EMS Application Dispatcher Training Simulator - DTS

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

Extended models of protections and automatics

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

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

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 Thank you for your attention and in advance for help Conclusions
