  1. 1. The Dissipating Energy Flow method for analysing generator contribution to power system damping -- evaluation and interpretation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Hampus Möller; [2019]
    Nyckelord :Electromechanical oscillations; small-signal stability; energy flow; PMU measurements; forced oscillations; dissipating energy.; Technology and Engineering;

    Sammanfattning : Electromechanical oscillations is a power system phenomenon where generator rotors oscillate, leading to oscillatory power flows. Damping of such oscillations is important for system stability. Forced oscillations is a special case where one faulty component is the source of the oscillation. LÄS MER

  3. 2. MODELLING OF LARGEPOWER SYSTEMS AND TUNING OFREGULATORS’ PARAMETERS

    Master-uppsats, KTH/Elektriska energisystem

    Författare :David Petesch; [2013]
    Nyckelord :;

    Sammanfattning : Interconnection between France and Italy under the Alps could impact the European power system stability. Indeed, the HVDC lines are active elements of electrical grid that influence its dynamic behaviour in case of disturbances. LÄS MER

  4. 3. ESTIMATION OF ELECTROMECHANICAL OSCILLATIONS IN THE NORDIC POWER SYSTEM USING SYNCHROPHASOR MEASUREMENT DATA

    Uppsats för yrkesexamina på avancerad nivå, KTH/Elektriska energisystem

    Författare :Sebastian Bengtsson; [2011]
    Nyckelord :;

    Sammanfattning : Unstable electromechanical dynamics, or electromechanical modes, may cause large amplitude oscillations that may lead to system break-ups or partial blackouts. Thus, the monitoring and study of these modes are of prominent importance and can be of great help for system operators and planning engineers. LÄS MER
