摘要：

A substation is a complex system composed of a series of different types of electrical equipment interconnected by conductors. In order to study the seismic performance of substation as a whole system, this paper proposed a new system analysis method combining graph theory, fault tree and success path. In the proposed method, a directed graph logic model of the entire substation was built based on the location and connection logic relationship of each electrical equipment and the power transmission path in the substation. Regarding the number of out-lines that can function normally as the performance evaluation index of the substation, the seismic vulnerability analysis of the substation can be obtained based on the seismic vulnerability curve at the device level by the Monte Carlo simulation method. A case study was carried out on a typical 220kV substation by this method and vulnerable points of seismic resistance of the substation system were pointed out through sensitive analysis. © 2020 Chin.
