Analysis of the Unbalanced Fault in Three-Phase Flux-Coupling Type SFCL Using the Symmetrical Coordinate Method.

The power demand is rapidly increasing in Korea, especially in the urban areas that include the metropolitan area. In addition, the transmission system in Korea is a network structure that ensures the high reliability and stability of power supply. Accordingly, the fault current rapidly increases in the case of a power system fault, due to the decrease in the line impedance. The superconducting fault current limiter (SFCL) was devised to address these existing problems refid="ref1"/refid="ref2"/refid="ref3"/ refid="ref4"/. [ABSTRACT FROM PUBLISHER]
