In this project we are implementing the Doubly Fed Induction Generator (DFIG) with an integrated active filter capabilities by utilising Grid Side Converter. In the paper Wind Energy Conversion System which is denoted as the STATCOM is used to supply the harmonics even when wind turbine is in shutdown condition. The grid side converter helps in supplying the harmonics in addition to its slip power transfer. Therefore the rotor-side converter is utilized for gaining the maximum power extraction and to supply the needed amount of reactive power to the DFIG. Control methodologies of both GSC and RSC are explained. Fuzzy logic controller is also used as a control method in this project for the better and accurate performance. By using the MATLAB/ Simulink we can verify the proposed method of the DFIG based wind energy conversion system.
