摘　　要：为适应新型电力系统建设需求,提出一种适合国情的雪花格式网架结构。首先,总结国内外典型城市中压配电网结构的特征与优缺点;然后,结合天津已有网架结构,提出雪花格式网架结构及其构建方法;其次,分析测算雪花网结构的负荷转移能力、可靠性与效率效益水平;最后,从结构形式、适合场景等方面给出雪花网结构与花瓣结构等的综合对比情况。结果表明,雪花格式网架结构具有一定综合比较优势,可为中压配电网远景目标网架规划提供指导。In response to the construction requirements of novel power systems,a snow-shaped grid structure suitable for conditions in China is proposed.First,the characteristics and advantages/disadvantages of typical urban medium-voltage distribution network structures at home and abroad are summarized.Second,based on the existing grid structure in Tianjin,the snow-shaped grid structure and its construction method are put forward.Third,a detailed analysis is con-ducted to estimate the load transfer capacity,reliability,efficiency and benefits of the snow-shaped grid structure.Fi-nally,from the aspects such as structural form and suitable scenarios,a comprehensive comparison between the snow-shaped structure and other structures including the petal-shaped structure is performed.Results indicate that the snow-shaped grid structure exhibits certain overall comparative advantages,providing guidance for the grid planning of medi-um-voltage distribution networks in the future.
