A locally-based agent protection system has been developed by KDN using its own technology. The system is designed to isolate and restore the failure section after only a few cycles, which is available on closed-loop and open-loop power networks.
The following picture shows a demonstration of the restoration flow chart. It operational flow is as follows: failure in a closed-loop network detection current flow 1:1 protection communication between FRTUs isolation the failure section in five cycles.
The Agent Protection System has various functions, such as, additional device using Smart-RTU, closed-loop protection system (CLS) using F/O device, algorithm for CLS, fault current source/load direction detection, IPbased communication protection (2.5cycle), fault location display, DOCR/DOCGR Algorithm, etc.
The protection system detects and sectionalizes the failure area after only a few cycles, so uninterrupted power supply is possible. Also the reliability was highly improved in the power supply system, due to the fast recovery algorithm.
