<abstract>Now-a-days, the penetration level of the wind generator system directly connected to the power system grid is rapidly increasing. Doubly Fed Induction Generator has been broadly used in Variable-Speed Constant-Frequency (VSCF) wind energy generation systems. The Doubly Fed Induction Generator (DFIG) based wind turbine system provides considerably better power delivery towards the demand. In this paper, the performance of DFIG based WT system during various types of symmetrical and unsymmetrical fault has been discussed. LVRT capability of the system based on the grid connection requirement during these faults is studied and discussed here. In this paper, a Crowbar protection device is discussed to overcome the undervoltage and overcurrent phenomenon.</abstract>
