摘要： Systems and methods for maximizing efficiency and output performance for one or more wind turbines (10) similarly situated and positioned in a geographical site (1). The system includes at least a controller (200) operably connected to the wind turbines and sensors (300) positioned in or proximate to the site for monitoring environmental conditions. The controller receives operation and performance information for each wind turbine and based on the received information establishes an operational parameter that is set as a baseline parameter for adjusting any underperforming wind turbines operational parameters.

摘要： A method for monitoring and assessing power performance changes of one or more wind turbines (2, 3, 4, 5, 6, 7, 8) of a wind farm (1) is disclosed. For each wind turbine (2, 5) to be monitored, a group of reference wind turbines (2, 3, 4, 6) is defined. During a training period a transfer function is generated for each monitored wind turbine (2, 5). The transfer function establishes a relationship between locally measured wind speeds at each of the reference wind turbines (2, 3, 4, 6) and the power performance data for the monitored wind turbine (2, 5), obtained during the training period. During one or more subsequent test periods, measured power performance data for the monitored wind turbines (2, 5) is compared to predicted power performance data. The predicted power performance data is obtained by means of the locally measured wind speeds at the corresponding reference wind turbines (2, 3, 4, 6) during the test period(s) and the previously generated transfer function for the monitored wind turbine (2, 5). This allows even small and/or gradual power performance degradation to be detected.

摘要： Embodiments herein describe using a tower damping system to reduce oscillations in a wind turbine. To do so, the dampening system may use a metric that is decoupled from the activation strategy in order to control the blade pitch and avoid or mitigate feedback loops. In one embodiment, the dampening system measures a force on the turbine that is correlated to a fatigue loading on the tower. Furthermore, the turbine may perform a calculation to decouple the force from the activation strategy. That is, the turbine determines the value of the force as if the damping system was not activated or present. In addition, the dampening system uses the current wind speed and a wind distribution to generate a pitch reference value. The dampening system may use both the pitch reference value and the fatigue loading on the tower to reduce the tower oscillations.

摘要： A method for iteratively estimating a wind speed at a wind turbine is disclosed, said wind turbine comprising a rotor carrying a set of wind turbine blades, each wind turbine blade having a variable pitch angle. A minimum tip speed ratio, λ min , is derived, based on an obtained pitch angle, θ. The minimum tip speed ratio, λ min , defines a limit between a stable and an unstable control region. An initial tip speed ratio, λ init > λ min , is selected, and an initial estimated wind speed, v init , is derived based on the initial tip speed ratio, λ int , and an obtained rotational speed, ω, of the rotor. An estimated wind speed, v est , is iteratively derived, based on the obtained rotational speed, ω, and the obtained pitch angle,ω, and using the derived initial estimated wind speed, v init , as a starting point. The iterative process converges fast and reliably.

摘要： The present subject matter is directed to a system and method for optimizing wind turbine operation. For example, the present disclosure is configured to generate operating data for at least one operational parameter of the wind turbine for a predetermined time period. The system can then determine a robustness measurement of at least a portion of the operating data. In general, the robustness measurement indicates the tendency of the operating data to be affected by outliers present in the operating data. In addition, the robustness measurement is typically a function of a distribution of the operating data. The present disclosure is then configured to determine at least one optimal set point for the operational parameter as a function of the robustness measurement and a power production of the wind turbine. The wind turbine can then be operated based on the optimal set point.

摘要： The invention relates to a method for the computer-supported generation of a data-driven model (NM) of a technical system, in particular of a gas turbine or wind turbine, based on training data. The method according to the invention is characterized in that the data-driven model is preferably learned in regions of training data having a low data density. According to the invention, it is thus ensured that the data-driven model is generated for information-relevant regions of the training data. The data-driven model generated by the method according to the invention is used in a particularly preferred embodiment for calculating a suitable control and/or regulation model or monitoring model for the technical system. By determining optimization criteria, such as low pollutant emissions or low combustion dynamics of a gas turbine, the service life of the technical system in operation can be extended. The data model generated by the method according to the invention can furthermore be determined quickly and using low computing resources, since not all training data is used for learning the data-driven model.

摘要： A method for thermal conditioning of a wind turbine nacelle is disclosed. The method comprises the steps of: Obtaining historical, statistical and/or forecast data relating to ambient conditions of the wind turbine, e.g. in the form of wind data, weather forecasts and/or thermal data of the wind turbine. Calculating a setting for at least one conditioning unit, e.g. a cooling unit or a heating unit, arranged in an interior part of the nacelle, based on the obtained historical, statistical and/or forecast data, and operating the conditioning unit(s) in accordance with the calculated setting. Measuring at least one parameter reflecting a temperature in the interior part of the nacelle. Adjusting the setting(s) for the conditioning unit(s) based on the measured parameter(s), and operating the conditioning unit(s) in accordance with the adjusted setting(s). The setting(s) is/are initially calculated based on the historical, statistical and/or forecast data, thereby providing a qualified starting point. The setting(s) is/are then adjusted or fine tuned on the basis of actual temperatures of the nacelle, thereby taking these into account and reaching optimal setting(s) quickly. An artificial intelligence (AI) system may be used. The method may include control of temperature and/or humidity inside the nacelle and/or temperature of components arranged in the nacelle.

摘要： A speed setting system that generates a speed control command for controlling the rotational speed of a stall-controlled wind turbine of a wind-powered machine. The speed setting system generates the speed command as a function of performance variation of the wind turbine due to environmental and/or other factors. The speed setting system utilizes a performance-compensation term that is slowly adjusted to compensate for relatively long-term performance variation. In one example, the performance-compensation term is adjusted only when the current power output of the wind turbine is at least 80% of the rated output power to ensure the wind speed is sufficiently high.
