[0002] Power lines are the lines used to transmit electrical energy between power plants, substations, and power users. They are a vital component of the power supply system, responsible for the transmission and distribution of electrical energy. Due to the complex nature of the nodes in power lines, power line design requires surveying each node or path to provide a reference for engineering design and economic considerations.

[0003] However, traditional power line surveys typically follow uniform engineering standards, surveying each node within the power line, including topographic surveys of factories, mines, villages, lakes, and more.

[0040] In order to better understand the purpose, technical solutions and technical effects of the present invention, the present invention is further explained below with reference to the accompanying drawings and embodiments. It is also stated that the embodiments described below are only used to illustrate the present invention and are not intended to limit the present invention.

[0041] An embodiment of the present invention provides a power line survey and design method.

[0042] Figure 1A flow chart of a power line survey and design method according to an embodiment of the present invention is shown in FIG. Figure 1 As shown, a power line survey and design method according to an embodiment includes steps S100 to S103:

[0043] S100, configuring a virtual survey node for each separate survey area;

[0044] S101, assigning weight to any virtual survey node according to its survey task;

[0045] S102, weighting the power transmission lines between any virtual survey node and adjacent virtual survey nodes according to the power transmission resources between any virtual survey node and adjacent virtual survey nodes;

[0046] S103, establishing a power transmission network according to the weighting result; wherein the power transmission network is used for power line survey and design.

[0047] The geographical areas through which the power lines pass are determined, and the geographical areas are divided into survey areas based on geographical factors or economic considerations. In one embodiment, the survey areas include administrative areas or terrain classification areas. The terrain classification areas include mountainous areas, plains, deserts, or wetlands.

[0048] When planning power lines, virtual survey nodes are configured for each separate survey area according to the target planning, and field surveys are conducted on each virtual survey node to execute survey tasks and obtain survey parameters.

[0049] Any virtual survey node is weighted according to its survey task.

[0050] In one embodiment, Figure 2 A flow chart of a power line survey and design method according to another embodiment of the present invention is shown in FIG. Figure 2 As shown, the process of assigning weights to any virtual survey node according to the survey task of any virtual survey node in step S101 includes steps S200 and S201:

[0051] S200, obtaining survey parameters according to a survey task of any virtual survey node;

[0052] S201: Assign weights to any virtual survey node according to survey parameters.

[0053] In one embodiment, the survey parameters include meteorological parameters, geological parameters, topographic parameters, or economic parameters. Data screening is performed based on the determined survey parameters. The survey parameters can be weighted based on subjective weighting to obtain node weights.

[0054] In one embodiment, each survey parameter can be divided into discrete data intervals based on a discrete interval data processing method, and weights can be determined based on the intervals of the survey parameters. Through discrete interval data processing, the influence of subjective factors is eliminated and the weight standards for each survey area are unified.

[0055] In power line planning, a power line is pre-established between any virtual survey node and an adjacent virtual survey node. During power line transmission, data is transmitted from any virtual survey node to an adjacent virtual survey node. Furthermore, a weight is assigned to the power transmission line between any virtual survey node and an adjacent virtual survey node to obtain a power transmission line weight.

[0056] In one embodiment, Figure 2 As shown, the process of assigning weights to power transmission lines between any virtual survey node and adjacent virtual survey nodes according to power transmission resources between any virtual survey node and adjacent virtual survey nodes in step S102 includes step S202:

[0057] S202 : weighting the power transmission line between any virtual survey node and an adjacent virtual survey node according to the power transmission duration between any virtual survey node and an adjacent virtual survey node.

[0058] The power transmission duration is affected by the type of survey node. Among them, the survey node includes a power plant, a substation, an energy storage power station or an electricity user. The power transmission duration includes the power transmission duration between any virtual survey node and an adjacent virtual survey node. When there is an energy storage power station at the survey node, the energy storage power station communicates with other nodes to allocate power; the time spent by the energy storage power station when storing energy is the energy storage duration. In one embodiment, the process of weighting the power transmission line between any virtual survey node and the adjacent virtual survey node according to the power transmission duration between any virtual survey node and the adjacent virtual survey node in step S202 is as follows:

[0059]

[0060] in, represents the weight of the power transmission line from any virtual survey node i to the adjacent virtual survey node j, represents the power transmission time from any virtual survey node i to the adjacent virtual survey node j, W i represents the power loss of any virtual survey node i, W j represents the power loss of the adjacent virtual survey node j, C i represents the energy storage capacity of any virtual survey node i, f(E efficiency ) represents the mapping function between the energy storage capacity and energy consumption rate of any virtual survey node i, represents the communication duration from any virtual survey node i to the adjacent virtual survey node j, represents the storage time of the electric energy transmitted from any virtual survey node i to the adjacent virtual survey node j in the adjacent virtual survey node j, P i,u It represents the physical movement duration from any virtual survey node i to the adjacent virtual survey node j.

[0061] The physical movement duration from any virtual survey node i to the adjacent virtual survey node j can be adjusted to the appropriate physical movement duration by setting the physical movement speed according to the driving time and operation time of the survey area.

[0062] Based on this, a power transmission network is established according to multiple virtual survey nodes and multiple weighted results, and the power transmission network is visualized by weights.

[0063] In one embodiment, Figure 2 As shown, the process of establishing the power transmission network according to the weighting result in step S103 includes steps S203 to S205:

[0064] S203, establishing a node weight set according to the weighting result of any virtual survey node;

[0065] S204, establishing a line weight set according to the weighting result of the power transmission line;

[0066] S205: Establishing a power transmission network according to the virtual survey nodes, the node weight set, and the line weight set.

[0067] Based on this, Figure 2 As shown, the power line survey and design method of another embodiment further includes step S206:

[0068] S206 , determining a transmission path including all virtual survey nodes and having the largest weight according to the power transmission network.

[0069] Figure 3 is a schematic diagram of the power transmission network, such as Figure 3 As shown in the visualization of the power transmission network, each virtual survey node has a corresponding node weight, and each power transmission line has a corresponding line weight. Between two non-adjacent virtual survey nodes over a long distance, the total weight is the sum of the node weights and line weights that form the path.

[0070] The transmission path is determined based on the maximum value of the sum of weights.

[0071] In any of the above-described embodiments, after configuring virtual survey nodes for each discrete survey area, the power line survey and design method assigns weights to each virtual survey node based on its survey task. Furthermore, based on the power transmission resources between each virtual survey node and its adjacent virtual survey nodes, the power transmission lines between each virtual survey node and its adjacent virtual survey nodes are weighted. Finally, based on the weighted results, a power transmission network for power line survey and design is established. This further enhances the reference value of power line survey and design through digital means, based on survey tasks and power transmission resources, providing an effective reference for power line planning.

Furthermore, weights the power transmission lines between each virtual survey node and its adjacent virtual survey nodes based on their power transmission resources.
