Abstract :
In this paper, Low Voltage Ride Through behavior of vector-controlled DFIG wind turbine is studied and the modeling method and simulation result are presented. Now many grid codes require wind turbines keep connected during grid fault and provide reactive current when needed. To enable wind turbines ride through grid fault special protection measures have to be implemented. Usually a circuit usually called as crowbar is used to limit the over current in rotor circuit and overvoltage in DC-link. The behavior of the DFIG turbine during grid fault is simulated using PSCAD/EMTDC software.
