CMFS for Wind Turbine Pitch and Yaw
During pitch rotation, repeated loads are applied as the system adapts to changing wind conditions; as wear and deterioration progress,...
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.
