Instrumentation Issues

Welcome back! It’s been a while since I’ve posted here. Been buried with client requests… there are worse problems to have, I suppose.

This summer’s focus is INSTRUMENTATION.

I’ll be digging into the instrumentation requirements for combined cycle facilities, looking at what instrumentation you’re likely to have on site, what accuracy and uncertainty you can expect for your key performance indicators (such as GT compressor efficiency, ST sectional efficiencies and overall plant net heat rate), and the cost to add instrumentation – especially those items you very likely don’t currently have (such as an accurate weather station or gas chromatograph).

So… please post any suggestions, comments or questions regarding instrumentation here on this blog entry, or jot me an email direct.

I’d love to hear from you about what your current issues are regarding instrumentation:
* How often do you calibrate devices not required by controls?
* What manual inputs do you make (or try to make) on a regular basis? (i.e. HHV)
* What roadblocks do you run into when trying to add instrumentation?

And check back here for updates. Hopefully more often than once a year!
I hope you all enjoy your summer.
-Tina
