Description

Technical Field

[0001] This invention relates to the field of power engineering simulation, and in particular to a method, apparatus, equipment and storage medium for arranging spacers in transmission lines. Background Technology

[0002] Within the transmission line operation system, spacers are key hardware components ensuring the safe operation of split conductors. They fix the spacing between multiple sub-conductors, reducing conductor vibration and galloping. Common configurations include two-, four-, and six-split structures, and their position and orientation must match the spatial morphology of the conductors. With the development of power grid digitalization, spacers are widely distributed along conductors, resulting in a heavy modeling workload. Conductors exhibit sag and spatial curvature, and various vector data sources contain errors, necessitating automated and high-precision methods for batch placement modeling of spacers.

[0003] Currently, when building 3D scenes of transmission lines in the industry, spacer placement mainly employs two methods: manual placement and semi-automatic placement using fixed templates. Both methods require the prior input of basic data such as conductor and ground wire vectors, spacer installation distances, and standard hardware models. Manual placement relies on modelers placing the model segment by segment, manually adjusting its position, rotation angle, and dimensions. Fixed templates pre-lock the relative positions of the internal components of the spacers, placing the entire model based on a single reference datum. During operation, it is simple to distinguish the line split type and select the corresponding template. After the basic placement is completed, manual fine-tuning is performed, ultimately generating a 3D model of the spacers for use in building the line scene.

[0004] Manual operation is extremely labor-intensive for long-distance, multi-span lines, making batch modeling impossible. Fixed templates have a fixed posture and cannot adaptively adjust their orientation to follow the 3D curve of the conductor, resulting in poor model fit. Furthermore, they are susceptible to uneven conductor spacing and vector data errors, leading to gaps and distortions in fixed-size fittings. They also struggle to accommodate various split conductor types, making it impossible to batch calculate and instantiate complete spacer bar models, thus limiting their practical engineering applicability. Summary of the Invention

[0005] This invention provides a method, apparatus, equipment, and storage medium for placing spacers in transmission lines, which solves the technical problems of low efficiency in manual placement of spacers in 3D modeling of transmission lines, inability to adapt the posture to conductor curves, distortion of fitting between fittings and intermediate rings, and difficulty in compatibility with various split conductor structures.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] Example 1 Figure 1 This is a flowchart illustrating a method for placing spacers in a transmission line according to Embodiment 1 of the present invention. This embodiment is applicable to transmission line simulation design scenarios. The method can be executed by a spacer placement device, which can be implemented in hardware and / or software and can be configured in a computer controller. Figure 1 As shown, the method includes: S110. Obtain the basic data of the transmission line, including conductor and ground wire vector lines, spacer arrangement arc length distance, and spacer model library parameters.

[0023] The basic data refers to the set of input data used to support the automatic placement of spacers, including conductor / ground wire vector lines, spacer arrangement arc length distances, and spacer model library parameters. Conductor / ground wire vector lines are curve data composed of continuous three-dimensional coordinate points, describing the direction of the conductor or ground wire in three-dimensional space. For non-split ground wires, a single ground wire vector line needs to be input, while for split conductors, the vector line of each split sub-conductor needs to be input. Spacer arrangement arc length distance refers to the arc length distance between the spacer and the starting point of the conductor / ground wire; a single value or a set of values ​​can be input for batch positioning of spacers along the conductor. Spacer model library parameters can include preset parameters for the intermediate ring model and connecting conductor hardware model, such as the original model length and local coordinate system definition. Spacers are auxiliary hardware used to maintain the relative spacing of split sub-conductors, consisting of an intermediate ring and connecting conductor hardware. The intermediate ring is the central connecting structure of the spacer, located near the geometric center of the split conductor. Connecting conductor hardware is the component that connects the intermediate ring to each split sub-conductor.

[0024] Optionally, before determining the splitting of the transmission line, the method further includes: calculating the spatial length of each segment formed by adjacent sampling points in the conductor-ground vector line; accumulating the arc lengths based on each spatial length to obtain an arc length index sequence; matching the target segment in the arc length index sequence with the arc length distance corresponding to the spacer bar arrangement; performing linear interpolation based on the target segment to obtain the spatial sampling point corresponding to the arc length distance of the spacer bar arrangement; determining the direction vector of the target segment, and normalizing the direction vector to obtain the unit tangential vector of unit modulus.

[0025] In this context, a line segment formed by adjacent sampling points refers to a spatial line segment formed by connecting two consecutive sampling points on a vector line. The spatial length of a line segment is the Euclidean distance between a single adjacent sampling point line segment in three-dimensional space. The arc length index sequence is an ordered sequence formed by accumulating the spatial lengths of each line segment from the starting point of the vector line, with each sampling point corresponding to a cumulative arc length value. The spacer bar arrangement arc length distance is a curve length parameter measured along the traverse curve from the starting point of the vector line, used to locate the spacer bar installation position. The target line segment is the adjacent sampling point line segment in the arc length index sequence whose cumulative arc length exactly encloses the arrangement arc length distance. Linear interpolation is a geometric interpolation method that calculates the intermediate spatial point position between the two endpoints of the target line segment in three-dimensional coordinates according to the proportion of the arrangement arc length distance to the total length of the line segment.

[0026] Specifically, first, traverse all continuous three-dimensional sampling points along the entire conductor vector line, and then take each group of adjacent sampling points one after the other. Calculate the spatial length of the line segment connecting each group of adjacent sampling points using the three-dimensional Euclidean distance formula. Record the length of each line segment on the vector line completely. The spatial length is calculated using the following formula (1): (1) in, This represents the spatial length of the k-th adjacent sampling point segment on the vector line. This represents the k-th three-dimensional sampling point on the conductor-ground vector line. , , and These represent the X, Y, and Z spatial coordinates of the point in the three-dimensional geodetic coordinate system, respectively, and k is the sampling point number, with values ​​of 0, 1, 2...n. This represents the (k+1)th three-dimensional sampling point on the conductor vector line. Then, taking the first sampling point of the vector line as the starting point for arc length calculation, the cumulative arc length value corresponding to the starting point is set to 0. Following the arrangement order of the vector line segments, the cumulative arc length of the previous segment is added to the spatial length of the current segment to complete the arc length accumulation operation. The cumulative arc length value corresponding to each sampling point is obtained in turn. All sampling points and their corresponding cumulative arc lengths are stored one-to-one to form a complete and ordered arc length index sequence. This sequence can establish a one-to-one mapping relationship between each spatial point on the vector line and the cumulative length along the conductor curve. The cumulative arc length is expressed by the following formula (2): (2) in, This represents the cumulative arc length corresponding to the k-th three-dimensional sampling point on the conductor-ground vector line. Let represent the three-dimensional Euclidean length of the j-th adjacent sampling point segment on the conductor vector line. Then, traverse all the cumulative arc length values ​​stored in the arc length index sequence, and find a set of adjacent sampling points that satisfy the condition that the cumulative arc length of the previous sampling point is less than or equal to the arrangement arc length distance and the cumulative arc length of the next sampling point is greater than or equal to the arrangement arc length distance, as shown in the following formula (3): (3) in, This represents the cumulative arc length corresponding to the k-th three-dimensional sampling point on the conductor-ground vector line. Indicates the arc length distance of the spacer bar arrangement. This represents the cumulative arc length corresponding to the (k+1)th three-dimensional sampling point on the conductor vector line. The line segment connecting the sampling points is the target line segment. Then, the three-dimensional coordinates of the two endpoints of the target line segment, the total spatial length of the target line segment, and the difference between the arc length distance and the cumulative arc length of the front end point of the target line segment are read. The difference is divided by the total length of the target line segment to obtain the interpolation ratio coefficient. Then, the three-dimensional coordinates of the starting point and ending point of the target line segment are linearly weighted using this ratio coefficient. After weighted summation, the conductor spatial sampling point that accurately corresponds to the arc length distance of the spacer is obtained. This point is the reference positioning point of the spacer on the conductor. The interpolation ratio coefficient is shown in the following formula (4): (4) in, Indicates the interpolation scaling factor. This represents the cumulative arc length corresponding to the k-th three-dimensional sampling point on the conductor-ground vector line. Indicates the arc length distance of the spacer bar arrangement. This represents the cumulative arc length corresponding to the (k+1)th three-dimensional sampling point on the conductor vector line. The spatial sampling points are calculated using the following formula (5): (5) in, Indicates spatial sampling points, Indicates the interpolation scaling factor. This represents the k-th three-dimensional sampling point on the conductor-ground vector line. This represents the (k+1)th three-dimensional sampling point on the conductor vector line. Then, the three-dimensional coordinates of the front end point are subtracted from the three-dimensional coordinates of the rear end point of the target line segment to obtain the original three-dimensional direction vector representing the local orientation of the conductor. The overall magnitude of this direction vector is then calculated. The x, y, and z coordinate components of the direction vector are divided by the magnitude to complete the normalization process, and finally, a unit tangential vector with a fixed magnitude of 1 is obtained, which only represents the local extension orientation of the conductor. The direction vector is calculated using the following formula (6): (6) in, This represents the original, unnormalized direction vector of the conductor at the arc length dis, indicating the local extension direction of the conductor. This represents the k-th three-dimensional sampling point on the conductor-ground vector line. This represents the (k+1)th three-dimensional sampling point on the conductor vector line. The unit tangential vector will be used later to solve the spatial attitude rotation matrix of the spacer intermediate ring and connecting conductor hardware. The entire set of pre-calculations relies on the geometric principle of vector discrete point arc length interpolation, which can adapt to the three-dimensional curve shape of the conductor with sag, height difference, and spatial curvature, ensuring that the calculation results of the spacer positioning point and the local direction of the conductor closely match the actual spatial shape of the line.

[0027] S120. Determine the splitting status of the transmission line and calculate the spacer placement parameters based on the splitting status and basic data.

[0028] The term "split configuration" refers to the type of split structure of the conductors in the transmission line, such as two-split, four-split, or six-split, or whether it is a non-split ground wire. The split configuration determines the number and layout of the intermediate rings and connecting hardware of the spacers. Spacer placement parameters are key parameters calculated to control the placement of the spacer model, and can include position parameters, orientation parameters, and scaling parameters. Position parameters can be the spatial position of the intermediate rings and the spatial positions of each connecting hardware. Orientation parameters can be the spatial orientation of the intermediate rings and connecting hardware. Scaling parameters can be the adaptive scaling ratio of the connecting hardware.

[0029] S130. Instantiate the spacer placement parameters to generate the spacer placement result.

[0030] Instantiation refers to the process of applying the calculated placement parameters to model components in the spacer model library, such as intermediate rings and connecting fittings, to generate spacer model instances that can be directly displayed or used in a 3D scene. The final output of the spacer placement result clock is a 3D arrangement of spacers, including the position coordinates, rotation Euler angles, scaling ratios, and other data of the intermediate rings and each connecting fitting. This data can be directly used for model display and application in scenarios such as 3D Geographic Information System (GIS) and digital twin power grids for power transmission lines.

[0031] The technical solution of this invention determines the splitting condition of the transmission line and calculates the spacer placement parameters based on basic data. It can distinguish different split conductor structures and match the corresponding calculation logic, independently solve the position, orientation, and scaling parameters of the intermediate ring and connecting hardware, and realize the adaptive adaptation of each component of the spacer to the real spatial shape of the conductor, eliminating the problems of manual adjustment error and model fitting distortion. The spacer placement parameters are instantiated to generate spacer placement results, and standardized spacer 3D model instances can be automatically generated in batches based on the parameters obtained from batch calculation, saving manual adjustment operation for each component and improving the modeling efficiency of 3D scenes of long-distance transmission lines.

[0032] Example 2 Figure 2 This is a flowchart of a method for placing spacers in a transmission line according to Embodiment 2 of the present invention. This embodiment elaborates on the calculation process of spacer placement parameters for split conductors based on Embodiment 1 described above. For example... Figure 2 As shown, the method includes: S210. When the splitting situation is a split conductor, calculate the positioning reference of the intermediate loop of each split sub-conductor.

[0033] The intermediate loop positioning reference is a geometric calculation reference applicable only to the split conductor condition and used to solve for the center point of the intermediate loop. A split sub-conductor refers to a single cable within the same phase that is parallel to each other and together constitutes the split conductor.

[0034] Optionally, the intermediate loop positioning reference for each split sub-traverse is calculated, including: taking the arithmetic mean of each spatial sampling point to obtain the geometric center point of each split sub-traverse, and using the center line formed by the geometric center points as the intermediate loop positioning reference.

[0035] The geometric center point is the arithmetic mean of spatial points at the same arc length position of multiple split sub-conductors. The centerline is a curve formed by the geometric center points at each arc length position.

[0036] Specifically, when calculating the positioning reference of the intermediate ring of each split sub-conductor, the corresponding spatial sampling point is first found on each sub-conductor by using the arc length parameterization method, that is, the spatial position of each split sub-conductor at a distance dis from the starting point. Then, the spatial sampling points of all split sub-conductors located at the same arc length position are calculated by arithmetic mean, and the result is the geometric center point of the split conductor at that arc length position. For cases where multiple spacers need to be arranged, the geometric center point corresponding to each distance parameter dis is calculated in sequence according to the above method. The curve formed by connecting the geometric center points in space is the center line of the split conductor. This center line can be used as the reference for positioning the intermediate ring of the spacer. The geometric center point is calculated using the following formula (7): (7) in, This represents the geometric center point of all sampling points of the split sub-traverses at the same arc length dis. Indicates the number of splitting wires. This represents the spatial sampling point corresponding to the i-th split sub-wire at the same arc length dis.

[0037] S220. Calculate the geometric center point of each split sub-conductor by using the spatial sampling points corresponding to the arc length distance of the spacer bar and use them as the position of the intermediate ring. Use the spatial sampling points corresponding to each split sub-conductor as the positions of the corresponding hardware.

[0038] Specifically, the coordinates of the spatial sampling points at the arc length distance dis of all the split sub-wires can be averaged to obtain the position of the intermediate ring in three-dimensional space. Simultaneously, the spatial sampling points corresponding to each split sub-wire at dis are directly used as the positions of the fittings connected to that split sub-wire. The position of the intermediate ring is calculated using the following formula (8): (8) in, Indicates the position of the middle ring. The geometric center point of all sampling points of the split sub-conductors at the same arc length dis is represented by the following formula (9): (9) in, Indicates the position of the hardware, This represents the spatial sampling point corresponding to the i-th split sub-wire at the same arc length dis.

[0039] In an optional implementation, after acquiring the spatial points of all split sub-traverses at the same arc length location, a three-dimensional minimum bounding box can be constructed, with the geometric center of the bounding box serving as the placement position of the intermediate ring of the spacer bar. The above implementation is suitable for conditions involving local traverse offset, asymmetrical splitting, and slight acquisition errors in the measured vector points, and can mitigate the offset interference caused by abnormal points on a single sub-traverse on the position of the intermediate ring.

[0040] S230. Use the unit tangential vector corresponding to the positioning reference of the intermediate ring as the horizontal axis of the intermediate ring.

[0041] The horizontal axis of the intermediate ring is the axis along the direction of the conductor in the local coordinate system of the intermediate ring, and it is aligned with the unit tangential vector.

[0042] S240. Obtain the vertical reference vector, perform a cross product between the horizontal axis of the middle ring and the vertical reference vector to obtain the vertical axis of the middle ring, and perform a cross product between the horizontal axis of the middle ring and the vertical axis of the middle ring to obtain the vertical axis of the middle ring.

[0043] Wherein, the vertical reference vector is a unit vector pointing in the vertical direction, such as (0,0,1) representing vertically upward. The vertical axis of the intermediate ring is the horizontal axis perpendicular to the horizontal axis in the local coordinate system of the intermediate ring. The vertical axis of the intermediate ring is the vertical axis perpendicular to both the horizontal and vertical axes in the local coordinate system of the intermediate ring. The vertical axis of the intermediate ring is calculated using the following formula (10): (10) in, Indicates the horizontal axis of the middle ring. Indicates the vertical axis of the middle ring. This represents the vertical reference vector.

[0044] S250. The rotation matrix of the intermediate ring is obtained by splicing the horizontal axis, vertical axis and vertical axis of the intermediate ring. The rotation matrix of the intermediate ring is converted into Euler angles to obtain the rotation parameters of the intermediate ring.

[0045] The intermediate ring rotation matrix is ​​a 3x3 orthogonal matrix used to describe rotations in three-dimensional space. It is composed of three mutually perpendicular unit vectors: the horizontal axis, the vertical axis, and the center axis. Euler angles are three rotation angles: rotations about the x-axis, y-axis, and z-axis, used to describe rotations in three-dimensional space.

[0046] Specifically, the three-dimensional vectors of the three axes can be concatenated as column vectors to form the intermediate ring rotation matrix. Then, the matrix can be solved by converting the rotation matrix to Euler angles, and the rotation angle values ​​around the three axes can be output. This set of angle values ​​is the intermediate ring rotation parameter.

[0047] S260. Use the unit tangential vector as the horizontal axis of the fitting, and determine the radial vector pointing from the position of the fitting to the position of the intermediate ring.

[0048] In this system, the horizontal axis of the fitting is the axis along the direction of the conductor in the local coordinate system of the connecting wire fitting. The radial vector is the vector from the position of the fitting to the position of the intermediate loop.

[0049] S270. Based on the cross product of the horizontal axis and radial vector of the fitting, the vertical axis and the vertical axis of the fitting are obtained.

[0050] Wherein, the vertical axis of the fitting is the axis perpendicular to the horizontal axis in the local coordinate system of the fitting. The vertical axis of the fitting is the axis perpendicular to both the horizontal and vertical axes in the local coordinate system of the fitting. The vertical axis of the fitting is calculated using the following formula (11): (11) in, Indicates the longitudinal axis of the hardware. Indicates the horizontal axis of the hardware. Represents the radial vector. The vertical shaft of the fitting is calculated using the following formula (12): (12) in, Indicates the horizontal axis of the hardware. Indicates the longitudinal axis of the hardware. This indicates the vertical axis of the fitting. Furthermore, to ensure that the three directional axes are strictly orthogonal, the longitudinal axis of the fitting is further modified using the following formula (13): (13) in, Indicates the horizontal axis of the hardware. Indicates the longitudinal axis of the hardware. This indicates a metal fitting vertical shaft.

[0051] S280. The rotation matrix of the fitting is obtained by splicing the horizontal axis, vertical axis and vertical axis of the fitting. The rotation matrix of the fitting is converted into Euler angles to obtain the rotation parameters of the fitting.

[0052] Specifically, the rotation parameters are converted into three-axis Euler angles through matrix calculation and used as the rotation parameters specific to this branch fitting. This calculation logic is repeated for each branch fitting corresponding to a split sub-wire to obtain all fitting rotation parameters.

[0053] S290. Calculate the scaling parameters based on the hardware position, intermediate ring position, and spacer bar model library parameters.

[0054] The scaling parameter is a scaling factor calculated based on the actual length that the connecting hardware needs to cover and the original length of the model. It is used to adjust the length of the connecting hardware to fit the middle ring.

[0055] Optionally, scaling parameters are calculated based on the hardware position, intermediate ring position, and spacer model library parameters, including: calculating the spatial distance from the hardware position to the intermediate ring position; extracting the intermediate ring radius and original connection length from the spacer model library parameters, calculating the difference between the spatial distance and the intermediate ring radius to obtain the target connection length; and calculating the ratio of the target connection length to the original connection length to obtain the scaling parameters.

[0056] Specifically, the spatial distance from the fitting location to the intermediate ring location is first calculated. It's known that the connecting fitting only needs to cover the distance from the fitting installation point to the outer edge of the intermediate ring, without including the radius of the intermediate ring. Therefore, the pre-stored intermediate ring radius and the original connection length of the connecting fitting need to be extracted from the spacer model library parameters. The target connection length is obtained by subtracting the intermediate ring radius from the spatial distance. Then, the ratio of the target connection length to the original connection length is calculated to obtain the scaling parameter. This ratio reflects the difference between the actual connection length and the initial model length. Using this as a scaling factor, the connecting fitting model is scaled proportionally, ensuring that the length of the fitting model perfectly matches the actual installation requirements. This avoids gaps between the fitting and the intermediate ring, or the fitting being too long and interfering with the intermediate ring, ensuring the installation accuracy of the spacer and the accuracy of the model display.

[0057] The technical solution of this invention calculates the positioning reference for the intermediate ring separately for split conductors. The geometric center point is obtained by taking the arithmetic mean of sampling points of the same arc length for each sub-conductor and connecting them to form a centerline as the positioning reference. This accurately fits the overall spatial distribution of the split conductors, ensuring the intermediate ring is located in the central region of the sub-conductors. By constructing an orthogonal triaxial axis of the intermediate ring with the centerline tangent and converting it to Euler angles, the rotation parameters of the intermediate ring are automatically generated according to the conductor direction. The rotation parameters of the fitting are obtained by constructing the triaxial axis of the fitting by combining the cross product of the sub-conductor tangent and radial vectors, ensuring the natural and reasonable orientation of both types of components. By calculating the scaling ratio, the length of the fitting can be adaptively adjusted, effectively avoiding modeling defects such as gaps, intersections, and suspensions between the fitting and the intermediate ring.

[0058] Example 3 Figure 3 This is a flowchart of a method for placing spacers in a transmission line according to Embodiment 2 of the present invention. This embodiment elaborates on the calculation process of spacer placement parameters for non-split conductors, based on Embodiment 1 described above. For example... Figure 3 As shown, the method includes: S310. When the splitting condition is a non-split conductor, the spatial sampling point of the conductor-ground vector line at the arc length distance of the spacer bar is directly used as the position of the intermediate loop.

[0059] Specifically, when the splitting situation is a non-split conductor, the position of the intermediate loop is first calculated. The conductor vector line can be parameterized by arc length. The line segment corresponding to the arc length distance dis of the spacer bar arrangement can be found by accumulating the arc length sequence. After calculating the interpolation ratio, the spatial sampling point at the arc length distance is obtained, as shown in the following formula (14): (14) in, Indicates the position of the middle ring. This represents the spatial sampling point of the conductor vector line corresponding to the arc length distance of the spacer bar arrangement.

[0060] S320, Use the unit tangential vector as the horizontal axis of the intermediate loop.

[0061] Specifically, when determining the horizontal axis of the intermediate ring, the unit tangential vector of the ground line vector at position dis can be used as the horizontal axis of the intermediate ring.

[0062] S330. Obtain the vertical reference vector, perform a cross product between the horizontal axis of the middle ring and the vertical reference vector to obtain the vertical axis of the middle ring, and perform a cross product between the horizontal axis of the middle ring and the vertical axis of the middle ring to obtain the vertical axis of the middle ring.

[0063] The vertical reference vector is a unit vector pointing vertically, such as (0,0,1) representing vertically upward. The vertical axis of the intermediate ring is the horizontal axis perpendicular to the horizontal axis in the local coordinate system of the intermediate ring. The vertical axis of the intermediate ring is the vertical axis perpendicular to both the horizontal and vertical axes in the local coordinate system of the intermediate ring.

[0064] S340. The rotation matrix of the intermediate ring is obtained by splicing the horizontal axis, vertical axis and vertical axis of the intermediate ring. The rotation matrix of the intermediate ring is converted into Euler angles to obtain the rotation parameters of the intermediate ring.

[0065] The intermediate ring rotation matrix is ​​a 3x3 orthogonal matrix used to describe rotations in three-dimensional space. It is composed of three mutually perpendicular unit vectors: the horizontal axis, the vertical axis, and the center axis. Euler angles are three rotation angles: rotations about the x-axis, y-axis, and z-axis, used to describe rotations in three-dimensional space.

[0066] Specifically, the three-dimensional vectors of the three axes can be concatenated as column vectors to form the intermediate ring rotation matrix. Then, the matrix can be solved by converting the rotation matrix to Euler angles, and the rotation angle values ​​around the three axes can be output. This set of angle values ​​is the intermediate ring rotation parameter.

[0067] The technical solution of this invention, for non-split conductors, directly takes the spatial sampling point corresponding to the arc length of the conductor-ground vector line as the position of the intermediate loop, which can eliminate the centerline calculation calculation, simplify the position calculation logic in non-split cable scenarios, and reduce computing power consumption. By using the unit tangential vector as the horizontal axis of the intermediate loop, it can accurately fit the local direction of the conductor, ensuring that the intermediate loop is aligned along the extension direction of the cable. By generating the vertical axis and the vertical reference vector of the intermediate loop by cross product of the horizontal axis and the vertical reference vector, a pairwise orthogonal three-axis coordinate system can be quickly constructed, ensuring that the attitude reference conforms to the orthogonality rules of three-dimensional space. By using the three-axis splicing to form a rotation matrix and converting it to Euler angles, standardized rotation parameters that can be directly recognized by the 3D modeling engine can be output without additional coordinate transformation processing, improving the convenience of model attitude assignment.
