  1. 1. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

  3. 2. Development of an investment model for pumped storage hydropower

    University essay from Uppsala universitet/Elektricitetslära

    Author : Pontus Gustavsson; Eric Swanmark; [2023]
    Keywords : pumped storage hydropower; investment models; energy storage; grid balancing;

    Abstract : The energy market is evolving, with a prediction of heavily increased consumption and, consequently, increased production. In parallel, EU directives with targets prioritising fossil-free electricity production, reduction of greenhouse gas emissions and becoming climate neutral by 2050, poses a challenge for the current state of electricity production in the Nordics.

  4. 3. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilía Sól Gudgeirsdóttir; [2023]
    Keywords : SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Abstract : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. READ MORE

  5. 4. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eddie Blomström; [2022]
    Keywords : fishway; flow; hydraulics; HEC-RAS;

    Abstract : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. READ MORE

  6. 5. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

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

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE
