PROTECTION COORDINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a protection coordination system configured to limit a fault current generated during a fault by arranging a current limiter on a line of a power distribution system, thereby providing instantaneous protection coordination among relays.

SOLUTION: The system comprises: a first relay arranged on a first load line of a power distribution system; a second relay arranged on a second load line farther distanced from the center of the power distribution system than the first load line; and a current limiter arranged on a line between the first and second relays to limit a fault current generated on the second load line to a predetermined scope.
