Alternatives to the use of the crowbar circuit in DFIG based wind turbines during balanced voltage dips.
Most of the modern wind turbines are based on doubly fed induction generators (DFIG), with a back to back power converter connecting the rotor to the network. It is known that voltage dips at the stator terminals can cause overcurrents in the rotor windings, which could threaten the converter integr...
