A protective relay, system, and relay operation method which allows logic functions to be distributed amongst multiple protective relays associated with a power distribution system. The protective relays include communications ports for exchanging messages over a peer-to-peer communications network, and include programmable logic. Each protective relay receives logic operands contained in the messages from remote protective relays, executes logic equations using the received operands, provides protective control if needed, and outputs operands to other protective relays.
L'invention porte sur un système de relais de protection et sur un procédé d'exploitation des relais permettant de répartir les fonctions logiques entre plusieurs relais de protection associés à un système de distribution de puissance. Les relais de protection comportent des ports de communication servant à échanger des messages par l'intermédiaire d'un réseau de communication point-à-point, et comportent une logique programmable. Chacun des relais de protection reçoit des opérandes logiques contenus dans les messages provenant de relais de protection éloignés, exécute des équations logiques à l'aide des opérandes reçus, exécute si nécessaire les commandes de protection, et transmet les opérandes aux autres relais de protection.
