Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment of wind measurement data processing method based on wind direction sector:

[0026] This embodiment provides a wind measurement tower wind data processing method based on the wind direction sector, including the steps of calculating the tower shadow effect index, judging the influence degree of the tower shadow effect, and processing the wind speed data affected by the tower shadow effect. The corresponding flow chart is as figure 1 shown, including the following:

[0027] (1) First, calculate the tower shadow effect index.

[0028] The first step is to collect two-channel wind speed data at the same height of the anemometer tower, and divide the first-channel wind speed data VA and the second-channel wind speed data VB...

Abstract

The invention relates to an anemometer tower wind measurement data processing method and a device based on a wind direction sector. The method comprises the steps of collecting wind speed data of twochannels at the same height of an anemometer tower; calculating the ratio of the wind speeds of the two channels falling in the same sector at the same moment, counting each ratio of each sector, andcalculating a tower shadow effect index for all the sectors; and if the tower shadow effect index is greater than a set tower shadow effect threshold, processing the corresponding two-channel wind speed data in each sector. According to the method, quantitative analysis is carried out on the significant degree of the influence of the tower shadow effect on the anemometer tower anemometry data, theanemometry data can be processed only when the influence of the tower shadow effect on the anemometry data exceeds a certain degree, errors caused by improper processing of the tower shadow effect are avoided, and the authenticity of the anemometry data is guaranteed.

Description

technical field [0001] The invention relates to a method and device for processing wind measurement data of an anemometer tower based on wind direction sectors, and belongs to the technical field of wind force testing. Background technique [0002] Due to the influence of the wind measuring tower, after the airflow passes through the wind measuring tower, the flow field will inevitably change, which leads to the gap between the data collected and recorded by the wind measuring instrument and the real wind vector. Certain deviations. [0003] In order to obtain the influence information of the tower shadow effect on the wind measurement data, in practical engineering applications, two sets of wind speed sensors are generally installed at the same height and different orientations of the wind measurement tower to obtain two sequences of wind speed data. When the wind speed sensor is located in the downwind direction, the tower shadow effect is the most significant; when the w...
