Title:
WIND DIRECTION CORRECTION DEVICE, MODEL GENERATION DEVICE, CORRECTION METHOD, MODEL GENERATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/153525
Kind Code:
A1
Abstract:
This wind direction correction device (50) corrects a result of measurement by an anemoscope provided to a wind power generation apparatus. The items measured by the anemoscope include relative wind direction, which is the direction of wind with reference to the wind power generation apparatus, and wind speed . A past record acquisition unit (530) acquires an air density parameter related to the air density in the surroundings of the wind power generation apparatus, the wind speed measured by the anemoscope, and the direction of a nacelle of the wind power generation apparatus. A correction amount determination unit (540) determines a correction parameter for correcting the relative wind direction and/or the absolute wind direction by using the air density parameter, the wind speed, and the direction of the nacelle. When doing so, the correction amount determination unit (540) uses a conversion model in which input data including the air density parameter, the wind speed, and the direction of the nacelle is converted to the correction parameter.
