| 摘 要： | 电力网络中的某些重要节点对连锁故障的发生有着重要的影响。文中应用复杂网络理论，综合考虑节点在网络拓扑结构中的分布特性以及电网的电气特性，选取输电线路的电抗值作为权值参数，建立了电力网络的有权网络模型;提出了基于有权网络模型的电力网带权重的网络凝聚度及节点重要度评估指标;并以EPRI 36节点系统为例进行了暂态稳定时域仿真实验，仿真结果表明了该方法的有效性。

| Abstract: | Some important nodes in power grid have serious impacts on cascading failures.Choosing reactance of transmission line as the weight parameter,a weighted power network model based on complex network theory is established.The weighted network agglomeration is defined.The important node evaluation indicator is proposed based on the weighted power network model.With this method,both network topology of the power grid and distribution of electrical characteristics are considered.The time-domain simulation on EPR... |
