Fault Current Characteristics of the DFIG under Asymmetrical Fault Conditions [PDF]
Energies, 2015 During non-severe fault conditions, crowbar protection is not activated and the rotor windings of a doubly-fed induction generator (DFIG) are excited by the AC/DC/AC converter. Meanwhile, under asymmetrical fault conditions, the electrical variables oscillate at twice the grid frequency in synchronous dq frame.
