Wind power plant early-stage anemometer tower planning and site selection method, system and device and storage medium

Abstract

The invention discloses a wind power plant early-stage anemometer tower planning and site selection method, system and device and a storage medium, and the method comprises the steps: obtaining the alternative positions of an anemometer tower through digital elevation data, and calculating the wind speed and wind direction sequences corresponding to the remaining alternative positions of the anemometer tower according to a contour line topographic map, reanalysis data and 30m-resolution surface roughness data; and obtaining the alternative position of a to-be-selected anemometer tower through the correlation, error analysis and the prevailing wind direction, determining that the position of the to-be-selected anemometer tower is effective by using a three-dimensional model, and determining the height of the anemometer tower according to the comprehensive wind shear. According to the method, the precision of planning and site selection of anemometer towers of a wind power plant in the medium complex terrain is improved, a basis is provided for determining the number of the anemometer towers, and fund waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power equipment construction, and in particular relates to a method, system, device and storage medium for early-stage wind measurement tower planning and site selection of wind farms adapted to moderately complex terrain. Background technique [0002] my country has a vast territory and abundant reserves of wind energy resources. With the advancement of wind turbine technology and the reduction of development and construction costs, wind farms with moderately complex terrain such as low mountains and hills have ushered in the peak period of development and construction. [0003] The development and construction conditions of low-mountain hilly wind farms are relatively complex, the altitude difference is large, the vegetation in some areas is dense, the terrain is rugged, the local climate is significant, and the spatial distribution of wind energy resources is quite different. Project development ...
