    摘要: A control arrangement of a wind turbine includes a watchdog including a reset module and a trigger module, wherein the watchdog reset module is configured to perform an internal reset when a sign-of-life signal is received from a remote communication system within a predetermined time limit, and wherein the watchdog trigger module is configured to issue a watchdog trigger when the predetermined time limit is exceeded; a sensor arrangement including a number of sensors configured to observe local parameters and to report local sensor data; and a wind turbine controller that initiates a local control sequence in response to the watchdog trigger, which local control sequence is configured to switch between a first mode of operation and a second mode of operation on the basis of the local sensor data. A method of operating a wind turbine is further provided.

    摘要: A method for manufacturing a wind turbine blade, the method including the steps: a) positioning an outboard blade section at a predefined end position, the outboard blade section including an outboard end portion, b) positioning an inboard blade section adjacent to the outboard blade section, the inboard blade section including an inboard end portion, c) determining a deviation of a current position of the inboard end portion of the inboard blade section with respect to the outboard end portion the outboard blade section from a nominal position of the inboard end portion with respect to the outboard end portion, and d) moving the inboard blade section to the outboard blade section to compensate for the determined deviation. The complexity of the alignment procedure when aligning lengthwise blade sections are reduced and the accuracy of the alignment increased.

    摘要: A method of controlling plural wind turbines is provided, wherein each wind turbine is operable in different operating modes, wherein operating parameters and/or operating features are set differently in the different operating modes. For at least a first of the plural wind turbines, at least some of the different operating modes have a different impact on a residual lifetime of at least a second of the plural wind turbines. In embodiments, the method includes providing at least one candidate operating scheme and estimating a residual lifetime and/or at least one optimization parameter. Estimating of the residual lifetime and/or the optimization parameter considers the impact of the operating mode of the first wind turbine specified in the candidate operating scheme on the residual lifetime of the second wind turbine. The plural wind turbines are then operated in accordance with an operating scheme selected from the candidate operating schemes.

    摘要: A rotor blade with a leading edge and a trailing edge is provided, wherein the rotor blade is designed and configured for being exposed to a fluid flowing substantially from the leading edge to the trailing edge, the rotor blade includes at least two sensors designed for detecting flow characteristics of the fluid and providing respective sensor signals, and the rotor blade further includes at least two actuators for producing an anti-noise signal based on a sensor signal, the sensors are arranged spanwise and the actuators are arranged chordwise at the surface of the rotor blade, and the actuators are arranged and prepared such that flow-induced edge noise of the rotor blade, which is generated by the fluid, is at least partly cancelled out by the anti-noise signal. Also provided is a method for creating such rotor blade and a related wind turbine.

    摘要: A wind turbine rotor blade load emulator arrangement includes a support unit constructed to support a rotor blade during a fatigue test procedure; an exciter configured to deflect the rotor blade during a fatigue test procedure; and a stiffness augmentation assembly for mounting to the rotor blade over a mounting length, which stiffness augmentation assembly is realized to increase the stiffness of the rotor blade in the mounting length. A method of carrying out a fatigue test procedure on a wind turbine rotor blade uses such a load emulator arrangement.
