Maximum Power Extraction from WT under Climatic Conditions using Fuzzy Control Schemes

Wind direction and intensity always change in nature with respect to time. In wind turbine (WT) operation, the blade pitch angle (BPA) and yaw stability play a significant role to achieve the higher power output from the with permanent magnet synchronous generator (PMSG) system. A fuzzy logic based proposed control scheme applied to control the WT blade pitch angle and yaw movement accordingly. For testing purposes, the realistic conditions of wind velocity and direction are considered to investigate system performance. MATLAB/Simulink modelling for blade pitch angle, yaw angle and cable torsion control has been designed for PMSG driven by WT system. For efficient operation, a stepper motor utilized for yaw angle control, which is powered by hybrid PV/FC system. As far as, the system performance is investigated under realistic conditions satisfactorily.
