Detecção e diagnóstico de falhas em conversores de potência back-to-back utilizando modelagem inversa
(Universidade Estadual Paulista (Unesp), 2019-07-30)
Neste trabalho, é realizado o estudo da aplicação da inversão de sistemas dinâmicos para diagnóstico de falhas nos IGBTs dos conversores de potência de dois nı́veis CA-CC-CA bi-direcionais (back-to-back) aplicados na geração ...
An exact optimization strategy for the restoration problem in radial distribution systems with switches allocated in a reduced number of circuits
(2018-06-25)
In this paper, an adapted mathematical model is presented to the optimization of the restoration problem in radial electric power distribution systems with the existence of a reduced number of switches, which is the typical ...
Aplicação da lógica fuzzy em um sistema de pré-análise de oscilografias em unidades de geração
(Universidade Tecnológica Federal do ParanáPato Branco, 2011-11-25)
Nowadays it is a common practice to have digital fault recorders installed in most electric power systems (SEPs) installations. These devices perform a continuous monitoring function recording any disturbances related to ...
