  1. 1. Evaluation of OPAL-RT Simulator through Simulation of Microgrid with High Penetration of DER

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Anton Grönberg; [2024]
    Nyckelord :Real-Time simulation; Power System Simulation; OPAL; DER;

    Sammanfattning : This thesis was written in collaboration with the department of electrical engineering at Uppsala University. It evaluates and tests the potentials and limitations of using the OPAL-RT simulator as a tool for designing and developing control strategies used in microgrids with a high penetration of distributed energy resources.

  3. 2. State of Health measuring of NiMH batteries using simple electronic components.

    Kandidat-uppsats, Linköpings universitet/Fordonssystem

    Författare :Linus Classon; [2024]
    Nyckelord :SoH; NiMH; State of Health; Batteries;

    Sammanfattning : The possibility of measuring the state of health of a NiMH battery without doing it in a lab is evaluated, the goal was to see if it was possible to perceive any differences between batteries of different states of health and whether it’s worth further exploring this solution in a more detailed manner. In order to try and extract and analyze the state of health of the batteries a series of tests consisting of discharging batteries at different lengths of times and different resistive loads were made, the voltage of the batteries being captured by a multimeter.

  4. 3. Eine empirische Untersuchung des Sprachengebrauchs im schwedischen DaF-Unterricht : Unterrichtspraxis und Einstellungen von Lehrenden und Lernenden

    Kandidat-uppsats, Stockholms universitet/Tyska

    Författare :Mikaela Rydén; [2024]
    Nyckelord :German; Fremdsprachenunterricht; Zielsprache; Ausgangssprache; Fremdsprache; Mehrsprachigkeit; Schwedisch; Deutsch; DaF-Unterricht; Einstellungen; Code-Switching; Sprachengebrauch; Einsprachigkeit; tyska; moderna språk; målspråksanvändning;

    Sammanfattning : This study aims to investigate when and how much German as well as Swedish is spoken by teachers and pupils in two high school classes. On top of that, the study includes both the teachers´and pupils´attitudes towards the usage of the languages in their German lessons. LÄS MER

  5. 4. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Weideskog; [2024]
    Nyckelord :FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Sammanfattning : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. LÄS MER

  7. 5. WEARABLE STORAGE

    Kandidat-uppsats, Lunds universitet/Industridesign

    Författare :Benjamin Redin; [2024]
    Nyckelord :Arts and Architecture; Technology and Engineering;

    Sammanfattning : This project is about challenging the traditional concept of a backpack. They tend to be designed around the carrying of objects, moving them comfortably on the body from A to B. This product focuses on the stationary use when the collection of objects are next to the user and when they take things. LÄS MER
