A Conversion Method for SCL to CIM Based on Ontology Matching

There are structure and content differences between SCL,the substation configuration language defined in IEC61850, and CIM,the common information model contained in IEC61970, which lead to the data exchange barriers between the substation system with the power dispatching center. While the traditional configuration files conversion scheme based on model mapping exists a low efficacy problem in the search for mapping relationships between the two models.For this reason,we construct ontologies for SCLand CIM, establish semantic mappings between SCL and CIM by using ontology matching algorithm in which the rich ontology element features of SCL and CIM are utilized. And according to these mapping relationships, we realize the conversion of the substation instance configuration files SCD/XML to CIM/XML automatically, improving the automation level of the model files conversion.
