On automatic generation of IEC61850/IEC61499 substation automation systems enabled by ontology

This paper presents an introductory step in the automatic generation of distributed control software for power distribution automation systems based on Ontology Driven Engineering enabled by industrial standards IEC61850 and IEC61499. The novelty of this approach is the ability of automatically generating the logical connections between the logical nodes. The paper covers the several stages of the transformation process, such as developing the IEC61850 ontology and the ontology transformation rules. The developed IEC61850 ontology includes the logical nodes descriptions and additional contextual relations between the logical nodes which is lacking in the IEC61850 SCL configuration language. Then, the IEC61850 ontology is transformed to an existing IEC61499 ontology, adding classes of IEC61850 logical nodes as IEC61499 function blocks in the IEC61499 ontology. The means of the transformation of the ontologies is based on the eSWRL sematic web rules language, an extension to the rule language SWRL. The end result is the development of an IEC61850 ontology and a set of eSWRL rules which facilitates the ontology transformation.
