Doubly Fed Induction Generators (DFIG) are majorly used in wind energy power generation. When DFIG system is subjected to symmetrical faults the wind turbine is disconnected and causes severe loss. When the system is at fault condition it should be connected with the grid without disconnecting is low voltage ride through capability which can be achieved with crowbar protection. The crowbar is connected to rotor side of DFIG and when system is subjected to symmetrical fault condition the crowbar is activated and have control over the system. In this paper, the behavior of 2MW DFIG is studied under severe fault. Simulation blocks designed using MATLAB-Simulink software on a 2MW DFIG system.
