    摘要: The invention comprises a turbulence sensor and sensor system for determining the condition of a wind turbine blade. A turbulence sensor comprises a sensor membrane provided in the surface of a wind turbine blade. A light source and light detector provided in a sensor cavity in the blade illuminate the sensor membrane and detect the light reflected back. The reflected light is mixed with non-reflected light to give an interference pattern indicative of the quality of the airflow, whether it is laminar or turbulent. The turbulence sensor can be used in a sensor system for detecting the accumulation of unwanted matter, such as dirt or ice, on the blade.

    摘要: A rotor of a wind turbine may cast an intermittent shadow onto an object in the vicinity of the turbine. A shadow-control system stops the wind turbine, based on a shadow-related shut-down condition. The condition is based on a result of a comparison between a direct-light intensity and an indirect-light intensity being beyond a direct-to-indirect light threshold. A set of light sensors measures the direct- and indirect-light intensities. A sensor measures the direct light intensity when irradiated by the sun, and the indirect-light intensity when not irradiated by the sun. The set of light sensors to provide the measured direct- and indirect-light intensities for the comparison consists of two sensors, an eastward-oriented sensor and a westward-oriented sensor.

    摘要: A wind turbine includes a number of blades and an optical measurement system comprising a light source, such as a laser, an optical transmitter part, an optical receiver part, and a signal processor. The light source is optically coupled to the optical transmitter part, which includes an emission point for emitting light in a probing direction. The optical receiver part comprises a receiving point and a detector. The optical receiver part is adapted for receiving a reflected part of light from a probing region along the probing direction and directing the reflected part of light to the detector to generate a signal used to determine a first velocity component of the inflow. The emission point is located in a first blade at a first radial distance from a center axis, and the receiving point is located in the first blade at a second radial distance from the center axis.

    摘要: It is an object to make it possible to completely or partially eliminate a yaw driving device and to reduce power consumption in a nacelle. A moment around a wind-turbine tower axis is calculated; an angle command value around the wind-turbine tower axis is calculated by adding a yaw-control command value to a reference command value for canceling out the moment; and a pitch angle command value of each wind turbine blade is set on the basis of the angle command value around the wind-turbine tower axis.
