Power Control and Harmonic Current Mitigation from a Wind Power System with PMSG

This paper describes a wind power system working with control of active and reactive power as well as harmonic current compensation. Power control is made through stator flux oriented in machine-side converter. The active filtering is done by grid-side converter (GSC) causing to grid current waveform without distortions. The algorithm applied for harmonic mitigation has shown to be effective in improving of power quality. Simulation results confirm the effectiveness of the proposed research, since through the power control of permanent magnet synchronous generator (PMSG) and harmonic compensation on GSC was possible to deliver of power to electric grid, satisfactorily.
