“…Em conjunto com a turbina, os geradores síncronos de imã permanente (Permanent Magnet Synchronous Generator -PMSG) são os comercialmente mais indicados neste tipo de aplicação (Saleh 2018;Santos 2015). Dentre as vantagens deste gerador, a principal está na capacidade de implantar o rastreio do ponto de máxima potência em uma ampla faixa de velocidade do vento (Sarvi, Abdi, Ahmadi, 2013;Vijayalakshmi et al 2015).…”

Algoritmos de rastreio do ponto de máxima potência (Maximum Power Point Tracking -MPPT), associados a conversores bidirecionais (back-to-back) e geradores síncronos de imã permanente (Permanent Magnet Synchronous Generator -PMSG), são vastamente utilizados para extrair a máxima potência de sistemas eólicos (Wind Energy Conversion System -WECS) de velocidade variável. Neste trabalho são avaliados e comparados diversos métodos comumente utilizados em sistemas eólicos, indicando vantagens e desvantagens. Esses métodos apresentam diversos pontos que dificultam sua utilização em sistemas de baixa potência. As simulações apresentadas neste trabalho indicam que o método do controle adaptativo e a sua modificação são ótimas alternativas a serem aplicadas, visto que são algoritmos perfeitamente adaptáveis as mudanças climáticas e não necessitam de sensores de medição do vento e nem do conhecimento dos parâmetros do sistema.

This research aimed to introduce a comprehensive mathematical modeling approach based on the maximization of the power coefficient (Cp) to obtain the regulation in pitch angle and tip speed ratio (TSP), taking into account the detailed power losses at the different stages of the power train of the wind turbine. The model is used to track the optimal power coefficient of the wind turbine power train, considering both direct (without gearbox) and indirect (with gearbox) drive configurations. The result of the direct driveline was validated with a 100 W horizontal-axis wind turbine experimental system. The model estimated the optimal value of Cp at 0.48 for a pitch angle of 0 degrees and a TSR of 8.1, which could be obtained at a wind speed of around 11.2 m/s. The results also revealed that, within the lower wind regime, windage, hysteresis, and eddy current losses dominated, while during higher wind regimes, the copper, stray load, and insulator gate bipolar transistor (IGBT) losses gained high values. The developed model was applied to a 20 kW indirect drive wind turbine installed in Gwadar city in Pakistan. Compared with the direct coupling, the optimal value of Cp was obtained at a higher value of the pitch angle (1.7 degrees) and a lower value of TSR (around 6) due to the significant impact of the gear and copper losses in an indirect drivetrain.
