Sistema de processamento de energia elétrica para conexão de aerogeradores de pequeno porte à rede de distribuição

Abstract

In recent years, the generation of energy through wind systems has grown significantly. However, distributed generation wind systems do not play a significant role in this growth. In this scenario, the present work aims to present the study of the wind potential in the Apucarana-PR region. Such study is carried out with the survey of wind profiles in this region, using the atlas of the wind potential of the Paraná state, the Weather Spark platform and anemometric data obtained by the system located in the Apucarana campus of UTFPR. Once these data present the possibility of exploring the region's wind potential, a survey of small wind turbines available on the market is carried out, within the micro and distributed mini-generation scope, applicable to these wind profiles. Finally, a power structure for the processing of energy from these small wind turbines is proposed. This system is composed of an uncontrolled six-pulse rectifier bridge, a DC/DC boost converter controlled in current and responsible for the system maximum power point tracking and a full-bridge single-phase DC / AC converter with voltage and current control for connection to the electrical network. The system will undergo validation through computer simulation considering the connection of a 6 𝑘𝑊 wind turbine.
