[0002] At present, my country's power grid projects are in a stage of rapid development. In the early stage of power grid construction, transmission channel planning is particularly important. Power grid projects have the characteristics of long lines, large spans, and tight construction periods. When planning transmission channels, it is necessary to fully understand the conditions of the areas involved in the transmission channels, such as scenic spots, administrative planning, mining areas, and landforms.

[0003] At present, when planning a transmission channel, it is necessary to first collect relevant information, and then design and plan the transmission channel path based on the relevant information. For the path of the preliminary designed transmission channel, it is necessary to gradually compare it with the relevant information to find obstacles that affect the construction of the transmission channel, and then optimize the path of the transmission channel. However, most of the current relevant information is textual information, which is scattered and cumbersome, which results in low efficiency in power grid construction. In addition, when optimizing the design of the transmission channel, it is impossible to intuitively see the positional relationship between the planned path and the features in the area.

[0027] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Embodiment 1

[0029] like Figure 1 As shown, this embodiment provides a path optimization method for a transmission channel, including: obtaining preliminary path information, the preliminary path information is information describing a preliminary path for a transmission channel to be planned; based on the preliminary path information and a preset channel database, generating a path analysis diagram, the channel database stores information describing obstacle areas, each obstacle area represents an area that affects the construction of the transmission channel, and the path analysis diagram is a map marked with the preliminary path and the obstacle areas passed by the preliminary path; based on the path analysis diagram, generating a path optimization recommendation plan for the transmission channel to be planned.

[0030] The preliminary selected path is the path of the transmission channel to be planned, which is preliminarily designed by relevant personnel based on planning requirements, regional conditions, etc. The preliminary selected path information can be presented in the form of text, image, or a combination of text and image. The preliminary selected path information is used to describe the geographical location of the preliminary selected path, etc.

[0031] This method stores and manages information about areas that affect the construction of power transmission channels through a channel database. When optimizing the path of a power transmission channel, the preliminary designed path is matched with the channel database to determine the obstacle area that the preliminary path passes through. Based on this, a path analysis diagram is generated, and a path optimization suggestion is provided. This method can intuitively display the positional relationship between the preliminary path and the obstacle area that the preliminary path passes through through a path analysis diagram, and generate a path optimization suggestion to provide an optimization reference for relevant personnel.

[0032] Optionally, in an embodiment, the obstacle area includes an avoidance area and a clearing area, the avoidance area represents an area where construction of a power transmission channel is not allowed, and the clearing area represents an area where construction of a power transmission channel is allowed and channel clearing processing is required.

[0033] Optionally, in an embodiment, the channel database is constructed in the following manner: obtaining initial information, the initial information being information describing features within a preset area; obtaining avoidance area information and clearing area information from the initial information, respectively, the avoidance area information being information describing features within the preset area that belong to the avoidance area, and the clearing area information being information describing features within the preset area that belong to the clearing area; and constructing the channel database based on the avoidance area information and the clearing area information.

[0034] The sources of initial information mainly include previous power grid line engineering data and national basic geographic data. In addition, for the paths of built power line projects, the final survey path coordinates or path vector data are collected as initial information.

[0035] Before building the channel database, the collected initial information needs to be summarized, classified, checked for duplicates, and other processing, for example: data on the same geographical location are summarized together, and information such as the time period in which they are located is analyzed. Due to the large time span of previous projects, the different order, and the wide geographical distribution, the data will overlap. Therefore, it is necessary to screen and organize the information of the same geographical location, eliminate duplicate data and useless data, and retain the data corresponding to the latest time period for related data. The collected initial information is sorted and classified to facilitate the construction of a large channel database and provide data support for the subsequent application of power engineering.

[0036] In the process of sorting out the initial information, it is also necessary to mark the type, so as to facilitate the subsequent division of the avoidance area information and the cleanup area information by identifying the type. In this embodiment, the types of initial information include three categories: obstacle information, cross-over information and basic geographic information. Specifically, the obstacle information includes the following types: ecological category: protected areas, scenic areas, public welfare forests, ancient sites, etc. (reservoirs, planting bases, orchards, geothermal, beacon towers); mineral category: various mining areas (preliminary investigation areas, preliminary investigation areas, census areas, detailed investigation areas, mining areas, well fields, coal fields, gas fields); planning agreement category: planning areas, agreement areas, etc. (urban planning areas, township planning areas, military areas, basic farmland, explosives depots); industrial category: industry, factories (fields, enterprises, power plants, wind farms, industrial parks, development zones, science and technology parks, fireworks and firecrackers); other categories (new rural areas, radars, communication towers, substations, gas stations, etc.).

[0037] Crossing information includes the following types: ultra-high voltage power lines (±1100kV, 1000kV, ±800kV); other levels of power lines (750kV, 660kV, 500kV, ±500kV, 400kV, 330kV, 220kV, 110kV, 35kV); underground pipelines (oil pipelines, natural gas pipelines, optical cables, water pipes, etc.).

[0038] Basic geographic information includes the following types: administrative divisions (provincial boundaries, municipal boundaries, county boundaries, provincial capitals, prefecture-level cities, county names, towns, villages, etc.); transportation roads (railways, expressways, national roads, provincial roads, county roads, etc.); thematic information (ice areas, polluted areas, earthquake intensity, geology, vegetation classification, etc.).

[0039] In the process of collating the initial information, the specific types of division can be set according to actual needs to provide a data basis for the construction of the channel database.

[0040] For obtaining the avoidance area information and the cleanup area information from the initial information, specifically: pre-set the types of avoidance areas and cleanup areas. For example, if the types of avoidance areas include minerals, the information marked as minerals in the initial information preprocessing process is classified as avoidance area information. Based on this, the initial information is screened and classified to obtain the avoidance area information and the cleanup area information.

[0041] In the early planning stage of power grid projects, the construction of the channel database provides data support for improving the feasibility of the transmission channel. The channel database can not only be used in the path optimization stage of the transmission channel, but also provide data reference for the early design and planning of the transmission channel, reducing the field survey work in the early stage.

[0042] Optionally, in an embodiment, generating a path analysis diagram based on the preliminary path information and a preset channel database includes: generating first information and second information according to the preliminary path information and the preset channel database, respectively, the first information being information describing an avoidance area passed by the preliminary path, and the second information being information describing a clearing area passed by the preliminary path; generating the path analysis diagram according to the preliminary path information, the first information and the second information.

[0043] Optionally, in an embodiment, the path analysis diagram is generated according to the preliminary path information, the first information and the second information, including: generating an initial path analysis diagram according to the preliminary path information, the first information and the second information; determining an avoidance path segment according to the initial path analysis diagram, the avoidance path segment representing a section of the preliminary path passing through an avoidance area; generating third information according to the avoidance path segment and the channel database, the third information being information describing an obstacle area contained in an area formed by extending a preset first distance from the avoidance path segment as the center line to both sides of the avoidance path segment; and updating the initial path analysis diagram according to the third information to generate the path analysis diagram.

[0044] By expanding the area where the avoidance path segment is located, the avoidance area and the clearing area in the expanded area are identified to generate the third information. Based on the third information, the initial path analysis diagram is updated, so that the area near the avoidance path segment can be intuitively viewed in the path analysis diagram, which is convenient for relevant personnel to optimize and adjust the avoidance path segment. In the path analysis diagram, the avoidance area and the clearing area can be marked with different colors or symbols to distinguish between the avoidance area and the clearing area.

[0045] The proposed route optimization solution can be presented in text form, or the optimized route can be generated based on the route analysis diagram. The following is an explanation with specific examples:

[0046] Optimization case 1: Figure 2 As shown in the figure, the preliminary route passes through the Lexiu Tao River Scenic Area and needs to be avoided. The adjustment plan given by this method is: adjust the line to the north to avoid the Lexiu Tao River Scenic Area, while taking into account the tower positions along the line to facilitate construction.

[0047] Optimization case 2: Figure 3 As shown in the figure, when the primary route passes through Linjiang Township, Dangchang County, it needs to avoid the Aquatic Biological Reserve Experimental Area of ​​Dangchang County to protect the local ecological environment. The adjustment plan given by this method is: adjust the route to avoid the aquatic biological reserve.

[0048] Optimization case three: Figure 4 As shown in the figure, the initial route is in Yang County and crosses the experimental area of ​​the Crested Ibis Reserve, so it is difficult to obtain an agreement. The adjustment plan given by this method is to adjust the route to avoid the experimental area of ​​the Crested Ibis Reserve.

[0049] In summary, the construction of the channel database provides detailed and reliable channel data support for subsequent engineering applications, making it easier to grasp specific situations such as obstacles and cross-overs. In addition, the path analysis diagram can intuitively display the positional relationship between the preliminary path and the obstacle area passed by the preliminary path, and generate a path optimization suggestion plan to provide optimization reference for relevant personnel. This method greatly improves the engineering work efficiency and the accuracy of path planning.
