基于事故链的电网连锁故障分析方法应用

Research on cascading failure in power system based on theory of fault chains

通过运用基于事故链的连锁故障分析方法,在潮流稳定分析基础上,针对电网存在薄弱环节,进一步分析研究连锁故障对电网的影响,提出预防连锁故障的对策,为电网预防连锁故障诱发的大面积停电事故提供参考依据。

This paper analyzed methods of cascading failure based on the theory of fault chains and pointed out effects of cascading failure on the power system according to the weak link of power system.Moreover,countermeasures were proposed to provide reference for the prevention of the blackout accidents caused by the cascading failure of power system.
