The wind vitality is the favored for all renewable sources. In this proposed method, the classical wind generator will be replaced by the use of Doubly Fed Induction Generator (DFIG) technique which is integrated with Shunt Active Filter (SAF). The main aspire of prospect work is in the control of Rotor Side Converter (RSC) contribution for attaining maximum power extraction and to supply requires reactive power of DFIG. The Grid Side Converter (GSC) transfer the active power from the machine side converter into the grid through Shunt Active Filter for reimburses harmonics produced by nonlinear load. The proposed Wind Energy Conversion System using DFIG integrated with Shunt Active Filter is simulated by using MATLAB/SIMULINK.

INTRODUCTION Wind energy is an indirect manifestation of solar energy. Historically, wind energy was used for sailing ships and for generating small amount of mechanical power through wind mills. The advantage of using wind energy is that its potential as a source of power is reasonably good and that its capture produces no pollution. The problem associated with this type of energy is that it is in dilute form and the availability of the energy varies considerably over a day and with the season [1]. There has been a constant rise in the use of renewable energy resources. Global wind energy capacity soared by a fifth to 238GW at the end of 2011[2]. India being the 5th largest player globally, accounted for 16GW. Hence, an urgent need for substituting conventional energy sources by alternative (renewable) sources is exceedingly being felt. Such can be extracted from renewable resources such as solar, wind, tidal, biomass, hydro or any of the hybrid combination of these to meet the required power demand. A generator is a device that converts mechanical energy to electrical energy for use in an external circuit [3]. The doubly fed induction generator is an emerging trendsetting technology, presently used in some large wind turbines with variable wind speed operation. The two examples of DFIG are NEG Micon’s 4.2-MW/100-m diameter machine and 2- to 3-MW GE machine [6]. The DFIG is admired system in which the power electronic interface controls the rotor currents to attain the variable speed obligatory for maximum energy confine in variable winds. The most attractive feature of the doubly fed induction generator is that only 20 to 30% of the power needs to pass through frequency conversion as compared with 100% in the variable-speed synchronous generator. The named so as because the motor is fed from both stator as well as rotor [8]. In this paper, the model of DFIG based variable speed direct drive wind turbine generating system WTGs is developed. The main feature of the proposed topology is that the energy storage elements, such as inductors and capacitors, can be reduced in order to improve the reliability, and reduce size and total cost.
