Interface between distribution automation system and SCADA to minimize the feeder loss

Distribution automation has been issued in KEPCO (Korea Electric Power Corporation) and KEPCO developed two types of distribution automation systems (DAS). One is small DAS that has the functions of remote control, remote data acquisition, and remote setting with simple structure of low cost for small cities or rural area. It has been rapidly set up in 177 low-grade business offices from 1998 to 2001. KEPCO has just developed another larger DAS for the metropolitan area. It has been tested in three business offices by 2001 and set up in the rest of the branch offices from 2002. The large DAS with the structure of duplicate servers and hot standby backup has the functions of feeder automation, simulation and loss minimization in addition to small DAS functions.
