Abstract

The invention relates to a CML-based intelligent substation equipment network node cascading failure risk analysis method, and belongs to the field of information safety. The network is established for the equipment nodes of the intelligent substation and the equipment connection between the nodes to evaluate the influence of different equipment nodes on the whole equipment network of the intelligent substation when a fault occurs, so that the information safety risk of the intelligent substation is effectively analyzed. The intelligent substation information safety risk analysis and management subsystem based on the model can assist a manager in managing information safety risk data of an intelligent substation and realizing data visualization, and provides accurate basic data support fornetwork safety evaluation of an intelligent substation system.

Description

technical field [0001] The invention belongs to the field of information security, and relates to a CML-based method for analyzing the chain failure risk of network nodes of intelligent substation equipment. Background technique [0002] Smart substation, as the core node of smart grid, the importance of its safety is self-evident. Once a problem occurs, the consequences may be disastrous. Some criminals may also use hacking technology to steal relevant information about smart substations, causing losses to national assets. Therefore, it is our important goal to analyze the possible risks of substations and ensure the information security of smart grid. [0003] Discussion on the security of power information system has become one of the research hotspots in the current academic circles. The JWG-DZ / B3 / CZ-01 working group of CIGRE consists of three special committees including DZ (power information and communication system), B3 (substation), and CZ (system operation and con...
