Abstract

MÉTODO PARA IDENTIFICAR A INDUTÂNCIA DE FILTRO DE UM INVERSOR DE GRADE. Método para operar um inversor (1), o método compreendendo as seguintes etapas: - por meio de uma unidade de circuito (4) do inversor (1), aplicar uma tensão alternada a uma linha de fase (3) na qual uma indutância de filtro (2) é disposta, - determinar uma corrente de bobina (iL) da indutância do filtro (2) e determinar uma tensão de bobina (uL) da indutância do filtro (2), - determinar um primeiro valor (L(Ix)) da indutância do filtro (2) para um primeiro valor da corrente da bobina (Ix), - se necessário, determinar pelo menos mais um valor da indutância do filtro (2) para pelo menos mais um valor da corrente da bobina, - determinar um perfil de indutância (6) da indutância do filtro (2) em relação à corrente da bobina usando o primeiro valor determinado da indutância do filtro e opcionalmente usando pelo menos um valor adicional determinado da indutância do filtro, - regular a unidade de circuito (4) do inversor (1) por meio de uma unidade de controle (5) para gerar uma corrente alternada na linha de fase (3), em que pelo menos um parâmetro de regulação é continuamente adaptado à corrente da bobina atual de acordo com o perfil de indutância dependente de corrente determinado (6).
