With the development of hiah temnerature superconducting fault current limiter (SFCL). it is necessary to investigate its effects on the power svslem with SFCL installed. In this paper a theoretical analysis of power system transient stability with resistor type SFCL using Lyapnov energy function is presented, and a guideline for SFCL's parameter design is given. Digital simulation was also made. Both theoretical analysis and simulation results demonstrate that resistor type SFCL could improve the transient stability of power system.
