SOFTWARE AND HARDWARE COMPLEX OF THE DECISION SUPPORT SYSTEM FOR MANAGING THE RELAY PROTECTION SUBSYSTEM AND AUTOMATION OF A DIGITAL SUBSTATION IN THE CONDITIONS OF COMPUTER ATTACKS AGAINST IT Russian patent published in 2023 - IPC G06F17/40 

FIELD: electric power engineering.

SUBSTANCE: invention relates to the field of electric power engineering. The software and hardware complex of the decision support system for managing the relay protection subsystem and automation of a digital substation under conditions of computer attacks against it contains the module "knowledge engineer interface", the module "interface for obtaining data from an external knowledge base", the module "knowledge base editor", the module "expert data base" interacting with each other, module "knowledge base management system", module "knowledge base for situation recognition", module "knowledge base for recommendations formation", module "inference machine", module "reliability calculation", module "situation recognition and preparation of recommendations", module "explanation subsystem", module "linguistic processor", module "database with information from external systems", module "data reception interface from SOIB", module "user interface", module "data exchange interface with automated control system TP", the module "preparation and processing of logging logs", the module "database for storing logs", the module "data exchange interface with OZHUR".

EFFECT: technical result is to ensure the possibility of obtaining a stationary readiness coefficient of the IEU RZA of the CPS, taking into account the multifactor analysis, which allows us to estimate the probability of finding the IEU RZA of the CPS in a working state in an arbitrary point in time, to assess the reliability of the RPA IEU under certain conditions, as well as to improve the quality of operational and technological management of the RPA subsystem of the DPS when conducting computer attacks against it.
