摘要
Abstract
actual components damage probability of power system in the earthquake is the foundation for seismic situation of electrical equipment and network seismic risk analysis. This article analyzes the characteristics of earthquake disasters, and points out that using seismic zoning is reasonable method for assessing area＇s intensity. Main components of substation and overhead lines in earthquake cases of failure probability analysis model based on seismic zoning are established combining with electrical equipment fragility curve. Finally, failure probability of substation components and overhead lines in Chengdu power grid is calculated with this method proposed. The results are still compared with the actual data which show that the method is effective.关键词
