Aiming at the low voltage ride-through of Doubly-Fed Induction Generations (DFIG) under grid faults, the low voltage ride through protection strategy with a high temperature superconducting fault current limiter (HTS-FCL) is proposed. Based on the electrical and temperature characteristics of HTS-FCL, a detailed HTS-FCL simulation model is established by thermal-electrical analogy method. Based on the transient model of DFIG, the transient response of DFIG under power grid fault is derived, and the influence of parameters on the transient response of DFIG after HTS-FCL protection input is analyzed, the main parameters of HTS-FCL are optimized by the combination of fuzzy optimization and particle swarm optimization. The simulation results show that the HTS-FCL parameter optimization results have good applicability, and with the proposed strategy, DFIG enables low voltage ride through under severe grid faults.
