Conversion of Breaker Oriented Model into CIM objects Karel Máslo Department of Transmission System Analysis ČEPS, a.s May 2011, Prague, Czech Republic

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

EMS Application Dispatcher Training Simulator - DTS

Network model Breaker Oriented Model BROM Bus Oriented Model - BOM Detailed topology

Extended models of protections and automatics

Transformation from BROM through Bay Object to BOM Bay A collection of power system resources (within a given substation) including conducting equipment, protection relays, measurements, and telemetry Real structure BROM CIM BOM

More complex substations topology 3/2 4/3 Polygon up to 7 terminals 2 for junctions 5 for real busbars

Migration to CIM Present state 1 st step???

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 ….

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 Conclusions Thank you for your attention and in advance for help
