Problems solved by technology

Since the power layer and the communication layer show different operating characteristics, the power components and the information components are deeply interconnected, mutually restricting and influencing each other, presenting the complexity of multiple time domains and spaces, so there is a lack of a unified actual modeling method
Due to the modeling differences between the two, currently no single simulation software can characterize both power and communication models

Abstract

The invention relates to a network attack simulation method and system for a power grid information physical system. The method includes: a power system simulator simulates according to a preset power system event list, and sends simulation results to a network attack simulator through an information system simulator; a simulation attack event is established in the network attack simulator, and the simulation attack event is sent to the power system simulator through the information system simulator; and the power system simulator updates the power system event list according to the simulation attack event, and simulates according to the power system event list. According to the technical scheme provided by the invention, a network attack simulation platform is added in the built power grid information physical system environment, corresponding scale and intensity of attacks are set for different power network characteristics and information network characteristics according to different security level protection requirements, and the impact of network attacks on the power grid information physical system and the role of protection measures in the event of system instability are observed and verified.

Description

technical field [0001] The invention relates to the field of power system network attack, in particular to a network attack simulation method and system for a power grid information physical system. Background technique [0002] The network attack on the power system has the characteristics of strong concealment, long incubation period and low attack cost. Although it cannot directly destroy the primary equipment of the power, it can weaken or even completely destroy the normal function of the secondary system to achieve an effect similar to that of a physical attack. , have a serious impact on system stability, economic operation, and social stability. When the power is running normally, the failure of the secondary equipment will cause measurement loss or errors, which will affect the accurate perception of the power primary system by dispatchers; System (EMS) / Wide Area Measurement System (WAMS) and other secondary systems communication network failures or malicious attac...
