摘要

针对含分布式电源配电网发生故障后的供电恢复问题，提出了一种基于冒泡算法的孤岛划分方法。首先，将配电网转化为无向连接图；然后，通过给出无向连接图各节点的权值，按照冒泡算法搜索得到满足条件的节点集合；最后，将集合之外负荷节点的开关切除。仿真结果表明：冒泡算法可以最大程度上保持配电系统完整性，故障切除后只需要投切负荷开关就能恢复系统供电；所提出的孤岛划分方法不但适用于辐射形网络，还可以应用到环形网络。

Abstract

This paper puts forward a island division method based on the bubble algorithm to restore the power supply of distribution network with distributed generation (DG). Firstly, the distribution network is transformed into an undirected connection diagram. Then, the weights of all nodes in distribution network are given, and the set of nodes satisfying the conditions is searched by using the bubble algorithm. Finally, the load switches of the nodes outside the set are cut off. The simulation results show that the bubble algorithm can maintain the integrity of the distribution network to the greatest extent, and only the load switch is used to restore the power supply after fault removal. Moreover, the proposed island division method is applicable not only to the radial network but also to the ring network.
