An Improved-Accuracy Method for Fatigue Load Analysis of Wind Turbine Gearbox Based on SCADA

In spite of their increasing popularity, managing the use of wind turbines has been exceptionally challenging. Through computational prognostics, Sentient Science determined that current operating lifetime for a large number of turbines is only between five to thirteen years. Initial estimates indicate that savings of $150,000 per turbine per gearbox replacement can be achieved using physics-based long-term prognostics, leading to a substantial return of investment for wind farm operators. However, long-term prognostics require a precise determination of the loads in all six degrees of freedom occurred on the drive-train.
