  1. PI at NB Power Presented by Steve Boyko

  2. Introduction • About NB Power • Our PI history • Current PI status • Specific PI applications • Future PI applications • Observed benefits • Conclusions & questions

  3. New Brunswick

  4. About NB Power • Founded in 1920 • Provincially owned (crown corporation) • 2500 employees • 6,600 km transmission lines • Serves over 300,000 customers • Net generation - 4119 MW • $1.2 billion sales in 1998-1999 • 15 generating stations: nuclear, oil, Orimulsiontm, coal, gas turbine, hydro

  5. NB Power Today • Increasing challenges... • Transmission deregulation • Increasing competition

  6. NB Power Today • … create a need for: • Paying down debt • Greater efficiencies • Emphasis on the “bottom line”

  7. Deregulation • Transmission has been partially deregulated • Generators can sell “through” or “out” but not “in” • Division into business units: • Generation • Nuclear • Transmission & Distribution • Customer Service & Marketing

  8. NB Power’s PI History • First PI installation 1992 in new Belledune generating station: • PI 2 system provided by Westinghouse • 20,000 points

  9. NB Power’s PI History • Bulk tag purchase made in spring 1999 as Year 2000 replacement and standardization of historian platforms • Four new PI servers installed in summer 1999 • three power plants • Energy Control Center • Belledune PI 2 server to be upgraded to PI 3 in April 2000

  10. Current PI Status • 65,000 tags across five servers • 87 ProcessBook users • 76 DataLink users • Users access servers locally and across our WAN • Applications growing..

  11. Specific PI Applications • Shared ProcessBooks • Transmission system monitoring • Opacity monitoring • Web page captures • Web applications • Equipment running hours tracking • Report scheduling • Electricity marketing

  12. Shared ProcessBooks • Plants and business units have developed their own and most share them across our WAN • General process overviews, trends

  13. Coleson Cove Unit 2

  14. Dalhousie Scrubber

  15. Dalhousie Unit 2 Cycle

  16. Transmission Monitoring • NB Power oversees the Maritime Control Area • Standards for responding to loss of load or generation • NB Power is responsible for maintaining 60 Hz frequency on grid • We adjust the frequency by raising/lowering load on units • PI used to demonstrate compliance, prepare reports

  17. Frequency Control

  18. Opacity Monitoring • Provincial regulations stipulate that our Dalhousie plant must report an exceedance if we exceed 20% opacity in any 4 minutes of a 20 minute period • Very difficult to calculate using DCS • Many spikes due to rapping • Solution - PI-API!

  19. Opacity Monitoring • NT service written in C • Runs on PI server • Tracks opacities for each unit • Should an exceedance occur, it • generates a report of opacities during the period • alarms the unit operator

  20. Opacity Monitoring

  21. Web Page Captures • Our Generation Marketing group requires market information to make energy purchases and sales • Current information is generally available on the Internet • Historical information is either lacking or poorly organized • Solution - put it in PI!

  22. This...

  23. … becomes this!

  24. Web Page Captures • Software written using Visual Basic and PI-API • Captures web pages at predetermined intervals • Scans page source for certain strings, e.g. • “Current Cleveland Weather via PI” • Downside - dependent on page format not changing

  25. OSI DevNet • The DevNet home page shows the current temperature in Cleveland • Easy to capture and put into PI

  26. OSI DevNet • <strong><small>Current Cleveland Weather via PI</small><br><small>Temp. 39 F </small><small>Humidity 57 % </small><small>Wind 2 MPH</small></strong>

  27. Cleveland Weather in PI

  28. Web Applications • Some users require only a snapshot of the process • DataLink or ProcessBook is overkill • Solution - Web pages on Intranet via PI-API

  29. Sample Web Page Links More links

  30. Equipment Running Hours • Machinery needs periodic maintenance (lubrication, vibration testing, etc.)

  31. Equipment Running Hours • Done in past with PIM (Periodic Inspection and Maintenance) work orders • Time-consuming • Manpower-intensive • Current maintenance done on a running hours basis • Some equipment not attached to DCS • Solution - PI with manual entry

  32. Equipment Running Hours • Modern plants can calculate running hours from DCS points • Older plants perform manual entry into PI using Manual Point Data Entry Control • Visual Basic program (using PI-API) to extract data from PI • Microsoft Access front-end for users

  33. Report Scheduling • Needed automatic report generation solution • Replacement for ReportWriter and other reporting systems • Want to email reports to save paper • Solution - Visual Basic and PI-DataLink

  34. Report Scheduling • An NT service monitors: • date/time • digital trigger points • Loads Excel spreadsheets (with PI-DataLink calls) • Prints and/or emails them • Visual Basic front-end for configuration

  35. Electricity Marketing • NB Power sells energy to Eastern Canada and into the New England power market • Our Marketing group uses PI to track • energy prices • actual sales • unit availability • air temperatures • billing

  36. Outage Costing • Unit outages (trips) result in: • increased fuel cost for replacement power • lost revenue and/or opportunities • Marketing uses PI to tie lost megawatts and lost sales together to put a dollar value on an outage

  37. Outage Costing • PI provides critical information: • actual costs of an outage • cost of restoring unit quickly vs. lost revenue/opportunities

  38. PI Applications • Shared ProcessBooks • Transmission system monitoring • Opacity monitoring • Web page captures • Web applications • Equipment running hours tracking • Report scheduling • Electricity marketing • Use of PI-API, DataLink, ProcessBook

  39. The Future • Integration of more stand-alone systems (interfaces) • Performance monitoring • Investigate other products: • PI-BatchView • PI-ActiveView • SAP integration? • More Internet applications • More PI servers

  40. Observed Benefits • Much more data stored • Unifies diverse data stores • Widely accessible • Faster and easier analysis

  41. Conclusions • PI selected as standard historian platform for NB Power • Provides a robust platform on which to build applications • Endless applications...
