  • Wind turbine measurement system
    Patent number: 11280315
    Abstract: A measurement system is provided for a wind turbine having a plurality of rotor blades mounted to a spinner at the front of a nacelle and arranged to rotate in a rotor plane. The measurement system includes a measuring device for determining a pressure at a number of pressure measurement points. The pressure measurement points are arranged in front of the rotor plane, an analysis module for generating a control signal on the basis of the pressure measurements, and output means for issuing the control signal to a controller of the wind turbine.

  • Method of detecting a degree of yaw error of a wind turbine
    Patent number: 10012209
    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.
