基于有向支路的配电网络拓扑分析方法

根据配电网矢量接线图的特点，把接线图中的连接点分为节点和结点两类，在此基础上提出了节点提取法。该方法首先把节点提取出来，将接线图分成小子图，然后以结点一图元支路关联矩阵为基础，通过原始邻接矩阵法得到有向支路．并用节点-有向支路关联矩阵来重新描述配电网络的拓扑结构。在这种拓扑结构的基础上，可以通过节点分析和有向支路分析来完成对整个网络的拓扑分析。应用表明，这种方法不但可以方便计算机处理具有不同设备类型和不同网络结构的配电网接线图，而且可以大大提高配电网拓扑分析的速度和效率。

TOPOLOGY ANALYSIS METHOD OF DISTRIBUTION NETWORK BASED ON VECTOR BRANCH

According to the vectorgraph characteristics of a distribution network, the joints in the vectorgraph are classified into two types: node and crunodes, and thereon an algorithm namely node-extraction method is proposed. In the algorithm, the nodes are first extracted out to cut the vectorgraph into many sub-graphs, and then a crunodes-element branch incidence matrix based on the sub-graphs is formed to obtain vector branches by the well-known algorithm of original incidence matrix. Based on the work above, the topology configuration of the distribution network can be re-described by the node-vector branch incidence matrix and the complete network topology analysis can be easily accomplished on the grounds of the node analysis and the vector branch analysis. The factual application shows that this method is capable of not only facilitating the computer processing graphics with different equipment modes and network configuration, but also greatly improving the speed and efficiency of topology analysis of distribution network.
