[0002] At present, in order to meet the demand of reducing carbon emissions, building a new power system with new energy as the main body is one of the main ways to achieve carbon peak and carbon neutrality. With the continuous and rapid development of new energy technologies such as wind power generation and photovoltaic power generation, the development and construction quality and consumption and utilization of new power systems have been significantly improved. Therefore, on the energy supply side, further increasing the proportion of new energy such as wind power generation and photovoltaic power generation is the main trend in the future.

[0003] However, in the construction of large-scale wind or photovoltaic power generation bases, land resources are consumed greatly. For example, in addition to roof resources, the high-voltage transmission lines of the new power system are long, and the high-voltage transmission corridors will occupy a large area, thus wasting a lot of land resources. In addition, the layout cost of photovoltaic power stations in related technologies is high, and the layout process is relatively cumbersome. Summary of the invention

[0053] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0054] It should be noted that with the development of digital technology, three-dimensional digital design work can now be carried out in the design of transmission lines. The three-dimensional digital design of transmission lines is based on the digital earth. On the basis of high-resolution image data, it integrates and manages basic geographic data and power grid thematic data, integrates three-dimensional line selection, two- and three-dimensional synchronous ranking, and real-time verification functions, integrates electrical, structural and other unit design results, provides collaborative design in three-dimensional visualization scenes, realizes the digitalization of transmission line design, three-dimensional visualization and digital management of finished designs, and supports seamless connection with various professional application software. Based on this, the present application can make full use of the three-dimensional digitalization results of transmission lines, such as digital information of overhead transmission lines, surrounding landforms and geographic information data, to arrange photovoltaic power stations, thereby improving the design efficiency of photovoltaic power stations and reducing design costs.

[0055] The following describes a photovoltaic power station layout method and system based on a three-dimensional design result of a power transmission line according to an embodiment of the present application with reference to the accompanying drawings.

[0056] Figure 1 A schematic diagram of a process of arranging a photovoltaic power station based on a three-dimensional design result of a transmission line proposed in an embodiment of the present application is shown in FIG. Figure 1 As shown, the system comprises the following steps:

[0057] S1: Obtain information from a preset power grid information model GIM file of a transmission line, and select an initial transmission line section for arranging a photovoltaic power station based on the information, the information including geographic information, terrain information and elevation information of the transmission line corridor, and sag information of the transmission line.

[0058] Among them, the Grid Information Model (GIM) is a technical standard for the three-dimensional design of power transmission and transformation projects in the field of three-dimensional power design. After the three-dimensional design of the transmission line is completed in advance, the three-dimensional digital GIM file of the transmission line can be generated. The GIM file of the transmission line includes various types of data related to the transmission line, such as digital information of the transmission line, topographic information around the transmission line, and geographic information. This application can extract relevant information from the GIM file as needed to arrange the photovoltaic power station, that is, design the photovoltaic power station based on the existing three-dimensional digital results of the transmission line.

[0059] It can be understood that in actual applications, the conductor connected between two towers is a curve with a certain curvature. The sag of the transmission line refers to the distance between the connection point between the conductor and the tower and the inflection point of the curve. In the embodiment of the present application, the conductor can be regarded as a sag line.

[0060] Specifically, first obtain the geographic information, terrain information and elevation information of the transmission line corridor in the GIM file of the existing transmission line, as well as the sag information of the transmission line. The geographic information of the transmission line corridor can include the specific geographical location of any section of the transmission line, such as the longitude and latitude of County B in City A and the geographical environment of different sections. The terrain information refers to the shape and landform information of the surrounding objects of the transmission line corridor. Then, based on the acquired information, the transmission line section suitable for arranging the photovoltaic power station is preliminarily selected in the entire transmission line. After multiple judgments are made to determine that the initial transmission line section meets the various conditions for arranging the photovoltaic power station, the photovoltaic power station can be arranged in the area below the transmission line section.

[0061] In one embodiment of the present application, screening can be performed based on the acquired geographic information and terrain information. For example, sections that are not suitable for arranging photovoltaic power stations can be screened out based on whether there are obstacles in the geographical environment where different sections in the geographic information are located. For example, sections where there are buildings such as ditches under the transmission line can be excluded. Transmission line sections located in steeper mountainous areas can also be excluded based on terrain information. The initial transmission line sections that are suitable for arranging photovoltaic power stations based on the acquired information, such as the geographical environment and terrain, are screened out to facilitate further judgment of the initial transmission line sections. The specific method for preliminary screening is not limited here.

[0062] S2: Calculate the slope and slope direction of the initial transmission line section according to the terrain information and elevation information, and determine whether the initial transmission line section meets the terrain conditions for arranging the photovoltaic power station according to the slope and slope direction. If not, return to execute S1.

[0063] It should be noted that when the slope of the initial transmission line section is too high, it may make it impossible to arrange the photovoltaic modules stably and conveniently. When the slope of the initial transmission line section does not match the layout of the photovoltaic modules, it may block the photovoltaic modules, resulting in excessive shadow areas that affect the power generation efficiency of the photovoltaic power station.

[0064] Therefore, in one embodiment of the present application, the slope and slope direction of the initial transmission line section can be calculated based on the terrain information and elevation information obtained from the GIM file. In the specific calculation, the slope can be calculated based on the elevation difference at different positions, and then the direction of the slope can be determined based on the terrain and slope of the slope. Then, it is determined whether the slope of the initial transmission line section exceeds the preset slope threshold, and combined with the layout direction of the photovoltaic modules, it is determined whether the slope direction of the initial transmission line section is suitable for arranging the photovoltaic modules.

[0065] For example, the preset slope threshold is 1%. If the calculated slope of the initial transmission line section is greater than 1%, or, when the photovoltaic panels are expected to be placed facing due south, if the slope is higher in the south and lower in the north, then it is judged that the initially screened initial transmission line section does not meet the terrain conditions for the layout of the photovoltaic power station.

[0066] Furthermore, if it is determined that the current initial transmission line section does not meet the terrain conditions for arranging the photovoltaic power station, the section is excluded and the process returns to step S1 to reselect the initial transmission line section for arranging the photovoltaic power station in the manner described in step S1.

[0067] It is understandable that due to the long length of the transmission line, which can reach millions of kilometers, the area of ​​the high-voltage transmission corridor is also relatively large, and the available land resources are sufficient. Therefore, in the embodiment of the present application, when it is judged under different conditions that the initially screened transmission line section is not suitable for the layout of the photovoltaic power station, other transmission line sections can be re-screened for judgment.

[0068] S3: Determine whether the light radiation intensity of the initial transmission line section meets the light resource conditions. If not, return to execute S1.

[0069] Specifically, since the power generation of a photovoltaic power station is directly related to whether the light resources in the area are sufficient, in order to meet the construction requirements such as the power generation of the photovoltaic power station, the light radiation intensity of the initial transmission line section can be obtained through different methods, and then it can be determined whether the light radiation intensity of the section meets the radiation intensity requirements specified in the light resource conditions.

[0070] As an example, the light radiation intensity of the geographical location of the initial transmission line section can be obtained in a meteorological database application, for example, in meteonorm, based on the geographical location of the initial transmission line section, and then compared to see whether the light radiation intensity of the initial transmission line section is greater than a preset radiation intensity threshold. If so, it is determined whether the light resource conditions for the site selection of the photovoltaic power station are met. If less than the radiation intensity threshold, the section is excluded, and the process returns to the above step S1, and the initial transmission line section for arranging the photovoltaic power station is reselected in the manner described in step S1.

[0071] S4: Calculate the distance between two adjacent photovoltaic modules and the inclination angle of the photovoltaic modules according to the geographic information and the height of the photovoltaic modules to be arranged.

[0072] The geographical information may be the longitude and latitude of the initial transmission line section, and the height of the photovoltaic module to be arranged is the vertical distance between the top of the photovoltaic module and the ground, that is, Figure 2 h shown in . The spacing between two adjacent PV modules is the horizontal distance between two points at the same position in the two adjacent PV modules, that is, Figure 2 The inclination angle of the photovoltaic module is the angle between the photovoltaic module and the horizontal plane, that is, Figure 2 As shown in

[0073] In one embodiment of the present application, the height h of the photovoltaic module can be determined according to the actual layout requirements of the photovoltaic module on site, and the longitude and latitude information of the current initial transmission line section can be obtained from the GIM file. Then, the spacing between two adjacent photovoltaic modules is calculated by the following formula:

[0074]

[0075] Among them, d is the distance between two adjacent photovoltaic modules, h is the height of the photovoltaic module, and ω is the latitude of the initial transmission line section. And the inclination angle of the photovoltaic module is calculated by the following formula:

[0076]

[0077] in, is the inclination angle of the PV panel, and the meaning of ω is the same as in the above formula.

[0078] S5: According to the setting information of the transmission line corridor and the spacing of the photovoltaic modules, the photovoltaic module array and the distribution components are simulated and arranged in the photovoltaic system design application.

[0079] Among them, the setting information of the transmission line corridor includes the shape, direction, distance between two adjacent towers and width of the transmission line corridor, etc., and the layout information of the transmission line corridor at the actual work site. Since the transmission line has been pre-arranged, the above setting information of the transmission corridor in the initial transmission line section can be directly obtained from the GIM file of the transmission line. The spacing of photovoltaic modules can be determined according to the layout requirements of photovoltaic modules.

[0080] In one embodiment of the present application, in a photovoltaic system design application, for example, in Pvsyst, the layout of photovoltaic components can be determined based on the setting information of the transmission line corridor and the spacing of the photovoltaic components, and the layout of the photovoltaic component array and the distribution components of the photovoltaic array can be simulated in the plan view of the application.

[0081] For example, Figure 3 As shown, the number of rows of photovoltaic modules arranged in the corridor is determined to be 2 according to the width of the transmission line corridor and the size of the photovoltaic modules 10 to be arranged, and the number of photovoltaic modules 10 in each row between two adjacent towers is determined according to the distance between tower 1 and tower 2 and the size of the photovoltaic modules 10. The shape and direction of the transmission line corridor can also be used, for example, Figure 3 The arrangement direction of the photovoltaic components 10 in the plane is determined from southwest to northeast. After the photovoltaic component array is arranged, the corresponding power distribution component is arranged for each photovoltaic component 10.

[0082] Therefore, the actual layout scenario was simulated and the photovoltaic power station was simulated and arranged in the two-dimensional plan view of the photovoltaic system design application.

[0083] S6: Combine the model of the transmission line corridor to simulate the operation of the photovoltaic power station model under shadow conditions, and judge whether the shadow shielding rate of the initial transmission line section meets the construction requirements based on the simulation results. If not, return to execute S1.

[0084] The model of the transmission line corridor includes a three-dimensional model of a tower and a three-dimensional model of a conductor, and the photovoltaic power station model includes a photovoltaic array model and a distribution component model arranged in step S5.

[0085] In an embodiment of the present application, a three-dimensional model of the transmission line corridor within the initial transmission line section is imported into a photovoltaic system design application, such as Figure 4 As shown, the photovoltaic power station model is arranged below the model of the transmission line corridor in the manner of step S5, and the actual working scene of the photovoltaic power station is simulated, that is, the operation process of the photovoltaic power station under the shadow caused by the occlusion of the three-dimensional transmission line corridor model is simulated, and then according to the simulation operation results, it is determined whether the shadow occlusion rate of the area is too high if the photovoltaic power station is arranged in the initial transmission line section.

[0086] It is understandable that when the shadow obstruction rate is too high, the output power and other parameters of the photovoltaic power station are low and cannot meet the expected output requirements for building a photovoltaic power station. In this application, the shadow obstruction rate of the initial transmission line section can be judged based on the simulation results of the overall output of the photovoltaic power station system running under the shadow to meet the requirements for the construction of the photovoltaic power station.

[0087] In one embodiment of the present application, judging whether the shadow obstruction rate of the initial transmission line section meets the construction requirements based on the simulation results includes the following steps: first, obtaining different types of simulation results of the photovoltaic power station model within a preset time period, and the simulation results may include: the relationship between daily input energy and output energy, system efficiency, system output power distribution, and the corresponding relationship between effective irradiance and array temperature, etc.; then judging whether there is any type of simulation result that does not meet the corresponding operating requirements. If any simulation result does not meet the corresponding requirements, it is determined that the shadow obstruction rate of the initial transmission line section does not meet the construction requirements of the photovoltaic power station.

[0088] Specifically, the preset time period can be one year, so as to fully reflect the changes in the simulation results of the photovoltaic power station output. Figure 5 As shown in the figure, the daily input energy refers to the total radiation of the lighting surface of the photovoltaic power station, and the unit is kWh / m 2 , the output energy is the grid-connected power of the photovoltaic power station, the unit is kWh, the grid-connected power output of the photovoltaic power station under the corresponding total radiation of the lighting surface is counted every day, and the relationship between the daily input energy and output energy of the photovoltaic power station in one year is summarized. Figure 6 As shown in the figure, the system efficiency (PR) of the photovoltaic power station is counted every month, and the system efficiency of the photovoltaic power station is summarized every month in a year. Figure 7 As shown in the figure, the grid-connected power output of the photovoltaic power station is counted every day, and the partition curve of the system output power of the photovoltaic power station within a year is obtained through curve fitting. Figure 8As shown in the figure, the effective irradiance can be the effective total radiation after correcting the shading and IAM (Incidence Angle Modifier) ​​loss, the array temperature can be the average temperature of the photovoltaic module array during operation, and the array temperature corresponding to the effective irradiance of the photovoltaic power station is counted daily, and the information of the effective irradiance and array temperature of the photovoltaic power station every day within one year is summarized.

[0089] In the embodiment of the present application, the target range corresponding to the operating parameters of each photovoltaic power station model is pre-set. If the simulated result is not within the corresponding target range, it is determined that the simulation result does not meet the corresponding requirement, and the shadow blocking rate of the initial transmission line section does not meet the requirements for photovoltaic power station construction. For example, the minimum threshold of the photovoltaic power station system efficiency is preset. If the system efficiency of any month is lower than the minimum threshold, it is determined that the system efficiency of the photovoltaic power station model does not meet the operating requirements due to the shadow blocking. Therefore, the shadow blocking rate of the initial transmission line section does not meet the requirements for building a photovoltaic power station.

[0090] Furthermore, if it is determined that the shadow occlusion rate of the current initial transmission line section does not meet the construction requirements, the section is excluded and the process returns to step S1 to reselect the initial transmission line section for arranging the photovoltaic power station in the manner described in step S1.

[0091] S7: Determine whether the vertical distance between the top of the photovoltaic module and the conductor meets the safety distance condition. If not, return to execute S1.

[0092] It should be noted that due to the high voltage on the conductors in the transmission lines, it is necessary to ensure that the distance between the conductors and the photovoltaic modules is greater than a predetermined safety distance, which can be the minimum vertical distance between the conductors and the buildings specified in the relevant technology.

[0093] In order to more clearly illustrate the specific implementation process of determining whether the vertical distance between the top of the photovoltaic module and the wire meets the safety distance condition, the following is a method for determining whether the vertical distance between the top of the photovoltaic module and the wire meets the safety distance condition proposed in this application. Fig. 9 As shown, the method includes:

[0094] S901, obtaining the distance between the conductor above each photovoltaic module and the ground.

[0095] Specifically, the distance between the conductor and the ground is h0, that is, the distance between the sag line above the photovoltaic module and the ground. In the embodiment of the present application, the distance between the sag line above each photovoltaic module and the ground can be calculated separately according to the sag information of the transmission line obtained in step S1.

[0096] S902, querying a mapping relationship between a preset nominal voltage and a minimum vertical distance to a building according to the nominal voltage on the conductor, and obtaining the minimum vertical distance between the conductor above each photovoltaic module and the building.

[0097] The mapping relationship between the nominal voltage and the minimum vertical distance from the building is shown in Table 1 below. The minimum vertical distance from the building corresponding to different voltages loaded on the conductor can be determined in advance according to relevant safety specifications.

[0098]

[0099] Table 1

[0100] Specifically, the nominal voltage of the conductor in the initial transmission line section is obtained from the GIM file of the transmission line, and then the above Table 1 is queried to determine the minimum vertical distance H between the conductor and the building required in the section.

[0101] S903, determining whether the minimum vertical distance between the wire above any photovoltaic module and the building and the sum of the heights of any photovoltaic module are less than the shortest distance between the wire above any photovoltaic module and the ground.

[0102] Specifically, the minimum vertical distance H between the conductor above any photovoltaic module and the building is added to the height h of the photovoltaic module determined in step S4, and compared with the shortest distance h0 between the conductor above the photovoltaic module and the ground to determine whether H+h≤h0 is satisfied. If not, it is determined that the vertical distance between the top of the photovoltaic module and the conductor does not meet the safety distance condition. Each photovoltaic module is judged in turn in the above manner to verify whether the vertical distance between the top of each photovoltaic module and the conductor meets the safety distance condition.

[0103] As an example, as shown in the following Table 2, it is checked whether the straight distance of each photovoltaic module between two towers meets the safety distance condition.

[0105] Table 2

[0106] As can be seen from Table 2, in this example, since each verification result is greater than zero, it can be determined that if a photovoltaic power station is set up in the current initial transmission line section, the vertical distance between the top of each photovoltaic module and the conductor meets the safety distance condition.

[0107] In one embodiment of the present application, after determining that the vertical distance between the top of the photovoltaic module and the wire does not meet the safety distance condition, the photovoltaic module that does not meet the safety distance condition can be adjusted. Specifically, the height h of the photovoltaic module that does not meet the safety distance condition is adjusted. The adjusted photovoltaic module can be one, or each module can be adjusted in turn when there are multiple photovoltaic modules. By reducing h, H+h≤h0 is satisfied.

[0108] It should be noted that, since in actual applications, there is a minimum value limit for the height h of the photovoltaic module, after adjusting the height of the photovoltaic module within the allowable adjustment range, it is determined again whether the vertical distance between the top of the adjusted photovoltaic module and the conductor meets the safety distance conditions. If the vertical distance between the top of the adjusted photovoltaic module and the conductor still does not meet the safety distance conditions, return to the above step S1 and reselect the initial transmission line section for arranging the photovoltaic power station in the manner described in step S1.

[0109] S8: Determine whether the electromagnetic environment of the initial transmission line section meets the safety induced voltage conditions. If not, return to execute S1. If yes, arrange the photovoltaic power station with the initial transmission line section as the target section.

[0110] Specifically, during the actual transmission of power through the transmission line, the conductor will generate an induced voltage. When the induced voltage is too large, it will cause harm to the surrounding workers. In the embodiment of the present application, the safe induced overvoltage of the human body can be used as the safe induced voltage to determine whether the induced voltage in the electromagnetic environment of the initial transmission line section is greater than the safe induced voltage.

[0111] As a possible implementation method, the electromagnetic calculation function of the transmission line three-dimensional design software can be used to calculate the induced voltage in the electromagnetic environment of the initial transmission line section, and the calculated induced voltage can be compared with the human body safety induced overvoltage of 24V. If it is greater than 24V, it is determined that the current electromagnetic environment does not meet the safety induced voltage conditions. Among them, the transmission line three-dimensional design software can calculate various parameters in the electromagnetic environment such as the maximum electric field strength on the surface of the conductor, the maximum electric field strength on the surface of the ground wire, the conductor corona initiation field strength and the maximum electric field strength on the ground. Since this application is to avoid danger to personnel working on the ground, in this example, the induced voltage on the ground is calculated based on the ground parameter information such as the maximum electric field strength on the ground, and then compared with the human body safety induced overvoltage.

[0112] Furthermore, if it is determined that the electromagnetic environment of the current initial transmission line area does not meet the safety induced voltage condition, the section is excluded, and the process returns to the above step S1, and the initial transmission line section for arranging the photovoltaic power station is reselected in the manner described in step S1. If it meets the conditions, the photovoltaic power station is arranged with the initial transmission line section as the final target section. In specific implementation, the photovoltaic modules can be arranged in the target section according to the setting parameters of the photovoltaic modules in space and the two-dimensional arrangement of the photovoltaic power station determined in the above embodiment.

[0113] Therefore, the present application automatically reads the information of the transmission line and performs multiple rounds of condition verification to determine the section suitable for arranging the photovoltaic power station and the layout method of the photovoltaic power station, thereby realizing the semi-automatic layout of the photovoltaic power station, improving the efficiency of the layout of the photovoltaic power station, and ensuring the economic benefits of the photovoltaic power station after layout.

[0114] In summary, the photovoltaic power station layout method based on the three-dimensional design results of the transmission line in the embodiment of the present application arranges the photovoltaic power station according to the three-dimensional design results of the transmission line, and arranges the photovoltaic power station in a suitable transmission line corridor channel area, which can make full use of the land area occupied by the transmission line and improve the utilization rate of land resources. In addition, the layout and design of the photovoltaic power station can be carried out by using the three-dimensional digitization results of the transmission line, and the geographic information and the data of the existing towers and wires of the transmission line can be directly extracted, which reduces the survey cost, improves the efficiency of obtaining data, and is conducive to the semi-automatic layout of the photovoltaic power station. The method also judges and selects whether the transmission line section is suitable for arranging the photovoltaic power station based on different conditions based on the data obtained from the three-dimensional data platform of the transmission line, and realizes the search for a suitable layout section according to the location of the transmission corridor, and can accurately arrange the arrangement of each component in the photovoltaic power station. Thereby improving the design efficiency of the photovoltaic power station, the applicability and accuracy of the layout of the power station, and reducing the design cost.

[0115] In order to more clearly describe the specific implementation process of the photovoltaic power station layout method based on the three-dimensional design results of the power transmission line of the present application, a specific embodiment is described in detail below. Fig.10 A schematic diagram of a specific photovoltaic power station layout method based on the three-dimensional design results of the transmission line proposed in the embodiment of the present application is shown in FIG. Fig.10 As shown, the method comprises the following steps:

[0116] Step S10, obtaining the geographical information, terrain and elevation information of the transmission line corridor in the transmission line GIM file, reading the arc-slope data of the transmission line, and preliminarily screening the transmission line section suitable for photovoltaic layout.

[0117] Step S20, calculate the slope and slope direction of the screening area, and determine whether the terrain of the selected area is suitable for arranging a photovoltaic power station. If so, execute step S30, if not, execute step S10.

[0118] In this step, the slope and slope direction of the area are calculated based on the terrain and elevation data to determine whether the terrain of the selected area is suitable for arranging a photovoltaic power station. If the slope is greater than 1%, or the slope direction is higher in the south and lower in the north, the area is considered unsuitable for arranging a power station, and the process returns to S10 to re-screen the arrangement area.

[0119] Step S30, preliminarily judging in meteonorm whether the light resource conditions of the selected area meet the requirements for the site selection of the photovoltaic power station, if yes, executing step S40, if not, executing step S10.

[0120] In this step, based on the read geographical location, it is preliminarily determined in meteonorm whether the light resource conditions in the area meet the requirements for the site selection of the photovoltaic power station. If the radiation intensity in the area does not meet the requirements, it returns to S10 to re-screen the photovoltaic layout area.

[0121] Step S40, calculating the photovoltaic panel spacing and photovoltaic panel inclination angle according to the geographical location of the selected area.

[0122] In this step, according to the geographical location, the spacing and inclination of the photovoltaic panels are calculated according to the following formula (1), and the angle between the photovoltaic panels and the horizontal plane is calculated according to the following formula (2).

[0123]

[0124]

[0125] Step S50, determining a layout plan according to the shape of the transmission corridor and the spacing between photovoltaic modules.

[0126] In this step, the PV arrays and distribution components are arranged in the plan view of Pvsyst according to the shape of the transmission corridor and the spacing between PV components.

[0127] Step S60, read the three-dimensional model of the tower and the conductor, and import it into PVsyst to calculate the shadow, and determine whether the shadow occlusion rate meets the project construction requirements. If so, execute step S70, if not, execute step S10.

[0128] In this step, the three-dimensional model of the tower and the conductor in the GIM file is read and imported into PVsyst for shadow simulation and calculation. If the shadow occlusion rate is too high and does not meet the project construction requirements, return to S10 for adjustment and re-screen the photovoltaic layout area.

[0129] In one embodiment of the present application, according to the direction of sunlight, the impact of the shadow of the north-south transmission corridor is much greater than that of the east-west corridor. Therefore, in this embodiment, it is possible to give priority to finding the east-west corridor to reduce the impact of the shadow and increase the success rate of screening out sections that meet the requirements.

[0130] Step S70, determining whether the distance between the photovoltaic module and the conductor meets the requirement.

[0131] In this step, check whether the distance between the top of each photovoltaic panel and the vertical distance of the wire meets the requirements. The distance between the upper arc vertical line of each photovoltaic panel and the ground is h0, and the minimum vertical distance from the building required by the preset specification is obtained as H, and it is determined whether H+h≤h0 is satisfied. If the vertical distance does not meet the requirements, return to S10 for adjustment.

[0132] Step S80, determining whether the electromagnetic environment of the photovoltaic power station meets the requirements.

[0133] In this step, based on the electromagnetic calculation function of the transmission line 3D design software, check whether the electromagnetic environment meets the requirements. If the induced voltage derived in the section is too large, greater than the personal safety induced overvoltage 24V, and does not meet the project requirements, return to S10 for re-screening.

[0134] Step S90, determining the final layout plan. In this step, the layout area and layout method of the photovoltaic power station are determined, and the construction of the photovoltaic power station is carried out.

[0135] In order to implement the above-mentioned embodiment, the present application also proposes a photovoltaic power station layout method based on the three-dimensional design results of the transmission line.
