Utveckling av energiövervakningssystem med Production Discovery som grund

Sammanfattning: The goal of this thesis project was to develop an energy surveillance system for the Swedish production industry. The main problem this project sought to solve is that several Swedish industries are currently only able to measure the energy consumption of their entire facilities, as one big black box. They cannot determine the energy consumption of the individual machines within each and every production site. This makes it difficult to discover if any machine consumes more energy than it should. The goal of this project has therefore been to develop a system that allows the user to determine the energy consumption of all the individual parts of a production site. The project has been conducted at the company itAutomation in Malmö and is based on their product Production Discovery. The original goal was to develop a general concept for energy surveillance, which could be adapted to each customer's individual needs. However this changed halfway through the project as itAutomation received an order from AAK, a company with a production facility in Karlshamn, and the course of this thesis project changed thereafter. The aim of the project was changed from developing a general concept, to developing an energy surveillance system specifically designed for AAK’s facility. A significant amount of information for the development of a general energy surveillance concept was found during the work, such as which type of PLC would be suitable for this sort of system, which KPI-values (Key Performance Indicators) most production companies will be interested in as well as which meters and communication protocols are common within the Swedish production industry. The product for AAK was however not possible to complete, due to a faulty connection between the database Proficy Historian and the diagram tool Qlik Sense. This was such a major problem that the system as a whole did not work without them, as the two components were essential to the entire concept.
