| Abstract | ||
| The connection of doubly fed induction generator (DFIG) wind turbines to the grid and their dynamic behavior under different grid faults has become an important issue in recent years, and grid codes have been introduced, which is a challenge for the Wind Energy Conversion Systems (WECS). One of the most important issues related to grid codes is the low-voltage ride-through (LVRT) of wind farms. Based on such code requirements, wind turbine generators must remain connected to the grid and actively contribute to system stability during various grid fault scenarios. This paper presents the design and simulation of a protection strategy that uses a series resistor. It covers the theory, structure, and simulation analysis in MATLAB/Simulink to handle symmetrical and asymmetrical faults. The dynamic properties of the DFIG during the faults, which are examined from a variety of angles, validate the suggested performance of the protection mechanism. The ease of construction and cost-effectiveness of the recommended protection mechanism was proven by the simulation results. Additionally, by employing a series resistor design, the DFIG's performance is significantly enhanced for symmetrical and asymmetrical grid faults, outperforming protection schemes found in earlier works. | ||
