Conversion of Breaker Oriented Model into CIM objects

This presentation explores the conversion of Breaker-Oriented Model (BOM) into CIM objects, focusing on EMS applications, dispatcher training simulators, and the migration process. It discusses the advantages of utilizing Bay Objects in CIM, the complexities of DTS in EMS, and emphasizes the importance of this transformation in modern power system analysis. Presented by Karel Máslo from ČEPS, a.s., at the 2011 Prague conference.

Presentation Transcript

  1. Conversion of Breaker Oriented Model into CIM objects Karel Máslo Department of Transmission SystemAnalysis ČEPS, a.s. 10-13 May 2011, Prague, Czech Republic

  2. Contents • ENTSO E CIM – Model Exchange Profile • CIM Using for EMS Applications • Dispatcher Training Simulator -DTS • Basic network model – BROM versus BOM • Extended model –protections and automatics • Migration to CIM • Conclusions

  3. Comparing data format UCTE - DEF • kB versus MB of data • transparent versus unreadable • easy transfer to other formats versus !?! CIM

  4. EMS ApplicationDispatcher Training Simulator - DTS

  5. Bus Oriented Model - “BOM” Network model • Detailed • topology • Breaker Oriented Model“BROM”

  6. Extended models of protections and automatics

  7. Transformation from BROMthrough Bay Object to BOM Real structureBROMCIMBOM Bay A collection of power system resources (within a given substation) including conducting equipment, protection relays, measurements, and telemetry

  8. More complex substations topology up to 7 terminals 2 forjunctions 5 forreal busbars 4/3 3/2 Polygon

  9. Migration to CIM Presentstate 1st step ???

  10. Bay Object Advantages • Decreasing of nodes and branches numbers : • About 70% of nodes are junctions in substations • About 75% of branches are switches • Simplification protection model data • ….

  11. Conclusions • DTS is one from the most complex application in EMS • It requires huge input data to simulate real power system • Load flow data • Protection, automatics and control equipment data • Dynamic model data • Creating Bay object is the first step to using CIM • This way will be long and probably distressful • But it is useful and perhaps necessary • Thank you for your attention and in advancefor help Conclusions
