摘　　要：针对现有的多种连锁故障分析方法中Manchester模型较符合电力系统实际情况,但却只包含快动态过程、未考虑高压直流输电系统的问题,通过加入直流输电线路的故障判断、交直流潮流计算和系统慢动态过程等环节,对原始Manchester连锁故障模型的计算流程进行了改进,使之适用于交直流混联电力系统,扩大了使用范围。算例分析结果表明,改进后的模型可用于判断多种元件突发故障情况下交直流混联电力系统的连锁故障模式和结果,可为连锁故障的预防和电力系统的安全运行提供参考依据。Among the existing analysis methods of chain failures, Manchester model is more in line with the actual situation of power system than others, except for inconsideration of HVDC systems and slow dynamic process. For its shortage, failure judgment of HVDC, AC-DC power flow calculation and slow dynamic process were added into the origi- nal Manchester model to make it applicable for AC-DC system and a wider range of use. The example results show that improved method can be used to determine chain failures mode and aftermath under several kinds of component failures, which provides references for nrevention of chain fallures and the safe operation of power system.
