Superconducting de reactor protects power system by limiting the amplitude of fault current with its inductance. Therefore, it is very important to design and simulate the dc reactor precisely for making the power system stable and effective. In this paper, we designed the superconducting dc reactor of inductive superconducting fault current limiter conceptually and acquired the optimal design parameters by using Finite Element Method (FEM). We manufactured the superconducting dc reactor and tested its characteristics at cryocooler-cooled 20 K temperature. Moreover, compared experimental characteristics with simulation results and analyzed them. We introduced the design method of the superconducting dc reactor and the fabrication method of 1.2 kV/80 A class dc reactor for inductive superconducting fault current limiter. Finally, we performed the short circuit test and discussed the results.

I N THE 21st century, sciences and technologies related with superconductivity are rapidly growing. To strengthen national competitiveness and improve superconducting science and technology, 21st Century Frontier R&D Program funded by the Ministry of Science and Technology was planned in Republic of Korea. The 21st Century Frontier R&D Program aims to develop and commercialize High-superconducting (HTS) wire, superconducting cable, transformer, fault current limiter (FCL), and superconducting digital device until 2011. From out of these, the FCL is expected to enhance the reliability of utility network, increase the entire power quality, and reduce additional investments for upgrades. The inductive FCL is planned to develop the industrial technology for commercialization until third phase, 2011. The aims of this project are as follows; development of the 6.6 kV/200 A FCL in first phase, development of 22.9 kV/630 A, power distribution
