__Low Voltage Ride Through is an important feature for wind turbine systems to fulfill grid code requirements. In case of wind turbine technologies using doubly fed induction generators the reaction to grid voltage disturbances is sensible. Hardware or software protection must be implemented to protect the converter from tripping during severe grid voltage faults. In this paper the Dynamic Voltage Restorer (DVR) solution for LVRT of DFIG wind turbines is investigated by simulation results using a detailed converter model considering the switching and appropriate 2 MW wind turbine system parameter. To show the effectiveness of the proposed method the results are compared to a conventional fault ride through of the DFIG using a crowbar circuit. Measurement results on a 22 kW laboratory DFIG test bench show the effectiveness of the proposed control technique. Index Terms-Doubly fed induction generator (DFIG), dynamic voltage restorer (DVR), fault ride-through and wind energy.
