1 SHADOW - Main Result Assumptions for shadow calculations Maximum distance for influence Calculate only when more than 20 % of sun is covered by the blade Please look in WTG table WindPRO version :28 / 1 Minimum sun height over horizon for influence 3 Day step for calculation 1 days step for calculation 1 minutes Sunshine probability S (Average daily sunshine hours) [LULEA] 0,60 2,61 4,18 6,47 8,80 10,60 9,50 6,88 4,22 2,77 1,22 0,17 Operational hours are calculated from in calculation and wind distribution: MERRA_basic_E25.335_N Operational time N NNE ENE E ESE SSE S SSW WSW W WNW NNW Sum Idle start wind speed: Cut in wind speed from power curve A ZVI (Zones of Visual Influence) calculation is performed before flicker calculation so non visible WTG do not contribute to calculated flicker values. A WTG will be visible if it is visible from any part of the receiver window. The ZVI calculation is based on the following assumptions: Height contours used: Height Contours: Kukonaho height contour lines.wpo (1) Obstacles used in calculation Eye height: 1,5 m Scale 1: Grid resolution: 10,0 m New WTG Finish TM ETRS-TM35FIN-ETRS89 WTG type Shadow data East North Z Row Valid Manufact.
