摘要：

An concept in term of electric component was introduced to reflect the impact of substation building structure on substation system based on conventional seismic fragility analysis. The substation damage grade was defined from the system level, and the failure state of substation system was evaluated by the connecting state of output line. According to the characteristics of substation system, an efficient algorithm for network connectivity analysis of substation system was proposed, which was improved on the basis of traditional war shall algorithm. Then the algorithm was applied to the seismic vulnerability analysis of substation system. A practical example was considered as study case. The results show that under the small earthquakes, the substation system is mainly suffered intact and slightly damaged, while under the large earthquakes, it's seriously damaged, and medium damage and destruction are dominant. The seismic damage of the substation system is gradually increased with the increase of the peak ground acceleration PGA. Increasing the number of output lines of the main wiring system helps to improve the seismic reliability of the substation. © 2020, Editorial Board of Journal of Huazhong University of Science and Technology.
