为应对配电网重构中频繁改变开关状态并多次进行潮流计算的寻优效率低下、无法全局寻优等缺陷，以降低配电网运行网损为目标，提出了基于网损灵敏度及禁忌搜索的重构新方法。该方法通过定义网损相对开关状态的网损灵敏度指标，按启发式规则依次开闭开关并进行潮流计算可得到网损灵敏度开关排序表，以此为基础为禁忌搜索算法构造合理搜索邻域，在利用禁忌搜索全局寻优后最终可得到网路最佳重构方案且寻优时间满足应用需求，最后通过算例验证了该方法的有效性。

In order to deal with the poor efficiency and locally optimal solutions in reconfiguration of distribution network , which is caused by frequently state change of switches and multiple call of power flow calculations , a new reconfiguration meth-od based on loss sensitivity and tabu search is proposed to reduce the active power loss .Firstly, the loss sensitivity index is defined by loss and switching state , and then a stored switch list can be obtained by power flow calculation and loss sensitivity index.On this basis, a reasonable search neighborhood is constructed by tabu search algorithm , the best available network reconfiguration scheme can be obtained after the global optimization by tabu search , and the optimization time can meet the ap-plication requirements .The results of calculation examples show that the proposed method is effective .
