- Abstract
During the low‐voltage ride‐through (LVRT) of the doubly fed induction generator (DFIG), the change rate of the stator flux is introduced as the feed‐forward compensation (FFC) to prevent the stator flux oscillation from affecting the rotor current control. The dual‐sequence FFC is proposed for the asymmetrical LVRT of the DFIG. To reduce the rotor voltage increase due to the FFC, the controllable resistive‐type fault current limiter (CRTFCL) is implemented at the stator side to improve damping to the stator flux oscillation. The resistance of the CRTFCL is controlled based on the ramp function to relieve oscillations resulted from the switch‐out of the CRTFCL. With the dual‐sequence FFC and CRTFCL applied to the asymmetrical LVRT, analytical expressions of the stator current, rotor current, and rotor voltage are derived. The accuracy of the analytical expressions and the improved LVRT performance with the dual‐sequence FFC and the CRTFCL are verified based on the time‐domain simulations. © 2020 Institute of Electrical Engineers of Japan.
