• Dynamic Behavior of Reversible Pump-Turbines in Turbine Mode of Operation 

      Walseth, Eve Cathrin (Doctoral theses at NTNU;2016:202, Doctoral thesis, 2016)
      Reversible pump-turbines, with their steep and s-shaped characteristics, have proven throughout history to be a challenge with regards to both stability and transients. The aim of this thesis is to increase our understanding ...
    • Frekvensresponsmålinger ved Svartisen Kraftverk 

      Høigaard, Morten (Master thesis, 2010)
      Mål Simulere Svartisen Kraftverk i LVTrans og sammenligne med frekvensresponsmålinger. Oppgaven skal bearbeides utifra følgende punkter: 1) Kandidaten skal sette seg in i teorien bak og metoder for frekvens respons målinger ...
    • Investigation of the Flow through the Runner of a Cross-Flow Turbine 

      Walseth, Eve Cathrin (Master thesis, 2009)
      The cross-flow turbine is unique due to the generation of power during two stages. The water flows through the rectangular cross-section nozzle and enters the runner, where the first stage power is generated. The water ...
    • Measuring the dynamic characteristics of a low specific speed pump-Turbine model 

      Walseth, Eve Cathrin; Nielsen, Torbjørn Kristian; Svingen, Bjørnar (Journal article; Peer reviewed, 2016)
      This paper presents results from an experiment performed to obtain the dynamic characteristics of a reversible pump-turbine model. The characteristics were measured in an open loop system where the turbine initially was ...
