Presented at: European Wind Energy Conference and Exhibition (EWEC), Warsaw, Poland, 20-23 april 2010.
Abstract:
The reliability of mechanical components of wind
turbines needs to be improved. In the PROTEST
project, a pre-normative project, complementary
procedures are developed to improve the
specification of the design loads at the interfaces
where the mechanical components (pitch and
yaw system as well as the drive train) are
attached to the wind turbine. This has resulted in
a suggestion for three new DLC’s that are mainly
due to the limitations of the current day tools.
Next to this, a new approach of how to set up
and use the prototype measurement campaign
has been created. This approach consists of six
steps that need to be taken in order to validate or
improve the models used for the design of the
mechanical components. This new approach is
illustrated using the pitch system as an example.
In this example the focus is on the friction in the
pitch bearing, which is calculated and compared
to measurements.
