Visualizing IED Interaction in Smart Substation

This paper presents an innovative method for IED interaction analysis in the IEC61850 based smart substation. By parsing the data from the substation SCD configuration file to extract the data model needed for graphical dynamic analysis, the solution acquires the real-time communication data of substation according to the SMV, GOOSE and MMS messages. Using Java graphing technology, the solution interprets the information in a visual way of expression to generate time-sequentially progressive display automatically. Such graphical representation forms a complete record of the actions, and provides a simple and clear analyzing view of a complex and difficult to understand process.
