Análise de uma turbina darrieus tipo H com gerador síncrono de imã permanente utilizando controle Fuzzy

Abstract

The increasing demand for renewable energy sources and the pursuit of more sustainable solutions have highlighted wind energy as a promising alternative. This study focuses on the modeling and simulation of a wind energy generation system using a Darrieus H-type turbine and a permanent magnet synchronous generator (PMSG), aiming to optimize energy efficiency through a fuzzy control system. The main objective of this study is to develop a detailed mathematical model for the wind turbine and the PMSG, implementing a fuzzy controller that adjusts the current based on the error and its rate of change. The simulation, conducted in MATLAB/Simulink, was designed to analyze system performance under different wind conditions, emphasizing energy conversion efficiency and system stability. The methodology includes the modeling of the turbine and the PMSG based on dynamic equations, as well as the design of the fuzzy control system. The simulation considers various wind profiles, and the results show that the fuzzy controller maintains the DC bus voltage stable, maximizing the generated power. The Darrieus H-type turbine model demonstrated effective conversion of wind energy into mechanical energy, with the PMSG efficiently generating electrical power. It is concluded that the use of a fuzzy controller in wind energy generation systems with Darrieus H-type turbines and PMSG is effective, providing stable and efficient operation even under variable wind conditions. This study contributes to the advancement of renewable energy technologies, offering a robust solution for integrating wind energy into the energy matrix
