Abstract
Fixed speed wind turbine generator systems suffer from various problems specially in transient conditions. So, in recent years the use of doubly fed induction generators (DFIGs) has increased significantly. DFIGs are sensitive to external faults. However, no attempts have been made to investigate the impact of increasing the carrier frequency of frequency converter/inverter for variable speed wind generators during voltage dip conditions. In this paper a suitable control strategy is developed for frequency converter/inverter to improve the low voltage ride through (LVRT) capability of DFIG based wind turbines. Simulation results indicate that the proposed topology improve the LVRT capability under grid codes. PSCAD/EMTDC software has been used for simulations under real wind speed data.
