Simulation study on operating characteristics of superconducting fault current limiter in onemachine infinite bus power system

A simulation model of a Superconducting Fault Current Limiter (SCFCL) based on the experimental results was proposed. Simulation studies were performed in one-machine infinite bus system with parallel transmission lines, which corresponds to the experimental system. The simulation results agree well with the experimental ones. Power system operating characteristics of the SCFCL were investigated and discussed by simulation results Effects of the SCFCL to the power system are verified from the simulation results. It is shown that the SCFCLʹs make critical clearing time longer and improve the system stability.
