Abstract

Recently, several kinds of superconductivity applications are implemented and evaluated in the utility power networks. The protection system for HTS(High Temperature Superconducting) power devices safe operation has not been established yet. For the protection of the HTS apparatus, a better understanding of the quench properties against fault current and appropriate protection devices are required. In this study, an algorithm of protection system is developed with respect to HTS power cable. The protection system of HTS power cable was analyzed in the simulated power system. Results obtained from simulation will provide much more decisive data in order to design a certain superconducting power device, and can give a good information for the installation in power system.
