摘要
电力网络作为城市生命线系统的重要组成部分,准确判断其节点脆弱性对提高电力网络的控制、维护效率有重要意义。使用震害作用下节点的连通性概率,供电级数,及由节点度数计算的节点阈值作为判断电网节点脆弱性的指标,并利用可变模糊聚类模型,从而得到节点脆弱性的聚类结果,最终得到各节点的脆弱性排序。
The electricity network is an important part of lifeline network.Accurately estimating the vulnerability of node is significant to improve the efficiency of control and maintenance of power gird.An iterative algorithm based on variable fuzzy clustering method was proposed.By using disconnectedness probability,power supplying level and the threshold calculated from the node degree as judging index,clustering result under earthquake and sort it finally were obtained.
