A Real-time Searching System for Cascading Failures Based on Small-world Network

Based on small-world characteristics, the spreading inherent mechanism of cascading failures in power grid was studied in this paper. The results of the experiment show that the appearance of long-range connectivity increases 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 faults quickly and efficiently from massive real-time data of WAMS. The correctness and effectiveness of the proposed method are validated by an example.
