Controle Digital Simplificado para um Condicionador Unificado de Qualidade de Energia

Abstract

Este artigo propõe um sistema de controle digital simplificado para um condicionador unificado de qualidade de energia (UPQC). O UPQC é composto por um filtro ativo paralelo (FAP), empregado para o condicionamento da corrente drenada da rede, e por um filtro ativo série (FAS), utilizado para o condicionamento da tensão entregue à carga. O FAP e o FAS são controlados a partir da medição da corrente na rede e da tensão na carga, respectivamente, ao invés da medição da corrente do conversor paralelo e da tensão de saída do conversor série. Dessa forma, eliminam-se algoritmos complexos para geração dos sinais de referência dos conversores, uma vez que os sinais de referência das malhas de controle são senoidais e podem ser gerados internamente em um processador. A modelagem dos filtros ativos, a estratégia de controle proposta e o projeto dos controladores são apresentados em detalhes. Resultados experimentais obtidos em um protótipo de 2,5kW são apresentados para validar o sistema proposto.
