Precision Turbine Shaft Alignment | Wind Systems

Precision shaft alignment is the process of aligning the centerline of the shafts of one or more rotating machines. When the shaft centerlines are co-linear they can turn freely, and the external forces that

Determination of optimal wind turbine alignment into the

Current methods to detect a change in the alignment of turbines are based on wind direction in-situ comparison in case of redundancy of the device on the nacelle or by comparing wind

Wind Turbine Alignment in High Winds

Precision alignment of the generator to the gearbox in a wind turbine (the high speed shaft) is critical to proper operation. 60 percent of wind turbine downtime is related to drive train failure: gearbox, generator, main

6 FAQs about [Wind turbine generator alignment process]

How is wind turbine alignment done?

Wind Turbine Alignment is normally done by treating the gearbox as the stationary machine, and the generator as the moveable machine. The misalignment is measured almost exclusively with a laser shaft alignment tool.

Do wind turbines need to be aligned?

Precision alignment is recommended by most wind turbine manufacturers for optimal operation and reliability. Generator efficiency can also be affected by misalignment (angular and offset). The following questions—and answers—will help you to enhance the productivity and longevity of your turbine. What needs to be aligned in a wind turbine?

How long does it take to align a wind turbine?

The first turbine was aligned early in the morning in moderate wind speeds of approx. 2-5 m/s, the alignment went smoothly and we completed the alignment in about 45 minutes with excellent alignment results. The second turbine proved to be challenging. After lunch, the wind had picked up a little but was still acceptable.

Why should a wind turbine shaft be aligned?

Properly aligned shafts are able to spin freely and not induce other unwanted forces to the system. These unwanted forces will damage and/or destroy bearings, seals, and couplings, and eventually the gearbox or generator. Precision alignment is recommended by most wind turbine manufacturers for optimal operation and reliability.

How difficult is it to align turbine-generator sets?

The alignment of turbine-generator sets poses unique challenges that only the best laser shaft alignment systems can overcome. Not the least of these is the difficulty of turning the shafts (either coupled or uncoupled) and the methods employed in turning them.

What happens if a wind turbine is misaligned?

These unwanted forces will damage and/or destroy bearings, seals, and couplings, and eventually the gearbox or generator. Precision alignment is recommended by most wind turbine manufacturers for optimal operation and reliability. Generator efficiency can also be affected by misalignment (angular and offset).
