  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. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

    Master-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Isabelle Löfgren; [2022]
    Nyckelord :impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

    Sammanfattning : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. LÄS MER

  4. 3. The Impact of Voltage Dip Characteristics on Low Voltage Ride Through of DFIG-based Wind Turbines

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

    Författare :Cheng Chen; [2019]
