考虑软件失效的信息物理融合电力系统智能变电站安全风险评估
Intelligent Substation Security Risk Assessment of Cyber Physical Power Systems Incorporating Software Failures
摘要
Abstract
With the deep incorporating of information and communication technology in power systems, the power system has involved into the cyber-physical power system. The application of software-defined networking theory into the cyber physical power system can improve the system flexibility and provide room for new functions. Under this circumstance, the assessment of intelligent substation security risk should consider both the information device hardware factor and software factor. This paper combines the specifics of software defined networking and cyber physical power systems and then divided the system into the application layer, the control layer, the cyber operation layer and the physical operation layer. Based on the function decomposed modelling method, this paper put forwards the system security risk assessment method incorporating the failures of application layer control and function software and cyber device application software. The calculation and sensitive analysis of the security risk of T1-1 substation is operated using the assessment method in this paper.关键词
