Development of Automatic Power Restoration System And Operation in KEPCO Real Power System

Recently, according to a rapid increase of the power demand, the KEPCO's 154kV lines are continuously expanded and become to the more complex loop system. As a result of increase of the fault capacity and the unbalance of power load flow, the circuit breaker have been exceeding the capacity limit of those in the loop power system. To solve this problem, APRS application will be necessary more and more.
