电网连锁反应故障研究新进展

由电网连锁反应故障造成的大面积停电事故一直是电力系统研究者的研究重点和难点定，虽然相应地提出了一些改进措施来提高电网的可靠性，但是事故仍然不断地发生。首先对当前国内外广泛使用的研究方法进行了综述．随后重点介绍了网络模型的最新进展．其中包括平均路长、集群系数、度分布这3个基水量，小世界、高度集团化．无标度的3个基本性质以及ER模型、WS模型、BA模型3个模型．同时还介绍了2种模拟连锁反应故障的方法，并且给出了相应的结果．最后讨论了这些网络横型和模拟方法．指出了它们的局限性以及应用前景．

Progress in the research of power system cascading failures

Since several decades,the study of large scale blackout from cascading failures in power system is important and difficult to power system researchers.Many measures are developed to improve the reliability of power system operations,however the blackout happens from time to time.First the most applicable methods were summarized in this paper.Then the latest network models were introduced including three parameters(average path length,clustering coefficient,degree distribution),three basic properties(small-world,highly clustered,scale-free) and three models(ER model,WS model,BA model).In addition,two methods of simulating cascading failures and the simulation results were provided.Finally the models and methods were discussed,meanwhile their limitation and prospective application are pointed out.
