摘　　要：针对现有配电网环网接线方式选取的现状,提出了环网接线方式综合优选方法。通过环网接线方式和综合评价指标建模,结合广东某地区配电网规划进行算例分析,对2-1、3-1主备接线方式和3供1备方式3种环网接线方式在相同负荷量下的线路成本、运行损耗、故障停电损失3个评价指标进行考察并折合为费用作综合比较,给出了不同负荷密度下配电网环网接线方式优选的建议。In accordance with current status of selection of loop connection mode for distribution networks, the paper proposes a comprehensive optimal selection method. By loop connection mode and modeling of comprehensive assessment index, the paper makes calculation analysis of distribution networks planning in some place in Guangdong. Line cost, operating loss and loss of accidental blackout of 2-1, 3-1 main and auxiliary connection modes and three-supply plus one auxiliary mode in the same load capacity are reviewed and comprehensively compared in terms of cost. Selections of loop connection of loop connection mode for distribution networks in different load densities are given.
