    Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Lima, Kleber; Córcoles López, Felipe; Watanabe, Edson H.; Teodorescu, R. (2009)
    Conference lecture
    Open Access
    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)
    Conference lecture
    Open Access
    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 

    Lima, Francisco F. A.; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Watanabe, Edson H.; Blaabjerg, F. (2010-01-29)
    Article
    Open Access
    This paper presents a new control strategy for the rotor-side converter (RSC) of wind turbines (WTs) based on doubly fed induction generators (DFIG) that intends to improve its low-voltage ride through capability. The ...
