PlantTriage now shows the impact that cyclic upsets have on your plant’s performance. PlantTriage’s new “Oscillation Significance” identifies cycling problems in a plant, and ranks them according to importance. Oscillatory upsets are always a problem. They cause energy losses, lower product quality, and reduced equipment life. Oscillation Significance uses a combination of statistical and frequency-domain information to calculate a single, meaningful measure of significance for each process parameter. Drill-down reporting ranks every process parameter in the plant by Oscillation Significance. John Gerry, President of ExperTune, says “Our customers have asked for more tools to make use of the enormous warehouse of information within PlantTriage. With Oscillation Significance, you can look at a single number and evaluate a very complex cycling problem.”John Gerry continued “Using traditional approaches, solving oscillation problems may take days or weeks. Now, in minutes, you can have a prioritized assessment of the cycling for every part of the process.”PlantTriage Oscillation Detection analyzes every process variable in a system, looking for patterns of cyclical behavior. It then identifies the source of oscillation to be valve problems, tuning, or load disturbances. Oscillation Significance further refines these assessments by using a combination of loop variability, oscillation detection, and percent of power by frequency. The resulting measure of oscillation detection can be ranked directly, or in combination with economic criteria. A list of process parameters ranked by oscillation significance is then displayed in a drill-down report.About ExperTune:For 19 years, ExperTune has created award-winning optimization software that runs in thousands of plants world-wide.
