Description

TECHNICAL FIELD

[0001] The application belongs to the field of data analysis, and specifically relates to a dense power transmission channel mobile route planning method and system based on operation and maintenance information. BACKGROUND

[0002] In the field of intelligent operation and maintenance of power systems, mobile operation equipment (such as inspection unmanned aerial vehicles and robots) faces severe safety challenges when passing through dense power transmission channels. Such channels generally have high-density layout characteristics such as multi-circuit lines on the same tower, AC-DC hybrid connection, and compact corridors, resulting in highly complex spatial electromagnetic field distribution. However, existing route planning techniques have the following defects:

[0003] Fault impact analysis is not performed, making it difficult to identify potential risks in the inspection route in a timely manner, which may result in equipment or personnel operating in high-risk areas, thereby increasing the risk of personal safety and equipment damage; in dense power transmission channels, lines are close to each other, and a fault in a certain route may affect the stability of adjacent lines, and the lack of fault impact analysis may cause this chain reaction to be ignored, leading to the expansion of the fault and the intensification of the impact range; without analyzing the fault impact of each inspection route in advance, it is difficult to quickly determine the affected area and key points when a fault occurs, which delays the repair time, reduces the emergency response efficiency, and affects the overall stable operation of the power transmission system; route planning does not consider fault impact, which may result in a high risk in the selected route in actual operation, increasing the operation difficulty and fault occurrence probability, and reducing the effectiveness and safety of equipment operation; failure to analyze fault impact may result in hidden dangers that are not promptly identified and addressed, increasing the frequency and severity of faults, thereby increasing maintenance costs and power loss and reducing system economic benefits; in order to solve the problems raised in the background, the application designs a dense power transmission channel mobile route planning method and system based on operation and maintenance information.

[0037] In order to better understand the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings.

[0038] To solve the technical problems proposed in the background art, the present application provides a preferred embodiment:

[0039] The specific content of the present embodiment is:

[0040] As Figure 1 shown, the dense power transmission channel mobile route planning method based on operation and maintenance information includes the following specific steps:

[0041] S1, obtain the environmental information data, channel density and layout state data and historical influence data of each section of the power transmission channel in each mobile route due to electromagnetic interference;

[0042] In this embodiment, the specific steps of S1 are: the environmental information data includes terrain complexity data and visibility data, the terrain complexity data is obtained by: obtaining the required regional DEM (DEM is a format that represents the elevation data of the earth's surface in grid form) data from a professional geographic data platform (such as geographic spatial data cloud, national glacier permafrost desert scientific data center and Zenodo scientific data set platform), and then using GIS (such as QGIS or ArcGIS) software to analyze and process the required regional DEM data, and calculate the required terrain slope value data; obtain the required regional remote sensing image data (such as Sentinel-2 or Landsat data), and process the required regional remote sensing image data to identify the required regional water system distribution data; the visibility data is obtained by: obtaining the visibility data of the required region during the future device operation through the API of the weather website, application or weather station; the influence data of each section of the power transmission channel in each mobile route due to electromagnetic interference is obtained by: obtaining the coupling voltage state data of each section of the power transmission channel in each mobile route from the historical operation and maintenance records; the channel density and layout state data of each mobile route is obtained by: obtaining the line spacing value of each section of the power transmission channel in each mobile route from the engineering research report (such as in a certain project, when 1000kV AC line (double circuit on the same tower) is parallel to ±800kV DC line, the minimum spacing should be 62 meters), and obtaining the average value data of the channel line spacing of each mobile route by the line spacing value of each section of the power transmission channel; obtaining the number of single-base towers connected to multiple return lines from the tower design report of each section of the power transmission channel in each mobile route.‌

[0043] S2, analyze the environmental impact of each mobile route according to the environmental information data corresponding to each section of the power transmission channel in each mobile route;

[0044] S21, analyze the terrain impact of each section of the power transmission channel in each mobile route based on the terrain complexity data corresponding to each section of the power transmission channel in each mobile route;

[0045] In the embodiment, S21 comprises the following specific steps: performing terrain influence analysis on the power transmission passages in each section of each mobile route based on the terrain complexity data corresponding to the power transmission passages; wherein the terrain influence analysis on the power transmission passages in each section of each mobile route is performed in the following manner: obtaining terrain slope data and water system distribution data corresponding to the power transmission passages in each section of each mobile route; dividing the difference between the maximum value and the minimum value of the terrain slope of the power transmission passages in each section of each mobile route by the difference between the average value and the minimum value of the terrain slope, to quantify the slope change of the power transmission passages in each section of each mobile route; dividing the water system distribution density corresponding to the power transmission passages in each section of each mobile route by the reference water system distribution density, to quantify the water system complexity of the power transmission passages in each section of each mobile route; weighting and summing the slope change and the water system complexity of the power transmission passages in each section of each mobile route, to obtain the terrain influence analysis result of the power transmission passages in each section of each mobile route; it should be noted that the normalization processing manner of "(maximum value-minimum value) / (average value-minimum value)" effectively eliminates the influence of scale difference; through the ratio of the slope range and the average value, the slope fluctuation amplitude is reflected, and the interference of absolute elevation is avoided, which is consistent with the core principle of the slope in the topographic map (slope equals to elevation / horizontal distance); the ratio of the water system distribution density and the reference density realizes the horizontal comparability of different basin data; the slope change and the water system complexity are superimposed, and the weight is allowed to be adjusted according to the engineering requirement (for example, the water system weight can be increased in the high mudflow area, and the slope index is focused on in the steep slope area), which has higher flexibility than the traditional table lookup method, integrates the slope (terrain element) and the water system (hydrological element), and comprehensively reflects the comprehensive influence of the terrain on the equipment operation, compared with the single index (such as the strip method).

[0046] S22, performing meteorological influence analysis on the power transmission passages in each section of each mobile route based on the visibility data corresponding to the power transmission passages;

[0047] In the embodiment, S22 comprises the following specific steps: performing meteorological influence analysis on each section of the power transmission channel in each mobile route based on the visibility data corresponding to each section of the power transmission channel in each mobile route; wherein the meteorological influence analysis process corresponding to each section of the power transmission channel in each mobile route comprises the following steps: obtaining the visibility data corresponding to each section of the power transmission channel in each mobile route; dividing the difference between the visibility data corresponding to each section of the power transmission channel in each mobile route and the minimum allowable value of the visibility by the reference visibility difference to quantify the deviation degree of the visibility from the minimum allowable value when the prediction device is working in each section of the power transmission channel; it should be noted that the reason for selecting visibility to analyze the meteorological influence of each section of the power transmission channel in each mobile route is that when the device is working in the dense power transmission channel, the visibility is a core factor directly determining the safety and effectiveness of the device working, once the visibility is too low, the device cannot meet the basic obstacle avoidance analysis time, the probability of collision when the device is working is greatly increased, and at the same time, due to the low visibility, the effectiveness of the data collected when the device is working is also greatly reduced.

[0048] S23, obtaining the environmental influence analysis result of each mobile route from the terrain influence analysis result and the meteorological influence analysis result of each section of the power transmission channel in each mobile route;

[0049] In the embodiment, S23 comprises the following specific steps: obtaining the terrain influence analysis result and the meteorological influence analysis result of each section of the power transmission channel in each mobile route, weighting and summing the terrain influence analysis result and the meteorological influence analysis result of each section of the power transmission channel in each mobile route to obtain the environmental influence analysis result of each section of the power transmission channel in each mobile route, and summing and averaging the environmental influence analysis result of each section of the power transmission channel in each mobile route to obtain the environmental influence analysis result of each mobile route; it should be noted that the influence of the external environment on the device working in each mobile route is comprehensively evaluated by superimposing the difficulty of the device working in each mobile route in the dense power transmission channel, and reasonable weight distribution is performed, thereby improving the accuracy of the environmental influence analysis.

[0050] S3, performing mobile route danger analysis according to the influence data of each section of the power transmission channel in each mobile route due to electromagnetic interference and the environmental influence analysis result of each mobile route;

[0051] In the embodiment, the specific steps of S3 are as follows:

[0052] S31, performing electromagnetic interference influence analysis of each mobile route according to the influence data of each section of the power transmission channel in each mobile route due to electromagnetic interference;

[0053] In the embodiment, the specific steps of S31 are as follows:

[0054] S311, obtain the coupling voltage state data of each section of the power transmission channel in each historical moving route, and perform electromagnetic interference influence analysis on each section of the power transmission channel in each historical moving route based on the coupling voltage state data of each section of the power transmission channel in each historical moving route, wherein the electromagnetic interference influence analysis method is: dividing the difference between the maximum and minimum coupling voltage fluctuation values of each section of the power transmission channel in each historical moving route by the reference coupling voltage fluctuation value to quantify the fluctuation stability of the coupling voltage of each section of the power transmission channel in each moving route; dividing the average coupling voltage of each section of the power transmission channel in each historical moving route by the reference coupling voltage to quantify the interference degree of each section of the power transmission channel in each moving route to the equipment; weighting and adding the fluctuation stability of the coupling voltage of each section of the power transmission channel in each moving route and the interference degree to the equipment to obtain the electromagnetic interference influence analysis result of each section of the power transmission channel in each moving route; It should be noted that during power transmission, especially for high-voltage transmission lines, the electromagnetic waves generated by them may be coupled to other equipment or lines through power lines, conductors or other adjacent conductive media. This coupling voltage is generated through electromagnetic induction or electromagnetic coupling effect; the strong electric field and magnetic field generated by the high-voltage power lines in the dense power transmission channel may be coupled to the nearby equipment or electrical systems through adjacent conductors or power facilities (such as power towers, overhead lines, underground cables, etc.), causing interference (such as magnetic field interference and electric field interference) to the nearby equipment or electrical systems. Magnetic field interference: When high-voltage current flows through the transmission line, the change in current will generate a magnetic field, which will affect the surrounding conductors, especially when high current flows, the magnetic field is stronger; Electric field interference: Voltage changes on the transmission line will generate an electric field on the surrounding conductors, which will induce a coupling voltage, which may have adverse effects on surrounding electronic equipment, control systems or communication equipment (such as generating electrical noise, signal interference or equipment failure), when the coupling voltage is too large, it may cause voltage fluctuations, overload or damage to power equipment (such as transformers, switchgear, etc.); By superimposing the fluctuation stability of the coupling voltage and its interference degree to the equipment to analyze the electromagnetic interference influence, and by reasonably distributing the weights of the fluctuation stability of the coupling voltage and its interference degree to the equipment, the accuracy of the electromagnetic interference influence analysis result is improved.

[0055] S312, obtaining the electromagnetic interference influence analysis result of each section of the power transmission channel in each mobile route, summing the electromagnetic interference influence analysis result of each section of the power transmission channel in each mobile route, and averaging the sum to obtain the electromagnetic interference influence analysis result of each mobile route. It should be noted that the operation of summing and averaging the electromagnetic interference influence analysis result of each section of the power transmission channel in each mobile route can remove the influence of extreme results in the electromagnetic interference influence analysis result on the overall result, quantify the trend of the electromagnetic interference influence analysis result, smooth the fluctuation range of the electromagnetic interference influence analysis result data, and improve the accuracy of the electromagnetic interference influence analysis result of each mobile route.

[0056] S32, performing danger analysis of each mobile route based on the electromagnetic interference influence analysis result and the environmental influence analysis result of each mobile route.

[0057] In this embodiment, the specific steps of S32 are as follows: obtaining the electromagnetic interference influence analysis result of each mobile route, weighting and adding the electromagnetic interference influence analysis result of each mobile route and the environmental influence analysis result to obtain the danger analysis result of each mobile route. It should be noted that complex terrain and low-visibility environment constitute external interference when the device is operating, which makes the device face higher risk and uncertainty when operating, and may cause the device to malfunction and affect the normal operation of the device. The coupling voltage generated by the power transmission channel may also interfere with the operation of the device, especially when high-voltage current passes through, electromagnetic interference may affect the normal operation of the device, and may even cause the device to malfunction or data error, reducing the safety and efficiency of the device when operating. By comprehensively considering the external environmental influence factors and superimposing the interference of the power transmission channel to the device, the danger analysis result of the device in each mobile route is obtained, and by reasonably distributing the weights, the danger in the mobile route can be more accurately analyzed, and the safety of the device when operating is improved.

[0058] S4, performing danger influence analysis of each mobile route based on the danger analysis result of each mobile route and the channel density and layout state data of each mobile route.

[0059] In the embodiment, the specific steps of S4 are as follows: obtaining the analysis results of the risk of each mobile route, the average data of the distance between the channel lines, and the data of the number of multi-circuit lines connected to a single tower, dividing the difference between the average data of the distance between the channel lines of each mobile route and the minimum value of the distance between the channel lines by the reference difference value of the distance between the channel lines, quantifying the risk degree of each mobile route due to the inappropriate distance between the channel lines; dividing the data of the number of multi-circuit lines connected to a single tower in each mobile route by the reference data of the number of multi-circuit lines connected to a single tower, quantifying the influence diffusion degree of each mobile route due to the fault of the multi-circuit lines connected to a single tower; multiplying the risk degree of each mobile route due to the inappropriate distance between the channel lines by the influence diffusion degree due to the fault of the multi-circuit lines connected to a single tower, quantifying the dangerous influence diffusion degree in each mobile route; multiplying the dangerous influence diffusion degree in each mobile route by the analysis results of the risk of each mobile route, obtaining the analysis results of the dangerous influence of each mobile route; it should be noted that the reason for selecting the average data of the distance between the channel lines and the data of the number of multi-circuit lines connected to a single tower to analyze the dangerous influence is that: the channel lines need sufficient safety distance (for example, 12-14 meters of horizontal distance is required for double-circuit vertical arrangement, and 6-8 meters of horizontal distance can be narrowed for same-side vertical arrangement (F-type tower)), and too small distance between the channel lines will increase the risk of cascading failure (for example, the collapse or broken wire of a single tower may affect the adjacent lines); the number of multi-circuit lines connected to a single tower in each mobile route refers to the number of lines greater than or equal to 2, and the multi-circuit lines connected to a single tower can also be called shared tower, which is a typical weak point in dense power transmission channel, and the fault of the shared tower may cause all the connected lines to stop running at the same time (for example, when the number of lines connected to a single tower is greater than or equal to 3, if the single tower fails, the probability of total stop caused by the failure will increase by 4.7 times); by multiplying the risk due to the inappropriate distance between the channel lines and the influence diffusion degree due to the fault of the single tower, the mutual influence of the risk due to the inappropriate distance between the channel lines and the influence diffusion degree due to the fault of the single tower in the mobile route is quantified, because when the distance between the channel lines is inappropriate, if a dangerous situation (such as collision and tower collapse) occurs, the more the number of lines connected to the tower, the greater the influence.

[0060] S5, obtaining the optimal mobile route according to the analysis results of the dangerous influence of each mobile route, and taking the obtained optimal route as the equipment operation route.

[0061] For example, Figure 2As shown, in this embodiment, the specific steps of S5 are as follows: obtain the hazard impact analysis results of all movement routes, sort all the hazard impact analysis results of all movement routes in ascending order, and take the movement route corresponding to the smallest hazard impact analysis result as the optimal movement route, and take this route as the equipment operation route; it should be noted that the hazard impact of each movement route is sorted in descending order to obtain the safest route, thereby improving the safety of equipment operation.

[0062] Based on the above implementation, this embodiment has the following advantages over the prior art: This embodiment acquires environmental information data, channel density and layout status data, and historical impact data of electromagnetic interference on each segment of the transmission channel in each mobile route; it analyzes the hazardous impact of each mobile route based on the acquired data to obtain the optimal mobile route; it analyzes the impact of faults on each mobile route, promptly identifies potential risks in the inspection route, and improves the effectiveness and safety of equipment operation; it analyzes the impact of faults on each inspection route in advance, and can quickly determine the affected area and key points when a fault occurs, improving emergency response efficiency and ensuring the overall stable operation of the power transmission system.

[0063] like Figure 3 As shown, this embodiment also provides a dense transmission channel mobile route planning system based on operation and maintenance information. It is implemented based on the aforementioned dense transmission channel mobile route planning method based on operation and maintenance information. Specifically, it includes a mobile route data acquisition module, an environmental impact analysis module, a route hazard analysis module, a hazard impact analysis module, and an optimal route analysis module. The mobile route data acquisition module is used to acquire environmental information data, channel density and layout status data, and historical impact data of electromagnetic interference on each segment of the transmission channel in each mobile route.
