From few years, the generation of power from renewable energy sources concern in the aspect to enhance the power which can produced by conventional sources. In all renewable energy sources, the most contributors to power generation is the wind energy generation system. Now a day’s wind turbine with variable speed has more influence than fixed speed wind turbines because control of these turbines is easy and has efficient operation. For that reason Doubly Fed Induction Generator (DFIG) modeling is necessary for Wind Energy Conversion System (WECS). The considerable field in power control of renewable energy sources adds the grid connected DFIG based WECS. Generally these are having wind turbines associated with DFIG and turbine coupled DFIG is linked to grid with a power electronic converter. In this thesis grid side and rotor side controllers are constructed by using Proportional Integral (PI) controllers. To enhance the controllability PI controllers are replaced with Fuzzy controllers. This paper also shows the comparative study between PI and Fuzzy controller. Mamadani technique is used in fuzzy logic controller membership functions. In matlab-simulink that model is simulated and it shows that the behavior of the system. At the end of this paper results are conferred.
