  1. 1. Stray capacitance study for HVDC Classic : The use of PSCAD and Mathcad to calculate the equivalent stray capacitance

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Saga Dalersand; Fredrik Gjöthlén; [2023]
    Nyckelord :;

    Sammanfattning : The reactors placed in the thyristor valve designed by Hitachi Energy have reactor losses which are dependent on the stray capacitance. To find out the stray capacitance, and further get to know the reactor losses, a PSCAD simulation is performed. LÄS MER

  3. 2. The Application of a TCSC Controller to Improve the Stability of a Power System With High Penetration of Renewable Energy

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

    Författare :Albin Wanhainen; Axel Gomér; [2023]
    Nyckelord :;

    Sammanfattning : The goal of this project is to examine how a higher penetration of power electronics-basedforms of power production affects system stability and damping. The project covers howpower system stability can be improved by using a Thyristor Controlled Series Capacitor(TCSC) with Power Oscillation Damping (POD). LÄS MER

  4. 3. Vibration analysis of a fast response brushless excitation system

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Emma Pålsson; [2019]
    Nyckelord :vibrations; frequency analysis; FRBE; controlled rectification; hydropower; exciter; generator; fast response;

    Sammanfattning : The aim of this study is to measure and analyze vibrations on a fast response brushless exciter (FRBE) at a real hydropower plant and identify vibration origins through frequency analysis. Moreover, the observed vibrations are evaluated in relation to generator vibration standards and estimated tangential eigenfrequencies of the studied FRBE. LÄS MER

  5. 4. Electronic Water Heater

    Magister-uppsats, Högskolan i Halmstad/Halmstad Embedded and Intelligent Systems Research (EIS)

    Författare :Rincy Valsalan; [2018]
    Nyckelord :;

    Sammanfattning : The main aim of my project is to develop a hardware implementation of the electronic waterheater by choosing different components and minimize the errors in the same. I have consideredseveral options depending on the availability of components, cost, reliability, implementation,financial budget, specification and thinking about the professional technical skills required.

  7. 5. A New Cell Bypass Arrangement and Control for Modular Multilevel Converters based on Thyristor Forced Commutation Circuit

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Soteris Poyiadjis; [2017]
    Nyckelord :;

    Sammanfattning : HVDC transmission lines are a competitive and in some cases are proven to bea superior choice compared to AC transmission applications. Suitable convertershave been developed for that matter where Modulär Multilevel Converters (MMC)are highly preferred due to their low losses, no filtering requirementsand direct andfast control of AC and DC side.
