摘要：
本文基于小世界特性分析了电网连锁故障的传播机理，指出长程连接的出现增加了故障传播的广度和深度，从而对连锁故障的传播起到推动作用。以此为基础，建立了连锁故障实时搜索系统，采用优先级模块，可从WAMS采集到的海量实时数据中，快速有效的搜索到故障源头，并通过实例验证了该方法的正确性和有效性。 |

Abstract:
Based on small-world characteristics, the spreading inherent mechanism of cascading failures in power grid was studied in this paper. The results of the experiments show that the appearance of long-range connectivity has increased the breadth and depth of spreading, so that it pushes the cascading failure to spread forward. A real-time searching system for cascading failures using the priority module is set up to find the source of the failures quickly and efficiently from massive real-time data of WAMS. The correctness and effectiveness of the proposed method are validated by an example. |
