In wind energy operations, the reliability of the non-drive-end (NDE) bearing is fundamental to ensuring rotor stability at ~1500 RPM and safeguarding the generator shaft and drivetrain. Even slight bearing degradation can disrupt generator speed and power stability, threatening both asset availability and revenue generation in highly competitive renewable markets.
In this case, the turbine began showing subtle early deviations, such as the bearing temperature climbing above 75 °C, spikes in vibration acceleration, and correlated dips in generator speed and reactive power. These minor anomalies, often missed by conventional predictive analytics solutions, were immediately detected by the UptimeAI Expert platform:
- Rising NDE bearing temperature above advisory threshold
- Vibration increase to nearly 1.8 mm/s
- Correlation with abnormal generator speed and power swings
Learn how the plant team, guided by UptimeAI’s prescriptive recommendations, were able to connect the dots to identify roller-element wear weeks in advance. Then, during a scheduled downtime event, the team planned the bearing replacement, and ultimately avoided 169 MWh of lost clean energy and 151 hours of downtime
