WAsP interface - Main ResultCalculation: WAsP Interface example

Name for WAsPSite coordinatesUTM NAD27 Zone: 14 East: 451,101 North: 5,110,347

Air density calculation mode Individual per WTGResult for WTG at hub altitude 1.165 kg/m³Air density relative to standard 95.1 % Hub altitude above sea level (asl) 744.6 m Annual mean temperature at hub alt. 3.5 °C Pressure at WTGs 924.9 hPa

The calculation is based on conversion of a wind statistic (wind climate forthe region) through a terrain modeling (roughness, elevation and localobstacles) to wind distribution on the turbine position based on theWINDATLAS method (Risø/DTU), where the software package WAsP(Risø/DTU) is used for performing the calculations. The calculated winddistribution is converted to expected annual energy production (AEP)through the power curve and air density correction.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see WindPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.
