Análise de projeto e desempenho dinâmico do gerador síncrono à relutância através de simulação computacional

Abstract

The prolonged use of non-renewable energy sources has intensified global warming, increasing concern about minimizing the effects of fossil fuel combustion. In this context, the search for new renewable energy sources drives the development of electrical power generation systems capable of operating off-grid, especially wind systems. This work presents the analysis and performance of a self-excited synchronous reluctance generator coupled to a wind turbine, with emphasis on mathematical modeling and computational simulation in MATLAB/Simulink. The theoretical foundation is developed, along with the modeling of the wind turbine, the generator in the dq reference frame, the capacitor bank responsible for self-excitation, and the electrical load. The system is evaluated under different wind speed and load conditions, and the results demonstrate the self-excitation capability and system adaptability. Therefore, the feasibility of the self-excited synchronous reluctance generator for wind power generation in isolated systems is confirmed, highlighting its robustness, simple construction, and stable dynamic behavior.
