Abstract: A three-phase wound rotor induction machine, operating as generator and driven by a wind turbine is interconnected with the power utilities grid. This is done through the enforcement of the machine to run at over synchronous speed conditions. Extraction of a maximum power from a wind turbine is made possible through the installation of a three-phase controlled bridge rectifier as a part from a slip energy recovery system. The controlled bridge converter is operated in the 'inverter mode of operation'. The installation of the controlled bridge converter results in the generation of harmonic currents. To overcome the effects of such harmonic currents, three-phase active filters are shunted with the induction machine. The shunted active filters guaranty the sinusoid quality of the power utilities line currents. The overall performance of the proposed configuration has been simulated in MATLAB/SIMULINK environment. Under different pretended wind speeds, quite satisfactory and encouraging results have been obtained.
