Deploying SCADA data to web services for interoperability purposes

This paper describes an approach to publish SCADA data into Web Services to contribute to the Smart Grid vision in the area of interoperability among SCADA systems in electrical utilities. The SCADA data model is based on the Common Information Model (CIM) defined in IEC 61968, IEC 61970 and related standards. The approach has been tested for Web and mobile process monitoring applications, as well as for integrating SCADA data into an Enterprise Service Bus (ESB). The architecture proposed based on the reference architecture for power system information exchange is described as well as the semantic data model and some results are presented.
