Title:
METHOD AND APPARATUS FOR DYNAMICALLY DETERMINING YAW CONTROL PRECISION
Document Type and Number:
WIPO Patent Application WO/2019/165752
Kind Code:
A1
Abstract:
A method and an apparatus for dynamically determining yaw control precision. The method comprises: during a predetermined time period, collecting a plurality of wind speed data and a plurality of wind direction data, and processing the collected plurality of wind speed data and plurality of wind direction data; on the basis of the processed wind speed data and wind direction data, establishing a model of the corresponding relationship between wind speed, wind direction angle change, yaw control precision, yaw fatigue, and power loss; and, on the basis of the current wind speed data, wind direction data, predetermined yaw fatigue range, and predetermined power loss range, by means of the corresponding relationship model, determining the yaw control precision corresponding to the current wind speed and current wind direction angle change.
