This paper deals with modelling of Permanent Magnet Synchronous Generator (PMSG) based Wind Energy Conversion System (WECS) for extracting maximum power from the wind energy using Maximum Power Point Tracking (MPPT) algorithm. This design implements a variable speed wind turbine so that it can be operated at maximum efficiency for all wind speeds within the cut-in and furling speed limit in contrast to the fixed speed wind turbines. This design uses ACDC-AC topology. The converters use SVPWM to reduce THD (Total Harmonic Distortion). A hybrid MPPT algorithm is implemented using FLC (Fuzzy Logic Controller).Turbine, Generator and Drivetrain assembly is modelled using Two mass model-instead of lumping the inertia of the three masses-to study the dynamic response of the model as the MPPT algorithm changes the rotor speed according to wind speed variations.
