摘　　要：就多环配电网以降损为目的重构问题 ,提出了分步最优化的重构算法。算法以网损降估计方法为基础 ,分步优化 ,每步将一个开环点移至相邻支路 ,使网损降最大 ,最终达到重构后网损最少。重构算例表明 ,分布最优化重构算法算式简明 ,计算速度快 ,重构结果最优。A multiple-step optimization algorithm for multiloo p distribution network reconfiguration to minimize network losses is presented i n this paper.Based on the losses' estimate method, a broken point is moved to th e next branch in every optimal processing in order to maximize the loss reductio n, and at last reach an optimal state operation with minimal losses after the re configuration.Test results show that the algorithm is of simplified formula, fas t calculation speed and optimal results
