摘要： A method for operating an electric machine (in particular a wind turbine) having a generator with a rotor and a stator is provided. The method includes: i) evaluating an active damping applied to the electric machine, ii) estimating a damping criterion from the evaluated applied active damping, and iii) shifting a dynamic capacity curve towards a maximum allowed level. The maximum allowed level is based on the damping criterion and a first operation criterion and/or a second operation criterion. Furthermore, the dynamic capacity curve is a dynamic power capacity curve or a dynamic torque capacity curve.

摘要： Provided is a method for detecting a wind gust that affects a wind turbine, wherein the wind turbine includes two or more blades which are coupled to a connection means so that the blades are essentially arranged in a common plane. The method including: i) measuring an event that at least one blade is at least partially out of the plane to obtain a measurement signal, ii) providing the measurement signal as a measurement input signal to an evaluation algorithm, iii) elaborating a detection result from the measurement input signal using the evaluation algorithm, and iv) comparing the detection result with a predefined wind gust threshold value (h) to determine, if a wind gust is detected. Furthermore, a wind gust detection system, a wind turbine that includes the system, and a wind turbine operating method are provided.

摘要： A method of handling a wind turbine is provided including a nacelle coupled via a yawing system to a tower for protection against high wind load, the method including: supplying a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation; exerting, by the yawing actuator, a torque to the nacelle relative to the tower, thereby turning the nacelle to a second orientation being a downwind orientation.

摘要： A method of operating a wind turbine, in particular plural wind turbines of a wind park, includes: receiving, by the wind turbine or a wind park controller, safety relevant information from an external source external to the wind turbine; activating, by the wind turbine or the wind park controller, a safe operation mode depending on the received information, wherein the external source is different from a wind park controller.
