Recently, in the context of smart grid, the usage of the I EC61850 communication standard gets broader and br oader. Though IEC61850 has been used as communicat ion standard for substation automation, the scope that it is applied becomes wider and wider into area of distrib uted energy resources including storages, communicati on between substation and control center, feeder autom ation and EV charging for smart consumers. In the flow of this IEC61850, KEPCO are carrying out the develop ment of Smart Distribution Management System, and as a part of this R&D project, IEC61850 based Feeder IE Ds of distribution switchgear is being developed. In this paper, IEC61850 based data model, software & hardw are architecture of Feeder IEDs are presented. In additi on, protection coordination and service restoration sche me by using peer to peer communication among FIEDs are also presented for self healing operation of distribut ion network.
