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

   University essay from KTH/Skolan för industriell teknik och management (ITM)

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

   Abstract : 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. READ MORE

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

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Abstract : 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. READ MORE

   Keywords : Digital Twin; Bayesian Optimiation;

   Abstract : 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. READ MORE

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

   University essay from KTH/Skolan för industriell teknik och management (ITM)

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

   Abstract : 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. READ MORE

6. 5. Effect of Surface roughness for Hydro Turbine Step-up Efficiency

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ermias Beraki; [2018]
   Keywords : Hydropower; Surface roughness; Hydro Turbine; Step-up Efficiency; IEC 62097 standard; Prototype and Model;

   Abstract : The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. READ MORE
