Abstract
A feeding system feeds power from a power unit to a load via a feeding line and includes a protection device configured to operate by a current equal to or greater than a predetermined current; a monitoring unit configured to monitor whether an accident occurs in the feeding line; and a gate block unit configured to stop the feeding of the power of the power unit when the monitoring unit detects that an accident causing the protection device not to operate has occurred.
Claims12
A feeding system configured to feed power from a power unit to a load via a feeding line, the feeding system comprising:
- a protection device configured to operate with a current equal to or greater than a predetermined current;
- a monitoring unit configured to monitor whether an accident occurs in the feeding line;
- a gate block unit configured to stop feeding of the power of the power unit when the monitoring unit detects that an accident causing the protection device not to operate has occurred;
- and
- a control unit configured to operate the protection device after the gate block unit operates.
A protection coordination method performed by a feeding system configured to feed power from a power unit to a load via a feeding line, comprising:
- operating, by a protection device, with a current equal to or greater than a predetermined current;
- monitoring, by a monitoring unit, whether an accident occurs in the feeding line;
- performing gate block to stop feeding power of the power unit when detecting that the accident causing the protection device not to operate has occurred;
- and
- operating the protection device after performing the gate block.
