Abstract

"SISTEMA PARA SELECIONAR FONTES DE TENSãO E CORRENTE PARA DISPOSITIVOS DE RELé PROTETORES PARA PROTEçãO E CONTROLE DE SISTEMAS DE ENERGIA ELéTRICA". O sistema inclui uma pluralidade de elementos de aplicação de proteção para realizar várias funções de proteção de sistema de potência, incluindo, por exemplo, proteção de linha, localização de falha de linha, determinação de direção de corrente, verificação de proteção e sincronismo de disjuntor, entre outras. O sistema inclui fontes locais de informação de corrente e tensão para as funções de proteção, como também uma seção de recepção para receber tais valores de corrente e tensão de uma fonte remota, tal como outro dispositivo de proteção, como também outra informação de entrada necessária para as funções de proteção. Uma seção lógica de seleção é responsiva à saída dos elementos de função de proteção, como também os dados locais e remotos para determinar se as fontes primária ou local são para serem usadas. As saídas dos elementos de função de proteção são usados por uma seção de saída para controlar disjuntores de circuito e similares e também são transmitidas, com as quantidades de fonte local e remota, para outros dispositivos protetores.
