  3. 3. Power Quality Analysis of a 110 MW Wind Farm in a 130 kV Switchyard

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : My Näslund; [2012]
    Keywords : Power Quality; Flicker; Interharmonics; Harmonics; Unbalance; Wind Power; Elkvalitet; Flimmer; Obalans; Mellantoner; Övertoner; Vindkraft;

    Abstract : Good power quality is not only determined by uninterruptable power supply, voltage deviations also affect the function of the network and the equipment connected. Electromagnetic disturbances as flicker, harmonics, interharmonics and unbalance are decreasing the power quality. READ MORE
