摘要 近来,世界范围内接二连三地发生大规模电网停电事故,引起人们对电网可靠性的高度关注。文中从电网拓扑统计特性入手,在深入讨论小世界网络模型后,对美国西部电网和中国北方互联电网进行比较分析,得出中、美两国的大区电网都属于小世界网络的结论。在此基础上,定性分析电网的小世界特性对级联故障传播的影响。 Recently, successive power blackouts of large scale occurred in the world, which attracts researchers' attention to the reliability of power grid. This paper focuses on the analysis of power grid topological statistical property. After delving into the small-world network model, this paper compares western power grid of USA and northern power grid of China, and concludes that Chinese and American large-scale power grids fall in the category of small-world network. Then, the paper analyzes qualitatively the effect of small-world properties on the transmission of cascading failure in power grid.
