Thorstensson, Anton, 2020. Energieffektivisering av dricksvattendistribution : dataanalys och simulering av pumpdrift vid Görvälns vattenverk. Second cycle, A1N, A1F or AXX ( A1N). Uppsala: SLU, Dept. of Energy and Technology



This project investigates the efficiency of the water distribution system from Görväln's pumping station to Norrvatten's central consumption zone. The goal is to propose actions that lead to enhanced energy efficiency. The project evaluates the operation of the pumps that transport the drinking water, and simulates the distribution with a focus on Tunberget's high reservoir. The analysis is done using a dense dataset of measurement from pressure, flow and level sensors in the system. First, the pumps have been analyzed individually as far as possible. Further, all possible combinations of the six pumps used are also analyzed. The modeling of the system is done in MatLab Simulink and adjusted to the empirical conditions that apply to the real system. The project also investigates the possibilities of create consumption forecasts with machine learning algorithms and using these to improve the distribution system. The results shows that there exists a potential for energy efficiency. The greatest potential is found in the pump operation and in the choice of favorable pump combinations. The implementation of consumption forecasts increases delivery security but also reduce energy consumption to a certain extent. The total energy efficiency improvement is estimated at 257 MWh annually, corresponding to 2.4 % of the water pumps' total energy consumption in 2019.
