Abstract

a invenção refere-se a um método e a um dispositivo para detectar falhas em sistemas de transmissão e distribuição. o método é caracterizado pelas seguintes etapas: a. retificar o sinal de corrente alternada do sistema trifásico de "serviços auxiliares"; b. retificar e inverter o sinal de corrente alternada do sistema de transmissão e distribuição; c. ligar o sinal da etapa b à etapa a; d. medir o sinal de corrente alterna obtido na etapa b; e. medir a corrente contínua corrigida na etapa a; f. escalar o valor da corrente medida na etapa e por um fator de escala k; g. calcular o valor rms do sinal medido na etapa d; h. encontrar a diferença entre os valores obtidos nas etapas f e g; i. comparar o valor absoluto da diferença da etapa h com um valor de referência m; j. se a comparação realizada na etapa i for maior que o valor de referência m, gerar um sinal de trip e, manter a tensão entre os pontos de guia da etapa b entre 0 e 90% da tensão de operação sem falhas. o dispositivo compreende um retificador, um inversor conectado ao retificador, meios para medir a corrente conectada à saída do retificador e à saída do inversor, e uma unidade de controle conectada ao retificador, ao inversor e aos meios de medição de corrente, que realiza a ordem de trip do retificador e do inversor, e compara a medição da corrente alterna na saída do retificador com a corrente na saída do inversor, enviando um sinal de trip de acordo com a referida comparação.
