摘要： A wind turbine comprises a rotor (10), a rotor hub (100), a transducer for measuring a displacementof a component of the turbine structure caused by asymmetric loads acting on the rotor, and a fixed supporting shaft (105) which supports the rotor atthe rotor hub. Said transducer comprises at least one strain-gauge sensor arranged for measuring a deformationof the fixed supporting shaftdue to asymmetric loads acting on the rotor. A computation system receives signals from one or more sensors and, based on the value of said signals, calculates at least one component of the asymmetric loads. The computation system commands actuators for individually setting the pitch of each blade of the turbine, in order to mitigate the asymmetric loads endured by the rotor.

摘要： A control system for a wind turbine comprises: a sensor arrangement (B, E, H) for capturing measures related to the turbine operation and fatigue accumulation; an upper level controller (U), which, on the basis of a statistical treatment of said measures, calculates optimized control settings at discrete points of time; a measurement module (F) which processes said measures into instantaneous values, and a lower level controller (L) that receives said control settings and said instantaneous values and calculates instantaneous optimal commands to control turbine actuators (G). The lower level controller comprises a continuous-time damage model (V) which calculates the rate at which damage is accumulated at any time, and an optimal controller (X) which controls operational states of the turbine, either by directly feedbacking the instantaneous values to the actuators, or by generating a turbine performance objective function which is continuously optimised by repeatedly solving a receding horizon optimization problem.
