Embodiment Construction

[0019] The present invention will be further described below through specific embodiments.

[0020] A quantitative analysis method for setting up a wind measuring tower, comprising the following steps:

[0021] A. According to the relevant data of the geomorphic environment near the wind farm to be built, collect the data of the built wind farm similar to its terrain;

[0022] B. Select the wind-measuring tower for analysis from the wind-measuring towers collected by the built wind farm, and select according to the wind energy resource status, the wind-measuring data time period and the positional relationship with the machine position;

[0023] C. Centering on the position of the selected anemometer tower for analysis, the main wind direction and the vertical main wind direction position within the wind farm range are respectively set up with multiple sections according to the different distances. At the same time, considering the terrain, select multiple sections on each sec...

Abstract

The invention discloses a quantitative analysis method for an establishment scheme of an anemometer tower in the technical field of a wind power technology. The method comprises the following steps of firstly, selecting the anemometer tower with analysis significance from an established wind power plant according to a wind energy resource situation, a wind measurement data time period and a position relation between the anemometer tower and a stand; then dividing the wind power plant into a plurality of cross sections on the basis of a prevailing wind direction and a vertical prevailing wind direction according to the position of the anemometer tower; then carrying out comparison analysis on actually measured data of the anemometer tower on different cross sections and power generation data of a wind power generator; and finally determining the representativeness of the anemometer tower under similar terrain conditions and providing a reference for other similar wind power plant sites with the representativeness as a reference standard. The method has the beneficial effects that the problem of post-evaluation of wind resources after a wind power plant project is put into production is well solved, representative analysis basis for the anemometer tower can be provided for a to-be-developed wind power plant in an adjacent and similar terrain region, a reference for establishment of a position of the anemometer tower is provided, and the method is good in practicability and application prospect.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a quantitative analysis method for an anemometer tower setup scheme. Background technique [0002] At present, the commonly used method for wind energy resource assessment of wind power projects is to set up wind measuring towers in the site area, and use wind energy resource assessment software (WT, wasp, etc.) to calculate wind energy resources in the entire wind farm area based on wind measuring tower data and terrain information distributed. In order to ensure the accuracy of wind energy resource assessment, multiple wind measuring towers should be set up within the scope of the wind farm site. Different wind measuring towers represent different areas, and all wind measuring towers should be able to cover the entire range of the wind farm. [0003] The layout of the wind measurement scheme of the wind farm is based on the designer's experience to determine the ...
