  1. Long shutdown 2013:Electrical distribution activities 09/03/2012IEFC 2012 Workshop F. Duval on Behalf of EN/EL group

  2. Activities during LS1 Ongoing consolidation & upgrade details After LS1 activities Electrical distribution activities • Next talk is dedicated to cabling activities (copper & fibres) IEFC Workshop - François Duval

  3. 3 different types of activities: Consolidation and upgrade of the Electrical Network The ageing EL infrastructure must be updated to significantly increase availability rate and to meet CERN new requirements. Beyond the present CERN needs, these renovation activities have been defined according to the future CERN power demand. That’s why EL have worked with users on a 15 years power demand forecast. A complete program of consolidation & upgrade have been defined until 2025 and will be edited soon. This program cost is estimated at approximately 80 MCHF and shall be concentrated on 3 long shutdowns starting with LS1. Activities during LS1 IEFC Workshop - François Duval

  4. 3 different types of activities: Maintenance operations Since 2009 and the LHC start up, many maintenance operations have been postponed (mainly on 400 kV and 66 kV substations) because Christmas breaks have been shortened and because LHC Cryo could not be stopped. These postponed maintenance tasks must be done in 2013 in addition to regular scheduled maintenance. A complete stop of the 400 kV will be necessary for 4 weeks (in April 2013) to maintain the 400 kV circuit breakers and accessories. RTE will take profit of this stop to run its own maintenance program on the Bois-Tollot substation and on the Genissiat/Bois-Tollot Over Head Line. During these 4 weeks, only 60 MVA will be available from the substation on Swiss SIG side. (close to A gate in Meyrin) 60 MVA are enough to run CERN with all accelerators turned off but the cost of energy is 1.5 times the French price. (Coordination needed to avoid high consuming LS1 activities during this period) Activities during LS1 IEFC Workshop - François Duval

  5. 3 different types of activities: Requests from users Many requests have been announced and must be detailed in terms of workload and schedule. The estimated EL contribution, for all the requests known today matches the maximum acceptable by EL The major requests, not including LHC, are LINAC 4 and its connection to the Booster HIE ISOLDE RAMSES system Filters and compensators upgrades Experiments: ELENA, COMPASS, NA62, East Hall B157 PS access project LIU activities Activities during LS1 IEFC Workshop - François Duval

  6. EL is increasing sharply its manpower in order to face a huge program of work. Manpower of EL was 72 in 03/2011, 82 in 03/212 and is expected to be 88 in 01/2013 Agreements have been signed with AGH Krakow to have 12 technicians operational in 2013. 3 fellows, 4 PJAS, UPAS and 2 tech. students already joined the group It’s important to have them early enough to integrate and train them so that they will be fully operational for the highest workload period Having more people will become inefficient because of a lack of supervision Activities during LS1 IEFC Workshop - François Duval

  7. Prioritisation In spite of the substantial increase of EN-EL resources our workload is already at 100% of our capacity Further requests will leads to prioritisation of activities by LS1 management Activities during LS1 IEFC Workshop - François Duval

  8. Ongoing consolidation & Upgrade • Reminder: • Replace ageing and/or not reliable equipment • Simplification for better operations and reliable protection systems • Standardisation for easier maintenance & operation • Elimination of identified weak points • Redundancy  availability • Characteristics adapted to the CERN future needs Reliability – Availability – Safety – Evolution IEFC Workshop - François Duval

  9. Ongoing consolidation & Upgrade SPS Power Cables: Layout • Power cables 3.3/18/66 kV, control cables and optical fibres  90 km in 7 km long trenches • Tubes buried in 2011 • Cables pulled in 2012 • Cables connected and commissioned during LS1 • Cost: 17 MCHF • 6 FTE IEFC Workshop - François Duval

  10. Ongoing consolidation & Upgrade SPS Power Cables: tubes laying IEFC Workshop - François Duval

  11. Ongoing consolidation & Upgrade 1971 SMB- SPS Power Cables: cables length 18 km cable > 80 joints 2011 18 km cable 8 joints IEFC Workshop - François Duval

  12. Ongoing consolidation & Upgrade SPS Power Cables: Pulling cables • Laying of cables during machine operation • Works executable out of LS1 period • Contractually shall be terminated before August 2012 • We ask to be allowed to pull the cables into the BAs during machine run (risk of theft) Pulling machine IEFC Workshop - François Duval

  13. Ongoing consolidation & Upgrade CCC Re-powering - Prevessin 2012 New 3.3 kV power generation station 2012New Substation BE91 Redundant feeders 18 kV network 3.3 kV secured network 400 V distribution network CCC IEFC Workshop - François Duval

  14. Ongoing consolidation & Upgrade CCC repowering - BE91 Substation • WHY: • Increase 18 kV Prévessin distribution • Creation of a secured power station for the SPS and Prévessin • Construction of a new LV substation to ensure full redundant infrastructure (EL + CV) for the CCC IEFC Workshop - François Duval

  17. Ongoing consolidation & Upgrade 66 kV in Meyrin- MEH59 Substation • Redundant feeder for Meyrin • Necessary step to cope with power increase after LS1 • Necessary step to allow Meyrin consolidation between LS1 and LS2 MEH59 - Outdoor 66 kV ME59 - Indoor 18 kV MEH59 ME59 B 112 IEFC Workshop - François Duval

  18. Ongoing consolidation & Upgrade ME59 Substation Configuration since 1966 • Two phases to redistribute power flow • After 2013, the rest of the job can be done during machines runs. 2014 • Rest of Meyrin Then… • Local distribution 18 IEFC Workshop - François Duval

  19. Ongoing consolidation & Upgrade Other projects • BA5 substation replacement • First replacement of 6 SPS substations • Replacement include 18 kV, 230 V switchboards and 48 V redundant battery charger system • 66 kV protection upgrade • Upgrade for advanced digital functionality • Replacement of ageing electronics • BE substation • Necessary redistribution of cubicles to add new feeders (BE91, New SMB, etc) • Computer center B513 dedicated loop • Power increase on ISOLDE loop means that B513 must be fed separately • New SCADA system for power network supervision • Developed together with EN/ICE using PVSS technology • Upgrade for new functionality (power flow forecast, event replay,..) IEFC Workshop - François Duval

  20. Many consolidation & upgrade activities on the power network have already started in parallel with beam operations. The final connections and commissioning, which can only be done during shutdowns, are scheduled for LS1. In other words, EL workload will be high in 2012 as well. Ongoing consolidation & Upgrade IEFC Workshop - François Duval

  28. After LS1 Activities Other activities • Replacement of SPS substations • North area consolidation & Upgrade • PS distribution Upgrade (with LIU) • West Area Upgrade (new projects) IEFC Workshop - François Duval

  29. Conclusions • The LS1 step cannot be missed by EL. Otherwise, most of the works will be postponed to LS2 (3 years) • The risk is a significant increase of failure rate due to: • ageing electronics used in core protection relays • ageing devices (> 40 years) • loss of possible alternative configurations because of increased power demands IEFC Workshop - François Duval
