Proposição de filtros sintonizados para uma planta eólica em operação no nordeste brasileiro a partir de estudos computacionais e análise das distorções harmônicas.

Abstract

The growth in the use of wind energy in Brazil and in the world has been occurring rapidly, the gain of energy encouraged and private, becoming an increasingly competitive and attractive source of energy. Consequently, a change between wind farms and the connection networks that are found as sources of data of primary energy, are shown intermittently and using electronic converters. According to the operational functionalities, although there is recognition of a fundamental function of the wind works, it is related to the performance of a fundamental frequency, or the installation of the installations accompanied by a category of electric energy quality, harmonic distortions of voltage / current, which can interact and receive impacts in the electrical connection networks. In the context of the interconnections discussed here, the topic presents major challenges in order to motivate the developments carried out here, which are focused on studies on the mitigation methods of harmonic distortions in the system. Thus, the present work performs an analysis of a park that is connected in the interconnected system in northeastern Brazil, presenting mitigating solutions, through studies and analysis of the harmonics present at the point of connection.
