Simulink Simulation Model for Asynchronous Doubly-Fed Wind Turbine Generator

A Simulink simulation model for asynchronous doubly-fed wind turbine generators has been developed, enabling parameter modification and optimization. This model incorporates key components including the wind turbine aerodynamic block, doubly-fed induction generator (DFIG) electrical model, back-to-back power converter system, and grid-side control algorithms. The implementation features PWM modulation techniques for the rotor-side converter and space vector modulation for the grid-side converter, with proportional-integral (PI) controllers regulating active and reactive power flow. The model serves as an experimental platform for virtual testing and performance analysis, allowing researchers to study the generator's operational principles under various conditions. Through parameter adjustment and simulation analysis, users can investigate how different configuration settings impact generator performance characteristics such as efficiency, power quality, and dynamic response. The simulation includes maximum power point tracking (MPPT) algorithms for optimal wind energy capture and voltage-oriented control (VOC) strategies for grid synchronization. By iteratively modifying parameters and observing simulation outcomes, engineers can systematically enhance generator efficiency and reliability. The model supports comprehensive performance evaluation through scope monitors, power measurement blocks, and harmonic analysis tools, facilitating data-driven improvements in wind turbine design and operational strategies for more efficient and reliable wind power generation systems.
