Abstract

Abstract: The spinner anemometer can measure the wind velocity in front of rotor by ultrasonic wind sensors mounted on the spinner. To estimate the undisturbed wind speed in far upstream, the detail calibration is required. This study proposes the wind speed measurement by pressure sensors mounted on the spinner as a new technology. The inflow wind speed and the inflow angle are estimated with the pressure sensors mounted on a spinner. The performance of wind speed measurement is evaluated by wind tunnel measurements with a model HAWT. The measured wind speed by stagnation and static pressures show good agreements between reference wind tunnel speed and accuracy of measured wind speed was assessed.
