摘要配网的辐射形和连通性,是配网重构的约束条件。配网闭环设计、开环运行,如果合上联络开关,则构成一个小环,必须在此环中打开一个分段开关,使配网保持辐射形。因此一个联络开关决定一个环网,这是基于环网的编码方法,本文基于环网编码,讨论了判断网络辐射形的规则与流程。定义了表达节点与节点、节点与支路关系的连通矩阵。根据连通矩阵的对角元素,判断孤点;通过连通矩阵,由末端节点追溯到首端节点是否为电源点,判断是否为孤岛。最后用两个算例证明本文提出方法的有效性。

Abstract：The radial and connectivity of distribution network are the constraint conditions in distribution networks reconfiguration. Distribution network is designed in closed loop and operated in open loop. If contact switch closed, there will be a small ring. At the time, there must be a section switch opened in the ring to make the distribution network keeping radial. Therefore, a contact switch decides a ring network, it’s the encoding method based on ring network. And based on it, this paper discusses the rules and procedures of judging radial of network and defines a connection matrix which stands for the relationship of node to node, node to branch. Judging the diagonal element of the connection matrix is or not will determine the existence of acnode. Judging the nodes from the end node to the head node of the connection matrix is source point or not will determine the existence of island. In the end, two examples validate the efficacy of the method proposed above.

Key words： Distribution networks reconfiguration radial connectivity island
