Abstract:
1. A computer-based method for use in predicting a wind turbine component failure, said computer-based method comprising: determining, at a computing device, a parametric profile for a component of a wind turbine from operating data of a plurality of wind turbines, the parametric profile defining at least one parametric event associated with the component prior to failure of the component; determining, at the computing device, an anomaly profile for the component of the wind turbine from anomaly alerts from a plurality of wind turbines, the anomaly profile defining at least one anomaly associated with the component prior to failure of the component; and, determining a probability of failure for the component of the wind turbine based on the parametric profile and the anomaly profile wherein the anomaly alerts are generated when a component parameter falls outside of an expected range.
