基于电力信息物理系统实时仿真平台的网络安全仿真

Cyber Security Simulation Based on Real-Time Simulation Platform of Cyber Physical Power System

随着信息流和能量流耦合程度的不断加深,现代电力系统已逐渐发展成为信息系统和物理系统深度耦合的电力信息物理系统。传统的只对物理系统进行仿真运算的方法已无法保证其仿真分析的准确性。文章从仿真分析的角度,在对比分析现有仿真方法的基础上,进行仿真工具和配合模式上的改进,并进一步加入中间人环节,搭建了一种新的考虑网络攻击的电力信息物理系统(cyber physical power system,CPPS)实时联合仿真平台。最后,基于该平台,以负荷控制业务为例,研究了网络攻击对电力物理系统的影响,深入分析CPPS中信息系统与物理系统的深层次耦合关系,仿真验证了所提平台的有效性和实时性。

Modern power systems have gradually developed into cyber physical power systems that deeply integrate information flow and energy flow.Traditional simulation methods that only operate on physical systems cannot guarantee the accuracy of the simulation analysis.From the perspective of simulation analysis,on the basis of a comparative analysis of existing simulation methods,this paper makes improvements in simulation tools and coordination modes,and further adds a man-in-the-middle link to build a new CPPS real-time co-simulation platform considering cyber-attacks.Finally,the impact of cyber-attacks on the pow er physical system is studied w ith the example of load control business on this platform,and the deep coupling relationship betw een cyber system and physical system of CPPS is analyzed in detail.Simulation results validate the effectiveness and real-time performance of the proposed platform.
