Abstract

método para determinar uma distância a falhas elétricas em redes elétricas, método para determinar para determinar uma distância até uma falha elétrica em uma rede elétrica e sistema para determinar distância de falha a presente invenção refere-se à detecção de falha e, mais especialmente, à determinação de localização de falha e/ou direção de falhas em redes elétricas. o método para determinar uma distância a falhas elétricas em redes elétricas compreende receber (202) uma for ma de onda elétrica através de uma linha de energia elétrica (109); determinar (204) uma pluralidade de parâmetros elétricos nominais para a rede de energia elétrica, sendo que a pluralidade de parâmetros elétricos nominais é associada a um estado da rede de energia elétrica na ausência de p elo menos uma falha elétrica transitória na rede; amostrar (206) subsequentemente uma pluralidade de parâmetros elétricos da forma de onda elétrica quando a pelo menos uma falha elétrica transitória existir na rede; determinar (208) uma pluralidade de indutâncias com base, pelo menos em parte, em uma comparação dos parâmetros elétricos nominais e a pluralidade de parâmetros elétricos amostrados, sendo que a pluralidade de indutâncias é representativa de indutâncias presentes na rede quando a pelo menos u ma falha elétrica transitória existir na rede; e analisar (210) a pluralidade de indutâncias para determinar uma distância até a pelo menos uma falha elétrica.
