Problems solved by technology

[0003] At present, most of the research on terrain complexity is determined by judging the elevation difference and elevation change rate within a certain area. This kind of terrain complexity research only describes a single feature of terrain complexity, and does not combine wind farms and wind turbines. Considering the relationship between wind direction, topography and topography in the special situation of the distribution, it is not suitable for the site selection in the early stage of wind farm construction.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, in particular, the present invention relates to a method, device and equipment for determining the topographical complexity of a wind power generating set point. Background technique [0002] The wind power industry needs to model and simulate the geographical environment of the study area when conducting macro- and micro-site selection of wind farms. Terrain and landform data are important data inputs for modeling, and their accuracy greatly affects the final results. evaluation accuracy. In the pre-planning process of wind farms, it is necessary to estimate the terrain complexity of the wind farm area to determine the difficulty of later construction or the location of wind turbines. [0003] At present, most of the research on terrain complexity is determined by judging the elevation difference and elevation change rate within a certain area. This kind of terrain complex...
