1. Design and Simulation of a Slotless Aircored PM Synchronous Generator
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : This thesis is a study on an unconventional slow speed direct drive permanent magnet (PM) generator. Unlike a standard permanent magnet synchronous generator (PMSG) which has the copper coils wound around iron teeth, the work in this thesis will present a generator where the copper coils are directly mounted on the stator which eliminates the slots and teeth in the generator.

2. Stability Related Issues for High Wind Power Penetration : Exploring possibilities to enhance grid stability from synthetic inertia in a future scenario
Magister-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : The future global energy transition favour renewables such as wind power, which is predicted to be one of the predominant sources harvesting abundant amounts of energy onwards. Consequently, causing several conventional synchronous generators to be decommissioned in a near future to achieve an overall reduction in greenhouse gases related to electricity generation. LÄS MER
3. Comparison between active and passive rectification for different types of permanent magnet synchronous machines
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : When using an intermittent source of energy such as wind power together with a synchronous machine a frequency converter system is needed to decouple the generator from the grid, due to the fluctuations in wind speed resulting in fluctuating electrical frequency. The aim of this master's thesis is to investigate how different types of rectification methods affect permanent magnet synchronous machines of different saliency ratios. LÄS MER
4. Simulations of vertical axis wind turbines with PMSG and diode rectification to a mutual DC-bus
Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaperSammanfattning : Transient simulations were performed with MATLAB Simulink on a mutual wind park topology, where three vertical axis wind turbines equipped with permanent magnet synchronous generators were connected to a mutual DC-bus through passive diode rectification. The aim with the work was to show the effects of two different kinds of loads on the system in respect to generator torque, rotor speed, produced power by the generators and the power on the DC-bus.
