Abstract

"método e aparelhagem para eliminação de impacto do compensador na proteção de distância de linha", tem-se um método e aparelhagem para eliminação do impacto de um compensador na proteção de distância em linha, sendo que o método compreende: obtenção de uma primeira corrente de uma linha conectada a um compensador ou conversores em série no compensador, e uma primeira voltagem de um barramento conectada ao compensador ou linha conectada ao compensador; saimento dos conversores em série e dos transformadores em série caso a primeira corrente seja maior do que um limite pré-estabelecido de corrente e uma duração seja maior do que um primeiro limite de tempo pré-estabelecido; saimento dos conversores em série e dos transformadores em série caso a primeira voltagem seja menor ou igual a um limite de voltagem pré-estabelecido e a duração seja maior do que um segundo limite de tempo pré-estabelecido ajustando a voltagem de saída dos conversores em série para zero, e caso uma segunda corrente de um elemento correspondendo a primeira corrente atenda as condições que a primeira corrente necessita de atender; e por outro lado,, cancele o ajuste da voltagem de saída dos conversores em série para zero e obtenha uma primeira corrente caso uma segunda voltagem da linha correspondendo a primeira voltagem seja maior do que o limite de voltagem pré-estabelecido e a duração seja maior do que um terceiro limite de tempo pré-estabelecido.
