Energibesparande åtgärder i en pumpprocess

This project involves analyzing if there are opportunities to make energy savings by finding the optimal operating point for the pumps and whether there are any other energy saving opportunities in the pumping process. This project is carried out for Tekniska Verken i Kiruna AB and included their va...

This project is carried out for Tekniska Verken i Kiruna AB and included their various facilities. Through tests for the various facilities the optimal speed for each pump was identified. This was carried out with help from the program Drive composer and with help from frequency converters. The results showed that the total savings that could be made by controlling the pumps towards the optimal speed was 9400 kWh per year. The significant savings opportunity for Tekniska Verken i Kiruna AB is to shift the operations to the time that is not covered by the peak period. With a change in operation of 20%, savings for 180 000 SEK per year can be made, while the load of the electricity grid from a large consumer is reduced during times when there are more users on the electricity grid. Investing in frequency converters for the pumps that don’t have one, is a profit from an energy saving perspective as well as from a financial perspective, where the payback period for this type of investment is calculated just over a year. This is applied to the purchase of frequency converters of the type found on the current pumps. Bachelor Thesis Kiruna Umeå University: Publications (DiVA) Kiruna
