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 ...
