Abstract
Vindenergi er blevet hovedkilden indenfor strømforsyningssektoren. Oprettelse af grid-forbundne vindparker er stadig stigende på grund af deres bidrag til grøn energi. Kvaliteten på strømmen er en udfording for vindenergisektoren, Endvidere, er det kritiske punkt måling af strømkvaliteten, såsom omfanget af flicker og harmonisk forvrængning. Derfor, fastsætter IEC standarden måleprocedurerne for flicker og harmonisk forvrængning. Effekterne på spændingsvariationer associeret med flicker og signal forvrængning er kendt som harmonisk forvrængning. Målingen af flicker og harmoinisk forvrængning i vindturbiner er emnet for denne afhandling. Afhandlingen falder i to dele. Den første del beskriver flicker målemetoden og den anden del definerer målemetoden for harmonisk forvrængning. Resultaterne demonstreres ved hjælp af simulering gennem den opgraderede IEC måle- og vurderingsstandard.
The wind energy is becoming the mainstream source of the power sector. The installation of the grid-connected wind farm is increasing because of their contribution to the green energy. The power quality is the challenge of the wind energy. Moreover, the critical issue in the measurement of power quality effects such as severity of flicker and harmonic. Therefore, the IEC standards define the measurement procedure for flicker and harmonic. The effects of voltage fluctuations associated with the flicker and the signal distortions are known as harmonics. The measurement of flicker and harmonic to the wind turbine is dealt with in this dissertation. The thesis consists of two parts. The first part described the flicker measurement model and the second part define the harmonics measurement model. The results demonstrated through simulation according to the upgraded version of IEC measurement and assessment standard.
