Due to load growth and environment problems, there is a growing need to modernize the distribution infrastructure with utilities. To satisfy with these requirements, combining DAS with IEC61850 should be positively necessary. However, an investment expense to replace the existing equipments based on DNP 3.0 by the new one based on IEC 61850 and a problem of protocol compatibility between two equipments are the chief obstacles. In this paper, we present the design of a gateway acting as a protocol converter between DNP 3.0 and IEC61850 in Distribution Automation System. The proposed gateway is composed of DNP Master, IEC61850 Server, Mapping Table of Data and Service and SCL Configuration Element. Based on the designed mapping table, the gateway processes power information(DNP) received from power facility and transmits IEC61850 data to the monitoring system or acts inversely. It supports a protocol compatibility between the existing facility operated in DNP 3.0 and the new one working in IEC61850.
