Abstract

In this paper, a generalized method for a wind inverter control under unbalanced operating conditions is proposed. The control method presented in this paper provides complete harmonic elimination in line currents and DC link voltage with adjustable power factor. The method is general and can be used for all levels of imbalance in grid voltages and line impedances. Simulation results for a variable speed wind turbine system with PM synchronous generator connected to unbalanced grid voltages and line impedances are compared to results obtained by using a standard control of a grid side inverter. In addition, the proposed method has been verified for a grid-fault ride through control of the wind inverter.
