In this paper, transient stability improvement using bridge type fault current limiter (FCL) is presented in single machine infinite bus (SMIB) system with a double circuit transmission line. Three single-phase sets of the proposed FCL are installed at the beginning of feeder. The proposed FCL inserts an inductance and a resistance in the fault current pass. The insertion inductance and resistance not only limits the fault current level in an acceptable value but also improves transient stability of power system by consuming excessive energy of synchronous generator during fault. To reach maximum transient stability, the optimal resistor value of the proposed FCL is calculated. Analytical analysis and simulation results using PSCAD/EMTDC software are presented to show the current limiting future and transient stability enhancement using the proposed FCL in SMIB.
