  1. 16. New Topology for STATCOM

    Master-uppsats, KTH/Elkraftteknik

    Författare :Marta Ibáñez Sánchez; [2017]
    Nyckelord :STATCOM; Modular Multilevel Converter; Chain-Link; negative sequence capability; common dc-link; bi-directional switches;

    Sammanfattning : Static compensators (STATCOM) based on high-power converters are widely used for utilitiesand industrial applications in order to enhance the power system reliability. Nowadays,the Chain-Link Modular Multilevel Converter is the best solution for such applications,providing high eciency and reliability, and good harmonic performance. LÄS MER

  3. 17. An MMC-based topology with Dual-Active-Bridge power channels for load balancing in 50 Hz-railway applications

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

    Författare :Andreas Zafeiropoluos; [2017]
    Nyckelord :Power electronics; STATCOM; MMC; power channel; power quality; negativesequence compensation; high-speed trains;

    Sammanfattning : The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. LÄS MER

  4. 18. Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

    Master-uppsats, KTH/Elkraftteknik

    Författare :Luai Malki; [2017]
    Nyckelord :FACTS; Hybrid-STATCOM; TSC; TSR; VSC; passive filter; active filter; PWM; MMC; passivity; input admittance; resonance; harmonics; ABB;

    Sammanfattning : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.

  5. 19. Application for Wind Farm Integration Complying with the Grid Code by Designing an Outer Control Strategy for the Converter.

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

    Författare :Alexandra Kapidou; [2016]
    Nyckelord :Wind Farm; STATCOM; Grid Code; Positive and Negative Sequence Current Controller; Reactive Power Compensation;

    Sammanfattning : The continuously increasing energy penetration from wind farms into the grid raises concerns regarding power quality and the stable operation of the power system. The Grid Code´s requirements give strict guidelines for a wind farm´s behaviour under faulty or abnormal operating conditions. LÄS MER

  7. 20. Development of EMT Simulation Model to Use RMS Control Model

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

    Författare :Priya Kalikavunkal; [2016]
    Nyckelord :;

    Sammanfattning : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. LÄS MER
