AB - A technique for measuring wind speed and direction by using a roll-rotating three-axis ultrasonic anemometer was proposed and verified by wind tunnel tests. The test conditions were chosen to cover the operational range of typical wind turbines. The results of measuring the roll-rotating three-axis ultrasonic anemometer were converted on a fixed-roll axis and compared with those of a non-rotating anemometer. As a result, the residual errors that remained after axis transform were within the anemometer accuracy except for an RMS error of wind speed at yaw 30°. But at yaw 0°, it was reduced within the anemometer accuracy. This roll-rotating measuring technique was successful regardless of rotating speed, wind speed, and sampling rate. In order to use this rotating measuring technique as a spinner anemometer for wind turbines, the effect of the spinner has to be considered. Theoretically, the effect of the spinner amplifies the wind direction along the rotational axis and the measured flow direction is larger than the incoming wind direction. This trend seems to be favorable for yaw control if wind direction is measured during yaw motion and feedback to yaw control.

초록

A technique for measuring wind speed and direction by using a roll-rotating three-axis ultrasonic anemometer was proposed and verified by wind tunnel tests. The test conditions were chosen to cover the operational range of typical wind turbines. The results of measuring the roll-rotating three-axis ultrasonic anemometer were converted on a fixed-roll axis and compared with those of a non-rotating anemometer. As a result, the residual errors that remained after axis transform were within the anemometer accuracy except for an RMS error of wind speed at yaw 30°. But at yaw 0°, it was reduced within the anemometer accuracy. This roll-rotating measuring technique was successful regardless of rotating speed, wind speed, and sampling rate. In order to use this rotating measuring technique as a spinner anemometer for wind turbines, the effect of the spinner has to be considered. Theoretically, the effect of the spinner amplifies the wind direction along the rotational axis and the measured flow direction is larger than the incoming wind direction. This trend seems to be favorable for yaw control if wind direction is measured during yaw motion and feedback to yaw control.
