  1. 1. Detektion av fasta ekon vid vindmätning med SODAR

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Datateknik och informatik

    Författare :Viktor Holmgren; Karl-Johan Vikmyr; [2017]
    Nyckelord :SODAR; vindmätning; fasta ekon; mätinstrument;

    Sammanfattning : Purpose – The purpose of this thesis was to facilitate the search for echoes caused by fixed objects, so called fixed echoes, when using SODAR-technique for wind measurements. Furthermore, it was investigated how fixed echoes in measurements can change based on different conditions such as: the angle of the sound beam towards the object causing the echo, the output frequency of the instrument, the air temperature and relative humidity.

  3. 2. Investigation of wind potential variation at three measurement sites based on atmospheric stability and power production

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Lavan Kumar Eppanapelli; [2013]
    Nyckelord :AQ500; SoDAR; Met mast; statistical analysis; atmospheric stability; wind shear;

    Sammanfattning : As tapping energy from wind expands rapidly worldwide, it is a common procedure to locate a practicable site to extract energy from abundant wind flow by building wind farms. Comprehensive understanding of wind resource at a site   is important to perform the main activities say, wind flow modeling, wind   turbines micro siting, annual energy yield calculation and cost of energy   estimation.

  4. 3. Making remote sensing bankable - cold climate SODAR and meteorological mast intercomparison

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Ian Engblom Wallberg; [2010]
    Nyckelord :SODAR; remote sensing; wind power; wind energy; SODAR; fjärranalys; vindkraft; vindenergi;

    Sammanfattning : The value of an easy to install, accurate, far-reaching measurement instrument is easily understood when dealing with setting up and monitoring wind power parks. However the use of remote sensing equipment when doing this is a subject of much discussion amongst professional experts and scholars. LÄS MER
