  1. 6. Offshore deployments of marine energy converters

    Författare :Maria Angeliki Chatzigiannakou; Irina Temiz; Mats Leijon; Tony Lewis; Uppsala universitet; []
    Nyckelord :offshore deployments; risk assessment; wave energy converter installation; marine current energy converter installation; economic efficiency; time efficiency; offshore operations; point absorber; hydrodynamic analysis; slack sling criterion; hoisting system failure.;

    Sammanfattning : The depletion warning of non-renewable resources, such as gas, coal and oil, and the imminent effects of climate change turned the attention to clean and fossil fuel-free generated electricity. University research groups worldwide are studying solar, wind, geothermal, biomass and ocean energy harvesting. LÄS MER

  3. 7. Grid Connection of Permanent Magnet Generator Based Renewable Energy Systems

    Författare :Senad Apelfröjd; Sandra Eriksson; Frans Dijkhuizen; Uppsala universitet; []
    Nyckelord :VAWT; H-rotor; Tap Transformer; Cascaded H-bridge Multi-Level; Renewable Energy; Wind power; Wave power; Marine Current Power; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Renewable energy is harnessed from continuously replenishing natural processes. Some commonly known are sunlight, water, wind, tides, geothermal heat and various forms of biomass. The focus on renewable energy has over the past few decades intensified greatly. LÄS MER

  4. 8. Electrical System of a Wave Power Plant

    Författare :Cecilia Boström; Uppsala universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Wave energy is a renewable energy source with a large potential to contribute to the world's electricity production. There exist several techniques to convert the energy in the ocean waves into electric energy. The wave energy converter presented in this thesis is based on a linear synchronous generator. LÄS MER

  5. 9. Studying Buoy Motion for Wave Power : Experiments at the Lysekil Research Site

    Författare :Simon Tyrberg; Uppsala universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Since 2002, the Division for Electricity at Uppsala University has been running the Lysekil project. The project is an attempt to construct and evaluate a technology for extracting electrical energy from the motion of ocean waves. The idea is to let this up-and-down motion drive a linear generator.

  7. 10. Underwater Electrical Connections and Remotely Operated Vehicles

    Författare :Flore Remouit; Jens Engström; Jens Abrahamsson; Simon Lindroth; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Remotely Operated Vehicles (ROVs) are underwater robots that perform different kind of operations, from observation to heavier tasks like drilling, carrying and pulling cables, etc. Those ROVs are costly and require skilled personal to operate it as well as equipment for transportation and deployment (boats, cranes, etc.).
