[0053] The present invention is a solution to determine the most probable windward-side fan segment of the indirect air-cooled tower in a complex building environment. By obtaining the measured incoming wind speed and direction values of each fan segment under the annual condition, the actual incoming wind angle of each fan segment is obtained, and the occurrence times of the minimum value of the actual incoming wind angle of each fan segment are counted and the radial average wind speed of the fan segment is calculated.

At the same time, it also provides theoretical support and experimental numerical reference for the anti-freezing transformation of each cooling triangle unit of the indirect air-cooled tower.

[0054] To better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more clear and thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0055] Specifically, the present invention provides a method for determining the fan section on the windward side with the highest probability of an indirect air cooling tower, which includes:

[0056] S1. Obtain the incoming wind direction, incoming wind speed, and windward incoming wind angle of each fan section of the indirect air cooling tower under the annual operating conditions.

[0057] Figure 2 It is a specific flow schematic diagram of step S1 of a method for determining the fan section on the side of the indirect air cooling tower with the highest probability provided by the present invention. As Figure 2 shown, step S1 includes:

[0058] S11. Determine the windward incoming wind angle of each fan section based on the annual wind direction frequency diagram of the location where the indirect air cooling tower is located and the position information of each fan section.

[0059] Divide the windward incoming wind angles of the 1st to nth fan sections according to the annual wind direction frequency diagram of the location where the indirect air cooling tower is located. The windward incoming wind angle of the 1st fan section is α 1 ~α 2 、The windward incoming wind angle of the 2nd fan section is α 1 ~α 2 ……The windward incoming wind angle of the nth fan section is α n ~α 1 .

[0060] S12. Obtain the incoming wind direction and incoming wind speed of each fan section under the annual operating conditions through multiple anemometers and wind vanes. Install an integrated anemometer and wind vane at the incoming wind midline of each of the 1st to nth fan sections of the indirect air cooling tower. The integrated anemometer measures the incoming wind speed v and incoming wind direction α of the 1st to nth fan sections in real time every m (1≤m) seconds under the annual operating conditions.

[0061] S2. Determine whether the incoming wind direction of each fan section is within a preset range. If the incoming wind direction is not within the preset range, delete the data and output the result, that is, after deleting the data, this data does not participate in the calculation, and directly iterate to the next set of incoming wind direction values for calculation. Among them, the preset range is 0° to 360°.

[0062] S3. If the incoming wind direction is within the preset range, obtain the actual incoming wind angle of each fan section according to the incoming wind direction and the windward incoming wind angle.

[0063] Figure 3 It is a specific flow schematic diagram of step S3 of a method for determining the fan section on the side of the indirect air cooling tower with the highest probability provided by the present invention. As Figure 3 shown, step S3 includes:

[0064] S31. Obtain the inlet air angle of each sector by calculating the difference between the average value of the inlet air direction and the average value of the windward inlet air angle of each sector. According to the annual wind direction frequency diagram of the location where the indirect air cooling tower is located and the position information of each sector, the value range of the windward inlet air angle of each sector can be determined. The windward inlet air angle range of each sector has an upper limit value and a lower limit value, and the average value of the windward inlet air angle is the average value of the windward inlet air upper limit value and the windward inlet air lower limit value.

[0065] S32. If the inlet air angle is not greater than 180°, use the obtained inlet air angle as the actual inlet air angle of each sector.

[0066] S33. If the inlet air angle is greater than 180°, the actual inlet air angle of each sector is the angle obtained by subtracting the inlet air angle from 360°.

[0067] In the above steps, the difference between the inlet air direction α of the 1st to nth sectors of the indirect air cooling tower and the average value of the windward inlet air angles of each sector is the inlet air angle β r , if the inlet air angle β r ≤180°, the actual inlet air angle β of each sector = β r ; if the inlet air angle β r >180°, the actual inlet air angle β of each sector = 360° - β r ; the value range of the actual inlet air angle β of the 1st to nth sectors is 0° ≤ β ≤ 180°.

[0068] S4. Obtain the radial average wind speed of each sector by calculating the cosine value of the actual inlet air angle and combining it with the inlet air speed.

[0069] Figure 4 This is the specific process schematic diagram of step S4 of a method for determining the most probable tower-side sector of an indirect air cooling tower provided by the present invention. As Figure 4 shown, step S4 includes:

[0070] S41. Calculate the cosine value of the actual inlet air angle based on the actual inlet air angle of each sector.

[0071] S42. Obtain the radial average wind speed of each sector by calculating the product of the inlet air speed and the cosine value of the actual inlet air angle.

[0072] The product of the inlet air speed v and the cosine value of the actual inlet air angle cosβ of the 1st to nth sectors under the annual operating conditions of the indirect air cooling tower is the radial average wind speed, that is

[0073] S5. Determine the most probable windward side sector of the indirect air cooling tower based on the actual inlet air angle and the radial average wind speed of each sector.

[0074] Figure 5Schematic diagram of the specific process of step S5 of a method for determining the most probable tower-side fan section of an indirect air-cooled tower provided by the present invention, as shown in Figure 5 shown. Step S5 includes:

[0075] S51. Obtain the minimum actual inlet air angle of each fan section and the number of times the minimum actual inlet air angle appears. After the actual inlet air angles of the 1st to nth fan sections, count the number of times the minimum actual inlet air angles of the 1st to nth fan sections of the indirect air-cooled tower appear under the annual operating conditions.

[0076] S52. Determine the windward probability of each fan section based on the magnitude of the actual inlet air angle of each fan section, the number of times the minimum actual inlet air angle appears in each fan section, and the magnitude of the radial average wind speed of each fan section.

[0077] S53. Determine the most probable windward-side fan section of the indirect air-cooled tower based on the judgment result.

[0078] Furthermore, the fan section that satisfies the most of the following conditions is the most probable windward-side fan section: the minimum actual inlet air angle, the largest number of times the minimum actual inlet air angle appears, and the largest radial average wind speed. That is, the fan section with the largest number of windward-side appearances among the 1st to nth fan sections of the indirect air-cooled tower is preferably the windward fan section, the fan section with the largest cosine value of the actual inlet air angle among the 1st to nth fan sections is preferably the windward fan section, and the fan section with the largest radial average wind speed among the 1st to nth fan sections is preferably the windward fan section.

[0079] In a specific embodiment, the above scheme is described with the operating conditions of the indirect air-cooled tower in June. The specific implementation process is as follows:

[0080] First, for a natural draft indirect air-cooled tower of a 1000MW unit, according to the local prevailing wind direction where the indirect air-cooled tower is located, combined with the original position distribution of each fan section of the indirect air-cooled tower, divide the windward inlet air angles of the 1st to 12th fan sections of the indirect air-cooled tower. Figure 6 Schematic diagram of the windward inlet air angles of the 1st to 12th fan sections of an indirect air-cooled tower of a method for determining the most probable tower-side fan section of an indirect air-cooled tower provided by the present invention, as shown in Figure 6As shown in the figure, the wind coming from the due east direction is 0°, the wind coming from the due south direction is 90°, the wind coming from the due west direction is 180°, and the wind coming from the due north direction is 270°. The windward inlet angles of the 1st fan section are 30° to 60°, the windward inlet angles of the 2nd fan section are 0° to 30°, the windward inlet angles of the 3rd fan section are 330° to 360°, the windward inlet angles of the 4th fan section are 300° to 330°, the windward inlet angles of the 5th fan section are 270° to 300°, the windward inlet angles of the 6th fan section are 240° to 270°, the windward inlet angles of the 7th fan section are 210° to 240°, the windward inlet angles of the 8th fan section are 180° to 210°, the windward inlet angles of the 9th fan section are 150° to 180°, the windward inlet angles of the 10th fan section are 120° to 150°, the windward inlet angles of the 11th fan section are 90° to 120°, and the windward inlet angles of the 12th fan section are 60° to 90°.

[0081] Secondly, the inlet wind speed v and the inlet wind direction α are measured every 5 seconds by an integrated anemometer and wind vane, and the above data are statistically recorded in real time.

[0082] Next, it is judged whether the measured inlet wind direction values of the 1st to 12th fan sections of the indirect air-cooling tower satisfy 0° ≤ α ≤ 360°. If so, the actual inlet angles of the 1st to 12th fan sections are calculated; otherwise, the data is deleted and the result is output.

[0083] Subsequently, the difference between the inlet wind direction α of the 1st to nth fan sections of the indirect air-cooling tower and the average value of the windward inlet angles of each fan section is calculated as the inlet angle β. r , if the inlet angle β r ≤ 180°, the actual inlet angle β of each fan section is β r ; if the inlet angle β r > 180°, the actual inlet angle β of each fan section is 360° - β r ; the value range of the actual inlet angle β of the 1st to nth fan sections is 0° ≤ β ≤ 180°.

[0084] Table 1

[0085]

[0086] Referring to Table 1 that records the number of occurrences of the fan section with the minimum actual inlet angle, the measured inlet wind speed, the actual inlet angle, the cosine value of the actual inlet angle, and the radial average wind speed data for the 1st to 12th fan sections under the June working condition and Figure 7 the actual inlet angle values of the 1st to 12th fan sections of the indirect air-cooling tower shown under the June working condition, calculate the actual inlet angle values of the 1st to 12th fan sections of the indirect air-cooling tower under the June working condition and statistically record the data. By comparing the actual inlet angle values of the 1st to 12th fan sections under the June working condition, it can be seen that the fan sections with the minimum actual inlet angle values of the 1st to 12th fan sections under the June working condition are the 1st fan section, the 11th fan section, the 4th fan section, and the 5th fan section in sequence.

[0087] Refer to Table 1 and Figure 8 the number of occurrences of the fan section with the minimum actual inlet air angle among the 1st to 12th fan sections of the indirect air-cooling tower under the June operating condition shown. In the embodiments of the present invention, the number of occurrences of the fan section with the minimum actual inlet air angle among the 1st to 12th fan sections of the indirect air-cooling tower under the June operating condition is counted, and the data is recorded. By comparing the number of occurrences of the fan section with the minimum actual inlet air angle among the 1st to 12th fan sections under the June operating condition, it can be known that the fan sections with the most occurrences of the fan section with the minimum actual inlet air angle among the 1st to 12th fan sections under the June operating condition are the 1st fan section, the 5th fan section, the 11th fan section, and the 9th fan section in sequence.

[0088] Refer to Table 1 and Figure 9 the radial average wind speed values of the 1st to 12th fan sections of the indirect air-cooling tower under the June operating condition shown. In the embodiments of the present invention, the radial average wind speed of the 1st to 12th fan sections of the indirect air-cooling tower under the June operating condition is calculated, and the data is statistically recorded. By comparing the radial average wind speeds of the 1st to 12th fan sections under the June operating condition, it can be known that the fan sections with the maximum radial average wind speed v among the 1st to 12th fan sections under the June operating condition are the 1st fan section, the 4th fan section, the 11th fan section, and the 5th fan section in sequence.

[0089] Therefore, in this embodiment, among the 1st to 12th fan sections of the indirect air-cooling tower under the June operating condition, the fan section with the minimum average value of the actual inlet air angle is the 1st fan section, the fan section with the most occurrences of the fan section with the minimum actual inlet air angle is the 1st fan section, and the fan section with the maximum radial average wind speed is the 1st fan section. Therefore, it can be determined that the fan section on the most probable windward side of the indirect air-cooling tower under the June operating condition is the 1st fan section. This determination method is also applicable to the determination of the fan section on the most probable windward side under the annual operating condition.
