The physical laws which govern the flow of 并将该指标应用于电力网关键节点识别。对IEEE 39 节点系 power through network were studied. To solve the problem that 统和湖南某地区电网进行分析计算，时域仿真结果表明，所 classical complex network model can not explicitly incorporate 提指标比拓扑度指标更为合理有效。 the laws governing the flow of electricity within networks, the 关键词：关键节点；复杂网络；电气距离；节点电气耦合连 electrical distance between pairs of nodes was calculated 接度；无标度特性；脆弱性指标 according to superimposed principle based on the information contained in the character of power network. The characteristic 0 引言 identification model of power grid was built with
