FILTRO ATIVO PARA CORREÇÃO DE HARMÔNICOS

Abstract

The energy quality has become a requirement studied, perfected and improved. This question is perceived when equipment does not operate at full capacity, when there are equipment failures and no life reduction equipment. With many consumers, households now have electronic loads such as oven, computer, fluorescent lamps, essential equipment for day to day and that provide the appearance of harmonics. In relation to industry, with a range of devices operating together on a daily basis, the problems caused are more intense, taking into account that the devices that are in operation are robust and expensive equipment requiring an in-depth study of this phenomenon. Harmonics appear through loads characteristic nonlinear. This peculiarity causes disturbance in the network, affecting it and bringing the harmonic disturbances. One of the methods used to reduce this disorder, and that will be addressed in this work, it filters, which serve to filter out impurities network and improve the quality of energy. The work presented aims to analyze an active filter to correct harmonic distortion, which have become frequent with technological advances, industrial and population growth. The analysis was based on a survey of references on the topic. To check the analyzes, a computer simulation was carried out, whose results show the effectiveness of the active filter action to correct harmonic distortion.
