电力信息物理系统易损性分析方法

针对电力信息物理系统（CPS）体系复杂、网络耦合、易损性分析困难这一现状，以近年来国内外电力系统毁伤相关研究成果为基础，构建了电力CPS的毁伤树模型.根据电力CPS节点重要性与故障级联毁伤特性，提出了一种基于节点重要性的电力CPS易损性分析方法，构建了易损性评估模型，并结合实例进行了分析说明.结果表明，该模型可用于电力信息物理系统的生存力研究，为目标抗毁伤结构设计提升提供支撑. 

Vulnerability Analysis Method for Power Cyber Physical System

Aiming at the current difficult subjects of complex power cyber physical systems(CPS) system, network coupling and vulnerability analysis, a damage tree model of power CPS was established based on the research results of power system damage assessment in recent years. Considering the node importance and fault cascade damage characteristics of power CPS network, a vulnerability analysis method was proposed based on node importance for power CPS, and analyzed and illustrated with examples. Results show that the model can be used to study the survivability of power cyber physics system and can provide a support for the design and improvement of target damage resistant structure.
