[0026] Lightning disasters, as one of the world's most severe natural disasters, pose a serious threat to human society. As a region frequently hit by lightning, my country has, through decades of technological accumulation, developed a comprehensive lightning protection system encompassing lightning arresters, grounding devices, and surge protection. However, traditional lightning protection technologies face significant challenges in terms of protection thresholds, response speed, and environmental adaptability, necessitating iterative upgrades in protective effectiveness through technological innovation. Plasma Lightning Protectors (PLPs) are a novel type of lightning protection device that overcomes the energy dependence limitations of traditional lightning protection devices, enabling active intervention and energy dissipation of lightning leaders. They can be used for lightning protection of existing photovoltaic power plants in high-altitude mountainous areas. However, due to the unique environmental characteristics of these plants, the placement of PLPs is critical. Optimizing PLP installation locations to ensure efficient lightning protection while saving costs is a pressing technical challenge.

[0027] To address the aforementioned issues, this application discloses a method and related apparatus for calculating the installation location of plasma lightning arresters (PLPs). The aim is to improve lightning protection efficiency by quantifying terrain factors and dynamically adjusting the protection range of the PLP, while simultaneously reducing equipment procurement and installation costs by optimizing the spacing.

[0028] The following describes the calculation method for the installation location of the plasma surge arrester involved in the embodiments of this application. Please refer to... Figure 1 , Figure 1 This is a schematic flowchart illustrating a method for calculating the installation location of a plasma lightning arrester, as provided in an embodiment of this application. Figure 1 As shown, the method includes the following steps: Step S110: Calculate the distribution range of the target equipment in the photovoltaic power station, determine the terrain parameters of the terrain where the target equipment is located, and determine the lightning protection level of the target equipment based on the terrain parameters.

[0029] The terrain parameters include altitude and slope data. The distribution range of the target equipment at the photovoltaic power station is statistically analyzed, and the highest altitude of the target equipment and the slope of its location are calculated to determine the appropriate lightning protection level for the target equipment.

[0030] Specifically, in one possible embodiment, determining the lightning protection level of the target device based on terrain parameters includes: determining the device height of the target device, which includes at least one of the following: solar photovoltaic panels, controllers, inverters, irradiators, and combiner boxes; and determining the lightning protection level of the target device corresponding to the device height and terrain parameters according to preset rules.

[0031] Step S120: Calculate the protection radius and installation height of the first and second surge arresters based on the lightning protection level of the target equipment.

[0032] In one possible embodiment, calculating the protection radius and installation height of the first and second surge arresters includes: determining the protection radius of the first and second surge arresters based on the lightning protection level of the target equipment; and determining the installation height of the first and second surge arresters based on their protection radii.

[0033] Specifically, photovoltaic power stations belong to Class III lightning protection buildings, therefore a protection radius of 60m is used. The specified installation height of the PLP is a pre-defined rule and can be raised or lowered according to actual conditions. Please refer to [link / reference] for details. Figure 2 , Figure 2 This is a schematic diagram of a scenario where the protection range of a PLP is provided in an embodiment of this application, such as... Figure 2 As shown, 210 is a PLP with an installation height of h and a protection radius of 10h.

[0034] Specifically, a rectangular coordinate system is established with the first lightning arrester as the origin, the vertical direction of the first lightning arrester as the Y-axis, and the horizontal direction as the X-axis. Please refer to the following formula: (1); (2); (3); (4); Among them, the protection radius r of the first and second lightning arresters on the ground is calculated, and the height of the first lightning arrester relative to the coordinate axis is calculated. h 1, and the height of the second lightning arrester relative to the coordinate axis h 2; h A It refers to the installation height of PLP (first surge arrester) numbered A relative to the ground. h B It refers to the installation height of PLP (second lightning arrester) numbered B relative to the ground; x 2 represents the x-coordinate of the second surge arrester. The protection radius of a single PLP on the ground is approximately equal to 10 times its installation height, and this value changes with the environment.

[0035] Step S130: Determine the first protection range of the first surge arrester and the second protection range of the second surge arrester based on the protection radius and installation height.

[0036] Among them, based on the above rectangular coordinate system, the mathematical function expressions for the protection range of the first lightning arrester are calculated respectively. y A Mathematical function expression of the protection range of the first and second lightning arresters y B And the mathematical function expression for calculating the ground y 地 Please refer to the following formula for details: (5); (6); (7); (8); (9); Where x2 is the x-coordinate of the installation position numbered B; h1 is the height of PLP numbered A relative to the coordinate axis; h2 is the height of PLP numbered B relative to the coordinate axis; θ The slope angle of the ground.

[0037] Step S140: Determine the intersection position of the protection ranges of the first surge arrester and the second surge arrester based on the first protection range and the second protection range.

[0038] By combining equations (6) and (8), the ordinate of the intersection point of the protection ranges of the first and second surge arresters can be obtained. Please refer to the following formula for details: (10); By combining equations (5) and (7), the x-coordinate of the intersection point of the protection ranges of the first and second surge arresters can be obtained. Please refer to the following formula for details: (11); Step S150: Determine the installation positions of the first and second surge arresters based on the intersection of the protection ranges.

[0039] Based on the above expression, the solution is... x 2. This yields the furthest installation distance between two surge arresters that meet the protection requirements. Specifically, this can be extended to optimize the most economical placement of three or more surge arresters while meeting the protection requirements.

[0040] As can be seen, the method provided in this application firstly involves statistically analyzing the distribution range of target equipment in the photovoltaic power station to determine the terrain parameters of the terrain where the target equipment is located. Based on these terrain parameters, the lightning protection level of the target equipment is determined. The terrain parameters include altitude and slope data. Secondly, based on the lightning protection level of the target equipment, the protection radius and installation height of the first and second surge arresters are calculated. Next, based on the protection radius and installation height, the first protection range of the first surge arrester and the second protection range of the second surge arrester are determined. Then, based on the first and second protection ranges, the intersection of the protection ranges of the first and second surge arresters is determined. Finally, based on the intersection of the protection ranges, the installation positions of the first and second surge arresters are determined. In this way, by quantifying terrain factors and dynamically adjusting the protection range of the PLP (Lightning Protection Plug-in), lightning protection efficiency is improved, while the equipment procurement and installation costs are reduced by optimizing the spacing.

[0041] In one possible embodiment, determining the intersection of the protection ranges of the first and second surge arresters includes: establishing a rectangular coordinate system with the location of the first surge arrester as the origin, the vertical direction of the first surge arrester as the longitudinal axis, and the horizontal direction as the transverse axis; determining the expressions for the first and second protection ranges in the rectangular coordinate system; determining the horizontal and longitudinal coordinates of the intersection of the protection ranges based on the expressions for the first and second protection ranges; determining the ground height in the rectangular coordinate system; and determining the relative height of the intersection of the protection ranges based on the horizontal and longitudinal coordinates of the intersection and the ground height, wherein the relative height is used to characterize the height of the intersection of the protection ranges relative to the ground.

[0042] Specifically, please refer to Figure 3 , Figure 3 This is a schematic diagram of a scenario where the protection range of a lightning arrester intersects, as provided in an embodiment of this application. Figure 3 As shown, it includes a first lightning arrester 310 and a second lightning arrester 320.

[0043] The boundaries of the expressions for the first and second protection ranges are linear functions, represented by a point-slope form. The first protection range is: (5); The second protection scope is: (7); Among them, the vertical coordinate of the intersection point of the protection range of the first lightning arrester 310 and the second lightning arrester 320 is the distance of the intersection point relative to the x-axis, and the horizontal coordinate is the distance of the intersection point relative to the y-axis. Please refer to the above formulas (10) and (11).

[0044] The relative height is calculated by subtracting the ground height from the coordinate axis from the height of the intersection point relative to the coordinate axis. The placement of lightning arresters is optimized by setting the relative height. The relative height Δ... y Please refer to the following formula for details: (12) As can be seen, in this embodiment, by calculating the relative height and setting a threshold, the interference of the slope of the plateau mountainous terrain on the protection height is reduced, and the accurate quantification of the true and effective protection height of the cross protection range of the lightning arrester is achieved. This is conducive to balancing the effectiveness of lightning protection for the main equipment of the photovoltaic power station with the economy of the deployment, while reducing the overall cost of equipment procurement and installation.

[0045] Specifically, please refer to Figure 4 , Figure 4 This is a schematic flowchart illustrating a specific process for determining the installation location of a surge arrester, provided in an embodiment of this application. In one possible embodiment, the installation locations of the first and second surge arresters are determined based on the intersection of their protection ranges, such as... Figure 4 The steps shown are as follows: S401. Determine the slope coefficient based on the slope aspect, slope, and the first empirical coefficient.

[0046] The first empirical coefficient is related to the slope; the steeper the slope, the larger the first empirical coefficient. Slope and aspect affect the probability of lightning strikes at a given location, which is known as the slope coefficient. Applying this slope coefficient to the subsequent correction of the lightning arrester's installation location makes the installation of the lightning arrester more economical and safer.

[0047] Specifically, the expression for the slope coefficient is as follows: (13); in, θ It is the slope angle at the intersection of the protected area, in degrees (°); along the uphill direction, compared with flat ground, the probability of lightning strike gradually increases with the increase of slope, and the trend is getting faster and faster; along the downhill direction, compared with flat ground, the probability of lightning strike gradually decreases with the increase of slope, and the trend is getting faster and faster. Therefore, the calculation symbol in the uphill direction determination formula (13) is "+", and the calculation symbol in the downhill direction determination formula (13) is "-". a This is the first empirical coefficient, usually taken as 0.2~0.5. Please refer to Table 1: The Influence of Slope on the Value of 'a' and Its Physical Meaning: Table 1

[0048] S402. Determine the altitude of the intersection of the protected areas.

[0049] S403. Determine the altitude coefficient based on the altitude and the second empirical coefficient.

[0050] The second empirical coefficient is correlated with altitude; the higher the altitude, the larger the second empirical coefficient. Altitude data affects the probability of lightning strikes at a given location, hence the altitude coefficient. Applying this slope coefficient to the subsequent correction of the lightning arrester's installation location makes the installation of the lightning arrester more economical and safer.

[0051] Specifically, the expression for the altitude coefficient is as follows: (14); The formula can be divided into two parts by the "+" sign. The first part describes the decrease in lightning strike density at low altitudes with increasing altitude, while the second part describes the increase in lightning strike density at mid-altitudes due to the gradually strengthening airflow lifting effect as altitude increases. Specifically, k This is the second empirical coefficient, usually taken as 0.1~0.5, as shown in Table 2: The Influence of Slope on the Value of k and Its Physical Meaning: Table 2

[0052] S404. The distance between the first and second lightning arresters is determined based on the slope coefficient, altitude coefficient, and relative height.

[0053] Specifically, the expression for relative height is as follows: (15); in, These are preset values, assuming an altitude of 0 meters and a slope of 0 degrees. =2 m .

[0054] By combining equations (12) and (15) above, we can obtain... x 2 represents the horizontal coordinate of the second lightning arrester, which is also the horizontal distance between the first and second lightning arresters.

[0055] S405. Determine the installation positions of the first and second surge arresters based on the distance between them.

[0056] Specifically, in one possible embodiment, determining the distance between the first and second lightning arresters based on the slope coefficient, altitude coefficient, and relative height includes: determining an expression for the relative height based on the slope coefficient, altitude coefficient, and preset height; and determining the abscissa of the second lightning arrester in a Cartesian coordinate system based on the expression for the relative height and the relative height, wherein the abscissa of the second lightning arrester is the distance between the first and second lightning arresters.

[0057] Among them, based on the distance between the first surge arrester and the second surge arrester, the furthest installation distance that meets the protection conditions of the first surge arrester and the second surge arrester is determined to be the same. x 2.

[0058] For example, suppose a 50MW mountain photovoltaic power station is located in a region prone to thunderstorms. The site is situated at an altitude of 2000m on a windward slope with a gradient of 20°. Lightning arresters are installed at a uniform installation height of 20m. Let the following be calculated: ; Furthermore, let the slope coefficient be: ; Furthermore, let the altitude coefficient be: (14) Then, the final result is obtained x 2:

[0059] This means that a distance of 72.94 meters between the two lightning arresters can meet the protection requirements in the most economical way.

[0060] As can be seen, in this embodiment, by substituting the relative height of the protection height, the slope coefficient, the altitude coefficient, and the preset values ​​that vary with altitude and slope into the solution with the horizontal coordinate of the installation position of the second surge arrester as the variable, the farthest installation distance of the two surge arresters under the protection conditions is accurately quantified. This improves the scientificity and adaptability of the surge arrester placement in high-altitude mountain photovoltaic power stations, and is conducive to maximizing the installation spacing of surge arresters, reducing equipment redundancy investment, and balancing the reliability of lightning protection for main equipment with the economy of placement.

[0061] This application embodiment can divide the electronic device into functional units according to the above method example. For example, each function can be divided into a separate functional unit, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software functional unit. It should be noted that the unit division in this application embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.
