Reduce yaw failures
Why do yaw systems fail?
- Misalignment – variation in backlash (distance between gear teeth flanks in a mesh) either in setup or through wearing of the gear and pinion
- Maintenance – poor maintenance of braking and lubrication systems
- High winds and cross winds – winds that deviate from the current yaw position increase the moment (turning force) of the nacelle which strains the yaw system
How can CMS help?
Usually, CMS can predict failures, providing warning months in advance, allowing time for maintenance and component replacement scheduling to minimise wind turbine downtime. Nab Tesco’s condition monitoring with fail-safe (CMFS) uses bolt strain sensor data to prevent overload by feathering the yaw brake. This action reduces fatigue and failures on the yaw gear.
1. Install bolt sensors
The strain sensors detect the amount of strain and directly measures the load applied to the yaw device unit
2. Measure the data
Convert the data with a signal converter
3. Control the braking
The control box allows integration of the strain limits into the braking system
4. Manage and reduce loads
Measurement of the loads allows failure predictive and the control system shares the loads evenly between yaw drives
Reduce WTG downtime
Reduce the cost of failures
Extend the life of yaw systems
Remaining useful life prediction
