EDF « SPOC » PROJECT
SPOC : “Simulation Pour Optimiser la Conduite” = Simulation for reactor operation
optimization
EDF is developing a data management system to manage its nuclear power plants
electrical data, which aims to be used from the engineering studies to operation
and maintenance
Global objective of maintenance:
To help keeping unit outages as short as possible in order to optimize the
energy availability factor
Main objective of the project : to know (and simulate) which equipment is impacted
by the unavailability of a distribution switchboard:
During planning, in order to optimize the maintenance work
During the unit outage itself, in order to face unexpected events.
Other uses of the data management system : Engineering teams have to run
simulations for power balance calculations and other network analyses

EDF « SPOC » PROJECT IEC CONTEXT Even if the context is nuclear generation, EDF « SPOC » project handles only
electrical data, and no mecanical aspects or fluid flows…
The electrical network of a nuclear power plant is not very different from a
distribution electrical network
We re-used the existing CIM model (from 61970 and 61968 series) with some adaptations
The specificities of generation electric distribution network could be introduced in
IEC TC 57 project 61970-458 « CIM extension to Generation » (on hold since 2013) and in
61969-13 (WG13) Common Distribution Power System Model
Using CIM will facilitate the interoperability with electric network analysis tools
Will allow the use of CIM data validation toolsCIMug Using CIM for electrical data management in nuclear power plants | 06/2016

MODELLING THE NETWORKADAPTING CIM CLASSES FOR THE PROJECT
No part in CIM to describe internal electrical network of nuclear power plant
Use CIM and adapt classes and objects for our project
Nuclear reactor (power plant unit) electrical part ↔ substation
Focus on electrical part, considering the unit as a substation which contains Switchboards
(VoltageLevel)
To model an Electrical switchboard:
VoltageLevel is used for the container aspect
BusbarSection is used for the electrical connectivity aspect
Cabinet is used for the Asset aspect
To model a « bay »
Bay is used for the container aspect
Switch is used for the electrical connectivity aspect
Cabinet is used for the Asset aspect

MODELLING THE NETWORK AC/DC
AC and DC are separated areas in CIM and not all the objects needed to describe
nuclear powerplants exist in DC objects
choice to modelize everything with AC objects from the CIM
+ : existing objects
- : will complicate calculations and other network analyses
New attribute in « BaseVoltage » to specify AC or DC
Converters : rectifiers and inverters

MODELLING THE NETWORK CONTROL LINKS - SWITCHBOARDS
For a switchboard
125V switchboards supply the control part (relay) of 380V and 6,6kV switchboards
Without this supply, all switchboard bays switch off (except the ones with mechanical
hook)
Consider control part (relay) of switchboards as an EnergyConsumer
Add a Control link between VoltageLevel and EnergyConsumer to modelize the link between
switchboards and their Control part

Conclusion
• A prototype of SPOC data management system is under development, final version isplanned for 2017/2018
• Using the CIM allowed/will allow us to :– Create a profile and validate instances / this profile (with EDF CIM tools : Modsarus® and Riseclipse®)– Interoperate more easily with electric network analysis tools
• ~40 CIM classes were used :– We did not need to create new classes– We used AC CIM classes for DC representations (and specify AC or DC by adding an attribute to
« BaseVoltage »)– We created 2 new associations (for control links)– We added 4 attributes to « Cabinet », 2 attributes to « Bay », 1 attribute to « BaseVoltage » (to specify AC
or DC) -> new attributes will certainly be necessary in future versions
• These needs and changes could be reported to TC57-WG13 and 61969-13(through CIM issues ?)– Either for modification of CIM model– Or for integration in IEC TC 57 project 61970-458 « CIM extension to Generation » on hold since 2013 or
61969-13 « Common Distribution Power System Model » (WG 13)
