  2. 1. Electrical Systems for Wave Energy Conversion

    Author : Cecilia Boström; Mats Leijon; Daniel Karlsson; Uppsala universitet; []
    Keywords : Wave power; direct driven linear generators; electrical systems; non-linear loads; TECHNOLOGY; TEKNIKVETENSKAP; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Wave energy is a renewable energy source with a large potential to contribute to the world's electricity production. There exist several technologies on how to convert the energy in the ocean waves into electric energy. The wave energy converter (WEC) presented in this thesis is based on a linear synchronous generator. READ MORE

  4. 2. Ocean Wave Energy : Underwater Substation System for Wave Energy Converters

    Author : Magnus Rahm; Mats Leijon; Ted Brekken; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave energy; wave power; wave energy converter; direct-drive; permanent magnet linear generator; point absorber; array; farm; park; offshore; marine; substation; electrical transmission system; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : This thesis deals with a system for operation of directly driven offshore wave energy converters. The work that has been carried out includes laboratory testing of a permanent magnet linear generator, wave energy converter mechanical design and offshore testing, and finally design, implementation, and offshore testing of an underwater collector substation.

  5. 3. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter

    Author : Yue Hong; Rafael Waters; Mikael Eriksson; Cecilia Boström; Jørgen Hals Todalshaug; Uppsala universitet; []
    Keywords : linear generator; point absorber; numerical modelling; power production; optimal damping; Teknisk fysik; Engineering Science;

    Abstract : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. READ MORE

  6. 4. Theoretical and Experimental Analysis of Operational Wave Energy Converters

    Author : Erik Lejerskog; Mats Leijon; Rafael Waters; John Ringwood; Uppsala universitet; []
    Keywords : ocean wave energy; WEC; permanent magnet; linear generator; closed stator slots; offshore experiments;

    Abstract : This thesis studies wave energy converters developed at Uppsala University. The wave energy converters are of point absorbing type with direct driven linear generators. The aim has been to study generator design with closed stator slots as well as offshore experimental studies. READ MORE
