DC Tangential Electric Breakdown Strength of Silicone Rubber Interfaces under dry, wet and oily conditions
(Master thesis, 2016)This research work is a part of an on-going project at NTNU/SINTEF-Energy Research aim- ing at developing new criteria for design of compact high voltage subsea connectors. Most high voltage insulation systems consists of ... -
Energy Flexibility in Power Systems - Challenges and Possibilities
(Master thesis, 2016)In 2010, owing to reduce carbon dioxide emissions, and furthermore to improve the energy efficiency, the European Council aimed at reducing 20% of Union s energy consumption by 2020. In that way, a large deployment of ... -
Håndtering av endrede jordfeilegenskaper i 22kV distribusjonsnett - Med fokus på deteksjon og vern
(Master thesis, 2017)Jordfeilvern er en viktig del av distribusjonsnettet da jordfeil er den mest utbredte feilen på dette nettnivået. En jordfeil i distribusjonsnettet vil berøre sluttbrukerne i stor grad og i et stadig mer energikrevende ... -
Inductor Design for Filter Applications with high dV/dt
(Master thesis, 2016)The work in this report has consisted in the design of three different inductors to verify how conductor profile impact stray capacitance, and how stray capacitance impact filtering performance. The three conductor ... -
Methodology for Detecting and Interpreting Instantaneous Frequencies in Stand-alone Microgrids - An Application of the Hilbert Huang Transform on Electrical Networks
(Master thesis, 2017)Following the tile, this thesis seeks to find a methodology for detecting and interpreting instantaneous frequencies in stand-alone microgrids. This is not a novel exercise for scientists to do but it bears potential to ... -
Mitigation of Subsynchronous Resonance with Thyristor Controlled Series Compensation in the Great Britain Power Network
(Master thesis, 2016)In this thesis, the use of thyristor controlled series compensation are studied as a tool to mitigate resonance between the mechanical and electrical part of a series compensated Great Britain power network. A literature ... -
Nettsentralens praksis og forbedringspotensial i TrønderEnergi
(Master thesis, 2016)Norges kraftnett er i dag driftet av mange små og store nettselskaper, som hver for seg har som mål å ha høy driftssikkerhet i sitt kraftnett. I denne rapporten blir det sett spesielt på nettselskapet TrønderEnergi, der ... -
Online Voltage Stability Monitoring in Distribution Networks
(Master thesis, 2017)Power systems are often operated close to their stability limit. Line contingencies or other disturbances can cause the system to lose stability. If the power system loses stability counteractions have to be taken or else ... -
Optimal use of resource flexibility in distribution systems
(Master thesis, 2017)To cope with the increasing share of dispatchable renewable energy sources, the consumer needs to evolve from being a regular passive consumer, to being a prosumer. The prosumer produces energy through residential solar ... -
