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. Investigation of Variable Speed Technology when Converting Hydropower Kaplan Turbines into Fixed Propeller Turbines

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Johannes Ansved; [2022]
   Keywords : hydropower; variable speed; kaplan; turbines; model; simulation;

   Abstract : With an evolving energy system, an increased flexibility is necessary, placing additional demand on hydropower plants. New technology, in particular full size frequency converters (FSFC) and doubly fed induction machines (DFIM), allows hydropower turbines to run at different speeds than originally designed, thus making the turbine more flexible.

4. 3. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

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

   Author : Emil Treitler; [2022]
   Keywords : Fatigue; Kaplan; Hydropower; Turbine;

   Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

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

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Ali Khademi; [2022]
   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

6. 5. Optimization of Kaplan turbines for frequency regulation in hybrid hydropower plants

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Nayan Narkhede; [2022]
   Keywords : Kaplan; Kaplan turbines; frequency regulation; hybrid hydropower plants; wear and tear; guide vanes; runner blades;

   Abstract : The increasing penetration of variable renewable energy sources in the Nordic Power System is causing frequency quality degradation and has increased the importance of primary frequency control provided by hydropower plants. Hydropower is the world’s largest renewable energy source.
