Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a safety testing system and method for a smart substation. Background technique [0002] As a critical infrastructure of modern society, power systems are high-value targets for cyber attacks. Researchers combine access control, authentication encryption, intrusion detection and other technical means in the field of information security with the power production process to study the implementation of information security protection in power systems. In the process of digital and intelligent development, the power system has gradually developed into a cyber physical system (CPS) composed of the fusion of information system and physical system. In the power system, the smart substation is one of the main components of the power system. The information security and status monitoring of the smart substation are highly dependent on the information system, and a security incident ...

Problems solved by technology

[0004] (1) The information system of the traditional power system simulation platform generally simulates the physical system, and does not consider the impact of the information system on the primary system of the smart substation, so it is not convenient to realize the interconnection system of the security attack and defense information physical interaction of the smart substation

[0005] (2) The traditional power system simulation platform is difficult to meet the complex problems of cyber-physical hybrid simulation of security attack and defense in smart substations

[0006] (3) In the smart substation security attack and defense platform, discrete calculation processes and continuous physical information processes coexist in the system, and the physical information hybrid simulation process often consists of many parallel / concurrent physical activities or information events. The calculation process and information The fusion of physical processes makes the system behavior and state more distinct in space-time and dynamic uncertainty, but the existing power system simulation platform is difficult to describe the fusion characteristics of the two
