Abstract
A technique for performing condition monitoring of a plurality of components of a plurality of wind turbines is disclosed. The technique includes, for each of the plurality of wind turbines, measuring at least one time-series electrical output signal of the wind turbine generator, each time-series electrical output signal representing an aggregate of a plurality of subset signals. Such condition monitoring further includes mathematically extracting one or more such subset signals from the at least one time-series electrical output signal of the generator, and associating one or more such subset signals with one or more wind turbine components. A fault threshold value for each such one or more subset signals may be determined, and the one or more such subset signals are compared to such fault threshold value. Based on such association and comparison, the condition of such a wind turbine component of the plurality of wind turbines is determined.
