Presented at: European Wind Energy Conference and Exhibition (EWEC), Warsaw, Poland, 20-23 april 2010.

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.
