SIMULATION RESULTS OF THE DFIG

Doubly Fed Induction Generators (DFIGs) play a critical role in wind energy conversion systems due to their ability to provide variable-speed operation and reactive power support. Simulation results of DFIG models help in analyzing performance under different operating conditions, such as grid disturbances or changes in wind speed.

A typical DFIG simulation involves modeling the electrical and mechanical components in MATLAB/Simulink or similar software. The stator is directly connected to the grid, while the rotor is interfaced via back-to-back converters, allowing for independent control of active and reactive power.

Key simulation results usually include: Rotor & Stator Currents – To verify dynamic response during grid voltage dips or transients. Active & Reactive Power Output – Demonstrates how the DFIG maintains power regulation under varying wind speeds. DC-Link Voltage Stability – Ensures the converter control system maintains stability under load changes. Torque & Speed Characteristics – Validates the effectiveness of the MPPT (Maximum Power Point Tracking) algorithm.

By analyzing these plots, engineers can optimize control strategies for improved fault ride-through capability and grid synchronization. The simulation also helps in validating theoretical models before hardware implementation.
