摘　　要：常规配电网极限线损率优化过程中主要注重误差的优化调整,极限线损率无法得到有效下降,影响配电网的高效运行。基于此,提出不平衡负荷下10/0.4 kV配电网变压器极限线损率优化方法。在不平衡负荷下检测配电网变压器的补偿电流,分析补偿电流产生的线损情况,判断线损率是否满足目标线损率要求。采用对比实验的方式,验证了所设计优化方法的极限线损率更低,符合配电网运行经济性的要求,具有较高的推广价值。In the process of optimizing the limit line loss rate of conventional distribution network,we mainly pay attention to the optimization and adjustment of errors,and the limit line loss rate cannot be effectively reduced,which affects the efficient operation of distribution network.Based on this,the optimization method of transformer limit line loss rate in 10/0.4 kV distribution network under unbalanced load is proposed.Detect the compensation current of distribution network transformer under unbalanced load,analyze the line loss caused by compensation current,and judge whether the line loss rate meets the target line loss rate.By means of comparative experiments,it is verified that the limit line loss rate of the designed optimization method is lower,which meets the requirements of distribution network operation economy and has high popularization value.
