Harmonics Rejection in Stand-Alone Doubly-Fed InductionGenerators With Nonlinear Loads - 2016

ABSTRACT:

This letter proposes a novel technique to reject 6n ± 1 harmonics in the stator voltage at the point of common coupling (PCC) for a stand-alone doubly-fed induction generator (DFIG) supplying a balanced three-phase diode rectifier. These harmonics are rejected by using the rotor current controller in the elemental synchronous reference frame. The proposed control algorithm is predicated on a proportional integral controller and a bank of resonant filters. In this frame, each resonant filter within the rotor current controller has the likelihood of rejecting one try of the positive and therefore the negative stator harmonic voltages at the PCC. Experimental results with two.two-kW DFIG are shown in this letter.
