Doubly fed induction generator (DFIG) is the most popular machine for the wind power application that consists of the ability for variable speed operation and reactive power control with the help of power electronics converters. It is one of the prominent system that follows grid code requirement as it remains connected with the grid even during the fault occurrence. For making the DFIG continuity in the grid, low-voltage ride through or fault ride through (FRT) techniques are used. Fault current limiter is one of the major schemes used under the FRT. A saturated core fault current limiter (SCFCL) is used in DFIG system to enhance the FRT capability. The main property of SCFCL is the change in permeability between the saturated and unsaturated conditions of the magnetic core to concurrently provide low steady-state impedance and high transient fault impedance for limiting the fault current.
