Abstract

sistema, método e meio legível por computador não transitório trata-se de um sistema de proteção diferencial. o sistema de proteção diferencial inclui um terminal local configurado para ser acoplado de modo comunicativo direta ou indiretamente a pelo menos dois terminais remotos por meio de pelo menos três enlaces de comunicação para formar uma topologia em anel ou uma topologia em malha. o sistema de proteção dife-rencial inclui adicionalmente um controlador que compreende uma unidade de decisão de enlace de comunicação e uma unidade de relógio associadas ao terminal local. a unidade de decisão de enlace de comunicação é configurada para determinar alguns dos pelo menos três enlaces de comunicação como desconectados virtualmente de modo que a topologia em anel ou a topologia em malha sejam configuradas para serem convertidas em uma topologia de corrente margarida. a unidade de relógio é configurada para sincronizar em tempo o ter-minal local com pelo menos um dentre os pelo menos dois terminais remotos quando o ter-minal local e os pelo menos dois terminais remotos são configurados na topologia de cor-rente margarida.
