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.

Abstract:

Information associated with session flows between communication devices and servers is collected and shared. A request is generated for data having predefined attributes within session flows occurring between multiple communication devices and a server over a communication network. The request is sent to a controller having access to information indicating network elements within the communication network traversed by the session flows. The controller selects a network element from among the network elements traversed by the session flows and retrieves the data from the selected network element.
