Håkon Sundt

Defended in 2022

Remotely sensed data for bathymetric mapping and ecohydraulics modelling in rivers

Through his PhD, Håkon Sundt has looked at the use of remote sensing as a source of information on bathymetry, seasonal mesohabitats for fish, scenarios for mitigation measures and strategies for environmental eDNA sampling.

Andreas Kleiven

Defended in 2022

Decision analytics in hydropower: Investment and operational planning under uncertainty

The rapid development towards a more sustainable power system gives rise to complex stochastic optimization problems for hydropower producers. In his thesis, Andreas Kleiven has worked on developing optimization models and methods for sustainable investment and operation of hydropower plants.

Bibek Neupane

Defended in 2021

Long-term impact on unlined tunnels of hydropower plants due to frequent start/stop sequences

In his thesis, Bibek Neupane has tried to better understand how the long-term stability of unlined water tunnels is affected by frequent pressure pulsations due to repeated start/stop sequences.

Henki Ødegaard

Defended in 2021

Rock Stress Estimation for Unlined Pressure Tunnel Design

Henki Ødegaard has looked at new methods for estimating the rock stress which hydropower tunnels are exposed to during the current operation of hydropower plants. Through his PhD he has worked on a new test protocol that can function as a faster alternative for calculating rock stress.

Tor Inge Reigstad

Defended in 2021

Optimal control of variable speed hydropower

As the share of wind and solar energy production increases, more flexible production and loads are required to control the balance of the grid. In his Thesis, Tor Inge Reigstad proposes a new control method for optimal control of hydropower plants with variable speed.

Kristian Sagmo

Defended in 2021

Trailing edge vortex shedding in hydraulic turbines and the effect of stream-wise vorticity on vortex induced vibrations

Experiments as well as some numerical simulations were conducted investigating the resonance region of vortex induced vibrations for different trailing edges of a hydrofoil in channel flow. The study focuses on the usefulness of stream-wise vorticity for the mitigation of vortex induced vibrations for the different trailing edge geometries.

Lena Selen

Defended in 2020

Assessment on the swelling and disintegration potential of weak and weathered rocks in water tunnels of hydropower projects - a contribution based on use of laboratory testing methods

During her PhD, Selen worked on testing the methods for measuring the stability of rock materials in the hydropower plants' "main artery", the tunnels.

Igor Iliev

Defended in 2020

Francis turbines for variable speed operation

In his PhD project, Iliev has designed a total of 421(!) turbines, and has by using numerical models found the design that is best for running with variable speed.

Erlend Løklingholm Engevik

Defended in 2019

Design and Operation Investigations for large Converter-Fed Synchronous Machines in Hydropower Applications

In his PhD, Erlend L. Engevik has used numerical models to investigate the design of synchronous machines, and looked at ways to optimize the design.

Bjørn Winther Solemslie

Defended in 2016

Experimental methods and design of a Pelton bucket

In his PhD, Solemslie has looked at and developed a publicly available methodology on Pelton turbine geometry and design. He has also produced quantifiable current measurements of the current in the turbine and studied these.
