Automatic POWERING EVENT Analysis

Introducing the first version of the Powering Servers with automatic event analysis features for online and offline circuit monitoring. Includes modules for individual circuit dissection, event recognition, and more. Automated tools for fault identification, circuit locking, and data management. Essential for maintaining equipment functionality and preventing malfunctions.

  1. Automatic POWERING EVENT Analysis Adam, Arek, Gert-Jan, Ivan, Knud, Hubert, Markus, Nikolai, Nikolay, Odd, Reiner, Roman, Zinur and many others…

  2. Preamble 1st version of POWERING SERVERS ready for release early next week Support work of MP3 through continuous online analysis of powering events (with and without beam) Data driven mechanism, ie arriving PM RAW DATA FILES will be grouped into powering EVENTS, and are analyzed in SESSIONS Analysis session finishes typically some 7-8 minutes AFTER circuit trip and might (depending on the analysis outcome) SUPERLOCK circuits in case of equipment malfunctioning Analysis module included in initial release Single Circuit Event (SCE) module for dissection of event into individual circuit events 600A Energy Extraction 13kA Energy Extraction Quench Heater Discharge Analysis (QHDA) 600A Quench discard module FGC_ext analysis (for possible feedback issues) Automatic Powering Event Recognition (Summer module for final decision on event type, identification of fault source, FGC faults, MP features, circuit lock,…)

  4. ONLINE and PLAYBACK servers • ONLINE server • Launched from CCM or http://abwww/ap/dist/pm/powering/pm-powering-gui/PRO/pmpow-online-gui.jnlp • For real-time analysis in CCC • Completely automatic, including automatic confirmation & circuit locking • Keeps history of past 15 analysis sessions in memory • PLAYBACK server • Launched from CCM or http://abwww/ap/dist/pm/powering/pm-powering-gui/PRO/pmpow-playback-gui.jnlp • For offline analysis by equipment experts,… • Allowing replaying ANY event in the past • NO EFFECT ON LHC OPERATION, ie no circuit locking, etc…. • Manual confirmation/discard for potential saving of results • Keeps history of past 15 analysis sessions in memory

  5. What to do in case a circuit gets super-locked • Identify the super-locked circuit(s). Most likely the CCC will let you know, otherwise check the list of locked/super-locked circuits in the PIC SCADA • Circuits locked by POWERING SERVER will be marked in Comment

  6. What to do in case a circuit gets super-locked • Identify the EVENT during which the circuit was super-locked. If it is recent it will most likely still be present in ONLINE server, easiest to check PM Database (from CCM or https://cs-ccr-oas1.cern.ch/pls/htmldb_dbabco/f?p=117:1)

  7. What to do in case a circuit gets super-locked • Open the according analysis SESSION , either in the ONLINE server (if still present) or in PLAYBACK In PLAYBACK: Use File -> Load Event menu: In ONLINE: Use File -> Reconnect menu:

  8. What to do in case a circuit gets super-locked • Identify event source + cause of locking in ‘Overview’ tab, eventually browse to details in ‘Modules Graph’ tab

  9. What to do in case a circuit gets super-locked • Identify event source + cause of locking in ‘Overview’ tab, eventually browse to details in ‘Modules Graph’ tab

  10. What to do in case a circuit gets super-locked • If applicable, document reason for failure in MP3 logbook, unlock circuit after authenticating in PIC SCADA

  11. Let’s try some examples…. • 14-OCT-10 12.05.41.315000 PM • RQX.R1 @ -1.493402958 • CIRCUIT_LOCK: Locked because of heater discharge • 17-OCT-10 08.23.13.112000 PM • Sector 23 trip from 3.5TeV following quench test, Heater firing on MQ.14R2 • 23-OCT-10 06.52.25.085000 AM • Sector trip of A23 from injection current • Trip of RQ9.R2 (+ heater discharge) • RQTF.A23B2 @ 5.831202507 EE file not OK

  12. Conclusions Server ready to be released mid next week (announcement will be sent to EIS’s, operators and MP3 members) Limited number of modules included in initial version (a lot of tuning already done but tbc for e.g. 600A EE, 13kA EE, QPS_600….) Expecting <1 circuit locks per day (depending on activities), please document in logbook cases where you think the circuit lock was unjustified I’m available to help, don’t hesitate to call me if needed (I’ll receive as well automatic e-mails) Next weeks essential for learning with new system, will add new modules starting early next year
