摘　　要：配电网节点众多,拓扑结构复杂。在实现配电自动化功能时,需要知道各个节点在配电网中的位置以及节点之间的相互联结关系,网络的拓扑结构模型不仅要描述出各节点的邻接关系,而且还要描述出各节点间的路径关系。文章根据配电网拓扑结构的特点,提出了将配电网的拓扑结构等效解耦为边相接和边不相接的两种方法,得到若干个数目和负荷节点数目相同的单树枝。两种等效解耦的结果分别反映了配电网节点的联结关系和网络的拓扑分层。Distribution network possesses many nodes and its topology is complex. In the implementation of distribution automation (DA), it needs to know the position of each node and the interconnection among the nodes. In topological model of distribution network not only the adjacency among the nodes should be described, but also the path among the nodes. On the basis of the features of the topological structure of distribution network, two equivalent decoupling methods are presented, i.e., the border connected method and the border disconnected method, thus, the single branches of which number is equal to that of the nodes are obtained. The decoupling results by the two methods reflect the connection of the nodes in distribution network and the topological layers of distribution network.
