Wind measuring method, system and device suitable for large-scale wind power base and storage medium

Abstract

The invention discloses a wind measuring method, system and device suitable for a large-scale wind power base and a storage medium. The wind measurement method comprises the steps of: selecting n windmeasurement points in a wind power plant according to the area of the wind power plant, wherein n is an integer larger than 2; dividing at least part of the wind measurement points in the n wind measurement points into m groups according to geographical positions, and arranging laser radar in each group, wherein m is an integer greater than 1; during the preset wind measurement time, performing circular wind measurement at each wind measurement point in each group by using one corresponding laser radar to obtain discontinuous radar wind measurement data corresponding to each wind measurementpoint; and performing interpolation on the discontinuous radar wind measurement data corresponding to each wind measurement point to obtain continuous interpolated radar wind measurement data of eachwind measurement point in the preset wind measurement time period. According to the method, the coverage of the wind measurement can be ensured, the huge cost caused by the fact that a plurality of wind measurement towers required being erected is effectively reduced on the premise that the representativeness of the wind measurement data is good, and the accuracy of wind resource evaluation is ensured.

Description

technical field [0001] The invention belongs to the field of wind resource detection in wind farms, and in particular relates to a wind measuring method, system, equipment and storage medium suitable for large-scale wind power bases. Background technique [0002] In order to accurately estimate the rate of return of wind power projects and ensure project profitability, it is necessary to ensure that the wind resource status of the entire site is accurately obtained in the early stage of wind measurement. Due to the large area and wide coverage of large-scale wind power bases, there may be large spatial differences in wind resources in different regions of the wind farm. The traditional wind measurement scheme is to select representative points in the wind farm area to establish wind measurement towers for fixed-point wind measurement. Each wind measurement tower represents the wind resources within a certain range around it. Meteorological masts capture wind resource condit...
