摘　　要：变电站的选择对电网结构、电能质量以及下级输电系统都有重要的影响,传统的变电站选址模型多从经济性角度考虑,这种选址方法缺乏全面性且易出现模型多解现象。首先,利用GIS系统为变电站的选址模型提供相应的边界已知条件,从而得到符合边界条件的变电站建址;然后,利用变电站选址综合评价模型,解决GIS系统中变电站选址的多解问题,通过变权权重划分模型,综合评价出变电站的最佳选址位置;最后,利用实际算例分析验证模型的有效性。The selection of substation has an important impact on the power grid structure,power quality and lower level transmission system.Traditional substation location models are mostly considered from an economic perspective.This location method lacks comprehensiveness and is prone to multiple solutions.Firstly,GIS system is used to provide the corresponding boundary conditions for the substation location model,so as to obtain the substation location that meets the boundary conditions.Then,using the comprehensive evaluation model of substation location,the multi solution problem of substation location in GIS system is solved,and the optimal location of substation location is comprehensively evaluated through the variable weight division model.Finally,the validity of the model is verified by an example.
