초록
This paper surveys areas of vulnerability to voltage sags in KEPCO system. The area of vulnerability can be defined as the region where the occurrence of faults will lead to voltages lower than the sensitivity threshold of equipment. The analysis of the area of vulnerability is essential for estimating system voltage sag performance and establishing efficient countermeasures for voltage sag problems. In this paper, two buses in KEPCO system were randomly selected and the areas of vulnerability for the buses were calculated by using dedicated software.
