Description

Technical Field

[0001] This invention relates to the field of digital design technology for transmission lines, and more specifically, to a method, system, device, and medium for calculating the coordinates of equal-length tower legs of portal towers for power grid digitalization. Background Technology

[0002] With the continuous expansion of new energy sources and power grid scale, the construction environment for transmission lines is becoming increasingly complex, often requiring passage through steep mountainous areas, heavy icing zones, and other harsh terrains. Under the background of ultra-high voltage transmission technology application and the use of large-section conductors, conductor loads have increased significantly, and traditional single-circuit or double-circuit conventional tower structures are no longer fully capable of meeting the requirements of high loads and special terrains. Therefore, twin-tower portal towers, due to their excellent load-bearing performance and adaptability to complex terrain, have become an important solution in transmission line design.

[0003] However, portal towers consist of two sub-towers, making the calculation of their leg coordinates far more complex than that of conventional towers. The arrangement of portal towers involves not only the path angles of the railway line but also the lateral offset of the sub-towers relative to the line center, the rotation of the sub-towers themselves, and the coupling of geometric parameters such as the leg root opening. In current engineering design practice, determining the leg coordinates of portal towers primarily relies on designers drawing each tower individually in CAD software, and then manually or through simple plugins to extract the coordinate data. This traditional approach has the following significant problems: Inefficient: For long-distance transmission lines, drawing portal towers one by one and extracting data is time-consuming and labor-intensive, which seriously affects the design schedule; Poor accuracy: The manual drawing and extraction process is easily affected by human factors, and the accuracy of coordinate data is difficult to strictly control; Verification difficulties: Due to the lack of a unified and refined mathematical calculation model, subsequent disciplines such as water conservation and forestry surveys find it difficult to quickly and in batches verify the accuracy of this data.

[0004] The aforementioned problems not only increase the cost and risk of engineering design, but also severely restrict the transformation needs of power grid digitalization and high-quality construction. Therefore, there is an urgent need for a method and system for calculating the coordinates of portal tower legs based on a rigorous mathematical model, capable of automation and high-precision calculation.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The following reference Figures 1 to 4 This invention describes a method, system, device, and medium for calculating the coordinates of equal-length portal tower legs for power grid digitalization, provided by some embodiments of the present invention.

[0040] Some embodiments of this application provide a method for calculating the coordinates of equal-length tower legs of portal towers for power grid digitalization.

[0041] like Figure 1 As shown, the first embodiment of the present invention proposes a method for calculating the coordinates of equal-length tower legs of portal towers for power grid digitalization, including the following steps S1 to S4.

[0042] S1. Obtain the tower location path parameters and portal tower design parameters of the transmission line; the tower location path parameters include the tower location center coordinates, tower location number and path turning angle, etc., and the portal tower design parameters include the sub-tower spacing and the sub-tower leg root opening, etc.

[0043] like Figure 2 As shown, the portal tower consists of two sub-towers, M1 (left sub-tower) and M2 (right sub-tower), with a center-to-center distance between them. The above parameters can be obtained through line design schemes or actual operation.

[0044] S2. Using the preset coordinate axis as a reference, the tower position is normalized according to the center coordinates of the tower position and the path turning angle, and the normalized turning angle of the tower position is calculated.

[0045] Figure 3The diagram shows a top plan view of the footprint of a portal tower leg. As those skilled in the art will know, a transmission line route consists of multiple consecutive tower locations and paths, forming a tower-line system. In the diagram, N01 and N02 represent the tower location numbers of two adjacent portal towers. The path angles for the tower locations are generally considered positive (clockwise), with right turns being positive and left turns being negative. M1 and M2 are illustrated using the center stakes of the left and right sub-towers of a single portal tower location, respectively. A1, B1, C1, and D1 represent the positions of the tower legs of the left sub-tower M1; A2, B2, C2, and D2 represent the positions of the tower legs of the right sub-tower M2. It is the included angle between the diagonal half-legs of each leg, which is usually a fixed value, taken as 90°. Figure 3 In the illustrated embodiment, the X-axis and Y-axis directions are defined. It can be understood that the X-axis direction and the Y-axis direction are two mutually perpendicular directions in the same plane, and can be flexibly set as needed.

[0046] Given the coordinates of the tower center and the path turning angles, before solving for the coordinates of each sub-tower of the portal tower, it is necessary to perform normalization processing on the path turning angles and the direction of travel.

[0047] In one specific embodiment, the method for calculating the normalized rotation angle of the tower location includes: Selecting the X-axis as the preset coordinate axis, and using the X-axis as the reference, the normalized rotation angle of the two tower positions is calculated based on the center coordinates and path rotation angles of the two adjacent portal tower positions:

[0049] Among them, N01 and N02 represent the tower position numbers of two adjacent portal towers; The center coordinates of the portal tower N01; The center coordinates of the portal tower N02; The path turning angle for portal tower N01; The path turning point for portal tower N21; This represents the normalized rotation angle of tower position N01 towards the X-axis. Represents the arctangent function; The sign for determining the direction of the path turning corner is + or - depending on the direction of the path turning corner. This represents the normalized rotation angle of tower position N02 towards the X-axis.

[0050] Specifically, the direction of the path turning angle is determined according to the principle of clockwise as positive. That is, when turning right compared to the previous level portal tower, the sign of the path turning angle is positive; when turning left compared to the previous level portal tower, the sign of the path turning angle is negative.

[0051] S3. Based on the center coordinates of the tower location, the spacing between the sub-towers, and the normalized rotation angle, calculate the center coordinates of the left sub-tower and the center coordinates of the right sub-tower of the portal tower.

[0055]

[0056] in, The coordinates of the center of the left sub-tower M1 of portal tower N01 are given. is the center coordinate of the right sub-tower M2 of portal tower N01; S represents the distance between the two sub-towers in portal tower N01.

[0057] This embodiment illustrates the method for calculating the center coordinates of the left and right sub-towers of the N01 portal tower. Similarly, the center coordinates of the left and right sub-towers of the N02 portal tower can be calculated as follows:

[0058]

[0059]

[0060]

[0061] in, The coordinates of the center of the left sub-tower M1 of portal tower N02 are given. The coordinates are the center coordinates of the right sub-tower M2 of portal tower N02.

[0062] S4. Based on the center coordinates of the left sub-tower, the center coordinates of the right sub-tower, the root opening of the tower leg, and the normalized rotation angle, the corner coordinates of each tower leg of the left and right sub-towers are calculated using a preset geometric solution model.

[0063] Understandably, for portal-type towers with equal-length legs, the root opening of each leg is a fixed value. Taking tower N01 as an example, its leg root opening is... .

[0064] The calculation method for the corner coordinates of each leg of the left and right sub-towers of tower site N01 includes: ,

[0065] ,

[0066] ,

[0067] ,

[0068] Among them, A1, B1, C1, and D1 are the tower leg numbers of the left sub-tower M1; Indicates the coordinates of leg A1 of the left sub-tower M1; Indicates the coordinates of leg B1 of the left sub-tower M1; Indicates the coordinates of leg C1 of the left sub-tower M1; Indicates the coordinates of leg D1 of the left sub-tower M1; This indicates that the base of the tower leg of portal tower N01 is open; ,

[0069] ,

[0073] Similarly, the corner coordinates of each leg of the left and right sub-towers of tower position N01 can be solved by referring to the above formula. Simply replace them with the corresponding sub-tower center coordinates, the base opening of the tower leg, and the normalized rotation angle.

[0074] In some implementations, the method also includes: The calculated corner coordinates of each tower leg are output to the visualization interface, and CAD software is called to draw point and line graphics based on the corner coordinates to generate a plan view of the footprint of the portal tower legs. The corner coordinates and plan data are then converted into a PDF or CAD format file containing the coordinate vectors of the tower legs' footprint, and output to the terminal for online review.

[0075] Other embodiments of the present invention provide a coordinate calculation system for equal-length tower legs of portal towers for power grid digitalization, used to implement the method described in any of the above embodiments.

The path information database stores the tower location path parameters, including the route design path angle, tower location coordinates, and tower location number; the design information database stores the portal tower design parameters, including the portal tower sub-tower spacing and the portal tower sub-tower leg root opening. The data acquisition module is connected to the path information database and the design information database respectively to read the data stream.

[0079] In one specific embodiment, the data stored in the path information database and the design information database can be imported in .xls or .xlsx format.

It can also call CAD software to draw point and line graphics of the coordinates, realize the visualization display of the land area coordinates, and call up digital modules such as water supply and conservation and forest survey.
