specific Embodiment approach
[0044] The core of the present invention is to provide a fragile correlation analysis method for electric power cyber-physical system lines, and a schematic flow diagram of a specific implementation thereof is as follows figure 1 As shown, it is called the first specific implementation mode, including:
[0045] S101: Using a pre-established simulation model, perform joint maintenance simulations for a preset number of times to obtain a high-risk accident database.
[0046] As a specific implementation, this step specifically includes:
[0047] A1: Obtain a preset number of high-risk maintenance records; wherein, the high-risk maintenance records are obtained by randomly removing simulated lines and / or information nodes in the pre-established simulation model in sequence until a major blackout occurs in the simulation model Record.
[0048] Removing the analog line and the information node is equivalent to removing the line edge cut off due to overload for the physical networ...
Embodiment approach
[0100] As a preferred implementation manner, the vulnerability tracking module 200 includes:
[0101] A potential group integration unit, configured to determine a plurality of potential binary item groups according to the high-risk accident database; the potential binary item group is the combination of shutdown lines included in each high-risk maintenance record in the high-risk accident database;
[0102] A potential group screening unit, configured to sequentially determine whether the frequency of occurrence of the potential binary item group in all the high-risk maintenance records exceeds a preset minimum support;
[0103] A fragile related group determining unit, configured to determine the binary item group as the fragile related group when the frequency of occurrence of the binary item group in all the high-risk maintenance records exceeds a preset minimum support.
[0104] As a preferred implementation manner, the vulnerability tracking module 200 includes:
