2. 1. Energy from Ocean Waves : Full Scale Experimental Verification of a Wave Energy Converter

   Author : Rafael Waters; Mats Leijon; Jan Sundberg; Jonny Hylander; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; wave energy converter; sea trials; ocean energy; linear generator; point absorber; search coil; wave climate; utilization; Engineering physics; Teknisk fysik;

   Abstract : A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. READ MORE

4. 2. 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

5. 3. 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

6. 4. Sea Level Compensation System for Wave Energy Converters

   Author : Valeria Castellucci; Rafael Waters; Ronan Costello; Uppsala universitet; []
   Keywords : Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

   Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

7. 5. Adaptation of wave power plants to regions with high tides

   Author : Mohd Nasir Ayob; Rafael Waters; Johan Abrahamsson; Ian Masters; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy; Tides; Wave Hub; Lysekil research site; Control system; Tidal compensator; Wave energy converter.; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Abstract : The wave energy converter (WEC) developed at Uppsala University is based on the concept of a heaving point absorber with a linear generator placed on the seafloor. The translator inside the generator oscillates in a linear fashion and is connected via a steel wire to a point absorbing buoy. READ MORE
