摘　　要：国内配电网一般采用闭环设计,开环运行的供电方式,城市10 k V配电网络已形成了"手拉手"的环行供电网络,通过解合环操作可减少停电时间,供电可靠性也得到一定的提高,但依然存在短时停电问题,随着我国社会经济的快速发展,负荷需求增长迅速,尤其是重要敏感用户对供电可靠性的要求越来越高,迫切需要进一步提供配网供电可靠性。文中对10k V配电网闭环运行模式进行研究分析,并提出一种可行的网架结构优化方案。The distribution grids in China are commonly in the way of closed-loop design and opened-loop operation. The distribution grids in cities has formed a ＂hand-in-hand＂ structure. Through opened/closed loop operation, power supply reliability has been improved. However, customers are still likely to suffer short-time outages. Currently, improving power supply reliability becomes an urgent demand. This paper proposes a solution for grid structure optimization based on the analysis of closed-loop operation mood of 10 k V feeder.
