Direct Model Reference Adaptive Internal Model Controller using Perrin equation Adjustment Mechanism for DFIG Wind Farms

This paper presents the direct model reference adaptive internal model controller for doubly fed induction generator used in wind farms based on MIT rule adjustment mechanism in addition to Perrin equation adjustment mechanisms with improved internal model controller filter design. Direct model reference adaptive internal model controller is developed and it is tuned using MIT rule adjustment mechanism with adjustment mechanism derived from Perrin equation. Rotor current controller is designed using direct model reference adaptive internal model controller to improve the robust performance of the system. The performance is compared with both method and it is described. Flexibility of proposed method in shunt connection is illustrated, dynamic response under fault causes sag condition, like sudden drop in terminal voltage changes affecting the behavior of the machine, this phenomenon is simulated using MATLAB/ SIMULINK and it is presented.
