Title:
ROTATING THREE-DIMENSIONAL ULTRASONIC ANEMOMETER, AND METHOD FOR MEASURING THREE-DIMENSIONAL WIND VELOCITY BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/009507
Kind Code:
A1
Abstract:
Disclosed are a three-dimensional ultrasonic anemometer, a three-dimensional wind velocity measurement method, and a wind turbine, according to various embodiments. The three-dimensional ultrasonic anemometer includes: three pairs of ultrasonic transmitters/receivers arranged in different directions; an ultrasonic sensor unit which is provided at a rotating body, which rotates around a rotational axis so as to rotate together with the rotating body around the rotational axis; a signal processing unit for outputting a three-dimensional sensing wind velocity (Us, Vs, Ws) which is sensed by the ultrasonic sensor unit; and a coordinate conversion unit for converting the three-dimensional sensing wind velocity (Us, Vs, Ws) into a three-dimensional fixed wind velocity (U, V, W) on a fixed coordinate system (X, Y, Z) by using a rotational angle (φ) of the rotating body, and outputting the same.
