摘要： A method of operating a wind turbine, wherein the wind turbine comprises a rotor (101) with two or more rotor blades (10). The method comprises detecting a load asymmetry of a load acting on the rotor (101), the load being caused by a flow of air to which the rotor (101) is exposed. It further comprises reducing the load asymmetry by controlling an active aerodynamic device (20), wherein the active aerodynamic device (20) is provided on a rotor blade (10) of the rotor (101), and wherein the active aerodynamic device (20) is controlled to change, based on the detected load asymmetry, an aerodynamic load applied to the rotor blade (10) by the flow of air to counteract the load asymmetry.

摘要： The invention relates to a method for computer-implemented monitoring of a wind turbine having a rotor with rotor blades (10). The rotor blades (10) are provided with an active flow control device (11D, 12D, 14D). During the operation of the wind turbine the following steps are performed:
i) obtaining digital operation data (OD) of the wind turbine, the operation data (OD) being current sensor data (WTSD) taken by a plurality of sensors installed on the wind turbine and a control signal (AFCD CS) for controlling the active flow control device (11D, 12D, 14D) to adopt a specific state;
ii) determining an estimate (ECLI) of the state and/or performance degradation of the active flow control device (11D, 12D, 14D) by processing the operation data (OD) by a trained data driven model (DDM), where the operation data (OD) are fed as a digital input to the trained data driven model (DDM) and the trained data driven model (DDM) provides the estimate (ECLI) of the state and/or performance degradation of the active flow control device (11D, 12D, 14D) as a digital output.

摘要： A system and method for pressure based load measurement are provided. The system and method measure at least one pressure differential on an airfoil and determine at least one aerodynamic load associated with the at least one pressure differential. The determined at least one load is used to modify characteristics of the airfoil to increase efficiency and/or avoid damage. The determined at least one aerodynamic load may be further utilized to balance and/or optimize loads at the airfoil, estimate a load distribution along the airfoil used to derive other metrics about the airfoil, and/or used in a distributed control system to increase efficiency and/or reduce damage to, e.g., one or more wind turbines.
