Here you will find usefull tools for calculations related to wind power.

Wind Profile

The wind profile calculator enables an estimate for the vertical wind speed profile, i.e. the increase of wind speed with height above ground.

Weibull Distribution

This tool can be used to approximate a wind speed distribution with a Wiebull function. The obtained Weibull parameters may subsequently be used in the power calculator to estimate the production of a wind turbine.

Air Density

Air density decreases with altitude and thus a wind turbine's production decreases. Air density can be calculated either from the altitude or from measurements of temperature and air pressure.

Power Production

The power production calculator estimates power production for a number of turbine types or for any power curve specified.
