Abstract
© 2020 IEEE. Doubly fed induction generators (DFIGs) have some enthralling features which made them one of the most popular choices in power system. However, any kind of system abnormalities will directly affect the DFIGs as their stator windings are directly linked to the grid. To comply with the grid code, every DFIG based wind farms are required to ride through the fault keeping the healthy part of the system undisturbed. So, fault ride through (FRT) capability improvement is a mandatory requirement for every DFIG based wind farms. Superconducting fault current limiters (SFCLs) have been popular for decades in this regard. In this paper, a new hybrid superconducting fault current limiter (HSFCL) with bias magnetic field is put forth. The HSFCL is designed by combining a double split reactor with a high temperature superconducting (HTS) magnet which is non-inductive. For the validation, its performance has been compared with that of bridge-type fault current limiter (BFCL) and series dynamic braking resistor (SDBR). MATLAB/Simulink environment is used to perform the simulations. It has been found that, the proposed HSFCL outperforms both BFCL and SDBR.
