摘要
复杂系统理论是目前研究的一个热点,也是研究复杂电网连锁故障内在机理的最有力工具;该文首先介绍了电网连锁故障的研究历程及成果,然后根据对NERC15年数据进行的分析,说明电网大停电事故的长期关联性,并在此基础上分析了电网的自组织临界性及其对连锁故障的影响,最后简要地介绍了电网的小世界特性对连锁故障的影响。
Complex system theory is the most powerful tool for studying the general reasons of cascading failure in electric power systems,and it is also a popular research issues nowadays. In this paper, the achievements and development in the research on cascading failure in power systems are introduced first. Then according to the analysis of the data in 15 years from NERC, the long-term correlation of large blackouts is pointed out,and based on the statistical results,the property of self-organized criticality（SOC） in power systems and its effect are discussed. Finally,the small-world characteristic of the electric power network and its effect on cascading failure are qualitatively analyzed.
