  1. 1. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Leonardo Alvarez Urrutia; [2022]
    Nyckelord :Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

    Sammanfattning : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. LÄS MER

  3. 2. Small Signal Stability of Power Systems With Increased Converter Based Power Production

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

    Författare :Gustav Kjellson; Josefin Gustafsson; [2022]
    Nyckelord :Small signal stability; Power system stabilizer; Renewable energy; Grid following converters; Grid forming converters;

    Sammanfattning : The aim of this project is to analyze how increasing the share of converter-based power production in a power system affects the small signal stability. The project also aims to stabilize systems using Power System Stabilizers (PSSs), and examine the effect of two different types of power electronic converters: grid following (GFL) and grid forming (GFM).

  4. 3. Tuning of Power System Stabilizers to Damp Out Power Oscillations

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

    Författare :Joel Viil; Marcus Seisay; [2021]
    Nyckelord :Power System Stabilizer; Critical Generator; Small Signal Instability; Terminal Voltage; Field Voltage; Frequency;

    Sammanfattning : With the rise of global sustainability energy initiatives,the implementation of renewable energy sources infuture electrical grids is increasing. Many of the renewableenergy sources are however intermittent, meaning they providevarying levels of power. LÄS MER

  5. 4. Excitation system – simulation, tuning and evaluation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Philip von Heideken; [2021]
    Nyckelord :;

    Sammanfattning : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.

  7. 5. Implementering av en PSS i Trängslets kraftstation

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

    Författare :Lars Ilis; [2013]
    Nyckelord :PSS; kraftsystemstabilisator; kraftsystemstabilitet; rotorpendling; rotoroscillation; Trängslet; kraftstation; ;

    Sammanfattning : The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. LÄS MER
