摘　　要：为了解决配电网最小网损控制能力差、网损指数高的问题,提出一种新的基于网络重的网损控制方法。该方法通过查找技术网损以及管理网损,设定系统拓扑结构图,集中检测,查找异常数据,通过对变压器进行电流分配以及支路电流分布计算,确定网损量,将配电网中的网线损失分为变压器损失以及线路损失俩部分,对无用功进行无功就地补偿处理,集中安装变电电容器,配电线路按照分散式安装进行操作。为验证方法效果,设定对比实验,结果表明,基于网络重构的配电网最小网损控制方法能够有效降低配电网网损。In order to solve the problem of poor minimum loss control ability and high loss index in distribution network,a new loss control method based on network weight is proposed.This method determines the network loss by searching the technical network loss and managing the network loss,setting the system topological structure diagram,centralized detection and abnormal data,calculating the current distribution of transformer and branch current distribution,dividing the network loss into two parts:transformer loss and line loss,compensating reactive power locally and installing transformer centrally.Electric capacitors and distribution lines are operated according to decentralized installation.In order to verify the effectiveness of the method,a comparative experiment is set up.The results show that the minimum loss control method based on network reconfiguration can effectively reduce the distribution network loss.
