摘　　要：近年来国内外发生了多次连锁故障导致的大规模停电事故,造成了巨大的经济损失,因此电力系统连锁故障的研究日益受到重视。电力系统连锁故障是由某一个故障引发的一系列故障过程,其后果是造成大规模的停电事故和许多元件的相继开断。对连锁故障的模式搜索法、模型分析法以及风险评估等方面进行了介绍和综述,并从电网脆弱性评估、调整耐受性参数以改善电力系统鲁棒性的方法这两方面指出今后可能的研究方向。Many large - scale blackouts have taken place recently among different countries and brought huge economic damnify, therefore the study on cascading failure of power system is becoming more and more popular. Cascading failure of power system is a series of successive failures caused by one failure, which may result in large- scale blackout and unexpected trips of many critical components. This paper presents and reviews mode search method and model analysis method and risk assessment of power system respectively, and points out possible search directions from vulnerability assessment of power grid and method of improve robustness of power system by adjust fault - tolerant capability.
