This paper develops a harmonic compensation approach for the stator output voltage of a stand-alone doubly fed induction generator (DFIG) feeding a nonlinear (diode rectifier) load. This load type is characterized by a nonsinusoidal stator voltage consisting of severe harmonic components, fifth and seventh ones, which deteriorate the performance of other loads connected to the DFIG. The aim of the...
This paper proposes a novel control method for operation of a DFIG-based wind generator under unbalanced stand-alone loads, connected directly with stator terminal of the generator. The effect of unbalance condition at loads causes torque pulsations on generator and the stator voltage unbalance that degrade the dynamic behavior of control system. To eliminate the negative sequence components existing...
