  1. 1. On control of cascaded H-bridge converters for STATCOM applications

    Författare :Ehsan Behrouzian; Chalmers University of Technology; []
    Nyckelord :cascaded H-bridge converters; FACTS.; Modular Multilevel Converters MMC ; STATCOM;

    Sammanfattning : Cascaded H-bridge (CHB) converters are today considered the industrial standard for STATCOM applications, mainly due to their small footprint, high achievable voltage levels, modularity and reduced losses. However, there are still areas of research that need to be investigated in order to improve the performance and the operational range of this converter topology for grid-applications. LÄS MER

  2. 2. Operation and control of cascaded H-bridge converter for STATCOM application

    Författare :Ehsan Behrouzian; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular Multilevel Converters MMC ; STATCOM; FACTS.; cascaded H-bridge converters;

    Sammanfattning : In the last decade, particular attention has been paid to the use of Modular Multilevel Converters(MMC) for grid applications. In particular, for STATCOM applications the phase leg ofthe converter is constituted by a number of single-phase full-bridge converters connected incascade (here named Cascaded H-Bridge, CHB, converter).

  3. 3. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM

    Författare :Paulo Fischer de Toledo; Hans-Peter Nee; Gustaf Ohlsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Keywords : HVDC transmission; LCC – Line-commutated Current-source Converter; STATCOM; VSC – Voltage Source Converter; Space-Vector complex vector ; transfer-function; frequency-domain analysis; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. LÄS MER
