摘要

在主供电网络出现故障时，DG孤岛运行可以有效地提高用户的可靠性。本文基于最小生成树的概念建立了孤岛权模型。然后在故障隔离时，通过最小树生成无故障区域，形成径向配电网。同时，根据尽可能多的恢复负荷的目标，通过动态规划对树进行分离。最后以118个节点的IEEE配电系统为例进行孤岛分离。结果表明，该方法是合理有效的，其可靠性直接关系到DG的输出。

Distribution network island separation with distributed generation (DG) based on dynamic planning

DG islanding operation can efficiently improve the reliability of customers when main power supply network has a fault. This paper installs the weight model of islanding based on the concept of minimum spanning tree. Then the non-fault area is generated by the minimum tree to form a radial distribution network when the fault is isolated. In the mean time, the tree can be separated by dynamic planning according to the goal of the restoring load as much as possible. Finally, it's to use IEEE distribution system with 118 nodes as an example to separate the island. The result shows that the method is reasonable and valid and the reliability is directly related to the output of DG.
