Stator Core Flux Density Analytical Determination in Slotless Machines
Elloumi, Nada; Leandro, Matteo; Nøland, Jonas Kristiansen; Tessarolo, Alberto (Chapter, 2020)Slotless machines equipped with surface-mounted permanent magnet (SPM) rotor are used in such applications where the torque ripple and the additional losses due to the slotting effect are critical. For this kind of machine ... -
Stator Flux-Regulatory Excitation Control in Converter-Fed Synchronous Machines for Pumped-Storage Variable-Speed Hydropower
Stavnesli, Jørgen Hagset; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2022)Pumped-storage hydropower is seen as a promising solution for efficient, large-scale energy storage. One competitive technical solution is the variable-speed hydropower plant (VSHP) configured with a converter-fed synchronous ... -
Superconducting Multiphase Wind Power Generator
Tomé Robles, Dany Josué (Master thesis, 2021)En undersøkelse av AC-superledende spoler utføres med en permanentmagnetgenerator for en vindkraftturbin på 15 MW. To referansemodeller er dimensjonert: på den ene siden blir en DTU og NREL 15 MW vindturbinmodell tatt som ... -
Systemdrift 2020
Christoffersen, Fredrik Vigeland; Handeland, Tine; Grande, Tove Rømo; Nøland, Jonas Kristiansen; Øberg, Martha Marie; Ødegaard, Leiv Erik (Research report, 2012)KUBE 2012 har i årets sommerprosjekt svart på problemstillingen: Hvordan bør Statnett drifte kraftsystemet i 2020? Utviklingen av systemdriften frem mot 2020 vil drives av en kraftig økning i utvekslingskapasitet mot ... -
Thermal Mapping of the Hydrogenerator’s Reactive Power Boosting Ability at Various Time Windows
Robles, Dany Josue Tome; Nøland, Jonas Kristiansen; Maurer, Frédéric Michael; Øyvang, Thomas (Chapter, 2023)In the future, bulk power generation facilities like large hydropower plants need to be utilized more flexibly and provide extended services over shorter time intervals. This work presents a comprehensive thermal mapping ... -
Transient nonlinear Rayleigh-Bénard convection with single-mode initiation
Tyvand, Peder A.; Nøland, Jonas Kristiansen (Peer reviewed; Journal article, 2021)Transient nonlinear convection in a finite Prandtl number fluid heated uniformly from below is studied analytically and numerically. We consider the simple geometry of a square cavity with normal-mode compatible boundary ... -
Unified Reduced Model for a Dual Control Scheme of the High-Speed Response Brushless Excitation System of Synchronous Generators
Nøland, Jonas Kristiansen; Alves, Erick Fernando; Pardini, Atila; Lundin, Urban (Journal article; Peer reviewed, 2019)Developments of the high-speed response brushless excitation systems (HSRBESs) are ongoing in the power industry. This is because the transient response of the excitation system (ES) is a key performance indicator for the ...
