  • Patent number: 7870783
    Abstract: The present invention provides a method for measuring the turbulence intensity of a horizontal axis wind turbine that is capable of accurately obtaining the value of the turbulence intensity without the effect of the rotor and by taking into consideration the motion of the nacelle. In the method for measuring the turbulence intensity of a horizontal axis wind turbine, with the nacelle located on the upwind side of the rotor of the horizontal axis wind turbine, measurement values are obtained from an anemometer that is located on the nacelle and an acceleration sensor that is fastened to the nacelle, and the absolute value of the turbulence intensity is calculated based on the measurement values from the anemometer and the measurement values from the acceleration sensor. As a result, it is possible to accurately calculate the absolute value of the turbulence intensity that includes the effect of the movement of the nacelle.
