배전자동화용 보호협조프로그램 개선

The DASPRO (Protection Coordination Program for DAS) is one of the application programs for Distribution Automation System (DAS) of the KEPCO. Application programs developed by KEPCO provide optimal operation in distribution network. The DASPRO includes diverse functions to operate network as construction of database using existing information. creation of diagram for protection coordination. calculation of fault current. evaluation network. power quality monitoring, etc. The DASPRO can examine validity of setting values for protective devices by comparing to T-C curves. Unless the protection coordination is correct, the most suitable setting value for protection devices are displayed on the screen. In this paper, I will introduce the contents of the DASPRO.
