  1. Steam Turbine Performance Remote Monitoring Presented by Deborah H. Cioffi, P.E. ARIPPA Technical Symposium 2005

  2. The Old System Consultant Management DAS

  3. The New System Consultant Management MDA Sentinel (SM) DAS

  4. Benefits • Early warning of performance problems • Improved heat rate • Postpone outage based on heat rate • Reduced time spent on deciphering performance data • Monitor several systems (thermal, vibration, lubrication, etc.) • Post-issue analysis

  5. Example • A typical plant – single reheat unit • A typical problem – high vibration on startup • Information flow • Problem identification • Problem solution

  6. Typical Plant P T P T VP  P P P P T T P T  HP LP IP PWR

  7. Vibration Problem… HP LP IP PWR W th↑ P x-o ↑ HP Eff - PWR ↓ P 1st↓ What needs to be repaired during this upcoming outage? IP Eff ↑ P hrh ↑

  8. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  9. DCS Sensor Control System Data Acquisition System • PXI (Compact PCI) by National Instruments • Oscilloscope-sized • Can connect to DCS, Control System or directly to sensors • Alarm level notification to pagers, phone, email • Project-specific or continuous monitoring • Repeatability of measurement process

  10. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  11. User Interface acquired analyzed data / User interface displaying • Custom Reports • Data Filters, Algorithms • Analysis • Historic Data • Life Monitoring

  12. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  13. Local Data Storage • Acquired data is first stored locally on the host system or an external storage device. Local data storage

  14. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  15. Internet • Internet connectivity can be achieved via satellite, DSL, or T1

  16. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  17. Remote Server • Data is backed up to a remote FTP server for future remote data retrieval • Secured, monitored data center in Denver • User has the option of how long to store data

  18. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  19. The Thinker… • Thermal Performance • Vibration • Control Systems • Rotor Stress • Generator Partial Discharge • Startup MD&A Engineers

  20. Information Flow Internet User interface displaying acquired / analyzed data Local data storage

  21. Data Retrieval • Clients log into a secure web page on the remote server allowing them to view and retrieve data from their system.

  22. Remember that Vibration Problem… HP LP IP PWR Packings Rubbed

  23. Costs • First year ~ $60k • Subsequent years ~ $35k + • Depends on: • Number of data points • Frequency of monitoring • Number of engineering reports • Data storage life

  24. Questions • On thermal performance monitoring • Deborah H. Cioffi 518-399-3616 • On hardware and costs • Michael Winter 970-224-2223 x255

  25. Thank You! Steam Turbine Performance Remote Monitoring Presented by Deborah H. Cioffi, P.E.
