摘要： The present disclosure relates to controlling an operation of a wind turbine. A first plurality of extreme load measures indicative of extreme loads experienced by at least part of the wind turbine during the first period of time are determined and a load probability characteristic is then determined based on a statistical analysis of the distribution of the first plurality of extreme load measures. A control strategy for controlling the operation of the wind turbine is then modified based at least in part on a comparison of the load probability characteristic and a design load limit and the wind turbine is then subsequently controlled in accordance with the modified control strategy for a second period of time.

摘要： An abnormality determination method for a wind power generation device includes: a measurement step (step S1) of measuring sound emitted by the wind power generation device and recording acoustic data; an analysis step (step S2) of performing a spectrogram analysis on the acoustic data recorded in the measurement step, on a frequency axis and in a temporal axis space as a temporal change in a frequency characteristic by using the short-time Fourier transform or the wavelet transform; a detection step (step S3) of detecting, from the analysis result in the analysis step, a signal component emitted from an abnormal portion of the wind power generation device in a time corresponding to rotation of the wind power generation device; and a determination step (step S5) of determining that the wind power generation device is abnormal when the signal component detected in the detection step is greater than or equal to a certain threshold value.

摘要： A device may receive historical operational data for a mechanical system, such as a rotor blade of a wind turbine. The device may determine one or more quality grades for each of one or more materials of the system, e.g., the rotor blade. The one or more quality grades may be determined by using a data model to process the historical operational data. The data model may be trained using machine learning based on one or both of historical operational data for similar systems, e.g., other rotor blades, and end-of-life (EOL) testing data for the same. The device may determine a recycling recommendation based on the one or more quality grades. The recycling recommendation may include instructions relating to recycling the one or more materials. The device may deliver the recycling recommendation to another device or recipient.

摘要： A method for setting a fully or partially built wind power installation having a rotor having a plurality of rotor blades whose blade angle can be adjusted, wherein the wind power installation can take on variable operating situations, and each operating situation is characterized by a combination of settable installation settings of the wind power installation and environmental conditions that can be captured, with the result that an operating situation can be set for given environmental conditions by setting the installation settings, and operating situations that should be avoided and/or suitable operating situations are stored in a memory by storing a combination of environmental conditions and installation settings as a combination to be avoided for an operating situation that should be avoided in each case, and/or storing a combination of environmental conditions and installation settings as a suitable combination for a suitable operating situation in each case, and, to avoid operating situations that should be avoided, environmental conditions are captured and, depending on the captured environmental conditions and the stored combinations to be avoided and/or suitable combinations, installation settings of the wind power installation are selected and set such that installation settings of stored combinations to be avoided are avoided, and/or installation settings are selected from stored suitable combinations.
