| 摘 要： | 在分析连锁故障传播机理的基础上,充分考虑到网络结构的拓扑关系,分析系统潮流转移时线路的自临界特性,结合连锁故障发展阶段的概率特点,提出了基于线路集群的连锁故障概率模型。通过对连锁故障过程的模拟,用过负荷和系统负荷损失指标对连锁故障进行风险评估,找到系统的薄弱环节,分析降低电力系统连锁故障风险的预防策略。通过对IEEE39节点系统和甘肃电网的算例演示,验证了所构建的连锁故障概率分析模型的可行性和有效性。

| Abstract: | By analyzing the mechanism of cascading failure,the topological relations of network structure,the self-critical features of lines in the transfer of system flow,combining with the probabilistic characteristics of various stages of cascading failure,a probabilistic assessment model of power system cascading failure based on line clusters is proposed. Through means of simulating cascading failure process,the indices such as overload and loss of system-load are generated to evaluate risk of cascading failure,... |
