M&D solutions suite ultra-reliable, invaluable for avoiding forced outages at Desert Basin

In 2010, Salt River Project's (SRP) Desert Basin Generating Station received a CCJ Best Practices Award for applying an integrated suite of monitoring and diagnostic (M&D) and analytic software tools and solutions. Such tools were deemed especially important by plant management and staff because of the plant's operating duty. Desert Basin's five M&D solutions are the following:

  • GP Strategies' EtaPRO Performance and Condition Monitoring System.
  • Chromalloy Gas Turbine LLC's TIGER® Monitoring System.
  • Siemens Power Diagnostics™ Service.
  • GE Intelligent Platforms' (formerly SmartSignal) Cycle Watch and EPI-center/Shield. more

Desuperheaters: Affordable, timely replacement requires precise planning, skilled labor 

Owners of F-class heat-recovery steam generators (HRSGs) installed during the bubble years (2000 through 2004) that have not yet replaced one or more attemperators should consider themselves lucky, but not necessarily "in the clear." Insidious damage mechanisms may be at work, despite best inspection efforts. Plant managers must at least consider that possibility and plan accordingly. more 

Continuous-improvement mindset enables Klamath Cogen to better its award-winning ideas 

Iberdrola Renewables' Klamath Cogeneration facility, Klamath Falls, Ore, has been a mainstay of the CCJ Best Practices Awards program since its inception 10 years ago. CCJ editors got together on the phone with Ray Martens, plant manager; Tim Kelly, EH&S engineer; and Bruce Willard, operations and engineering manager, to elaborate on what's been happening since for half a dozen of the plant's award-winning best practices:

  • OSHA Voluntary Protection Program
  • ISO 14001 certification
  • Elimination of secondary-containment entry
  • Management-of-change program
  • Waste-stream reduction
  • Boiler-feed-pump VFDs  more  
Tests identify, track deterioration of a failing transformer

After installing a 4.12/7.5-kV, 3-phase, 11.2-MVA transformer in April 2012, Magna Electric Corp technicians, following company procedures, drew oil samples and ran dissolved gas analyses (DGA) before the unit was energized and about one week after it was energized. Normally, they would have conducted another series of tests about three months later. But, in this case, the early DGA tests indicated a potential problem and testing was done more frequently, Magna's Senior Utility Consultant Keith Burgess told attendees at the 2014 International Conference of Doble Clients. more
