Study on interoperable exchange of IEC 61850 data model

The main goal of IEC 61850 standard is interoperability, i.e. the ability for intelligent electronic devices (IEDs) from one or several vendor to exchange information and use the information for their own functions. If IEC 61850 client can't acquire IEC 61850 data model of IEC 61850 server, the following real-time data communication will become impossible. Based on the research and analysis of substation configuration description language (SCL) and manufacturing message specification (MMS), two methods are put forward to exchange IEC 61850 data model, including the offline exchange based on SCL configuration tools and the online exchange based on MMS. In this paper, a prototype system based on the second method is designed, and interoperability and function tests prove the feasibility of the proposed scheme.
