摘　　要：针对传统中压配电系统网架结构研究中未将变电站与线路接线模式综合统一考虑的现象,该文重点结合三供一备接线模式,构建了基于三供一备接线模式的中压配电系统供电模型。在此基础上,对各种供电模型的主变供电能力指标和网络供电能力指标进行定量分析,得到各种供电模型的主变理论最大负载率以及主变实际负载率、主变实际出线条数、线路实际负载率等关键指标,从而有效指导配电网网架建设。Traditional research of medium voltage distribution network structure just focuses on the connection mode,which fails to consider the substations and connection mode.Based on three-supply-one-backup （TSOB） connection mode,power supply models of medium voltage distribution system were constructed.For each power supply model,the power supply capability of substation and network were analyzed.Some key factors of each power supply model were obtained,such as the maximum theoretical load rate of transformers,the actual load rate of transformers,the actual number of output feeder lines of transformers and the actual load rate of lines,which are able to serve as a guideline for distribution network structure construction.
