Abstract

método e sistema para proteção diferencial de corrente. proteção diferencial de corrente com compensação de corrente de carregamento é provida para um aparelho de potência, tal como uma linha de transmissão de energia. terminais individuais determinam dinamicamente suas contribuições respectivas, se qualquer, para o valor de compensação de corrente de carregamento quando disponibilidade de uma ou mais fontes de tensão muda dinamicamente dentro do aparelho de potência. terminais respectivos calculam contribuições locais a um valor de compensação de corrente de carregamento com base em medições de tensão locais. uma perda de uma fonte de tensão é manipulada ajustando multiplicadores para os pontos de compensação restantes para refletirem a corrente de carregamento total. uma contribuição local é suprimida quando a fonte de tensão local não está mais disponível. depois de aplicar as contribuições locais, uma análise de plano alfa pode ser usada para determinar quando disparar o aparelho de potência.
