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

Some equipments are controlled (heater, electromagnet, engine)

Loss of control part: don’t know the state of the equipment

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)
