配电网络重构的改进支路交换法

根据配电系统中存在大量独立拓扑调整的特点，提出一次可以实施多个独立拓扑调整的配网重构方法，并通过节点流过的负荷电流值与理想转移负荷之间的距离确定打开的分段开关，进一步提高了处理效率，当降损效率小于给定值时不再进行网络重构；避免了无实际意义的拓扑调整。该算法考虑并非所有配网支路上都安装开关，更符合实际情况。给出的算例表明该方法是有效的。

A REFINED BRANCH-EXCHANGE ALGORITHM FOR DISTRIBUTION NETWORKS RECONFIGURATION

A distribution networks reconfiguration algorithm which can achieve several independent topology restructure in a search is proposed. For these tie switches whose ideal efficiency of reconfiguration exceed specified value, the optimum topology restructure are determined by calculating the distance from the ideal transferred load to the loads transferred and the lowest distance is considered the best for loss reduction. Topology restructure is discarded when the efficiency of reconfiguration is less than specified value, thus, worthless topology restructure for practical purpose can be avoided. Not all branches can being exchanged is considered. Results show that the proposed algorithm is feasible.
