Abstract

The GENI project for applying the 22.9 kV HTS cable and the SFCL to real power system has been progressed in South Korea since 2008. The HTS power devices were applied to the Icheon substation in the real Korean power grid in August 2011. This is the first demonstration of HTS power devices in South Korea. For a successful application, this paper proposes proper specifications of a current limiting resistor/reactor and an activating current for the 22.9 kV SFCL in the Korean power distribution system. These specifications are determined, considering the protection system of real Korean power system.
