Enhanced Direct Torque Control for DFIM-Based Wind Turbines: Voltage Dip Resilience and Crowbar Protection Elimination

Abstract

This paper explores wind energy control systems, with a special emphasis on the implementation of Enhanced Direct Torque Control (DTC) in wind turbines that use Doubly Fed Induction Machines (DFIM). The main goals are to improve the turbines' ability to withstand voltage fluctuations in the power grid and remove the need for crowbar protection by including an LCL filter. The study highlights the crucial importance of Enhanced DTC in ensuring the steady functioning of turbines under demanding grid circumstances, including as voltage swings. The use of an LCL filter is crucial in reducing high-frequency elements, thereby minimizing the effects of voltage dips. Furthermore, the research emphasizes the enhanced control structure produced via the removal of crowbar protection, eventually enhancing the dependability of the system. Finally, the proposed work enhances the optimization of wind turbines that use DFIM technology by using sophisticated control algorithms. This adds to improving the efficiency and sustainability of wind energy production.
