Uma contribuição à aplicação dos filtros ativos em sistemas elétricos de potência

Abstract

The work in question aims to raise a state of the art consistent with the main three-phase active power filtering technologies, as well as to analyze the principles of operation and control of the same. In this way, computational implementations are performed for tests and case studies in order to evaluate some operating conditions of these equipment’s and the answers provided by the control algorithms implemented in various contour situations. In addition to the investigations carried out, complementary studies are done to present and perform some initial evaluations of the optimization trends of conventional converters to act as energy conditioners. Furthermore, discussions regarding the technical-financial feasibility of applying these solutions are carried out throughout the text, for the current scenario.
