Analysis on the Limiting Method after Half Cycle of Hybrid Superconducting Fault Current Limiter using Simulation

The increase of fault current due to large demand has caused the capacity of power machines in power grid to increase. To protect the power system effectively from the large fault current, several superconducting fault current limiters have been proposed. however, in order to apply superconducting fault current limiters into power system, there are many problems such as cost, recovery, AC loss, and cryogenic. In order to solve these problems, hybrid superconducting fault current limiter(HSFCL) was proposed. However, HSFCL also has a problem that is protective coordination in distribution system with HFSCL. In this paper, HSFCL limiting after half cycle modeled and analyzed about protective coordination.
