1. 1. Pilot Study: Test Rig for Self-lubricating Kaplan Runner Bearings

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Bhairav Khadke; [2023]
   Nyckelord :Hydropower; Kaplan turbine; Self-lubricating bearing Test rig. Hydropower; Kaplan turbine; Self-lubricating bearing Test rig.; Vattenkraft; Kaplanturbin; Självsmörjande lager Testrigg.;

   Sammanfattning : Hydropower has a relatively small impact on the climate and contributes to almost half of Sweden’s electricity production. Vattenfall own and operate roughly 125 large scale hydro power units of which about half utilizes a Kaplan turbine. LÄS MER

3. 2. Fish Friendly Turbines forDownstream Migration : Literature review and case studies

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Signe Rosenblad; [2023]
   Nyckelord :Downstream passage solutions; downstream migration of fish; small-scale hydropower; eel; trout; Nedströms passagelösningar; nedströms vandring av fisk; småskalig vattenkraft; ål; öring;

   Sammanfattning : As the energy consumption is constantly increasing, the demand of renewable energy is increasing too. Thirtythree percent of the renewable energy production in Europe constitutes of hydropower. Hydropower is animportant energy source as it has stabilizing and storing functions, but it heavily affects biodiversity. LÄS MER

4. 3. Operation Oriented Digital Twin of Hydro Test Rig

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Ali Khademi; [2022]
   Nyckelord :Digital Twin; Bayesian Optimiation;

   Sammanfattning : 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

5. 4. Analysis of uncertainties in fatigue load assessment : a study on one Kaplan hydro turbine during start operation

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Annica Gustafsson; [2019]
   Nyckelord :Hydropower; Hydro turbine runner; Uncertainty analysis; Fatigue load; Fatigue damage; Propagation of uncertainty.; Vattenkraft; Löphjul; Osäkerhetsanalys; Utmattning; Delskada; Fortplantning av osäkeheter.;

   Sammanfattning : In the future, hydropower plants are expected to operate more flexibly. This will lead to a more varied operation of the turbine and the generator, such as more start and stop in order to stabilise the frequency in the grid. Studies show that these transient operations are more costly in terms of fatigue degradation, i.e. LÄS MER

7. 5. Anpassning av småskaliga vattenkraftverk för ö-drift av lokalt elnät

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Jonatan Fredriksson; [2019]
   Nyckelord :small hydropower; hydropower; Kaplan; turbine; transient; disturbance; resilliance; power grid; island; islanding; adapting; island mode; frequency control; dummy load; Kaplan; Kaplanturbin; elnät; ö-nät; ö-drift; vattenkraft; småskaliga vattenkraftverk; transient störningstålighet; indexprov; kombineringsprov; lokalt elnät;

   Sammanfattning : This master thesis examines technical requirements for small hydro power plants (HPP) to operate proximate parts of the power grid in island mode. The work examines how small hydropower can be modified and complemented with additional technologies to achieve sufficient frequency control capabilities. LÄS MER
