Title:
METHOD FOR DETERMINING DATA AVERAGE WIND SPEED VALUE POINT POSITION IN CROSS SECTION OF NON-UNIFORM WIND FIELD WIND DUCT
Document Type and Number:
WIPO Patent Application WO/2024/082760
Kind Code:
A1
Abstract:
A method for determining a data average wind speed value point position in the cross section of a wind duct. By providing a big data wind volume measurement dynamic sensing device wind volume flowmeter at the cross section of a wind duct, for a control monitoring analysis unit A, preset point positions are uniformly distributed in the cross section of the wind duct in all directions, wind volume of each preset point position under a monitored load value is measured, and a data average value under the monitored load value is separately calculated: wind speed values of all preset point positions under the monitored load value are separately accumulated and then divided by the number of the preset point positions; a set wind duct data average wind speed error value is gradually increased until at least one preset point position under the monitored load value falls within a set wind duct data average wind speed error value range, i.e., the preset point position is a data average wind speed value point position of the wind duct. In this way, the wind volume flowmeter is only provided at the data average wind speed value point position to measure the wind speed in the wind duct, such that a data average wind speed value of the cross section of the wind duct represents an actual cross-sectional wind speed, thereby solving the problem in the prior art of inaccurate wind volume measurement.
