      Accés obert
      The voltage oriented control in the synchronous reference frame (VOC-SRF) have been extensively used for controlling wind turbines based on doubly fed induction generators (DFIG-WTs) through the rotor side converter of ...

    • Control strategy for the rotor side converter of a DFIG-WT under balanced voltage sag 

      Lima, Kleber; Luna Alloza, Álvaro; Watanabe, Edson H.; Rodríguez Cortés, Pedro (2009)
      Comunicació de congrés
      Accés obert
      This paper proposes a new control technique to improve the fault-ride through capability of doubly fed induction generators (DFIG). In such generators the appearance of severe voltage sags at the coupling point make ...

    • Rotor voltage dynamics in the doubly fed induction generator during grid faults
