  5. 4. Control Strategies for VSC-HVDC links in Weak AC Systems

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Erik Björklund; [2019]
    Keywords : HVDC; VSC; voltage source converter; control theory; weak ac systems;

    Abstract : In this master thesis control systems for a voltage-source converter HVDC connected to weak ac networks are investigated. HVDC stands for high voltage direct current and is a way to transfer power in the electrical power system. READ MORE

  6. 5. Analysis of harmonic cross-modulation in HVDC line-commutated converters for practical design purposes

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Casper Karlsson; [2018]
    Keywords : Power transmission; design; filters;

    Abstract : The use of HVDC has many benefits over HVAC for some specific power transmission purposes. However, two major problems with HVDC links are that the converters produce harmonics and consume reactive power. Electrical filters are used to compensate for this and are a major cost driver of HVDC links. READ MORE
