Abstract
The present invention relates to a reclosing control system and method using a superconducting fault current limiter. The reclosing control system includes a superconducting fault current limiting device in which two circuits, each having a switch and a superconducting fault current limiter connected in series with each other, are connected in parallel with each other. A recloser is disposed between the superconducting fault current limiting device and a distribution line and is configured to control reclosing. The distribution line is connected to the recloser and is configured to transfer power to a load.
Claims14
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 SFCL.
A reclosing control method using a superconducting fault current limiter, comprising:
- a reclosing control system detecting a fault occurring on a distribution line;
- the reclosing control system, which detects the fault, tripping the distribution line;
- the reclosing control system determining whether the fault has been cleared by applying a carrier signal to the distribution line;
- and
- the reclosing control system controlling reclosing in consideration of a fault clearing time and a recovery time of a Superconducting Fault Current Limiter (SFCL).
