Measurement Uncertainty Evaluation of Torque Measurements in Nacelle Test Benches

• Abstract:

  Torque measurement in the MN·m range is important in nacelle test benches, as it constitutes a main value for the efficiency determination of wind turbine drive trains. However, no traceable measurement is possible above 1.1 MN·m. At the moment, alternatives to direct torque measurement in the MN·m range are, therefore, used. Several of these torque measurement methods are presented and discussed in this paper with respect to traceability and measurement uncertainty. As these methods cannot substitute direct measurements fully, recommendations for a calibration procedure are given to enable a calibration of torque measurement using a torque transfer standard.
