Anemometer tower site selection method and device

Abstract

The invention provides an anemometer tower site selection method and device, and the method comprises the steps: determining the terrain type of a wind power plant according to the elevation data of a field region of the wind power plant; according to the fan arrangement mode corresponding to the determined terrain category, determining a plurality of fan point positions used for arranging the wind generating sets in the wind power plant; and taking the plurality of determined fan point positions as anemometer tower alternative point positions, and determining an anemometer tower actual point position for arranging the anemometer tower in the wind power plant from the anemometer tower alternative point positions. By adopting the anemometer tower site selection method and device provided by the embodiment of the invention, the accuracy of anemometer tower site selection can be improved, powerful support is provided for accurate evaluation of regional wind resources, and the improvement of the accuracy of economic evaluation and power generation evaluation of a wind power plant is facilitated.

Description

technical field [0001] The present invention generally relates to the technical field of wind power, and more specifically relates to a method and device for site selection of an anemometer tower. Background technique [0002] The design of the wind measurement scheme is mainly based on the analysis of the terrain and wind parameters of the area where the planned wind farm is located, to select the location of the wind measurement tower and configure the equipment related to wind measurement. , through the numerical method, the accurate assessment of the distribution of wind resources in the field area is completed, which provides a reference for the design and economic evaluation of wind farms. [0003] At present, there are mainly two methods for wind measurement scheme design. One is that engineers complete the wind measurement scheme design work through subjective analysis based on geographical and meteorological environmental conditions, through human judgment, and subj...

Problems solved by technology

For complex terrain, it is difficult to accurately obtain data of multiple spatial grid points, which requires relying on mesoscale and CFD methods to calculate wind maps. This method has the advantage of high accuracy, but it also has high cost and long cycle The disadvantage is that the owner can hardly afford the cost before the wind measurement

If you only use mesoscale data, you need to obtain the grid point data of the wind map in the area of ​​interest. Currently, there is mesoscale grid point data with a horizontal spatial resolution of 200 meters. Due to the low spatial resolution of the mesoscale calculation method, the terrain cannot be captured Details, it is difficult to assess the impact of terrain on wind conditions, and the accuracy of most grid point data is low. Correlation analysis on this basis will lead to large deviations, which will eventually lead to deviations in the selection of wind measurement grid points

[0008] To sum up, there is currently no efficient automatic wind measurement scheme arrangement method available
