Abstract: |
Precise torque measurement in multi-MW nacelle test benches (NTBs) is crucial
for the effciency determination of wind turbines. However, because the torque transducers of
NTBs are not yet traceable to national standards, their accuracy is not yet known. To rectify
this, a calibration procedure was developed for torque M under rotation using a torque transfer
standard. The results of measurements performed on an NTB are presented for a validation
and adjustment of the method planned. Dierent inuences on the calibration measurements
are discussed, such as static and rotational zero point determination, rotational speed n, and
ambient conditions. |
