Abstract: Transient stability a crucial aspect for doubly fed induction machine (DFIM). A DFIM-based arrangement is adversely operated due to faults, as the stator of generator is linked with the power grid. Even so, there is a obligation for the wind generator to be allied even during fault conditions. Hence , it is much crucial to increase the short-lived stability of the DFIM. For getting better stability of the DFIM, a R- type solid state fault current limiter is suggested in work. Here grounded faults were performed on test system to verify the upshot of the BFCL in transient stability enhancement. Simulations were done in SIMULINK domain. To illustrate the presentation of the proposed modified BFCL(R-SSFCL), its performance is compared with that of the SDBR & conventional BFCL. Simulation results gives the information that the modified R-SSFCL is a good efficient device rather than series dynamic braking resistor(SDBR).
