Short summary
Drivetrain efficiency is a wind turbine’s fundamental behaviour in the energy conversion. To determine the efficiency, input and output powers need to be measured with sufficient accuracy. However, this is a very challenging task due to high complexity and lack of properly calibrated torque measurements. In cooperation with the German and Swiss national metrology institutes, the efficiency determination with state-of-the-art instrumentations is demonstrated here with test processes and results.
