摘　　要：针对大型独立电力网络的特点,提出了一种新的网络拓扑结构在线分析法——扩展关联矩阵法.该方法融合了深度及广度优先搜索的优点,并可以进行局部搜索,提高了故障跟踪时的速度及准确度,给出了节点和支路的编码方法及扩展关联矩阵的形成方法.利用新方法,研究了系统的故障跟踪、故障处理方法及带有网络拓扑结构识别的实用简单潮流计算方法,为系统的故障恢复做好了充分的准备.Based on the characteristics of large isolated power network, a new method of online topology analysis method, expansion node-branch associated matrix is provided. It combines the merits of depth and width first search and local search can be done. It improves the speed and accuracy of fault tracing. The coding method of nodes and branches and formation method of expansion node-branch associated matrix are introduced. Using the new method, fault tracing and handling and the practical and simple algorithm of power flow calculation with the ability of topology identification are studied, which make ready for the fault restoration.
