Mapping of IEC 61850 to Data Distribute Service for digital substation communication

Digital substation is one key component of smart grid and requires real-time and reliable data communication platform. This paper investigates the feasibility mapping of IEC61850 by using Data Distribution Service, which is a real-time, reliable, and data-centric middleware standard proposed by Object Management Group. The mapping is based on publish/subscribe mode which provides more flexibility than another message-based or client/server based mapping techniques such as MMS and CORBA-TAO. Moreover, middleware based implementation reduce the developing time and complexities and improve the code reliability. Several tests of QoS have been carried out to verify the mapping, based on tools provided by RTI-DDS.
