CENTRALIZED MICROPROCESSOR SYSTEM OF RELAY PROTECTION, AUTOMATION AND ALARM WITH REMOTE CONTROL Russian patent published in 2019 - IPC H02H7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely, to relay protection, automation and alarm equipment. Technical result is achieved due to that centralized microprocessor system of relay protection, automatics and alarm system with remote control comprises multiple connection devices in N distribution devices (DD), N centralized microprocessor control systems (CS) output relays N DD, Q centralized microprocessor CS of Q electric power plants (EPP) output relays, electric energy system (EES) CS, wherein each of the plurality of N CS of output relay and signaling modes of the corresponding DD from the plurality of N DD is connected to the corresponding plurality of devices of connection of the corresponding DD from the plurality of N DD, each Q centralized CS from the plurality of Q EPP is connected to the corresponding Q EPP N DD N CS and connected with Q-1 EPP CS, as well as with CS of output relays in compliance with EES protection and emergency automation algorithms, wherein each of the plurality of connection devices EPP Q EES N DD contains units of galvanic decoupling and preliminary scaling, unit of frequency filters, analogue-digital converter, microcontroller of communication and transceiver of communication channels of the ring topology, at that, CS unit of each N DD N CS is connected to the computer.

EFFECT: simplification of deployment, scalability, as well as increased speed of information transfer in DD of EPP, in EPP, as well as in EES as a whole.
