Abstract:
The measurement of mechanical power in nacelle test benches is an essential part of determining the efficiency of wind turbines. For this purpose, the selected inclinometer is integrated into the torque transfer standard to build a transfer standard for mechanical power measurement. The metrological characteristics of rotational speed measurement using the inclinometer are investigated by considering the static calibration, the uncertainty contributions due to mounting misalignments, eccentricity, dynamic effects, and the process of data evaluation. Finally, the traceability chain of the rotational speed measurement is established.
