摘　　要：为保证智能配电网的高速可靠运行,研究了基于Prim智能算法的含分布式电源的智能配电网孤岛划分策略,该算法以求取连通图的最小生成树的方法,求解智能配电网的孤岛划分问题,在配电网发生故障时,及时制定最优的孤岛划分策略,有利于缩小电网故障恢复的停电区域范围和停电时间。文章将该算法应用于IEEE33节点含分布式电源的智能配电网系统中,验证了该智能算法的有效性。To ensure the high-speed and reliable operation of the intelligent distribution network, the paper studied is- land division strategies for the intelligent distribution network with distributed power supply based on the Prim intelli- gent algorithm. By means of the method of obtaining the minimum spanning tree of the connected graph, the algorithm solved the island division issues of the intelligent distribution network. When there was something wrong with the dis- tribution network, the algorithm could formulate timely the optimal island division strategy, which was propitious to re- duce the blackout area and outage time of the fault restoration of the power grid. In this paper, the algorithm was ap- plied to the intelligent distribution network with distributed power supply with IEEE33 nodes, and the effectiveness of the intelligent algorithm was verified.
