Description

Technical Field

[0001] This invention relates to the field of high voltage direct current (HVDC) transmission technology, and more specifically, to a method for arranging a square-ring simulated charge and matching points for a DC transmission line. Background Technology

[0002] Ultra-high voltage direct current (UHVDC) overhead transmission lines traverse thousands of kilometers, transferring energy from the base station to the load. Especially after the release of the Chinese national standard GB39220-2020, greater attention has been paid to the electrical environment of buildings near the lines. This standard, for the first time, sets limits on the electric field at balconies and platforms—places frequently used by humans. Before the standard's release, HHDC transmission line design specifications typically assumed the absence of buildings and required that the electric field at building locations not exceed 15 kV / m. Now, the impact of buildings on the combined electric field must be considered; the combined electric field at building balconies and platforms is becoming a decisive factor influencing line height, significantly impacting construction costs.

[0003] High-voltage direct current (HVDC) transmission lines span long distances and traverse buildings with complex and diverse geometries, making the prediction of the composite electric field on these buildings a challenging problem. The flux line method is an effective approach for calculating the composite electric field on buildings near HVDC transmission lines, but the simulated charge method is necessary to calculate the nominal electric field. For buildings with complex geometries, quickly and conveniently arranging simulated charges and matching points on them is extremely difficult. Summary of the Invention

[0006] The geometric model of the building adjacent to the DC transmission line is constructed using digital geometric modeling methods according to a predetermined scaling factor;

[0007] On the geometric model of the building, the surface that does not need to be arranged with square ring simulated charges is divided using the quadrilateral mesh subdivision method to obtain the first quadrilateral mesh.

[0008] Based on the building's geometric model, the geometric model of the arrangement surface for arranging the circular simulated charge needs to be reconstructed.

[0009] Based on the geometric model of the layout surface, the second quadrilateral mesh of the layout surface is obtained using the quadrilateral mesh subdivision method;

[0010] The arrangement of the simulated charges in the square ring is determined based on the set of elements formed by the horizontal sides of the first and second quadrilateral grids.

[0011] The position information of the center point of the line segment represented by each element after being restored according to the scaling factor is used as the arrangement matching point of the square ring simulated charge, where the arrangement matching point is used to calculate the magnitude of the corresponding square ring simulated charge.

[0012] Optionally, the operation of obtaining the second quadrilateral mesh of the arrangement surface based on the geometric model of the arrangement surface using a quadrilateral meshing method includes:

[0013] Perform a reverse stretching operation on the arrangement surface geometric model to create a rectangular platform;

[0017] The arrangement of the simulated charges in the square ring is determined based on the line segment represented by each element in the element set.

[0018] Optionally, it also includes:

[0019] Remove duplicate elements from the set of elements.

[0020] According to another aspect of the present invention, a square-ring simulated charge and matching point arrangement device for a DC transmission line is provided, comprising:

[0021] The first construction module is used to construct the building geometry model of the building adjacent to the DC transmission line according to a predetermined scale coefficient using digital geometric modeling methods;

[0022] The first meshing module is used to mesh the surfaces on the building geometry model that do not need to be arranged with square ring simulated charges using the quadrilateral meshing method, so as to obtain the first quadrilateral mesh.

[0023] The second construction module is used to reconstruct the geometric model of the arrangement surface for arranging the circular simulated charge based on the building's geometric model.

[0024] The second meshing module is used to obtain the second quadrilateral mesh of the layout surface based on the geometric model of the layout surface using the quadrilateral meshing method.

[0025] The determination module is used to determine the arrangement position of the square ring simulated charge based on the set of elements composed of the horizontal sides of the first quadrilateral grid and the second quadrilateral grid.

[0026] As a module, it is used to restore the position information of the center point of the line segment represented by each element according to the scaling factor as the arrangement matching point of the square ring simulated charge, wherein the arrangement matching point is used to calculate the magnitude of the corresponding square ring simulated charge.

[0027] According to another aspect of the present invention, a computer-readable storage medium is provided, the storage medium storing a computer program for performing the methods described in any of the above aspects of the present invention.

[0053] Exemplary methods

[0054] Figure 1This is a schematic flowchart illustrating a method for arranging a square-ring simulated charge and matching points in a DC transmission line, provided by an exemplary embodiment of the present invention. This embodiment can be applied to electronic devices, such as... Figure 1 As shown, the method 100 for arranging the square ring simulated charge and matching points of a DC transmission line includes the following steps:

[0055] Step 101: Construct the building geometry model of the building adjacent to the DC transmission line using digital geometric modeling methods according to a predetermined scale factor;

[0056] Step 102: On the geometric model of the building, the surface that does not need to be arranged with square ring simulated charges is divided using the quadrilateral mesh subdivision method to obtain the first quadrilateral mesh.

[0057] Step 103: Based on the building's geometric model, reconstruct the geometric model of the arrangement surface for arranging the circular simulated charges.

[0058] Step 104: Based on the geometric model of the layout surface, the second quadrilateral mesh of the layout surface is obtained using the quadrilateral mesh subdivision method;

[0059] Step 105: Determine the arrangement position of the square ring simulated charge based on the set of elements formed by the horizontal sides of the first quadrilateral grid and the second quadrilateral grid.

[0060] Step 106: The position information of the center point of the line segment represented by each element after being restored according to the scaling factor is used as the arrangement matching point of the square ring simulated charge, wherein the arrangement matching point is used to calculate the magnitude of the corresponding square ring simulated charge.

[0061] Optionally, the operation of obtaining the second quadrilateral mesh of the arrangement surface based on the geometric model of the arrangement surface using a quadrilateral meshing method includes:

[0062] Perform a reverse stretching operation on the arrangement surface geometric model to create a rectangular platform;

[0063] The side surface of the rectangular platform is divided using a quadrilateral meshing method to obtain a second quadrilateral mesh.

[0064] Optionally, the operation of determining the arrangement position of the square ring-shaped simulated charge based on the set of elements composed of the horizontal sides of the first quadrilateral grid and the second quadrilateral grid includes:

[0065] Take the horizontal edges of the first quadrilateral grid and the second quadrilateral grid to form the element set;

[0066] The arrangement of the simulated charges in the square ring is determined based on the line segment represented by each element in the element set.

[0067] Optionally, it also includes:

[0068] Remove duplicate elements from the set of elements.

[0069] Specifically, in solving the electric field, discrete charges (simulated charges) are arranged outside the boundary of the computational domain to replace these unknown continuously distributed charges. Matching points should also be arranged on the boundary, and their number is generally consistent with the number of simulated charge points. Then, based on the premise that the boundary conditions remain unchanged before and after the equivalent substitution, the magnitude of each simulated charge can be obtained. Once the magnitude of the discrete charges can be solved, the field quantity (φ, E) at any point in the field domain can be obtained through superposition calculation. The solution obtained in this way is the approximate solution of the original field. The above is the basic idea of ​​the simulated charge method. This invention proposes a method for arranging square and ring simulated charges and matching points in DC transmission lines. The specific steps are as follows:

[0070] Step 1: Create a geometric model of the building using digital geometric modeling methods, and scale it down according to a preset ratio, such as... Figure 2 As shown. The preset ratio coefficient can be set by the user and is not limited here.

[0071] Step 2: On the geometric model of the building, use the quadrilateral meshing method to mesh the surfaces that do not require the placement of square ring-shaped simulated charges, obtaining the first quadrilateral mesh, such as... Figure 3 As shown.

[0072] Step 3: For the surfaces where simulated charges need to be arranged, first recreate the geometric model of these surfaces, and then create rectangular truncated platforms on these surfaces through a reverse stretching operation, such as... Figure 4 As shown.

[0073] Step 4: Use the quadrilateral meshing method to mesh the sides of the rectangular frustum to obtain a second quadrilateral mesh, such as... Figure 5 As shown.

[0074] Step 5: Take the horizontal edges of the first and second quadrilateral grid cells to form an element set. Remove duplicate elements from the element set. Each element in this set serves as a line segment to simulate the position of a charge, such as... Figure 6a , Figure 6b as well as Figure 6c As shown.

[0075] Step 6: Based on the set obtained in Step 5, take the midpoint of each element in the set, and enlarge the positions of these points according to the reciprocal of the scaling factor in Step 1 to obtain the matching points, such as... Figure 7a , Figure 7b as well as Figure 7c As shown.

[0076] Therefore, this application provides a method for arranging simulated charges and matching points for DC transmission lines. By constructing a geometric model of a building adjacent to the DC transmission line, a first quadrilateral mesh is constructed for the surface where simulated charges do not need to be arranged, and a second quadrilateral mesh is constructed for the surface where simulated charges are arranged. Then, the locations of the simulated charges and the matching points are extracted, solving the problem of arranging simulated charges on buildings with complex geometric structures. This solves the problem of calculating the nominal electric field on buildings with complex geometric structures near high-voltage DC transmission lines using the simulated charge method, laying the foundation for the calculation of the synthetic electric field.
