Abstract

APARELHO PARA PROTEGER UM SISTEMA DE ALIMENTAÇÃO ELÉTRICA, MEIO DE ARMAZENAMENTO LEGÍVEL POR MÁQUINA, E, METODO PARA DETECTAR FALHAS EM UM SISTEMA DE ALIMENTAÇÃO ELÉTRICA. Um módulo de distância quadrilátera pode ser usado para detectar falhas em um sistema de alimentação elétrica. Uma cobertura resistiva do módulo de distância quadrilátera pode ser definida por uma tela de resistência. A tela de resistência adaptativa pode ser adaptado para certas condições do sistema de alimentação, tais como fluxo de carga avançado e/ou um fluxo de carga inverso. Uma tela de resistência adaptativa avançada pode ser calculado em paralelo com uma tela de resistência adaptativa inversa. A tela de resistência adaptativa avançada pode utilizar uma quantidade de polarização adaptada para condições de fluxo de carga avançado e a tela de resistência adaptativa inversa pode utilizar uma quantidade de polarização adaptada para condições de fluxo de carga inverso. A detecção de falha pode compreender comparar as telas de resistência adaptativas tanto de avanço como inversa para estímulo e detecção de uma falha no sistema de alimentação, quando o estímulo satisfizer uma ou outra tela.
