This paper investigates the operation of wind-driven DFIG under unbalance Voltage or unsymmetrical fault condition. According to grid codes__ampersandsignnbsp; worldwide, the wind-driven DFIG are required to supply reactive power during and after the fault. It has been observed that the conventional vector control method used for control of DFIG does not work well during fault conditions. To reduce the oscillations in electromagnetic torque and Stator Active power and to maintain constant DC link Voltage a new control strategy has to be presented. Sequential decomposition of positive and negative sequence currents and controlling it with PI plus proportional Resonant controller is adopted both on Rotor side and grid side converter.The paper presents a development in methodologies for controlling wind driven DFIG during fault ride conditions. In recent year improved control strategy using different Artificial Intelligence-based controllers are used to control the RSC and GSC without sequence decomposition.
