Beschreibung
Zusammenfassung:	System and method of asynchronous operation applicable to a wind turbine of the doubly fed type (dfig). It includes at least one winding rotor asynchronous generator (104); at least one power converter (102) capable of controlling the rotor currents of said generator (104) in amplitude, frequency and phase; it is characterized by comprising disconnecting the generator rotor dfig (104) isolating it from the power converter (102), short-circuiting the generator rotor dfig (104) and performing the operation of the wind turbine with the generator rotor (104) short-circuited and isolated of the power converter (102), to enable the operation of the wind turbine generator in asynchronous generation mode. It allows the continuity of the operation of the wind turbine in asynchronous mode, in case of lack of operability of the dfig double-fed mode.
