DFIG Model in MT Coordinates with MATLAB Implementation

The DFIG model in MT coordinates has been implemented in the MATLAB/Simulink environment with all necessary parameters preconfigured. This model enables comprehensive analysis of wind turbine electrical and mechanical dynamics through coordinate transformation algorithms that convert three-phase quantities to MT (stator-flux-oriented) reference frame. The implementation includes key functions for simulating generator-grid interaction, torque control, and power flow calculations using Park transformations and flux linkage equations. Researchers can utilize this model to study dynamic responses to wind speed variations and validate advanced control strategies like vector control and maximum power point tracking. The code structure incorporates modular subsystems for converter control, grid synchronization, and protection logic, allowing customization of controller parameters and fault ride-through capabilities. This MT-coordinate DFIG implementation serves as a foundational tool for wind energy system analysis, featuring configurable PI controllers, switching frequency settings, and detailed mathematical representations of machine equations. The model's architecture supports real-time simulation studies and facilitates performance optimization through parametric sensitivity analysis. By leveraging MATLAB's power system toolbox functions, users can extend the model to include grid code compliance testing and stability assessment under various operational scenarios, advancing research in renewable energy integration technologies.
