The study of the effect of the harmonic distortions and the power factor in a system with presence of nonlinear loads becomes crucial to the quality of electrical energy. Based on this problem, this article uses the Conservative Power Theory to evaluate parameters associated to product quality, aiming to obtain subsidies for the design of tuned passive filters focused on the reduction of harmonic distortion indexes associated with voltage and current, in addition to contribute to the reactive compensation of the electrical system under research.
Abstract.With the increasing use of non-linear loads in electrical power systems, it is necessary to study the harmonic distortion, which if not considered in the power calculations may result in measurement errors. Therefore, this study aims to present a comparative analysis between two power theories in the frequency domain, Budeanu theory and IEEE 1459 standard, before a case study, in the presence or absence of distortions of a system electrical test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
