Extreme value estimation

For your wind farm, we calculate the 50-years extreme wind speed based on site-specific time series from our Germany 3km wind atlas. The calculation procedure for the extreme wind speeds is based on the method of the program WindPRO. The applied gumbel adaption is based on the least squares method.

Extreme value picture

The calculation procedure includes the following steps:

  • Calculation of site-specific wind speed time series (min. 20 years) at the desired hub height for the most conservative (highest wind speed) WTG.
  • With 40 onshore measurements, a scale factor for extreme wind speeds will be calculated and applied to the time series.
  • With a gumbel distribution the extreme value and standard deviation for 50 years will be calculated.

Initial estimation

A site-specific* initial estimation based on our anemos Wind atlases assists you with the decision for the correct measurement location. Furthermore, a preliminary estimation can form the basis for turbulence calculations and it allows you to compare different WTG types.

Our initial estimation for your site contains:

  • mean wind speed and optionally mean energy yield (20 years)
  • frequency distribution of wind speed and wind direction
  • directional Weibull distribution (12 sectors)
  • annual cycle of wind speed and optionally energy yield
  • optional consideration of wake effects plus further losses
  • .tab file for application in WAsP, WindPRO, Meteodyn, etc.

* site-specific estimation for Germany and France available; for other regions, the spatial resolution of the corresponding wind atlases applies

Production atlas

energy yield Germany 3km.M2

Do you need a quick estimate of energy yield for diverse specific wind turbine generators? Our anemos production atlas calculates the energy yields with your given power curves and hub heights.

Therefore, the production atlas allows a comparison between different WTG technologies. Plus, it is a tool for selecting a suitable wind farm site or for expanding your portfolio.

Gladly, we generate wind farm specific production time series for you which consider your given wind farm configuration and losses.

You receive the production data either as site-specific* time series or as map(s) of the mean energy yield of the last 20 years; available with 90 m x 90 m resolution (for Germany and France)
