Descripción
The accuracy of wind speed and direction measurements with spinning ultrasonic wind sensors is important than ever in today ? s wind industry in which, they are usually installed on the hub of the wind turbines to measure the wind speed and direction for optimized power. In this paper, extensive wind-tunnel tests have been performed to calibrate the wind speed and direction measured by a spinning single-axis ultrasonic anemometer for both static and spinning conditions. This has been carried out with static measures at various stationary angles of trans- ducers signal path with wind direction, and with dynamic measures in which the anemometer is rotating with various rotational speeds. The velocity measured by ultrasonic anemometer in static tests is calibrated with pitot- tube data, and the interpolation of obtained calibration coe ffi cients is used to correct the ultrasonic velocity measured in dynamic tests. It is observed that the calibrated ultrasonic wind speed measurements in dynamic tests are in a good agreement with the reference velocity. According to the results, the ultrasonic velocity measurements in both static and dynamic tests are a ff ected by the transducers head distortions, and the shifting in acoustic pulse trajectory due to the rotational motion does not a ff ect the anemometer measurements. The uncertainty of the calibration process for the spinning tests was found to be about 0.3%
