  1. 1. Marine Current Resource Assessment : Measurements and Characterization

    Författare :Nicole Carpman; Karin Thomas; Mats Leijon; Sandra Eriksson; Mairead Atcheson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADCP; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. LÄS MER

    Sammanfattning : Marine currents, i.e. water currents in oceans and rivers, constitute a large renewable energy resource. This thesis presents research done on the subject of marine current energy conversion in a broad sense. LÄS MER

  4. 3. Medium Voltage Generation System with Five-level NPC Converters for Kite Tidal Power

    Författare :Georgios Mademlis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage balancing; Maximum Power Point Tracking MPPT ; Medium Voltage Converters; Multilevel Space-Vector-Modulation; Neutral point clamped converter NPC ; Subsea kite; Tidal power;

    Sammanfattning : Offshore power generation has emerged as a prominent source of energy and the installed capacity of new plants has been steadily increasing in recent years. Tidal power specifically is a promising renewable energy source which has not been highly exploited yet, despite its distinctive advantages of being predictable and independent of weather conditions.
