This paper presents the results of analyses of the effectiveness of a Superconducting Fault Current Limiter (SFCL) on improving power system transient stability and limiting the fault current in a two-machine-infinite bus system. In this study, the system model with two SFCLs installed at each generator terminal was used taking 3LG (three lines to ground) fault at 12 fault points into account. These analyses were performed using EMTP/ATP. It is concluded that the use of SFCL with shunt resistance value of about 1.0 pu is effective for all fault points for the improvement of power system transient stability and the limiting of fault current
