Embodiment Construction

[0009] The technical solution of the present invention will be further described in detail below according to the drawings in the description and in combination with specific embodiments.

[0010] see figure 1 , the method for obtaining the distribution of wind resources that can generate electricity provided by the present invention mainly includes the following steps:

[0011] Step S10, assuming that there are N wind measuring towers in the wind power base, and obtaining each wind measuring tower Historical wind speed data for the first M hours;

[0012] Step S20, performing the shortest distance clustering on the wind measuring towers according to the correlation of the wind speed data in the previous M hours at each full hour;

[0013] Step S30, calculate the point to be sought and all wind measuring towers geographic distance ;

[0014] Step S40, find the geographic distance smallest wind tower ;

[0015] Step S50, according to the calculation results of step...

Abstract

The invention provides a method for obtaining distribution of wind resources capable of power generation. The method mainly comprises the following steps: step S10, obtaining historical wind speed data of previous six hours of each wind measuring tower; step S20, at each full hour time point, according to wind speed data correlation of the previous six hours, performing clustering on the wind measuring towers; step S30, assuming that there are n wind measuring towers at a wind power base, calculating a geographical distance Ri between a to-be-calculated point and all the wind measuring towers Ti(i=1,2, ..., N); step S40, finding a smallest wind measuring tower Ti(i=1,2, ..., N) of the Ri; step S50, according to calculation results in the step S20 and the step S40, determining other wind measuring towers in a group which a wind measuring tower Ti belongs to; and step S60, carrying out interpolation on selected wind measuring towers by use of an inverse distance weighting method to obtain wind speed and wind direction estimation values of known points.

Description

technical field [0001] The invention belongs to the field of wind resource analysis of large-scale wind power bases, and relates to a method for calculating the distribution of wind resources that can generate electricity, in particular to a method for calculating the distribution of wind resources that can generate electricity for wind power bases with tens of millions of kilowatts. Background technique [0002] The distribution endowment of natural resources in my country determines that most of the large-scale wind power bases are located in areas far away from the load center and without large-scale power source support. The large-scale wind power centralized grid connection leads to large fluctuations in the power of transmission lines, which poses a huge challenge to the safe and stable operation of the power system. Because the construction speed of wind farms is generally faster than that of power grids, under the background of large-scale and high-speed development o...
