Abstract
The present disclosure is directed to a system and method for estimating an overall wind coherence acting on a wind turbine and using same to dynamically adapt the gain or bandwidth of pitch or torque or yaw control logic within a wind turbine. The method includes generating, via sensors, a plurality of sensor signals reflective of wind conditions near the wind turbine. The method also includes filtering, via at least one filter, the sensor signals at a predetermined frequency range considered damaging for turbine sub-system loading. Thus, the method also includes estimating an overall damaging wind coherence acting on the wind turbine as a function of distance-normalized wind coherences, which themselves are derived from auto and cross-covariances of pairs of filtered signals. The distance normalization uses a model of natural coherence dissipation with distance.
