The sensitivity of the DFIG to the grid disturbances such as a voltage dip restricts network stability and risks damage to generator converters during the fault period due to the over-current and/or over-voltage. It is now a requirement that wind turbine manufacturers demonstrate what is commonly called `Fault Ride Though' (FRT) capability in their turbine systems. The rotor crowbar, as a cost-effective and reliable method of protecting the power converters of the DFIG, was employed as a part of the FRT scheme. A computer model created in Matlab/Simulink was validated with the results of a 7.5kW experimental system.
