Abstract
A method for ascertaining a wind direction at a wind power installation having a rotor on which at least one rotor blade is arranged. The method includes measuring first wind speeds in a predefined first measuring direction and second wind speeds in a predefined second measuring direction different from the first measuring direction in each case with a measuring frequency at a measuring point for a measuring period, wherein the measuring period is defined by a rotational distance of the rotor or by a prespecified time, wherein the rotor blade or one of the rotor blades passes the measuring point in the measuring period, and determining a wind direction by vectorial evaluation of the first wind speeds and of the second wind speeds.
