Passivity-Based Control for Small Hydro-Power Generation with PMSG and VSC
(Peer reviewed; Journal article, 2020)This paper presents a passivity-based control method for a small hydro-power system that consists of a permanent magnet synchronous generator (PSMG) connected to the grid through a back-to-back converter. Nonlinear models ... -
Passivity-Based Control of Power Systems Considering Hydro-Turbine with Surge Tank
(Journal article; Peer reviewed, 2019)This paper proposes an interconnection and damping assignment passivity-based control (IDA-PBC) for multimachine power systems including hydro-turbine governing systems (HTGS) with surge tank. The main objective is to ... -
Pattern Recognition of Inter-Turn Short Circuit Fault in a Synchronous Generator using Magnetic Flux
(Journal article; Peer reviewed, 2021)This article provides a novel approach for discriminating the interturn short circuit (ITSC) fault in a salient pole synchronous generator (SPSG) based on the use of noninvasive sensors. A stray magnetic field is used as ... -
Pattern Recognition of Inter-Turn Short Circuit Fault in Wound Field Synchronous Generator via Stray Flux Monitoring
(Chapter, 2020)This paper provides a novel approach to discriminate the Inter-Turn Short Circuit fault (ITSC) in salient pole synchronous generator based on the use of non-invasive sensors. A stray magnetic field is used as a non-invasive ... -
Pålitelige skjermtilkoblinger i kraftkabler
(Master thesis, 2019)I de senere år har det oppstått flere omfattende og kostbare feil i det norske kraftnettet på grunn av lokal varmgang i kraftkabler. Hovedårsaken til dette er dårlig kontakt i skjermtilkoblinger ved skjøter og endeavslutninger. ... -
Pålitelighetsanalyser av forsyningsløsninger til kritiske belastninger
(Master thesis, 2011)I følge Forskrift om elektriske lavspenningsanlegg forutsettes det, i sammenheng med valg av løsning for elektriske anlegg, at risiko vurderes og det er presisert at dette også innebærer at anlegget skal ha tilfredsstillende ... -
PD-Activity in Generator Stator Bar insulation versus Voltage Frequency and Temperature
(Chapter, 2020)Condition assessment of generators is today performed at various voltage frequencies and test temperatures. The main purpose of this paper is to compare measured PD results from sections of generator bars with that of ... -
PD-testing av høytemperatur motorkabel
(Master thesis, 2017)Det er viktig å få testet kabler for partielle utladninger (PD), da partielle utladninger over tid kan skade kabelen og føre til gjennomslag. Hovedfokuset i denne masteroppgaven har vært å PD-teste motorkabler uten ytre ... -
Peaked sloshing in a wedge container
(Peer reviewed; Journal article, 2021)Finite-amplitude free-surface flow in a wedge container is investigated analytically. We study a motionless standing wave of pure potential-flow acceleration with maximal amplitude where its right-angle surface peak falls ... -
Pedagogisk forbedring av undervisningen på NTNU med emnet Elektriske kraftsystemer som eksempel
(Master thesis, 2019)I denne masteroppgaven sees det på hvordan undervisningen av emner på NTNU kan forbedres. Oppgaven beskriver ulike aktive læringsformer og pedagogiske prinsipper som Konstruktiv justering og relasjon, og viser hvordan disse ... -
Peer-to-Peer electricity trading in an Industrial site: Value of buildings flexibility on peak load reduction
(Peer reviewed; Journal article, 2021)Local electricity markets and peer-to-peer (P2P) trading schemes in buildings have recently gained importance as an efficient way to incentivize energy flexibility (e.g. consumer demand response or storage) and to share ... -
Peer-to-Peer Energy Trading in Combination with Local Flexibility Resources in a Norwegian Industrial Site
(Master thesis, 2019)Med den økende utrullingen av desentraliserte fornybare energikilder og energikrevende enheter møter dagens kraftsystem nye utfordringer. Som et behov for fleksible alternativer på lokalt nivå. Det betyr at kraftsystemets ... -
Peer-to-peer trading under subscribed capacity tariffs - an equilibrium approach
(Chapter, 2020)Local peer-to-peer (P2P) markets are envisioned as a promising market design to integrate the increasing number of agents in the distribution grid. To incentivize grid-friendly consumption profiles, we suggest a subscribed ... -
Perception, Prediction and Prevention of Extraordinary Events in the Power System
(Doctoral thesis at NTNU;2016:10, Doctoral thesis, 2016)Conventional risk and reliability assessment techniques are insufficient when it comes to analysing extraordinary events on-line. The reason for this lies in the nature of extraordinary events, which are the result of ... -
