Formation of micro-cracks at the surface of a high voltage cable screen induced by aluminum corrosion
(Chapter; Peer reviewed, 2023)The main purpose of this study is to investigate the adhesion between corroded aluminium conductor strands and the semi-conductive cable screen. In this paper it is proposed that increased adhesion is one of the pre-requisites ... -
Formulating the optimization problem when using sequential quadratic programming applied to a simple LNG process
(Journal article; Peer reviewed, 2015)Sequential quadratic programming (SQP) may be very efficient compared with other techniques for the optimization of simple processes for the liquefaction of natural gas (LNG), and can be combined with process evaluation ... -

Fourteen months operation of a 200 kWh latent heat storage pilot
(Chapter; Peer reviewed, 2023)A latent heat storage was in 2021 installed in an office building in Trondheim, Norway. The unit contains 3 tons of CrodaTherm 37, which is a bio-based wax phase-change material with a melting temperature of 37 degrees ... -
Fra forvaltning til forretning – Restrukturering av norske nettselskaper og konsekvenser for samfunnssikkerhet
(NTNU Samfunnsforskning. Rapport;, Research report, 2008)Samfunnets avhengighet av kritiske infrastrukturer som vann, elektrisitet og telekommunikasjon gjør oss sårbare for avbrudd i disse, noe som blant annet ble understreket i Willoch-utvalgets rapport ”Et sårbart samfunn”. ... -
Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model
(Journal article; Peer reviewed, 2016)Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO2 is transported. To overcome this, a coupled fluid-structure ... -
Framework and methodology for active distribution grid planning in Norway
(Chapter, 2020)The long-term planning frameworks currently used by electricity distribution grid companies are not designed to account for new challenges such as variable distributed generation or for new opportunities of active grid ... -

Frequency and Parameter Combined Tuning Method of LCC-LCC Compensated Resonant Converter with Wide Coupling Variation for EV Wireless Charger
(Peer reviewed; Journal article, 2021)The characteristics of inductive power transfer (IPT) systems are sensitive to the variation of the coupling coefficient caused by misalignment conditions or different gaps. This results in a reduction in transferred power ... -
Frequency Dependence of the Electric Field Grading of End-Winding of Generator Bars
(Peer reviewed; Journal article, 2022)To reduce the electric field stresses in the end-winding in hydropower generator bars, a field dependent grading tape is applied in the transition zone from outer corona protection to bare insulation. The design is typically ... -
Frequency Quality in the Nordic Power System: Wind Variability, Hydro Power Pump Storage and Usage of HVDC Links
(Peer reviewed; Journal article, 2013)This work investigates the effect that variable power production from offshore wind farms in the North Sea will have together with the use of pumped storage facilities at hydropower stations in Norway, on the Nordic ... -
Frequency-Adaptive Energy Control for Grid-Forming MMCs Under Unbalanced Conditions
(Peer reviewed; Journal article, 2023)This paper presents a frequency-adaptive energy control strategy for a Modular Multilevel Converter (MMC) which is suitable for grid-forming operation under unbalanced conditions. The average components of the energy sum ... -
Frequency-dependent cable modelling for small-signal stability analysis of VSC-HVDC systems
(Journal article; Peer reviewed, 2016)State-of-the-art time-domain models of power cables account for the frequency dependency of physical parameters to enable accurate transient simulations of high-voltage transmission schemes. Owing to their formulation, ... -
