1 SHADOW - Main Result Assumptions for shadow calculations Maximum distance for influence m Minimum sun height over horizon for influence 3 Day step for calculation 1 days step for calculation 1 minutes The calculated times are "worst case" given by the following assumptions: The sun is shining all the day, from sunrise to sunset The rotor plane is always perpendicular to the line from the WTG to the sun The WTG is always operating WindPRO version :31 / 1 To avoid flicker from not visible a ZVI calculation is performed before the flicker calculation. The ZVI calculation is based on the following assumptions Height contours used: Height Contours: CONTOURLINE_Ryfors_0.wpo (1) Obstacles not used in calculation Eye height: 1,5 m Grid resolution: 10 m Scale 1: New WTG Shadow receptor RN WTG type East North Z Row data/description Valid Manufact.
