Diagnostics of bearings in presence of strong operating conditions non-stationarityA procedure of load-dependent features processing with application to wind turbine bearings
Analysis of long term diagnostic data (RMS and peak to peak of vibration) from online monitoring system. Generator power  dependent diagnostic data. Feature  operating condition space for cancellation of influence of wind power variability to vibration features. Statistical processing of data in moving window. Novel stable, load-independent and fault sensitive features for decision making.
