摘    要:针对传统网络拓扑方法多次重复搜索路径、效率低、速度慢的缺点,文章提出一种基于广度优先的快速网络拓扑方法.该方法将电力设备抽象为节点和支路,使拓扑过程不受网络接线形式和结构的约束,对输电网和配电网可统一进行拓扑分析,增强了算法的通用性.同时,该方法利用节点-支路邻接表,加快了拓扑速度.开关状态改变时,通过修改节点一支路邻接表,可进行局部重新拓扑,提高了拓扑灵活性.实际应用中,该方法可以满足系统对各电压等级网络拓扑的要求.

关 键 词:网络拓扑  广度优先搜索  节点-支路邻接表  局部网络拓扑

Abstract:A fast tracking method for network topology based on breadth-first search is presented, which effectively surmount the defect of repeatedly searching the branch in traditional topology. In the presented method the power equipments are abstracted as nodes and branches, so for topology process the constraint from the connection scheme and the structure of the power network can be avoided and the topological analysis both for transmission network and distribution network can be carried out consistently. Moreover, using the adjacency list of node-branch in this method, the topology is accelerated. When the state of switches changes, only local network topology is necessary, so the flexibility of topology is improved. The presented method can meet the topological needs of networks in various voltage classes.
Keywords:Network topology  Breadth-first search  Adjacency list of nodes and branches  Local network topology
