  1. 1. Wind-wave interaction effects on offshore wind energy

    University dissertation from Department of Energy Sciences, Lund University

    Author : Ali Al Sam; Lunds universitet.; Lund University.; [2016-11]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-wave; swell; atmospheric boundary layer; marine atmospheric boundary layer; atmospheric turbulence; Large-eddy simulation; actuator line; wind sea; offshore technology; wind energy; wind turbine; aerodynamic;

    Abstract : This thesis is devoted to the investigation of the impacts of fast moving ocean surface waves on the aerodynamics of offshore wind turbines. The impacts of non-locally generated waves (swell) on the Marine Atmospheric BoundaryLayer (MABL) and thereby on offshore wind turbine aerodynamics are studied numerically by using Large Eddy Simulations and the Actuator Line Method.

  2. 2. Configuration study of large wind parks

    University dissertation from Chalmers University of Technology

    Author : Stefan Lundberg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; wind parks; configurations; offshore; losses; energy capture; production cost; HVDC; DC DC converters; control; power quality; flicker; PCC;

    Abstract : In this thesis, layouts of various large-scale wind parks, using both AC as well as DC, are investigated. Loss modelling of the wind park components as well as calculations of the energy capture of the turbines using various electrical systems are performed, and the energy production cost of the various park configurations is determined.

  4. 4. Numerical Computations of Wakes Behind Wind Farms

    University dissertation from Uppsala : Institutionen för geovetenskaper

    Author : Ola Eriksson; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wind turbine; Wind power; Wind farm; Wakes; Long distance wakes; Farm-Farm; Farm to farm interaction; Wind farm cluster; Large Eddy simulations; LES; Actuator disc method; ACD; CFD; Ellipsys3D;

    Abstract : More and larger wind farms are planned offshore. As the most suitable build sites are limited wind farms will be constructed near to each other in so called wind farm clusters. Behind the wind turbines in these farms there is a disrupted flow of air called a wake that is characterized by reduced wind speed and increased turbulence. READ MORE

  5. 5. Finding the right place - The story about an offshore wind power project

    University dissertation from Göteborg : Göteborg University
