摘　　要：分析了中压配网的现状和存在的问题,综合考虑中压配网的多种指标因素(如供电能力、线损、可靠性、经济性等),建立了中压配网电压等级优化的层次分析模型。最后,针对某地区3种具有代表性的负荷密度区采用AHP法进行了仿真计算分析,得出该地区主城区适合采用220/110/20/0.4kV和220/20/0.4kV 2种电压等级序列,而农村适合采用220/110/20/0.4 kV电压等级序列的结论。This paper analyzes the status and existing problems of middle voltage distribution networks.Considering comprehensively several factors of the middle voltage grade distribution networks such as power supply capacity,energy loss on the line,reliability,economy and so on,the model of analytic hierarchy process of the middle voltage distribution networks is proposed in the paper.Finally,the results of simulating calculation of three representative power load density regions demonstrate the efficiency of the proposed model,and show that two kinds of voltage grade sequences of 220/110/20/0.4 kV and 220/20/0.4 kV are suitable for urban area of the three regions,while the voltage grade sequence of 220/110/20/0.4 kV is suitable for the countryside of the three regions.
