Conversor Fonte de Tensão Trifásico, Filtro LCL, Modelagem MatemáticaAbstract
Este artigo apresenta, como principal contribuição, a proposta de modelagem matemática da entrada CC do conversor fonte de tensão trifásico (CFT) com filtro LCL, conectado à rede elétrica. Considera-se na modelagem a dinâmica do LCL e do controle de corrente injetada na rede elétrica. Para o controle de corrente do conversor, utilizou-se o controlador proporcional ressonante (P-ressonante) com compensação de harmônicas e o amortecimento do LCL, é realizado através do filtro notch. Com a modelagem proposta, obtém-se um modelo não linear, que é linearizado para obter um modelo que representa com precisão a dinâmica do lado CC do CFT, em torno do ponto de operação em análise, considerando o modo de operação do CFT (retificador ou inversor). Resultados experimentais comparados com os de simulação são apresentados, comprovando a validade dos modelos matemáticos obtidos.
