摘　　要：配电网中的功率损耗主要来自变压器及其供电线路,不同负荷功率情况下,变压器的运行电压对配电网中的损耗有重要影响。因此,改变配电网供电电压,可以改变功率传输过程中在变压器和供电线路上产生的功率损耗。针对电力系统在经济供电半径下,负荷高峰阶段和负荷低谷阶段两种不同情况,分析了如何通过合理调整变压器分接头来减少在变压器及供电线路上的损耗。The power loss mainly comes from power transfomier and power supply line,and with different load for transformer,the operating voltage plays an important influence for the loss of power distribution network.So the power loss of transformer and power lines can be changed by altering distribution network＇s voltage in the process of power transmission.In this paper,according to economic power supply radius,considering the two operations of peak load stage and low load stage,how to rationally adjust the transformer points is analyzed to reduce the power loss of transformer and power line.
