Abstract
Vindenergi er ved at blive en hovedkilde i elsektoren. Antallet af nettilsluttede vindparker stiger, fordi de bidrager til grøn energi. Samtidig bliver elkvalitet en central udfordring. To vigtige forhold er flimmer, som skyldes spændingsudsving og kan få lys til at flimre, og harmoniske, som er uønskede frekvenskomponenter, der forvrænger det elektriske signal. IEC-standarder angiver, hvordan flimmer og harmoniske skal måles. Denne afhandling præsenterer to målemodeller for vindmøller: én til flimmer og én til harmoniske. Resultaterne vises gennem simuleringer i overensstemmelse med den opdaterede IEC-standard for måling og vurdering.
Wind energy is becoming a mainstream source of electricity. The number of grid-connected wind farms is growing because they contribute to green energy. At the same time, power quality is a key challenge. Two important aspects are flicker, caused by voltage fluctuations that can make lights flicker, and harmonics, unwanted frequency components that distort the electrical signal. IEC standards specify how flicker and harmonics must be measured. This thesis presents two measurement models for wind turbines: one for flicker and one for harmonics. The results are demonstrated through simulations in line with the updated IEC measurement and assessment standard.
