近年来，连锁故障已成为引发电力系统大停电事故的重要原因。
In recent years, cascading failure has become an important cause of large-scale blackout of power grid.
在大规模电网中，由简单故障触发的电力系统连锁故障常常会引起大停电的灾难性后果。
In bulk power systems, cascading failures initiated by normal events often lead to blackouts.
摘缶要：将复杂网络理论应用于电力系统，特别是对级联故障导致的大电网停电事故进行研究，得到了广泛关注。
Abstract: : Applying complex network theory to power systems, especially to the research of the large power grid blackout accident caused by the cascade failure, has been widely concerned.
近年来国内外发生的多起大停电事故表明，保证电力系统安全稳定运行的难度正在逐渐加大。
Several large scale blackouts happened both domestic and abroad approve that ensuring securely and the stable operation of power systems are becoming more and more difficult.
所以，研究大停电事故后如何进行快速有效的电力系统恢复具有非常重要的意义。
Therefore, research on how to restore the power system quickly and effectively after the outages is of major importance.
因此，如何有效地防止电力系统连锁反应故障是避免大停电事故的关键。
This leads to blackouts. So prevention of cascading failures is the key to avoid blackouts.
概述了复杂网络理论在电力系统中的应用，重点说明了利用复杂网络分析大停电事故的方法和意义，以及如何从复杂网络的角度来分析和研究电力网络的动态特性。
Recent studies on the power systems collapse prevention and the mechanism of cascading failures have shown that the self-organized criticality (SOC) is the character of power system blackouts.
