When you operate multiple assets such as boilers, pumps or compressors in tandem some unusual control problems arise. This paper describes some of those issues and offers clues on how best to operate assets in tandem.
When there are a multitude of control loops interacting on each other it can be difficult to ascertain the exact correlations between the loops. ProtunerPlus has a suite of powerful Time Series Analysis tools to help you gain an accurate assessment of the dominant loops in your process. In this paper one of our affiliate partners, Dave Ender, gives an excellent example of the use of cross and auto correlation.
There are so many myths and fallacies surrounding the tuning of control loops that it is hard to understand the truth. However one inexorable link can always be made between the dynamics of the process and the correct tuning parameters. In this paper another one of our affiliates, Mike Brown, explores one of the great myths about dealing with deadtime dominant processes.
Measuring electricity consumption is a critical component of managing your energy usage But the difference between measuring for energy management or billing purposes can have a profound impact on the cost of the meter that you purchase. In this paper Dennis Henry from Ceta Meters Australia explains what pattern approved meters are and when they must be used and when a non-pattern approved meter will meet your requirements.
