A novel superconducting fault current limiter (SFCL) based transient voltage stability scheme is presented for use in wind farms driven by doubly-fed induction generator (DFIG) during grid faults. The proposed scheme consists of active and passive self-acting voltage compensators. The active compensator is carried out by allocating the reactive power references between the stator and the grid side...
To satisfy with the low-voltage ride-through (LVRT) requirements from both the grid side and doubly-fed induction generator (DFIG) based wind turbine (WT) itself simultaneously, this paper presents a novel LVRT scheme by using a resistive-type superconducting fault current limiter (SFCL) connected in series with the DFIG rotor winding. The peak fault rotor current characteristics are obtained and...
