摘要： A method and device for controlling a wind turbine and a storage medium are provided. The method includes obtaining a mapping of the wind turbine; determining a starting power for starting an advance pitch control based on the mapping of the wind turbine; in response to a rotation speed of the wind turbine reaching a first rated rotation speed and a power of the wind turbine reaching the starting power, increasing a motor torque and increasing a pitch angle to make the hub thrust of the turbine change by following the limit boundary of hub thrust; and increasing the pitch angle to maintain the rotation speed of the wind turbine at the first rated rotation speed until a target wind speed is reached, in response to the power of the wind turbine being increased to the exceeded power.

摘要： A method for monitoring a machine state of a machine system, in particular a wind power plant, may include the steps of providing a time series of measured natural vibration spectra of the machine system, detecting a deformation parameter in at least one monitoring time interval, wherein the deformation parameter is characteristic of a deviation of the measured natural vibration spectra from a reference natural vibration spectrum of at least one reference machine system, detecting a noise parameter at the at least one monitoring time interval, wherein the noise parameter is characteristic of a noise of the measured natural vibration spectra, and determining the machine state from the deformation parameter and the noise parameter. A monitoring apparatus for monitoring a machine state of a machine system, in particular a wind power plant, is also described.

摘要： Systems and methods of predicting performance of one or more wind turbines are provided. Exemplary methods include entering data inputs and analyzing and estimating the data inputs. The data inputs include nacelle position information and/or wind condition information. A wake model is determined based on the analysis and estimating of the data inputs. Wind turbine behavior predictions are generated including predicted power outputs of the wind turbines and predicted effects of waking on the predicted power outputs. The data inputs can be adjusted to improve the wind turbine behavior predictions, and the wake model can be corrected by machine learning. By focusing on an observable quantity—power—based on other observable quantities like wind speed, yaw error, nacelle position, disclosed embodiments enable optimization to start immediately after the hardware and software are installed, and as the controller operates more in the field, additional training and validation data are collected.
