WIND FARM> Burgos, Spain> Size of the wind farm of 68 MW> 20 onshore turbines
WIND TURBINE> Onshore wind turbine> 3.4 MW wind turbine> Hub height of 110 m> Rotor diameter of 130 m> Pitch bearing diameter of 2.7 m
> REQUIREMENTS - The desired time to implement the idea must be short - The wind farm must remain in operation working with a high confidence level - The new pitch bearing reparation and stiffening solution must fulfil the loading, environmental, cost and structural specifications defined
> OBJECTIVE - To verify lifetime extension and reliability evaluation of the new lifetime extension concept for pitch bearings. - To verify the new lifetime extension concept viability for stiffening and/or reparation in pitch bearings. - To verify the suitability of the hybrid testing methodology during validation process of novel lifetime extension concepts for pitch bearings with respect to the current processes.
Dykes, (2019) IEA Wind Task 37
The new pitch bearing lifetime extension concept must fulfil the loading, environmental and structural specifications defined for the extension of lifetime in already installed wind turbines.
> PROBLEMS - The need of retesting the components for assuring longer lifetimes is a problem for the manufacturers - When there is a failure of the component in use (e.g. Ring structural fatigue (RSF) failure mode) the replacement of the component can be difficult
