【摘要】 变电站地震应急预案的制定与演练，以及震后电力应急处置工作的部署都需要对变电站地震损坏情况做出快速预测。本文在借鉴吸收国际变电站地震损坏评估方法及成果、统计分析国内变电站地震损坏案例基础上，采用专家调查法构建了3种电压等级（35 kV、110 kV和220 kV）变电站地震易损性函数，并提出了一种基于地震易损性函数的变电站地震损坏评估方法。利用该方法可以对变电站的整体损坏级别、设备损坏比例、震后恢复时间和经济损失快速评估。本文研究成果有助于变电站地震应急预案完善和震后第一时间电力应急处置工作的部署与开展。更多还原

【Abstract】 Formulating and performing exercise of the earthquake emergency response plan of substation, as well as deploying the postearthquake power emergency disposal work are premised on the rapid prediction substation damages. In this paper, based on referencing and absorbing the international methodology and results of estimating earthquake damage of the electric power system, and the statistical analysis of domestic substation earthquake damage cases, the earthquake fragility functions of 35 kV, 110 kV and 220 kV substations are constructed using expert judgment method, and proposed an estimation framework for substation earthquake damages based on earthquake fragility function. This method can be used to make an initial evaluation of the overall damage state, equipment damage ratio, restoration time and economic loss of substation. The research results will help to make and improve the earthquake response plan of substation, and the immediate deployment and implementation of electrical emergency response for occurrence of damaging earthquake.更多还原
