Description

Technical Field

[0001] The present invention relates to data processing technologies, and in particular, to a method and device for dynamically simulating icing on transmission lines. Background Art

[0002] In the field of power transmission, transmission lines are widely distributed in various complex environments. In cold regions, icing on transmission lines is a common and serious problem. Whenever winter comes, the low-temperature and high-humidity climatic conditions cause ice layers to gradually form on the surface of transmission lines. These ice layers not only increase the weight of the lines, resulting in an increase in the sag of the lines and uneven stress on the towers, but may even cause major accidents such as tower collapse and wire breakage in severe cases. They may also affect the electrical performance of the lines and cause faults such as flashovers, posing a huge threat to the safe and stable operation of the power system.

[0003] Currently, there are many deficiencies in traditional methods for simulating icing on transmission lines. The existing technologies fail to fully consider the actual basic attributes of transmission lines, such as line materials, diameters, etc. This results in a large difference between the simulated transmission lines and the actual physical characteristics of the transmission lines. Moreover, the number and distribution of lines will also have a certain impact on the icing detection model, and there is often a lack of in-depth analysis and reasonable handling of the interference areas between lines, making the simulation results unable to accurately reflect the actual situations such as electromagnetic interference between lines and affecting the accuracy of icing detection results.

[0018] The beneficial effects of the present invention are as follows: 1. The present invention can construct a simulation icing detection model according to the line attributes and layout of the actual transmission line, improving the accuracy of transmission line icing detection. First, the present invention can generate simulation units according to the basic attributes of the line, and then generate a long-span model based on the relative positions of the simulation units, and perform aggregation processing on the long-span to obtain an aggregation model, reducing the device volume of the detection device while realizing the icing detection function, which is convenient for the installation of the detection device in actual applications. Second, the present invention can receive the line parameters of the detection device and adjust the temperature of the simulation unit according to the line parameters, thereby improving the accuracy of the icing information.

[0019] 2. By analyzing the basic attributes such as the material properties and diameter properties of each line in the target tower group, the present invention generates a simulated line that highly matches the actual physical characteristics. Among them, the present invention groups the simulated lines according to the joint relationship of the lines, flexibly determines the single line and the joint line, and then obtains the horizontal and vertical relative positions of the simulation unit, determines the suspension distance and suspension height, so as to update the weighing unit and the connection unit of the preset monitoring device, and finally constructs a large-span model.

Detailed implementation manners

[0023] The technical solutions of the present invention will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0024] As Figure 1 shown, the present invention provides a method for dynamically simulating icing on a transmission line, including: S1. Generate simulation units according to the basic attributes of each line of the target tower group, and generate a long-span model based on the relative positions of the simulation units. The simulation units include single lines and / or combined lines.

[0025] It can be understood that each line in the target tower group has different characteristics. By analyzing and processing the basic attributes, simulation units are generated. The simulation unit is a simulation model of the actual transmission line. It can be a single line or a combined line, which can improve the accuracy of simulating the actual transmission line. Moreover, multiple simulation units can be combined according to the relative positions between the simulation units to generate a long-span model.

[0026] Among them, the target tower group is a combination of poles and towers connected at both ends of the transmission line, the basic attributes are the line attributes corresponding to the transmission line, which may include the material and diameter of the line, etc., the simulation unit is a line unit for simulating the transmission line, the long-span model is a simulation model with a relatively large interval between simulation units, the single line is a line with a single quantity, and the combined line is a line formed by combining multiple lines.

[0027] It is not difficult to understand that the long-span model can reflect the layout and mutual relationship of the transmission line in space, and provide a framework model for subsequent simulation and analysis of the icing situation of the transmission line.

[0028] In some embodiments, the specific implementation manner in step S1 (generating simulation units according to the basic attributes of each line of the target tower group) includes: S11. Generate simulation lines according to the basic attributes of each line of the target tower group. The basic attributes include material attributes and diameter attributes.

[0029] It is understandable that the material properties and diameter properties of transmission lines have an important impact on the performance of the lines in an icing environment. For lines made of different materials, their characteristics such as thermal conductivity and mechanical strength are different, and the mechanical responses and electrical performance changes during icing will also vary. The size of the line diameter will affect the windward area, weight, and ice accretion of the line. Generating simulated lines based on these basic properties of each line in the target tower group can make the simulated lines as physically close as possible to the actual lines, thereby improving the accuracy of subsequent simulation results.

[0030] Among them, the material property is the property information of the corresponding material of the line, and the diameter property is the diameter information of the corresponding line.

[0031] It is not difficult to understand that the length of the simulated line can be obtained by multiplying the interval distance between actual target tower groups by the simulation conversion ratio, so as to select a section of distance for icing simulation of the corresponding transmission line.

[0032] S12. Obtain the joint relationship of each of the simulated lines, and group the simulated lines according to the joint relationship to obtain a plurality of simulation groups.

[0033] It is understandable that in actual transmission lines, there may be a joint relationship between different lines. For example, wire clamps are used to join multiple lines into a whole to prevent the lines from crossing under the influence of wind. At the same time, the joint relationship of multiple transmission lines will affect the overall performance and icing situation of the lines. Obtaining the joint relationship of each simulated line and grouping the simulated lines to obtain a plurality of simulation groups can group the lines with a joint relationship together, which is convenient for subsequently constructing a simulation unit that conforms to the actual line.

[0034] Among them, the joint relationship is the associated positional relationship of the simulated lines, and the simulation group is a combination of multiple model lines.

[0035] S13. When it is determined that the joint quantity corresponding to the simulation group is less than 2, obtain a single line according to the simulated lines corresponding to the simulation group.

[0036] It is understandable that when the joint quantity is less than 2, it means that there is only one line in the simulation group. At this time, the simulated line corresponding to this simulation group can be directly used as a single line for processing.

[0037] Among them, the single line is a basic form of the simulation unit, and this judgment and processing method conforms to the actual situation. The joint quantity is the number of simulated lines in the simulation group.

[0038] S14. When it is determined that the joint quantity corresponding to the simulation group is greater than or equal to 2, obtain a joint line according to the multiple simulated lines corresponding to the simulation group.

[0039] It can be understood that when the number of combinations corresponding to the simulation group is greater than or equal to 2, it indicates that there are multiple simulation lines in the simulation group. Obtaining the combined line based on the multiple simulation lines corresponding to the simulation group can more comprehensively simulate the complex situations in the actual transmission line, making the simulation results closer to the real scenario.

[0040] In some embodiments, the specific implementation manner of step S14 (obtaining the combined line according to the multiple simulation lines corresponding to the simulation group) includes: S141, obtaining the relative positions of the simulation lines in the simulation group.

[0041] It can be understood that different relative positions will cause differences in the mechanical structure, electrical performance, etc. of the combined line. For example, in the actual transmission line, the relative position relationships such as the spacing and arrangement between lines will affect the electromagnetic field distribution of the lines, the force conditions during icing, etc. Therefore, obtaining the relative positions of the simulation lines in the simulation group can provide a basis for accurately positioning and connecting the simulation lines subsequently, making the generated combined line more in line with the characteristics of the actual transmission line.

[0042] S142, positioning the simulation lines according to the relative positions and retrieving simulation line clamps to connect the simulation lines to obtain the combined line.

[0043] It can be understood that the transmission lines and their corresponding positions are determined according to the line clamps in the actual line. For example, when 4 lines in the line group are fixedly combined, and the No. 1 simulation line and the No. 2 simulation line are above the No. 3 simulation line and the No. 4 simulation line, the simulation line clamps for connecting the 4 lines can be retrieved to fix the corresponding simulation lines to obtain the combined line.

[0044] Among them, the simulation line clamp is a model corresponding to the actual distance-adjusting line clamp, and the simulation line clamp plays a role in fixing and connecting in the combined line.

[0045] It is not difficult to understand that by using the simulation line clamps to connect the simulation lines, multiple simulation lines can be combined into an organic whole, thereby obtaining a combined line that meets the requirements, providing a more realistic model for the subsequent dynamic simulation of transmission line icing.

[0046] In some embodiments, the specific implementation manner of step S1 (generating a long-span model based on the relative positions of the simulation units) includes: S15, obtaining the horizontal relative positions and vertical relative positions of the simulation units.

[0047] It can be understood that in order to make the subsequent large-span model more in line with the actual situation and improve the accuracy of line icing simulation, the horizontal relative position and numerical relative position of the simulation unit can be obtained, so as to determine the installation position of the simulation unit according to the horizontal relative position and vertical relative position in the subsequent process, and improve the accuracy of the large-span model.

[0048] Among them, the horizontal relative position is the relative position in the horizontal direction, which can determine the arrangement order and interval distance of each simulation unit in the horizontal direction. The vertical relative position is the position of the simulation unit in the vertical direction, and the suspension height difference of the line in the vertical direction can be determined through the vertical relative position.

[0049] S16. Determine the suspension spacing according to the horizontal relative position, and determine the suspension height based on the vertical relative position.

[0050] It can be understood that after obtaining the horizontal relative position of the simulation unit, the suspension spacing between different simulation units can be determined. In the actual transmission line, an appropriate suspension spacing can avoid mutual interference between lines and reduce problems such as line collisions caused by factors such as wind deflection. Similarly, the suspension height will affect the ground clearance of the line, the force condition during icing, etc. Accurately determining the suspension spacing and suspension height helps to construct a large-span model that better meets the actual operation requirements.

[0051] Among them, the suspension spacing is the horizontal interval distance between the suspension lines, and the suspension height is the height distance at which the line is suspended in the air.

[0052] It is worth mentioning that after determining the horizontal relative position and vertical relative position between each line, the suspension spacing can be obtained through the numerical difference of the horizontal phase position, and the suspension height of the simulation line can be determined according to the numerical difference of the vertical relative position.

[0053] S17. Invoke the preset monitoring device, update the weighing unit of the preset monitoring device according to the suspension spacing, and determine the connection unit of each weighing unit based on the suspension height.

[0054] It can be understood that the preset monitoring device is used to monitor various parameters of the simulation unit, such as weight change, etc., in the dynamic simulation of transmission line icing to reflect the icing situation. Different suspension spacings will affect the gravity distribution of the simulation unit, etc. Therefore, it is necessary to update the weighing unit of the preset monitoring device according to the suspension spacing to ensure that the weight of the simulation unit can be accurately measured. At the same time, different suspension heights will affect the connection method between the simulation unit and the monitoring device. Determining the connection unit of each weighing unit based on the suspension height can ensure the effective connection between the monitoring device and the simulation unit and make the monitoring data accurate and reliable.

[0055] Among them, the preset monitoring device is a pre-set monitoring device, which has equipment units such as a monitoring unit and a meteorological sensor for monitoring the icing situation. The weighing unit is an equipment unit for weighing, and the connecting unit is an equipment unit for connecting the weighing unit and the simulation unit, such as a connecting rod.

[0056] S18. Connect to the corresponding simulation unit according to the connecting unit to generate a long-span model.

[0057] It can be understood that, as Figure 2 shown, the connecting unit is determined according to the suspension height. It stipulates the connection distance between the simulation unit and the weighing unit. Connect the corresponding simulation unit according to the connecting unit, that is, combine each simulation unit with the weighing unit, so as to connect multiple simulation units to the preset monitoring model to generate the final long-span model. The long-span model can relatively realistically simulate the layout and state of the actual transmission line, providing a reliable basis for subsequent icing simulation and analysis.

[0058] S2. Obtain the interference area of the simulation unit, and perform position aggregation on the simulation units in the long-span model according to the interference area to obtain the aggregation model corresponding to the detection device.

[0059] It should be noted that since each transmission line will generate a magnetic field when transmitting current, when the transmission lines are close, interference may be generated through mutual inductance and capacitive coupling. Therefore, it is necessary to determine the interference area of each simulation unit so that there is a certain interval distance between each simulation unit to prevent interference between the lines. At the same time, when the interval distance between the lines is large, it will have a certain impact on the volume of the model. For example, the larger the interval, the larger the volume of the generated model. Furthermore, the long-span model can be adjusted according to the interference area, that is, on the premise that the lines do not interfere, the volume of the model is reduced as much as possible. For subsequent application in actual monitoring, it is convenient for the installation of equipment and improves the installation efficiency of the detection equipment. Thus, the position of the simulation unit can be aggregated, that is, the distance between the simulation units can be adjusted, and then the aggregation model corresponding to the detection device can be obtained.

[0060] It can be understood that the interference area is the interference range area that causes an impact, that is, the area affected by the line magnetic field in the simulation unit. The detection device is a device for detecting the icing situation of the transmission line, and the aggregation model is the simulation model corresponding to the detection device, that is, the model obtained after performing position aggregation on the simulation units of the long-span model.

[0061] In some embodiments, the specific implementation manner in step S2 (the obtaining of the interference area of the simulation unit) includes: S21. Obtain the preset interference radius of the simulation line.

[0062] It is understandable that the interference radius is the maximum radius distance at which the simulated line may interfere with the surrounding environment or other lines in space, and is preset according to factors such as the physical characteristics, electrical characteristics of the simulated line, and the possible influence range.

[0063] Through the above embodiments, the interference radius of the simulated line of the present invention can be obtained, so as to subsequently determine the interference area of each simulation unit.

[0064] S22, generate the interference area corresponding to the single line according to the interference radius corresponding to the simulated line in the single line.

[0065] It is understandable that a single line is composed of one simulated line. According to the interference radius corresponding to this simulated line, the interference area corresponding to the single line can be generated.

[0066] Among them, the interference area can be a spatial range formed with the simulated line as the center and the interference radius as the radius. Within the interference area, the single line may affect other simulation units. By determining the interference area of the single line, the influence range of the single line in space can be clearly determined, providing basic information for subsequent position aggregation operations.

[0067] S23, generate the initial interference area corresponding to the combined line based on the interference radii corresponding to the simulated lines in the combined line.

[0068] It is understandable that a combined line is composed of multiple simulated lines. For each simulated line in the combined line, there is its corresponding interference radius. According to the interference radii of all simulated lines, the influence range of each simulated line can be determined respectively, and then the initial interference area corresponding to the combined line can be generated. Since the positions and mutual relationships of the simulated lines in the combined line are relatively complex, the initial interference area can be a combination of multiple spatial ranges with each simulated line as the center and the corresponding interference radius as the radius.

[0069] Among them, the initial interference area is the interference area corresponding to each combined line.

[0070] It is not difficult to understand that the initial interference area reflects the respective influence ranges of the simulated lines in the combined line, providing a basis for further determining the overall interference area of the combined line.

[0071] S24, perform a summary process on each of the initial interference areas to obtain the interference area corresponding to the combined line.

[0072] It can be understood that the initial interference area corresponding to the combined line is a preliminary manifestation of the respective influence ranges of each analog line. In order to obtain an interference area that can accurately reflect the overall influence range of the combined line, it is necessary to summarize the initial interference areas, and finally obtain a unified interference area that can represent the overall interference situation of the combined line. This interference area can more accurately describe the influence range of the combined line on other analog units in space, providing a more accurate basis for subsequent position aggregation.

[0073] In some embodiments, the specific implementation manner in step S24 (summarizing the initial interference areas to obtain the interference area corresponding to the combined line) includes: S241, determining the regional centers of the initial interference areas.

[0074] It can be understood that in order to subsequently determine an interference area that can include all the initial interference areas corresponding to the combined line, the regional centers of the initial interference areas can be preferentially determined, so as to subsequently summarize multiple initial interference areas.

[0075] Among them, the regional center is the center point of the initial interference area.

[0076] S242, obtaining the leftmost regional center as the first horizontal center, obtaining the rightmost regional center as the second horizontal center, and determining the horizontal position according to the middle position between the first horizontal center and the second horizontal center.

[0077] It can be understood that after obtaining the regional centers of the initial interference areas, analyzing these centers in the horizontal direction, obtaining the leftmost regional center as the first horizontal center and the rightmost regional center as the second horizontal center. The first horizontal center and the second horizontal center determine the boundary range of all the initial interference areas in the horizontal direction. Among them, the middle position between the first horizontal center and the second horizontal center can be calculated to obtain the center position that can represent the initial interference area of the combined line in the horizontal direction. This horizontal position helps to determine the horizontal positioning of the overall interference area of the combined line.

[0078] Among them, the first horizontal center is the regional center located on the leftmost side, the second horizontal center is the regional center located on the rightmost side, and the horizontal position is the center coordinate position of the analog unit corresponding to the combined line in the horizontal direction.

[0079] S243, obtaining the uppermost regional center as the first vertical center, obtaining the lowermost regional center as the second vertical center, and determining the vertical position according to the middle position between the first vertical center and the second vertical center.

[0080] It can be understood that, similar to the processing in the horizontal direction, in the vertical direction, the uppermost region center is obtained as the first vertical center, and the lowermost region center is obtained as the second vertical center. The first vertical center and the second vertical center define the boundaries of the initial interference region in the vertical direction. Calculate the intermediate position between the first vertical center and the second vertical center, so as to determine the center position of the initial interference region of the combined circuit in the vertical direction. Through the vertical position, the positioning of the overall interference region of the combined circuit in the vertical direction can be determined.

[0081] S244, determine the interference center based on the horizontal position and the vertical position, and generate an interference region covering each of the initial interference regions according to the interference center.

[0082] It can be understood that the interference center is determined according to the horizontal position and the vertical position. For example, when the coordinate corresponding to the horizontal position is 6 and the coordinate corresponding to the vertical position is 5, the interference center can be obtained as the position point corresponding to (6, 5). Thus, a circular region can be constructed outward around the interference center until the generated region completely covers all the initial interference regions. Then, the corresponding region can be used as the interference region of this simulation unit.

[0083] In some embodiments, the specific implementation manner of step S2 (wherein the simulation units in the long-span model are position-aggregated according to the interference region) includes: S25, determine the positioning center of the interference region of each simulation unit, mark the positioning center closest to the corresponding weighing unit as the reference center, and determine the corresponding interference region as the reference region.

[0084] It can be understood that in order to minimize the model volume to the greatest extent, the positioning center closest to the weighing unit can be used as the reference center, so that it can be used as a reference position for subsequent operations, enabling the remaining simulation units to move their positions closer to the model main body corresponding to the weighing unit, so as to achieve the position aggregation of the simulation units and reduce the model volume.

[0085] Among them, the positioning center is the center point of the interference region corresponding to the simulation unit, the reference center is the positioning center closest to the weighing unit, and the reference region is the interference region corresponding to the reference center.

[0086] S26, move each of the interference regions according to the reference center and the reference region to generate a movement route.

[0087] It can be understood that after determining the reference center and the reference region, it is necessary to move the other interference regions according to them to achieve the position aggregation of the simulation units.

[0088] Among them, the movement route is the route for the interference regions to move in position. The movement route clarifies how each interference region should move to be reasonably aggregated with the reference region. By reasonably planning the movement route, the distribution of the simulation units in space can be made more compact and orderly, facilitating the subsequent detection device to more effectively detect and analyze the aggregated model.

[0089] In some embodiments, the specific implementation manner of step S26 (wherein each of the interference regions is moved according to the reference center and the reference region to generate a movement route) includes: S261, obtain the positioning center adjacent to the reference center as the movement center.

[0090] It should be noted that when generating the movement route, first, the target and starting point of the movement need to be determined. Obtain the positioning center adjacent to the reference center as the movement center. The movement center is the core position of the interference region to be moved currently. The adjacent positioning center means that the corresponding interference region is relatively close to the reference region in space. Starting from here for movement can more efficiently achieve the connection of the interference regions and the aggregation of the simulation units.

[0091] It can be understood that when moving the interference regions in position, the interference regions adjacent to the reference center can be preferentially moved so that all the interference regions can be aggregated within a certain area subsequently.

[0092] Among them, the movement center is the positioning center adjacent to the reference center, that is, the positioning center of the interference region that needs to be moved in position.

[0093] S262, starting from the movement center and ending at the reference center, move the interference region corresponding to the movement center until the interference region is connected to the reference region to generate a movement route.

[0094] It can be understood that by connecting the movement center and the reference center, moving the interference region corresponding to the movement center along the connection line towards the reference center until the interference region is connected to the reference region, a movement route can be obtained, that is, the route of the movement center.

[0095] S263, take the movement center as the new positioning center, and take the interference region corresponding to the movement center as the new reference region, and repeat the above steps of generating the movement route until the connection of the interference regions stops.

[0096] It can be understood that after completing the movement of an interference region once, take the movement center as the new positioning center and its corresponding interference region as the new reference region, and then repeat the above steps of generating the movement route, continuously move the adjacent interference regions in sequence and connect them to the already aggregated region until all the interference regions are connected and then stop.

[0097] Through the above embodiments, it can be ensured that the interference regions of all simulation units can be reasonably aggregated together to form a tight whole.

[0098] S27. Based on the moving route, control the simulation units to follow the movement for position aggregation.

[0099] It can be understood that after generating the moving routes of all interference regions, the simulation units are controlled to follow the movement according to the moving routes. The movement of the simulation units is carried out according to the moving routes of the interference regions, because the interference regions reflect the influence range of the simulation units in space. By controlling the movement of the simulation units, the position aggregation of the simulation units in space is achieved, and finally the aggregation model corresponding to the detection device is obtained.

[0100] It is not difficult to understand that the aggregation model can more clearly display the mutual relationship and influence range between the simulation units, so as to better simulate the actual situation of ice coating on transmission lines.

[0101] S3. Determine the line parameters of each line in the detection device, and control the temperature of each line in the simulation unit according to the line parameters.

[0102] It can be understood that in the simulation of ice coating on transmission lines, the temperature of the line will affect the formation and development of ice coating. The detection device can obtain the line parameters of each line, and the line parameters reflect the current operating state of the line. Among them, the line parameter is the temperature generated by the heat dissipated by the current transmitted by the line. By controlling the temperature of each line in the simulation unit according to the line parameters, the simulated environment can be made closer to the actual situation, thereby improving the accuracy of ice coating simulation.

[0103] Among them, the line parameter is the corresponding temperature of the line in the detection device.

[0104] In some embodiments, the specific implementation manner in step S3 (determining the line parameters of each line in the detection device and controlling the temperature of each line in the simulation unit according to the line parameters) includes: S31. Obtain the line flow of each line according to the detection device, perform comparison processing on a preset form based on the line flow, and determine the line parameters corresponding to each line. The preset form includes the one-to-one correspondence between the line flow and the line parameters.

[0105] It can be understood that different current flows in line transportation will also have a certain impact on the temperature of the line. The preset form is established in advance based on a large amount of experimental data and theoretical analysis, which records the divergence temperatures of the lines corresponding to different line flows. By comparing the detected line flow with the preset form, the line parameters corresponding to the current line flow can be found from the form, so as to accurately determine the temperatures that each line should simulate according to the actual line operation status, providing a clear target for subsequent temperature control.

[0106] Among them, the line flow is the current flow of the electric energy transported by the corresponding line, the preset form is preset, including the line flow and the corresponding line parameters, and the line parameters are the divergence temperatures corresponding to the lines.

[0107] S32. Based on the simulated temperature, control the heating wire of the corresponding simulated line for temperature regulation.

[0108] It can be understood that after determining the simulated temperatures corresponding to each line, the temperature of the heating wire can be regulated, so as to control each simulated line to reach the corresponding simulated temperature.

[0109] It is not difficult to understand that a heating wire is set in the simulated line. The heating wire can change the heating power by adjusting the current magnitude and other means, so as to achieve temperature control. Operate the heating wire of the corresponding simulated line according to the obtained simulated temperature, so that its heating power changes, and then adjust the temperature of the simulated line to the target simulated temperature to ensure that the simulated environment conforms to the operation conditions of the actual line.

[0110] S4. Obtain the detection data of each of the simulated units, and generate icing information according to the detection data.

[0111] It can be understood that after completing operations such as the construction, position aggregation, and temperature regulation of the simulated units, the simulated units are in an environment relatively close to the actual icing situation of the transmission line. At this time, by obtaining the detection data of each simulated unit, these detection data may include information such as the weight change, temperature change, and stress change of the simulated unit. Through the obtained detection data and analysis and processing according to a specific algorithm, icing information such as the thickness, weight, and distribution of the ice can be generated.
