Data processing of process control data, involves filtering out or allowing for erroneous input data in data consolidation phase, an example being data processing during bringing of heat exchange plant on or off line

摘要

A method for preparation of a data set (D) from a number of output values (Ai) representing measurement parameters that are subjected to a number of preset boundary conditions. Data consolidation is achieved that strictly observes the boundary conditions. Test data is produced from measurement data and random data and is processed as normal. A filter criterion is applied to final data sets. An independent claim is made for a system for processing data sets that ensures that boundary conditions and tolerance levels are adhered to.
