“…Typically, a half-bridge converter powers the machine [30]. As a durable, reliable, and costeffective device with relatively straightforward control, VRGs have shown great potential as direct-drive machines in both off-grid WECSs [31] and grid-connected wind systems [32] (Figure 7). As a relatively new technology, PMAG can serve as a direct-drive generator in gridconnected [27] or isolated [28] applications, offering an improved power factor and enhanced overall performance.…”

Due to the unpredictable nature of the wind, uncertainty in the characteristics of wind electrical conversion systems (WECSs), and inefficient management tactics, wind turbines have historically had operational inefficiencies. In order to overcome these drawbacks, the hybrid excitation synchronous generator (HESG), an alternative to traditional generators, is presented in this study along with the suggestion to use robust regulators to regulate HESGs. This research begins with a thorough review of the literature on generators often seen in modern wind systems. Next, a simulation platform that merges a WECS with a HESG tied to an isolated load is built using the MATLAB Simulink environment. Pitch angle control investigation shows a new experimental approach to determine the link between turbine output and the reference pitch angle. Furthermore, an evaluation of the mechanical stability of the WECS is conducted by a comparison of the performance of a H∞ controller and a CRONE controller. The simulation results demonstrate the efficiency of the CRONE controller in reducing mechanical vibrations in the WECS. By reducing vibrations, the proposed control technique enhances the overall performance and efficiency of the wind turbine system. The field is extended by the demonstration of how HESGs and reliable control systems can enhance wind turbine performance while eliminating inherent limitations.

“…Todavia, nas últimas décadas, com as evoluções da eletrônica de potência, das técnicas de controle e dos microcontroladores, há aplicações em que a MaRV tem se tornado cada vez mais viável para substituir as máquinas elétricas convencionais de indução, síncrona e de corrente contínua (Ahn & Lukman, 2018;Pyrhonen et al, 2013). Essas aplicações são, em geral, as que demandam acionamentos com velocidades variáveis, como no caso dos geradores eólicos, que são submetidos às diversas condições climáticas e devem se adequar a velocidade momentânea do vento (Rahmanian et al, 2017;Viajante et al, 2018;Lu et al, 2020).…”

O motor a relutância variável (MRV) tem sido considerado uma alternativa viável para substituir os motores elétricos clássicos em aplicações que demandam acionamentos com velocidades variáveis. Este motor é robusto, dispõe de uma construção simples e tem a vantagem de possuir um rotor que não necessita de enrolamentos ou ímãs permanentes para operar. Neste trabalho, um MRV 8/6 tetrafásico é projetado a fim de substituir um motor de indução trifásico (MIT), utilizando a mesma carcaça disponível. Na metodologia adotada para o projeto, os dados mecânicos da carcaça do MIT são utilizados como parâmetros iniciais para o cálculo das dimensões do MRV. A escolha dos ângulos dos arcos dos polos do MRV é otimizada através da análise por elementos finitos. Além disso, as simulações realizadas via elementos finitos possibilitam a visualização da distribuição do fluxo magnético na estrutura do MRV e o levantamento de dados importantes como os perfis de indutância e de fluxo concatenado, e o torque do motor projetado. O maior erro relativo obtido para a densidade de fluxo magnético no núcleo do motor foi de 1,69% e o torque resultante do MRV foi muito próximo do torque requerido inicialmente. Esses resultados apresentados validam o protótipo projetado e consolidam a metodologia de projeto utilizada.
