IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to make the bus protection less sensitive with communication link performance degradation. IEC61850-9-2LE implementation is analyzed and process bus based on Ethernet technology is considered. Transient element based conventional bus differential protection is used with split busbar configuration and finally demonstrates the reliability and feasibility of proposed technique for digital substation.
