Embodiment Construction
[0039] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0040] According to an embodiment of the present invention, such as Figure 1-Figure 10 As shown, a method for statistical analysis of wind tower coverage is provided, which mainly includes:
[0041] a. Select a wind measuring tower in the area to be measured as the wind measuring tower to be calculated;
[0042] b. Through the measured wind speeds of other wind measuring towers in the area to be measured, respectively calculate the wind speed of the wind measuring tower to be calculated, and analyze whether the wind speed at the position of the wind measuring tower to be calculated can be determined by the measured wind speed of other wind measuring towers obtaine...

The invention discloses a coverage statistical analysis method for anemometer towers. The coverage statistical analysis method mainly includes steps of selecting one of the anemometer towers in a to-be-measured area as an anemometer tower to be calculated; measuring wind speed of other anemometer towers in the to-be-measured area in real time, respectively calculating the wind speed of the anemometer tower to be calculated, and analyzing whether the wind speed at the location of the anemometer tower to be calculated can be acquired by calculating the real-time wind speed of the other anemometer towers or not; determining resolution ratio of an anemometry network corresponding to the to-be-measured area according to an analysis result acquired after calculating whether the wind speed at the location of the anemometer tower to be calculated can be acquired by calculating the real-time wind speed of the other anemometer towers or not. The coverage statistical analysis method can overcome the defects of small application range, low site selecting efficiency, high construction cost and the like in the prior art, and has the advantages of large application range, high site selecting efficiency and low construction cost.
Description
technical field [0001] The invention relates to the technical field of wind resource monitoring in the process of wind power generation, in particular to a statistical analysis method for the coverage of an anemometer tower. Background technique [0002] Most of the large-scale wind power bases generated after my country's wind power enters the stage of large-scale development are located in the "Three North Regions" (Northwest, Northeast, and North China). Large-scale wind power bases are generally far away from the load center, and their power needs to be transmitted to the load center through long distances and high voltage. To digest. Due to the intermittence, randomness and volatility of wind resources, the wind power output of large-scale wind power bases will fluctuate in a large range, which will further lead to fluctuations in the charging power of the transmission network and bring a series of problems to the safety of power grid operation. [0003] As of November ...
