Abstract [en]

Today paper is to find everywhere, and the production factories always need to increase the

productivity if they want to stay competitive. Stora Enso Kvarnsveden has one of the biggest

magazine paper machines in the world, which produces around 1900 meters of paper per

minute. The production process is highly automatized, which reduces the number of operators

that work on the machine. Still, process variations can cause brakes in the paper web and lead

to loss of income, energy and paper production. It may also have a direct impact on the paper

quality. This report is focusing the following question:

How to keep the Paper Machine production process under controlled conditions?

To make a data analysis fully relevant, we need to use the most important variables of the

machine. By analyzing these data some unexpected behavior and variation of process values

can be pointed out. The analyzing tool needs to be fast and portable, and therefore a software

system has been developed. By comparing process data with reference data this software can

make a powerful analysis.

The created software is intended to be used either by operators or engineers. The most

important results are collected in a file. In this text file, the comparison function gives the

results which are stored in a CSV-format. Furthermore, an auto-update function allows the

users to run it automatically. Graphical presentations are supporting the interpretation of the

results.
