In this paper, a bridge-type high temperature superconducting (HTS) fault current limiter (FCL) is presented. The working principle of this HTS FCL is analyzed in detail. Two anti-parallel coils which are made of HTS tapes are main parts of the FCL. The superconducting FCL (SFCL) has no influence on power system in normal working state because the equivalent resistance and inductance of the SFCL are very small. However when a fault occurs, the SFCL may provide large resistance and inductance to limit the fault current due to quench of one coil. Considering heat is generated in one of coils when superconducting/normal (S/N) transition occurs, the coil can be isolated before too much heat is generated. The design of the SFCL is carried out, and simulation computation and analysis were completed so as to verify the SFCL design. The results reveal that the bridge-type HTS FCL has rapid response to limit fault current.

“…In addition, since the cable will lose superconductivity when the temperature of the cable rises due to an over current situation, resulting in damage of the superconducting material in this process, it is very important to design a protection scheme for the cable itself. In this paper, an individual protection system is designed for a HTS cable and superconducting fault current limiter (HTSFCL) and is verified using Real-Time Digital Simulator (RTDS) [6]- [8].…”

This paper proposes a novel power system protection scheme in the power system including high temperature superconducting cables (HTS cables) and high temperature superconducting fault current limiters (HTSFCLs). The superconducting power system utilizes the large-capacity and environment-friendly characteristics of superconducting power equipment. Since the superconducting devices are one of the most optimal solutions to enhance the robustness of the power system, especially in Icheon substation in Korea, the protection of the conservative relays and additional relays, differential and instantaneous overcurrent relays, should be alternated with a new optimal protection coordination under the changed system configurations. To find the optimal protection scheme, the power system with existing power devices, conservative relays, HTS cables, and fault current limiter has to be modeled in Icheon substation and the novel protection scheme has been verified through RTDS test with real-time relay test.
