Failure preventive monitoring system for yaw devices used in wind turbines
The Condition Monitoring system with Fail-Safe (CMFS) and CMFS-based
diagnostic service help to prevent failure of wind turbines and prolong their life.

Preventing failure caused by excessive load imposed by turbulence/wind that blows upward

Turbulence/wind that blows upward causes the tower to vibrate, which could impose an excessive load on the yaw system.

Prolonging the life of large wind turbines in which multiple yaw drive units are used

The use of multiple drive units in a wind turbine has become a trend, but such use could impose an uneven load on the units, resulting in the generation of excessive load on some of them.
