Design, Modeling and Performance Analysis of Brushless Doubly-fed Reluctance Generator for Windmills

Wind generators play a crucial role in optimizing energy efficiency in wind energy systems. The selection of a suitable generator type is essential, as different generators are better suited for varying operational and environmental conditions. This paper focuses on the Brushless Doubly-Fed Reluctance Generator (BDFRG) and presents a detailed performance analysis of this generator. The study involves the development and simulation of the BDFRG model using MATLAB/Simulink software. The model is subjected to comprehensive analysis under various operational scenarios. Key performance parameters such as Total Harmonic Distortion (THD), Integral Square Error (ISE), Integral Error (IE), and Integral Time Error (ITE) are evaluated. These parameters provide a quantitative assessment of the generator’s performance in terms of efficiency, stability, and output quality. To validate the results, the performance of the BDFRG is compared with conventional generator systems, specifically the Doubly-Fed Induction Generator (DFIG) and the Brushless Doubly-Fed Induction Generator (BDFIG). The comparative analysis highlights the advantages of the BDFRG over these traditional systems. The results demonstrate that the BDFRG outperforms its counterparts across all evaluated parameters, making it a promising choice for achieving higher efficiency and reliability in wind energy applications. This study underscores the potential of the BDFRG in advancing the performance of wind energy systems and provides valuable insights into its application in real-world scenarios.
