Problems solved by technology

[0002] In recent years, people have carried out a lot of work on the measurement and evaluation of wind energy resources in complex terrain, summed up some experience, put forward some requirements and principled constructive suggestions, but there are still many deficiencies, such as the lack of classification indicators for wind farms In the division of wind zones, it is impossible to clearly determine the representativeness of the location of the wind measuring tower, and the number of wind measuring towers cannot be clearly determined. The operability is not strong, and it is often difficult for inexperienced staff to start

Embodiment 1

[0054] A method for dividing a wind area of ​​a wind farm, the steps of which include:

[0055] 1) Select the initial wind measurement data of the wind farm

[0056] Select wind farm general survey wind measurement data, if there is no general survey wind measurement in the wind farm, use the wind measurement data of the wind farm adjacent to the wind farm, or use the high-altitude wind energy resource simulation data of the wind farm;

[0057] 2) Preliminary analysis of wind energy resources in wind farms

[0058] Using the initial wind measurement data of the wind farm, the wind energy resource analysis software is used to analyze the wind energy resources of the wind farm and the map calculation; when the wind farm is flat terrain, the WindFarmer wind energy resource analysis software is selected to perform the wind energy resource analysis and map calculation of the wind farm; When the wind farm is on uneven terrain, WT wind energy resource analysis software is selected f...

Embodiment 2

[0114] The present invention also includes a method for selecting the location of a wind farm wind measuring tower, the steps of which include:

[0115] 1) Calculate the simulated annual average wind speed matrix and calculate the average annual average wind speed of each simulated tower position

[0116] For each wind area screened by the embodiment, there is a Y×Y matrix formed by simulating the annual average wind speed at other simulated wind tower positions with each simulated wind measuring tower, and there is an average value corresponding to each column, and this value is called the Simulate the average value of the annual average wind speed at the tower site, and use this value as an approximate estimate of the actual measured value of the annual average wind speed at the tower site;

[0117] 2) Calculate the annual average wind speed deviation matrix

[0118] The difference between the annual mean wind speed value of each column in the Y×Y matrix and the mean value ...

Abstract

The invention discloses a wind power field wind region division method. The wind power field wind region division method comprises steps that 1), the wind power field initial wind detection data is acquired; 2), preliminary analysis on wind power field wind energy resources is carried out; 3), simulation wind detection towers are distributed; 4), the wind detection data of the simulation wind detection towers is acquired; 5), an average annual wind speed matrix of the position of the simulation wind detection towers is calculated; 6), wind region division indexes are primarily acquired; 7), an average annual wind speed amplitude absolute error matrix is calculated; and 8), adjacent simulation wind detection tower wind regions are merged. The invention further discloses a method for selecting the wind detection tower position of the wind power field wind regions. The method is applicable to wind detection on wind power fields under complex mountain terrains in wind power industries home and abroad, strong applicability is realized, and blanks in selecting the wind detection tower quantity at a wind detection stage and distributing the wind detection towers of the wind power fields are filled.

Description

technical field [0001] The invention belongs to the technical field of wind areas of wind farms, and in particular relates to a method for dividing wind areas of wind farms with complex terrain. The invention also relates to a method for selecting the position of an anemometer tower in a wind farm. Background technique [0002] In recent years, people have carried out a lot of work on the measurement and evaluation of wind energy resources in complex terrain, summed up some experience, put forward some requirements and principled constructive suggestions, but there are still many deficiencies, such as the lack of classification indicators for wind farms In the division of wind zones, it is impossible to clearly determine the representativeness of the location of the wind measuring tower, and the number of wind measuring towers cannot be clearly determined. The operability is not strong, and it is often difficult for inexperienced staff to start. Contents of the invention ...
