Abstract

a presente invenção divulga um método para otimizar a operação de um sistema de arrefecimento do transformador, o sistema de arrefecimento correspondente, e um método para determinar a capacidade dos acionadores de frequência variável (vfd) que são utilizados no referido sistema de arrefecimento do transformador. o referido método compreende as etapas seguintes: pré-processar a entrada de dados inicial pelo usuário; coletar os dados on-line e calcular o comando de controle otimizado para atender aos requisitos de perda do transformador; variação de temperatura do óleo de topo e ruído; e executar as ações de controle, controlando um interruptor controlável e/ou o envio de um comando de controle a um vfd. em comparação com as técnicas anteriores existentes, as soluções propostas são muito mais intuitivas e práticas no campo do sistema de arrefecimento.
