic benefit can be produced.
