1. Visionen om elintensiva industrier i Norrbottens län : Hur påverkade Porjus vattenkraftverk den industriella utvecklingen i Norrbottens län mellan år 1915–1938?
Kandidat-uppsats, Uppsala universitet/Ekonomisk-historiska institutionenSammanfattning : Studien undersöker hur Porjus vattenkraftverk påverkade den industriella utvecklingen i Norrbottens län mellan 1915–1938. Syftet med uppsatsen var att undersöka om elintensiva industrier etablerades efter vattenkraftverkets invigning samt hur industristrukturen i Norrbottens län påverkades under perioden 1915–1938.

2. Operation Oriented Digital Twin of Hydro Test Rig
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : It has become increasingly important to introduce the Digital Twin in additive manufacturing as it is perceived as a promising step forward in its development and a vital component of Industry 4.0. Digital Twin is an up-to-date representation of a real asset in operation. The aim of this thesis is to develop a Digital Twin of a hydro test rig. LÄS MER
3. Porjus Energy Village
Uppsats för yrkesexamina på avancerad nivå, KTH/ArkitekturSammanfattning : My project attempts to nuance the bodies of knowledge produced in relation to processes of natural resource extraction in Norrbotten, Sweden. Operating between fact and fiction, I have presented the project as a speculative video narrative. The protagonist is the Lule River, where the implications of its domestication and agency is explored. LÄS MER
4. Numerical simulations of the pressure time method in a full-scale turbine
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Efficiency measurements are an important part of operating and maintaining a hydroelectric turbine. In order to calculate the efficiency, one need a method to accurately measure the flow rate. The pressure time method is a way to calculate the flow rate from pressure measurements, which are done during a transient. LÄS MER
5. Preliminary simulation of Porjus U9 turbine at speed no load
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Hydropower plants are shifting towards operating at off-designed conditions, meaning that the number of start-stop cycles and maintenance time due to cavitation increases. The speed no-load condition is the moment before magnetization of the generator, i.e., no load, low flow, constant runner rotational speed, guide vane and runner blade angle. LÄS MER
