METHOD OF RELAY PROTECTION AND AUTOMATION DEVICES FUNCTIONS SOFTWARE REDUNDANCY Russian patent published in 2025 - IPC G06F11/20 H02J13/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and automation of controlling technological processes of industrial facilities. Method comprises: exchanging messages between modules for exchanging UDP messages of platforms for program distribution of functions (PDF) about the current state of the platform and current running relay protection and automation (RPA) functions; detection of changes in the composition of functions by the UDP messaging exchange module and transmission of information on missing functions, appeared functions and duplicated functions to the module for calculating the target function; calculation by the module for calculating the target function of the value of the function in the form of a delay time for start for a specific RPA function; holding target function calculation module time before sending command for function start; sending, by the module for calculating the target function, a command to start the RPA function to the function launch control module if no information on the smaller value of the RPA function on the other platform was received during the holding time during the reception of UDP packets from other platforms; transmitting, by the function launch control module, a list of launched functions to the PDF status collecting and sending module and sending information on the platform status to the supervisor module.

EFFECT: redundancy of relay protection functions.
