WindDataSuite imports power curve data in the formats WAsP-WTG, WAsP-POW, and WDS-CSV, and exports power curve data in the formats WAsP-WTG and WDS-CSV.

With WindDataSuite, you can edit power curve data and adjust them to other air densities, and you can calculate the reference yields for the power curves in accordance with EEG 2014 and EEG 2017.

In calculations with power curve data (as e.g. for the calculation of energy yields), WindDataSuite follows the hysteresis loop for the power generation as it is defined by the special cut-in/cut-out values of the power curve. This also applies for the new generation of wind turbines with "storm control", which allows a slow shutdown at high wind speeds.

Fig.1 shows a fictitious power curve with such a storm control: low cut-in wind speed value of 3.0 m/s, high cut-out wind speed value of 25 m/s, high cut-in wind speed value of 21.0 m/s, and low cut-out wind speed value of 1 m/s. Please note that this is just an example.

Fig.2 shows a parameter-diagram of the fictitious power curve for diverse air densities and noise levels.
