Abstract
A method of determining a degree of yaw error of a wind turbine is provided. The method includes obtaining wind pressure measurement values from in front of the rotor plane, which wind pressure measurement values exhibit a periodic nature related to a rotation of a spinner of the wind turbine, performing a signal processing step to process the wind pressure measurement values to determine a phase offset of the wind pressure measurement values relative to an angular reference, and deriving a yaw error angle from the phase offset. A method of establishing a relationship between a phase offset of wind pressure measurement values and a degree of yaw error of a wind turbine, a yaw error determination unit, and a wind turbine are also provided.
