当前我国电力系统安全性评估主要是针对电力系统本身建模和故障分析计算，而对电网基础设施的脆弱性评估目前还没有公认的定义和统一标准。针对电网基础设施，在研究不同领域脆弱性概念的基础上，给出了电网基础设施脆弱性的定义，并在分析比较电网领域及城市基础设施领域脆弱性评估方法的基础上，提出了基于PSR模型的电网基础设施脆弱性评估方法及思路，以某500 kV变电站为例，进行脆弱性评估方法的实例验证，通过模型分析计算得出脆弱性指数，并依据标准判定其脆弱性等级为较轻。该方法的研究可为电网基础设施脆弱性评估提供重要的理论基础，可有效指导电网基础设施脆弱性评估工作的开展。

Safety assessment of power system in China has been long focused on network modeling and failure anal -ysis.Vulnerability assessment for important power infrastructures is a new concept appeared in recent years .There are no unanimous definition and norm to carry out evaluation .In this paper , a precise concept on vulnerability of power infrastructures was defined firstly based on the analysis on vulnerability in various fields .Then, several methods of vulnerability assessment in the field of power grid and urban infrastructure were compared .At last, ac-cording to the concentration and requirement , the framework of vulnerability assessment for electric power infra-structures based on PSR (Pressure-Status-Response) model was proposed, and then, taking a 500kV transformer substation for example , the case verification of vulnerability assessments was conducted .The vulnerability index was calculated by the model , and its level of vulnerability was determined to be light based on criteria .The method provides theoretic guide for promotion and development of infrastructure vulnerability assessment in electric power system, and can guide the vulnerability assessment of power grid infrastructure effectively .
