  1. CIM Support for Asset Health ModelingPat Brown, EPRI CIMug AHFC

  2. Integration Framework for Analytics

  3. The Common Information Model (CIM) • Semantic model for organizing ‘public’ (shared) information • 3 Sets of standards maintained by 3 IEC TC57 Working Groups • 61970 – WG13 – network models and related information • 61968 – WG14 – metering, assets, work (back office) • 62325 – WG16 – markets • Expressed in Unified Modeling Language (UML)

  4. Unified Modeling Language A Class

  5. Unified Modeling Language Inheritance

  6. Unified Modeling Language Associations

  7. CIM Packagesfor Asset Health • 61970 – grid position (role) perspective • classes describe network model and real-time measurements, from which asset exposure to field conditions and criticality can be determined • 61968 - asset perspective • classes for the asset itself, for manufacturer and model information, for inspection and test records and for lifecycle activities

  8. CIM Classes for Asset Health Asset & Asset Component “Tangible resource of the utility, including power system equipment, various end devices, cabinets, buildings, etc. .”

  9. CIM Classes for Asset Health Asset Information

  10. CIM Classes for Asset Health Asset Information (Informative)

  11. CIM Classes for Asset Health Asset Information – Model & Manufacturer

  12. CIM Classes for Asset Health Asset Procedures & Procedure Data Sets

  13. CIM Classes for Asset Health Basic Asset Model

  14. CIM Classes for Asset Health Basic Asset Model

  15. CIM Classes for Asset Health Network Model “A power system resource can be an item of equipment such as a switch, an equipment container containing many individual items of equipment such as a substation, or an organisational entity such as sub-control area.”

  16. CIM Classes for Asset Health Network Model & Asset

  17. CIM Classes for Asset Health Class Diagram Overview

  18. CIM Classes for Asset Health Sample Instance Drawing

  19. What’s next? • We need a framework for interoperability • Asset component ‘templates’ for common assets • Asset & AssetContainer usage • AssetInfo child classes • Starting with breakers

  20. Template – SF6 Dead Tank Breaker

  21. Upcoming Work • Identify common breakers • Develop ‘templates’ for each common breaker • Based on community understanding of what information is available and what components merit modeling • Use existing CIM as starting point and suggest enhancements as appropriate • Document using Enterprise Architect instance models • WG13/WG14 joint meeting next week • AHFC meetings will resume on Tuesday, July 1

  22. Common Breakers • Transmission • SF6 dead tank • OCB dead tank • SF6 live tank • Air blast (live tank) • Distribution • SF6 • OCB • Vacuum • Air blast • Air magnetic • Also reclosers, circuit switchers

  23. What can I do? • Provide input into common breaker types at your utility (send to Gowri at grajappan@doble.com) • Read Breaker Templates document • Covers CIM modeling for asset health • Suggests templates for 3 types of Transmission breakers • Reach out to other utility folks that might be interested • Join the call July 1
