Patent ID: 8284529

Claim:
A reclosing control system, comprising: a superconducting fault current limiting device in which two circuits, each having a switch and a Superconducting Fault Current Limiter (SFCL) connected in series with each other, are connected in parallel with each other; a recloser located between the superconducting fault current limiting device and a distribution line and configured to control reclosing; and the distribution line connected to the recloser and configured to transfer power to a load, wherein the recloser detects a fault clearing time by applying a carrier signal when a fault occurs on the distribution line, and performs reclosing considering the fault clearing time and a recovery time of a relevant SFC, wherein the distribution line is connected to a bus to supply power to the load, and the recloser determines whether the fault has been cleared by detecting the carrier signal on the bus, wherein the recloser detects the carrier signal by detecting variation in an effective value on the bus.
