  1. Extension of the Common Information Model with a Catalog of Topologies Proposal for IEC TC57 WG14 PhD. Dragan S. Popović MSc. Ervin Varga

  2. Motivation • To raise performance of the system with maximum knowledge about the physics of the problem. • To encourage the DMS vendors to use more of CIM based solution in the new generation of DMS software. • To get closer to internal CIM compatibility on modular level (efficient interoperability tests).

  3. The CIM connectivity model

  6. Catalog of equipment in CIM

  7. Inputs of a bay Outputs of a bay Bay External element 1 External element 2 The matching record in the catalog of bays describes the internal topology of a bay. The bay consists of several pieces of equipment, and their interconnections. Abay as a fundamental idea • interconnections of external elements through a bay • the bay's inputs/outputs • the bay's internal structure

CPU Time [s] CIM model 78 CIM model with proposed changes 73 19,1 15,1 Tested networks Novi Sad Puebla CPU Time [ms] CIM model CIM model with proposed changes 937 875 313 188 Tested networks Novi Sad Puebla Test results • the histogram showing the CPU times for serializing the networks of Novi Sad and Puebla • the histogram showing the topology analysis times for the networks of Novi Sad and Puebla

  13. Conclusion • The size of the CIM/XML document containing exported data about the network is reduced. • The speed of processing the topology of the network is also significantly reduced. • Accepting the proposal on an international level paves the way for standardizing the catalog of topologies. • The data management (input and verification) is enhanced. • The checking of allowed switching operations within the bays is lot simpler.

  14. Changes in basic CIM model or the application database • Introduction of the catalog of topologies is a natural extension of modeling topology parameters that already exists in CIM. • Introducing the catalog of topologies does not impose any limits to general modeling, or violate CIM compatibility, but provides many benefits. • Incorporating the catalog of topologies into an application database is useful for all applications, but very time consuming. Therefore, it would be better to apply it in the basic model.
