摘　　要：为解决现有针对农村电网末端低电压所设计的串联电压补偿装置经济性较差问题,设计了一种基于串联电压补偿控制的低电压治理方法。在考虑了负荷电压的静态特性的影响下,将线路有功损耗和各节点平均电压偏差两指标进行归一化加权作为目标函数,提出了选取补偿装置的位置和容量优化配置方法。选取某地区实际电网末端低电压线路进行仿真测试,结果表明该方法可有效解决农网末端的低电压问题。In order to solve the problem of poor economy of series voltage compensation device designed for low voltage at the end of rural power grid,a low voltage control method based on series voltage compensation control is designed.Considering the influence of static characteristics of load voltage,the two indicators of line active power loss and average voltage deviation of each node are normalized and weighted as the objective function,and the method for selecting the location and capacity of compensation devices is proposed.The low voltage line at the end of an actual power grid is selected for simulation test,and the test results show that the method can effectively solve the low voltage problem at the end of rural power grid.
