摘要：

Seismic retrofitting of substations can significantly reduce damage caused by earthquakes. However, the current research mainly focuses on the optimization of equipment structure, and there is a lack of analysis of retrofitting strategy for substation systems. In order to find an efficient retrofitting plan from the functional level of the substation system, this paper firstly proposed a seismic resilience evaluation framework of substations, and studied substation retrofitting strategies from equipment. By using the Monte Carlo method to analyze the seismic resilience of a typical 220kV substation, it can be found that the importance of substation equipment changes under different earthquake intensities. The analysis has obtained the retrofitting scheme, which proves the effectiveness of the seismic retrofitting strategy of the substation. The retrofitting strategy analysis method based on the seismic resilience evaluation of the substation system function can provide a reference for the seismic retrofit of the substation. ©2022 Chin.Soc.for Elec.Eng.
