Abstract: A method for determining a correction function for a wind turbine, a method and system for determining an alignment correction function for a nacelle of a wind turbine, and a method for operating a wind turbine are provided. Measurement values of the power measure of the wind turbine and of the leeward wind direction are assigned to measurement values of the leeward wind speed, corrected by a correction function, and are grouped into at least one wind-speed bin on the basis of instants at which the measurement values were recorded. A model function is determined and outputted for a relationship between the power measure and the leeward wind direction for the wind-speed bin, and an alignment correction function is determined for a target alignment of the nacelle relative to the measured leeward wind direction on the basis of the model function.

Abstract: The present invention relates to a method for determining a correction function for a wind turbine, to a method and a system for determining an alignment correction function for a nacelle of a wind turbine, and to a method for operating a wind turbine. A power measure of the wind turbine, a leeward wind direction, and a leeward wind speed are measured, a multiplicity of measurement values being recorded over a defined time period in each case. The measurement values of the power measure and of the leeward wind direction are assigned to measurement values of the leeward wind speed, corrected by means of a correction function, that are grouped into at least one wind-speed bin, on the basis of instants at which the measurement values were recorded.

Abstract: A method for determining an energy yield loss of a first wind turbine of a wind farm that includes a plurality of wind turbines. The first wind turbine is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine is determined. At least one second wind turbine is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine is determined and depending upon the energy yield of the at least one second wind turbine, an energy yield potential of the first wind turbine is determined. The difference between the energy yield potential of the first wind turbine and the determined reduced energy yield is formed.

The first wind turbine (1-49) is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine (1-49) is determined. At least one second wind turbine (1-49) is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine (1-49) is determined and depending upon the energy yield of the at least one second wind turbine (1-49), an energy yield potential of the first wind turbine (1-49) is determined. The difference between the energy yield potential of the first wind turbine (1-49) and the determined reduced energy yield is formed.
