Routine Trend Analysis Program for Plant Process Parameters

Abstract

Trend Analysis is the review of organized presentations of process parameter data over time for the purpose of understanding process control response to unplanned transients or system performance during normal operation. The concept of establishing a formal Trend Analysis Program for critical parameters of key process systems during normal operation is reviewed. Improved plant efficiency, reduced calibrations, potential avoidance of process transients, and the establishment of a more knowledgeable and responsive staff are all benefits from such a program. Easy access to personal computers and the availability of good analytical data base software have made this good practice a more viable and timely option for use by station staff as a predictive maintenance tool.
