[0019] Other features and advantages of the present disclosure will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

Together with the following specific embodiments, they are used to explain the present disclosure but do not constitute a limitation of the present disclosure. In the accompanying drawings: Figure 1 The diagram is a schematic diagram showing a method for planning a path of electric lines in a wind farm according to an exemplary embodiment of the present disclosure.

[0023] Figure 4 It is a block diagram of an electronic device according to an exemplary embodiment. DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0025] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0026] Wind farm collection lines directly affect the power generation efficiency of wind farms and the stability of power grids, and are an important part of wind farm infrastructure. Reasonable planning of collection lines can reduce power loss, improve power generation efficiency, reduce the failure rate of power grids, and improve the reliability of power grids.

[0027] In the first related technology, when the location of the wind turbine generator set and the location of the booster station in the wind farm are determined, the path corresponding to the wind farm collector line is planned according to the topographic map or electronic map. For example, CAD (Computer-Aided Design) software can be used as the main planning tool, and relevant personnel manually judge the available paths based on the map information and select all feasible path plans. After completing the preliminary selection, the relevant personnel will review the selected path plan on the spot through surveying and mapping instruments. Then, based on the information of the field survey and combined with factors such as path length, construction difficulty, cost, and convenience of operation and maintenance, the optimal path corresponding to the collector line in the wind farm is determined. For example, by establishing a collection of tower groups, the enumeration method is used to meet the preset conditions to plan the line path, or the wind turbines are grouped according to the location of the wind turbine generator set, the location of the substation and the direction of the transmission line, and the path selection is performed manually.

[0028] In the second related technology, the path corresponding to the collector line in the wind farm is planned by using drone technology. Compared with the path plan based on topographic maps, electronic maps and surveying instruments, it can efficiently and accurately obtain high-resolution image data of the wind farm area, providing more detailed and reliable terrain information for path planning. For example, wind turbines can be intelligently grouped by setting constraints, and the line path can be planned using the Dijkstra algorithm.

[0029] However, the inventors found that when planning the path corresponding to the collector line in the wind farm through the first related technology, there is a lack of systematic and scientific planning methods, which is highly dependent on human experience, increasing a lot of manpower and time, while reducing the efficiency of path planning. The data update speed in the map or electronic map is slow, and it is unable to reflect the changes in terrain, new buildings or facilities in a timely manner, which leads to deviations between the planned path and the actual terrain, reducing the accuracy of path planning. The lack of multi-faceted consideration of local environmental factors leads to the planned path not meeting the actual environmental requirements, increasing the difficulty and cost of construction, and may cause damage to the environment.

[0030] When planning the path corresponding to the wind farm collection line through the second related technology, the flight distance, height and load capacity of the drone are subject to certain restrictions, which leads to the fact that the drone may not be able to cover all necessary areas or meet all requirements when planning large or complex wind farm collection lines. When subjected to adverse environments such as strong winds, heavy rains, high temperatures or cold weather, the operation of the drone may be seriously affected and unable to perform normal work.

[0031] In view of this, the present disclosure provides a path planning method and corresponding device for a wind farm collector line to solve the technical problems existing in the above-mentioned related technologies.

[0032] like Figure 1 As shown, Figure 1 is a schematic diagram showing a method for planning a path of a wind farm electric line according to an exemplary embodiment of the present disclosure, with reference to Figure 1 ,include: S101: Acquire power transmission requirements of a wind farm collection line and site survey data around the wind farm, wherein the site survey data includes environmental data around the wind farm and site facility data of the wind farm; S102: Analyze the environmental data to obtain environmental analysis data, and analyze the site facility data to obtain location data of various facilities in the wind farm; S103: generating a plurality of candidate paths corresponding to the collector lines between the wind turbine generator sets in the wind farm and the substation according to the environmental analysis data, the location data and the power transmission demand; S104: Determine the environment data and cost data of each candidate path among the plurality of candidate paths; S105: Perform path planning on the multiple candidate paths according to the environment data and the cost data to obtain a target path.

[0033] Through the above technical solution, according to the environmental analysis data, location data and power transmission requirements of the wind farm, multiple candidate paths corresponding to the wind farm collection line are generated between the wind turbine generator set and the substation, and the multiple candidate paths are planned according to the cost data and environmental data corresponding to each candidate path to obtain the target path. Among them, the environmental analysis data and the location data are obtained by analyzing the site survey data around the wind farm. By using the environmental analysis data and location data obtained by analyzing the site survey data to determine the multiple candidate paths corresponding to the wind farm collection line, it is possible to reduce reliance on human experience to determine multiple paths, thereby improving the efficiency of candidate path planning and the accuracy of candidate path planning. According to the cost data and environmental data corresponding to the candidate paths, multiple candidate paths are planned to obtain the target path, which can improve the accuracy of the target path.

[0034] In order to enable those skilled in the art to better understand the path planning method for wind farm collector lines provided by the present disclosure, the above steps are described in detail with examples below.

[0035] For example, the environmental data may be natural environmental data and cultural element data of the wind farm, wherein the natural environmental data may include natural data of the site, construction data of the site, and public restriction data of the site, and the cultural element data may be architectural art element data of the site.

[0036] In the natural environment data, the natural data of the site may include topographic conditions, climatic conditions and geological conditions. Among them, the topographic conditions can be described through topographic maps, contour maps and corresponding topographic data and through a set of strict and clear expression languages. The climatic conditions can be the site wind conditions (wind direction, wind speed, air flow map, etc.), sunshine (sunshine hours, sunshine percentage, solar azimuth, etc.), temperature and precipitation. The geological conditions may include topography, geological structure, hydrogeology and earthquake conditions.

[0037] The construction data of the site may include regional location conditions, surrounding site conditions, internal construction conditions, and municipal facilities conditions. Among them, the regional location conditions may be the macro-environmental conditions in the area where the wind farm is located, and the surrounding site conditions may be the construction conditions of adjacent sites, special landscapes near the base, and cultural elements. Internal construction conditions may be the current conditions of buildings / structures, the conditions of site facilities (electricity, water facilities, etc.), and the current greening and vegetation. Municipal facilities conditions may be traffic conditions, water supply and drainage, and access points for electrical and telecommunication circuits.

[0038] The public restriction data of the site may include land use restrictions, land use nature, traffic control, density control, height control and population status. Among them, land use restrictions can be site boundaries (road red lines, land use red lines, building red lines, various lines), lengths of each side of the site and area data. The land use nature can be the positioning of the site use in urban planning. Traffic control can be the direction, size and parking conditions of the site's pedestrian and vehicle traffic. Density control can include building density and floor area ratio, and density control mainly represents the spatial distribution of blocks. Height control can include height restrictions and building floor control. Population status can be the number of existing residents in the site, the number of households and the population structure.

[0039] The data of architectural art elements may include site context analysis, cultural facade, site base analysis, site section, important buildings and landscape analysis in the site, sight line analysis in the site, volume analysis and local resident survey. Among them, site context analysis can be the overview of the surrounding and site buildings and cultural history, important historical events and historical elements. The cultural facade can be the more distinctive culture in the site. Site base analysis can be the plane base conversion analysis of buildings, vegetation, roads, and important water bodies. Site section can be the relationship between the existing buildings and landscape elements and terrain in the site. The analysis method in the analysis of important buildings and landscapes in the site can be a general architectural analysis method, such as block, light and shadow, material, space, function, traffic, etc. The sight line analysis in the site can be through the analysis of the best viewing angle of each building, and then a spatial model of a good sight corridor can be established. Volume analysis can study the volume relationship of buildings or important retained elements in the site, and find suitable building volume forms and insertion points. Local resident surveys can be for residents who usually live in the site.

[0040] The facility data of the site may be location data and layout data of each facility in the wind farm, wherein the facility may include a wind turbine generator set, a booster station, and a transformer substation, which is not specifically limited in the present disclosure.

[0041] The power transmission demand may be the required capacity that the user expects the path corresponding to the wind farm collection line to transmit in the wind farm to reach.

[0042] For example, environmental data can be analyzed to obtain environmental analysis data. Among them, when analyzing environmental data, the site analysis method can be used to analyze environmental data. Site analysis can be used to study the conditions of wind farms that need to be built and utilized, determine the essential attributes of wind farms and the relationships and contradictions between the various parts of the site, analyze the natural conditions, construction conditions and planning requirements of the wind farm where the building is located, and clarify the various factors affecting the site design. And after performing site analysis on environmental data, the wind farm can be evaluated from multiple factors such as topography, hydrogeology, climatic conditions and ecological sensitive areas. So that when the environmental analysis data is used for subsequent planning of candidate paths, it can be guaranteed that the candidate paths are environmentally friendly and sustainable paths for users. At the same time, it can also ensure that the collector lines operate in coordination with these facilities, thereby improving the overall operating efficiency of the wind farm.

[0043] The facility data of the site may be analyzed to obtain the location data of facilities in various directions in the wind farm, wherein the location data of facilities in various directions may include the location data of wind turbines and the location data of substations, which is not specifically limited in the embodiments of the present disclosure.

[0044] For example, multiple candidate paths corresponding to the collection line can be generated between the wind turbine and the substation based on the environmental analysis data, location data and power transmission requirements, and each candidate path can include parameters such as the number of wind turbines, the cross-section and length of the wire corresponding to the candidate path.

[0045] In a possible manner, generating a plurality of candidate paths corresponding to the collector line between the wind turbine generator set in the wind farm and the substation according to the environmental analysis data, the location data and the power transmission demand includes: Obtaining a constraint condition of the wind farm, wherein the constraint condition is used to characterize the area data of the candidate path corresponding to the collector line in the wind farm where the candidate path cannot be set; Converting the constraint conditions and the environmental analysis data into spatial layers and / or attribute data in a geographic information system; The location data, the power transmission demand, and the spatial layer and / or attribute data are analyzed and processed through the grid analysis function in the geographic information system to generate multiple candidate paths corresponding to the collection line between the wind turbine generator set in the wind farm and the substation.

[0046] It should be understood that the constraint condition may be regional data where candidate paths cannot be set in the wind farm. For example, the constraint condition may be restricted areas such as cultivated land, forest land, and protected areas; areas with unfavorable construction conditions such as caves, rivers, and earthquake zones; areas with sensitive factors such as cultural relics and minerals; and unfavorable meteorological conditions such as low temperature, repeated ice areas, and high altitudes.

[0047] A geographic information system (GIS) can be used to capture, store, analyze and manage geographic spatial data. In this embodiment, the constraints and environmental analysis data can be imported into the GIS together, and the constraints and environmental analysis data can be converted into spatial layers and / or attribute data through the GIS. For example, the prohibited construction area in the constraint condition can be set as an inaccessible area. The spatial layer can be used to represent a two-dimensional or three-dimensional model of a wind farm, and the attribute data can be non-spatial information associated with the geographic elements in the spatial layer.

[0048] Then, the location data, power transmission requirements, and spatial layers and / or attribute data can be analyzed and processed through the network analysis function in the geographic information system, and multiple candidate paths corresponding to the collector line can be generated between the wind turbine and the substation. The starting point of each candidate path is the wind turbine and the end point is the substation.

[0049] Based on the location data, power transmission requirements and constraints, the geographic information system generates multiple candidate paths between the wind turbine generator set and the substation, thereby increasing the speed of data update in the geographic information system. Compared with the planning of candidate paths corresponding to the collector line by relevant personnel based on the topographic map and the planning of paths by drones, the planning efficiency can be improved, and the accuracy of the candidate paths can be improved. At the same time, when multiple candidate paths are used to determine the target path in the future, the optimal line direction and tower position of the target path can be improved, thereby improving the safety and reliability of the path.

[0050] For example, in each candidate path, the candidate path has corresponding environmental data and cost data, and the environmental data of the candidate path can be electromagnetic environment data, noise environment data, ecological environment data, land resource data, water environment data, etc. Among them, the electromagnetic environment data can be the power frequency electric field and power frequency magnetic field generated by the candidate path during operation. The noise environment data can be the audible noise that may be generated by the candidate path during operation, such as the vibration of the wire in the wind, corona discharge, etc., and the noise generated by construction machinery and transportation vehicles during the construction of the candidate path. The ecological environment data can be the data such as vegetation destruction, topography changes, and wildlife habitats affected by construction activities during the construction of the candidate path. The land resource data can be the line corridor, substation construction land, etc. when constructing the candidate path. The water environment data can be the construction wastewater that may be generated when constructing the candidate path, such as foundation pit drainage, equipment cleaning water, etc.

[0051] The cost data can be determined based on the construction cost data, maintenance cost data and wind farm operation efficiency. Then, multiple candidate paths can be planned based on the environmental data and cost data to obtain the target path.

[0052] By planning multiple candidate paths through the environmental data and cost data and obtaining the target path, the negative impact of wind farm construction on the environment can be reduced, thereby improving the sustainable development capacity of the wind farm. At the same time, it can also provide comprehensive data support and scientific analysis methods, thereby improving the determination of the target path.

[0053] In a possible manner, performing path planning on the multiple candidate paths according to the environment data and the cost data to obtain a target path includes: Compare the cost data of each candidate path with a preset cost threshold, and determine a first number of candidate paths whose cost data is less than the preset cost threshold; The target path is determined according to the environmental data of each candidate path in the first number of candidate paths and a preset environmental assessment condition.

[0054] It should be understood that the preset cost threshold may be the minimum cost value that the user expects to achieve. When the cost data of a candidate path is less than the preset cost threshold, it may represent that the candidate path at this time is the candidate path expected by the user, and all candidate paths with cost data less than the preset cost threshold may be determined as the first number of candidate paths.

[0055] In the first number of candidate paths, the target path can be determined according to the golden data of each candidate path and the preset environmental evaluation condition, wherein the preset environmental evaluation condition can be the environmental benefit that the user expects to achieve in the process of constructing the candidate path.

[0056] Determining the target path from multiple candidate paths based on cost data and environmental data can comprehensively consider various constraints of the wind farm, thereby avoiding the target path crossing rugged terrain or areas prone to natural disasters, and achieving a balance between economy and feasibility when building a wind farm. At the same time, it can also improve the safety of wind power and avoid geological disasters in wind farms. At the same time, it can also reduce the length of the candidate path and reduce the loss of the candidate path, thereby improving the transmission efficiency of the candidate path.

[0057] In a possible manner, performing path planning on the multiple candidate paths according to the environment data and the cost data to obtain a target path includes: Comparing the cost data of each candidate path with a preset cost threshold, and when the cost data of each candidate path is greater than the preset cost threshold, adjusting at least one of the path direction of each candidate path, the facilities connected by the path, and the surrounding environment of the path in response to the user, until a second number of candidate paths with the cost data less than the preset cost threshold exist among the plurality of candidate paths; The target path is determined according to the environmental data of each candidate path in the second number of candidate paths and a preset environmental assessment condition.

[0058] It should be understood that when the cost data corresponding to each candidate path is less than the preset cost threshold, it may mean that there is no candidate path to continue the environmental assessment at this time. At this time, the user can adjust the path direction on the candidate path, the facilities connected by the path, and the environment around the path, so that there are a second number of candidate paths less than the preset cost threshold among the multiple candidate paths. The facilities connected by the path can be equipment such as poles, wind turbines, etc. The path direction can be the direction in which the path is laid. Then, among the second number of candidate paths, the target path is determined based on the environmental data of each candidate path and the preset environmental assessment conditions.

[0059] Determining the target path from multiple candidate paths based on cost data and environmental data can comprehensively consider various constraints of the wind farm, thereby avoiding the target path crossing rugged terrain or areas prone to natural disasters, and achieving a balance between economy and feasibility when building a wind farm. At the same time, it can also improve the safety of wind power and avoid geological disasters in wind farms. At the same time, it can also reduce the length of the candidate path and reduce the loss of the candidate path, thereby improving the transmission efficiency of the candidate path.

[0060] In a possible manner, the path planning method further includes: In response to an import operation on the target path in the simulation software, determining the target sub-candidate path model corresponding to the import operation; In response to a user's selection operation on a path direction, a tower type, and a conductor specification in the target sub-candidate path model, determining the target path model corresponding to the selection operation; In response to the user's evaluation operation on the target path model, when the evaluation operation shows that the power data corresponding to the target path meets the power transmission demand, the simulation is ended.

[0061] It should be understood that after determining the target path, in order to enable the target path to meet the power transmission requirements during the actual construction process, the path direction, tower type and conductor specifications required for the target path can be set in the simulation software platform.

[0062] Then, the target path can be simulated in the simulation software. First, the target can be imported into the simulation software, and the target sub-candidate path model can be obtained in the simulation software. Then, based on the target sub-candidate path model, the path direction, tower type and conductor specification can be selected to obtain the target path model, and then the target path model can be evaluated. When the evaluation result shows that the power data corresponding to the target path does not meet the power transmission demand, the path direction, tower type and conductor specification are adjusted until the power data corresponding to the target path meets the power transmission demand.

[0063] The simulation software may be any one of the overhead transmission line software, the transmission line digital platform and Daoheng software, and this embodiment does not make any specific limitation on this.
