  1. 6. Development of a Real-Time Simulation Model in RSCAD of a STATCOM and its Control System

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Jessica Redander; Johanna Lenárd; [2021]
    Nyckelord :STATCOM; FACTS; Grid Forming; Control System; Modular Multilevel Converter; Voltage Source Converter; Power System; RSCAD; RTDS;

    Sammanfattning : The development of interconnected power systems together with an increasing number of renewable non-synchronous power sources, create major challenges for the power system to meet the voltage stability and power quality requirements. One way to increase the voltage stability in a sustainable way is to locally implement a STATCOM. LÄS MER

  3. 7. A Comparison of Grid-Forming and Grid-Following Control of VSCs

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pontus Roos; [2020]
    Nyckelord :Voltage source converter; Synthetic inertia; Fast frequency response; Power system; STATCOM; Energy storage; Power electronics; Syntetisk svängmassa; Frekvensreglering; Elkraftsystem; energilager; kraftelektronik;

    Sammanfattning : Variable renewable energy sources are today increasingly integrated in the power system as a step towards the renewable society. The large-scale introduction of converter-based energy sources brings challenges in terms of reduced damping to the power system due to the reduced number of synchronous generators. LÄS MER

  4. 8. Fault current injection from power electronic interfaced devices

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

    Författare :Sandra Thengius; [2020]
    Nyckelord :;

    Sammanfattning : An increasing number of synchronous generators being replaced by renewable energy sources (RES) and HVDC links is expected in the future. HVDC links, some fast-growing renewable energy sources (RES) such as wind and solar photovoltaics, and system controllers such as STATCOM, have power- electronic interfaces to the grid. LÄS MER

  5. 9. Predictive Maintenance of DC Capacitors in STATCOMs

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Rasmus Söderström; [2020]
    Nyckelord :Predictive Maintenance; STATCOM;

    Sammanfattning : To further improve the reliability of STATCOM solutions a predictive maintenance system can give the user valuable readings of capacitor health an online and non-invasive, and especially readings of individual capacitors. This allows the user to replace individual deteriorating capacitor links in an MMC configuration before triggering any safety system. LÄS MER

  7. 10. Automated regression testing in Power Grids applications

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Elektricitetslära

    Författare :Kristian Flodström; Andersson Simon; [2019]
    Nyckelord :Regression testing; power grid; statcom; svc;

    Sammanfattning : During development of any kind, the testing process is a big part in terms of time and money. Automating the testing procedure to run regression tests more frequent and in an effective manner makes the development phase a simpler and more development focused activity. LÄS MER
