Abstract
This paper presents a series of current control strategies for the DFIG under symmetrical grid voltage dips. The controllable range, the damping time constant of the stator natural flux and the torque fluctuations of six control strategies are analyzed and compared. The control strategies which have the largest controllable range, the smallest damping time constant of the stator flux and the smallest torque fluctuation are listed, respectively. The comparison is verified by simulations.
