    • 3D Numerical modeling of Sediment Deposition in a Hydropower Reservoir 

      Myhrvold, Halvor (Master thesis, 2016)
      The purpose of this assignment was to test and evaluate SSIIM 2 on its ability in numerical modelling of sediment transport in the hydropower reservoir Banjë in Albania, which is a 14 km long, and narrow hydropower reservoir. ...

    • DEBRIS HANDLING AT SMALL HYDRO POWER INTAKES 

      Holmeset, Fredrik (Master thesis, 2013)
      In this study the handling of debris in small hydro power intakes is assessed by evaluating the concept of back flushing with a horizontally fixed trash rack. The concept of back flushing is to reverse the flow over the ...

    • Design of Headworks in steep sediment loaded rivers: A model study case of Lower Manang Marsyangdi Hydropower Project 

      Dudhraj, Abha (Master thesis, 2013)
      Headworks design in steep, sediment loaded rivers is challenging. Technical challenges related to the functionalities of the headworks area have been studied for the case of Lower Manang Marsyangdi (LMM) Hydropower Project ...

    • Different Aspects of Flushing of Hydropower Intakes 

      Nielsen, Lars Eid; Rettedal, Bjørnar (Master thesis, 2012)
      Different design criteria for successful flushing of hydropower headworks have been evaluated. Main focus has been on handling of floating debris for small hydropower plant in Norway, as well as sediment handling for run ...

    • FUNKSJON TIL COANDAINNTAKSRISTER: ERFARING FRA DYRKORN KRAFTVERK 

      Opaker, Henrik (Master thesis, 2012)
      Hovedmålet med oppgaven er å dokumentere egnetheten til coandainntak i kaldt klima, og å studere og forklare tilfrysningsprosessen som skjer. Coandainntak er en type selvrensende overfallsinntak, hvor åpningen mellom ...

    • Impact of energy pricing regimes on production schedules under solar-hydro hybridization 

      Kong, Jiehong; Sheppard, Alexandra Jane; Nøvik, Hanne; Engelstad, Øyvind; Fjelldal, Bjørnar; Klæboe, Gro; Skjelbred, Hans Ivar (Chapter, 2023)
      Hybridization of complementary energy production increases system flexibility and allows optimization of energy and resource availability. Hydropower and floating solar photovoltaics (FPV) have a high potential for ...

    • Intake hydraulics for small hydropower plants 

      Nøvik, Hanne (Doctoral thesis at NTNU;2014:96, Doctoral thesis, 2014)
      The water intake structure at hydropower plants has the important function of providing clean water for safe and reliable power plant operation during all normal situations. This thesis deals with intake technologies for ...

    • New Techniques for Estimating Sediment Load for the Catchment of Banja HPP 

      Sørås, Sigurd (Master thesis, 2017)
      toring water in artificial reservoirs is a common method for ensuring constant water supply for among others irrigation, electricity and drinking water. The construction of such artificial storages will disturb the natural ...

    • Optimization of Hybrid Power Plant 

      Kristiansen, Vegard (Master thesis, 2023)
      Det har vært en betydelig utvikling av variabel fornybar energi de siste årene, og det forventes at denne utviklingen øker i fremtiden. I forbindelse med dette skiftet er det et økt behov for fleksible energisystemer, og ...

    • Physical Model Tests of Intake Design 

      Gotvassli, Ida Elisabeth (Master thesis, 2013)
      As there are no detailed guidelines on how to design culverts including sediments and debris, a laboratory model was made to find solutions to how sediments deposit in front of the culvert and how this affects the capacity. ...

    • Reducing ice accumulation on Coanda Screen intakes 

      Lia, Leif; Nøvik, Hanne; Alfredsen, Knut (Chapter, 2020)
      Coanda screen intakes has proved to be a reliable and cost-effective low maintenance solution for numerous small hydro (SHP) intakes in the past two decades. In Norway 50 intakes are installed since 2012, the first intake ...

    • Verifisering av inntakshydraulikk i grunt inntaksmagasin for småkraftverk med bruk av CFD-verktøy 

      Hasaas, Åsmund (Master thesis, 2012)
      I denne masteroppgaven har inntaksmagasinet til Juvfossen kraftverk, ved Stranda på Sunnmøre blitt modellert med CFD programmet STAR-CCM+. Modelleringen er gjort for å se om strømningsmønsteret i inntaksmagasinet kan ...
