电力基础设施网络系统级联故障仿真模型研究

Simulation Model of Cascading Failures in Electric Power Infrastructure Network System

通过网电攻击电力自动化控制系统而破坏其物理设施已成为削弱国家战争潜力的重要方式。随着下一代智能电网的建立、物联网的形成和信息体系的完善,复杂的控制网络系统将面对更多的网电攻击威胁。从典型电力基础设施网络的信息物理强耦合系统建模研究出发,设计了模型的主要框架结构和关键算法,对日益突显的网电攻击而引起物理级联毁伤效果的分析评估研究提供了理论参考依据。

To destroy physical devices by launching cyber attacks on the electric power control system has become an important way of weakening a nation＇ s war potentials. Along with the developments of next generation smart grid, the internet of things and the informational system of systems （SOS） , the complicated controlling networks system is exposed to more cyber threats. Taking the electric power infrastructure network whose cyber and physical systems are closely coupled as a typical example for modelling and simulation, architectural structures and key algorithms are designed, which provides theoretic references for analyzing and evaluating the cascading effects of increasing cyber attacks on physical electric systems.
