1. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The modern power system is aiming to progress away from conventional synchronous machine based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).

2. Insulation diagnostics of stator bars
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Insulation in rotating machines is a common cause for failure. Therefore, research in the area is large and is important to further increase the knowledge of the phenomena related to insulation degradation. LÄS MER
3. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. LÄS MER
4. Jordning av propelleraxel : Konceptutveckling för jordningsanordning som kräver lite underhåll
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Detta masterprojekt genomfördes på Rolls-Royce AB (nu känt som Kongsberg Maritime per 1 april 2019) i Kristinehamn, Sverige. Avhandlingen fokuserar på att utveckla en jordningsutrustning för propelleraxlar som kräver lågt underhåll till företagets nya poddrivna framdrivningssystem. LÄS MER
5. Implementing VLF as diagnostic test for HV motors and generators : A comparative study of diagnostic tests performed at different frequencies
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : High voltage testing of the stator winding insulation is one of the most recognized methods used to determine the state of degradation in the insulation. HV tests performed at 0.1 Hz do have potential advantages compared to more traditional 50 Hz tests. LÄS MER
