  1. 6. Design changes to simplify maintenance and condition assessment on a tap changer

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Arvid Fermér; Jakob Modling; [2023]
    Keywords : Power transformer; Chemical degradation; Electrical insulation; Tap changer; Insulation Electrical; Transformer insulation; Insulating oil; Insulation condition assessment; Transformer; Power grids; Power distribution; Oil filled transformer; Transformer oil;

    Abstract : This master thesis investigates a redesign for a maintenance tube, used for both sampling and draining transformer oil from a tap changer compartment. With the current design, one can do one or the other of sampling and draining. READ MORE

  3. 7. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fan Yang; [2023]
    Keywords : Converter Design; Dual Active Bridge; Single Phase Shift Modulation; Extended Phase Shift Modulation; Efficiency Estimation; Konverterdesign; Dual Active Bridge; Single Fas Shift Modulation; Extended Phase Shift Modulation; Effektivitetsuppskattning;

    Abstract : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. READ MORE

  4. 8. Microgrid Protection Strategies for the Swedish Power System

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Zalak Shah; [2023]
    Keywords : Microgrid; Protection; three-phase fault; earth fault; Technology and Engineering;

    Abstract : This thesis mainly focuses on the protection strategies of microgrids for the Swedish power system in the medium voltage distribution system and specifically on the three-phase fault and earth faults protection strategies. For the analysis of both faults, different grid-connected, and islanding operations are simulated using DIgSILENT Power Factory. READ MORE

  5. 9. Application of transfer learning in text classification for small and medium sized web-based enterprises

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Victor Oldensand; Simon Haglund; [2022]
    Keywords : ;

    Abstract : In recent years, the open sourcing of pretrained machine learning models through platforms like Hugging Face has reduced the barriers to entry in big data analysis. This thesis studies the use case of such models for web-based organisations, with a focus on text classification. READ MORE

  6. 10. Magnetic and Dielectric Design of Auxiliary Power Supply for HVDC Applications : A high-frequency transformer with high power transfer capability and high voltage electrical insulation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Johansson; [2022]
    Keywords : Auxiliary Power Supply; HVDC; Inductive Power Supply; High Voltage Insulation; High-Frequency Transformer; Hjälpkraftsförsörjning; HVDC; Induktiv Kraftförsörjning; Högspänningsisolation; Högfrekvenstransformator;

    Abstract : It is anticipated that massive amounts of energy will be transferred long distances via High-Voltage Direct Current (HVDC) links in the future and the prospect of having meshed HVDC grids is envisioned, for example the European super grid. Such a power system would benefit greatly if HVDC circuit breakers could reliably clear faults within the HVDC network. READ MORE
