Abstract

proteção rápida à distância para redes de abastecimento de energia. a presente invenção refere--se a um método para detectar um curto-circuito (16) em uma linha (10) da rede de abastecimento de energia elétrica multifásica, em que os valores de amostra de tensão e de corrente são registrados e um sinal de falha é gerado se uma avaliação de falha realizada por um dispositivo de proteção elétrico (12a) indica um curto-circuito (16) presente na linha (10). para gerar um sinal de falha ainda mais rapidamente do que antes, em particular para falhas nítidas, valores de referência de tensão instantâneos são calculados a partir de valores de amostra de tensão e de corrente instantâneos registrados antes da ocorrência do curto-circuito (16), e valores de tensão instantâneos comparativos são calculados a partir de valores de amostra de tensão e de corrente instantâneos registrados antes da ocorrência do curto-circuito (16). então, um valor de referência de tensão retificado é calculado a partir de valores de referência de tensão instantâneos consecutivos e um valor de tensão comparativo retificado é calculado a partir de valores de tensão instantâneos comparativos consecutivos. o sinal de falha é gerado se a diferença do valor de tensão comparativo retificado e o valor de referência de tensão retificado excede o valor limite de disparo. a invenção se refere, ainda, a um dispositivo elétrico (12a) correspondente.
