Abstract
Description
Technical Field
[0001] This application relates to the field of power system protection technology, and in particular to a method and related apparatus for determining the installation location of a photovoltaic power plant's PLP (Power Line Protection) system. Background Technology
[0002] Photovoltaic power plants are mostly located in mountainous and desert areas with high solar radiation intensity. Lightning activity is more frequent in these areas than in cities. In particular, due to the complex terrain and special climate of plateau and mountainous areas, lightning is characterized by high frequency and strong destructiveness, which significantly increases the risk of lightning strikes to photovoltaic power plants.
[0003] Plasma Lightning Protectors (PLPs), as a new type of non-lightning-contact surge protection device, passively release 10-30mA ionization dissipation current to neutralize the potential difference between thunderclouds and induced charges on the ground, preventing the formation of a leader discharge channel. This can effectively reduce lightning-induced tripping accidents by more than 80%, improve power supply reliability, and reduce operation and maintenance costs. Currently, PLPs are typically installed directly at the top of slopes without considering the impact of slope gradient and aspect on the protection range, making it difficult to select a suitable installation location and resulting in poor protection effectiveness.
[0004] Therefore, selecting a suitable installation location for the PLP has become an urgent problem to be solved. Summary of the Invention
[0005] This application provides a method and related apparatus for determining the installation location of a photovoltaic power plant's PLP (Plug-in Propulsion) system, which can select a suitable installation location for the PLP.

[0007] Secondly, embodiments of this application provide a device for determining the installation location of a photovoltaic power station's PLP (Plug-in Photovoltaic Power Plant), comprising: an acquisition unit and a location determination unit, wherein: The acquisition unit is used to acquire the target area where the target photovoltaic power station is located; and to acquire the target terrain data and lightning activity dataset corresponding to the target area; The location determination unit is used to determine target terrain factors based on the target terrain data; and to determine the direction of target evolution trend based on the target terrain factors and the lightning activity dataset.

[0011] Implementing this application will have the following beneficial effects: As can be seen, the method for determining the PLP installation location of a photovoltaic power station described in this application solves the problem of "ignoring environmental differences" in the prior art by acquiring target terrain data and lightning activity data of the target area, ensuring that the installation location is adapted to the terrain features and conforms to the lightning distribution pattern. Next, the target evolution trend direction (the direction dominated by thunderclouds) is determined by combining the target terrain factors and the lightning activity dataset, so that the installation location is accurately aligned with the direction of high lightning incidence, avoiding protection blind spots. Then, the target deviation value is calculated by combining the basic information of the PLP equipment to achieve a quantitative match between the equipment capability and environmental requirements, rather than blindly selecting a site. Finally, the preset position is adjusted based on the target evolution trend direction and the target deviation value, so that the installation location simultaneously meets the three core requirements of "adapting to the terrain, aligning with the direction dominated by lightning, and matching the protection effectiveness of the PLP", thereby determining the appropriate installation location of the PLP.

[0021] Of course, the aforementioned electronic devices can also be servers, such as cloud servers.
[0022] The following describes the relevant content, concepts, meanings, technical issues, technical solutions, and beneficial effects involved in the embodiments of this application.
[0023] First, let me explain some of the technical terms used in this application: PLP: short for "Plasma Lightning Protector", is a new type of lightning protection device that does not rely on lightning strike mechanism. It continuously releases ionization dissipation current in the range of 10~30mA in a passive state to neutralize the potential difference of induced charges between thunderclouds and the ground, preventing the formation of leader discharge channels, thereby achieving lightning protection for photovoltaic power stations.
[0024] The direction of lightning evolution: also known as the "direction of lightning cloud-dominated evolution", refers to the dominant direction of the most frequent lightning cloud activity, movement or aggregation in the area where the target photovoltaic power station is located. It is determined by the topographic factors (slope, aspect) of the area and the lightning activity data set (distribution of ground flashes, intensity, etc.), and is the core basis for aligning the PLP installation location with the direction of high lightning incidence.
[0025] Peak ground flash current: refers to the maximum current value generated during lightning discharge to the ground (ground flash), measured in kiloamperes (kA). It is obtained through lightning location systems, meteorological data, etc., and is a key parameter for quantifying the intensity of lightning damage in a region and calculating the lightning activity index.
[0026] Ground flash density: refers to the number of ground flashes occurring in a target area per unit time and unit area, measured in flashes per (km²). a) (times per square kilometer per year) reflects the frequency of lightning activity in the region. It is obtained through statistical analysis of historical lightning observation data and is an important reference for adapting the installation location of PLP to the lightning distribution pattern.
[0027] RTK (Real-Time Kinematic) mapping equipment is a device that uses real-time dynamic positioning technology for high-precision measurement and positioning. It typically consists of two parts: a rover station and a base station. The rover station is used to collect measurement data and perform real-time positioning, while the base station provides known location information and reference signals for phase difference calculations to improve positioning accuracy.
[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of a target PLP provided in an embodiment of this application; it can be seen that the target PLP includes: an array of lightning rods, a rod base, a base, etc., which are not limited here, wherein: Array lightning rods: Distributed in a multi-branched, divergent pattern at the top of the device, they are the core component for the target PLP to achieve lightning protection. Through the array layout of multiple rods, they expand the release range of ionization dissipation current and can passively release ionization current in the range of 10~30mA, neutralizing the potential difference of induced charges between thunderclouds and the ground, thereby preventing the formation of leader discharge channels and meeting the large-area protection needs of photovoltaic power stations.
[0029] Needle base: Located below the array of lightning rods, it is the centralized load-bearing and connecting component for each lightning rod. It is used to fix and gather all the needle rods to ensure the stability of the array layout. At the same time, it is also the mounting carrier for the internal functional components of the target PLP (such as ionization-related structures), supporting the needle rods to achieve a coordinated charge neutralization effect.
[0030] Base: Located at the bottom of the device, it is the support and installation component for the target PLP. It is used to fix the entire target PLP in the installation position of the photovoltaic power station, ensuring the installation stability of the device in complex terrains such as mountains and slopes, and providing basic support for the target PLP to continuously perform its lightning protection function.
[0031] Please see Figure 2 , Figure 2 This is an application scenario diagram of a target PLP provided in an embodiment of this application. It can be seen that the target PLP is deployed in a key location of the photovoltaic power station (the optimal installation location is determined by the PLP installation location determination method of the photovoltaic power station provided in this application). It is the core component of the power station's lightning protection system and undertakes the non-lightning protection function for the core equipment of the entire power station.
[0032] In addition, the target photovoltaic power station may include: photovoltaic power generation equipment, combiner boxes, controllers, transformers, energy storage equipment, etc., without limitation, among which: Photovoltaic power generation equipment: The source of power generation in the station, which is within the protection range of the PLP to prevent physical damage or power generation failure due to lightning strikes (direct impact or electromagnetic induction); Combiner box: It is responsible for collecting the DC power output from photovoltaic equipment. It is a device that is susceptible to lightning induction. The protection of PLP can reduce its risk of lightning overvoltage. Controller: It coordinates the operation and control of the equipment in the site. The target PLP must be protected from lightning electromagnetic interference to ensure the stable transmission of control commands. Transformer: It realizes the voltage conversion of electrical energy (to adapt to grid connection or energy storage needs) and is a high-value key equipment. Protection of the target PLP can reduce the operation and maintenance costs of lightning damage. Energy storage equipment: Stores surplus electrical energy in the site. Protection of the target PLP can prevent it from malfunctioning or even causing safety hazards (e.g., battery short circuit) due to lightning strikes.
[0033] Please see Figure 3 , Figure 3 This is a flowchart illustrating a method for determining the installation location of a PLP (Plug-in Power Supply) in a photovoltaic power station, as provided in an embodiment of this application. The method includes, but is not limited to, the following steps: S301. Obtain the target area where the target photovoltaic power station is located.
[0034] In this embodiment of the application, the target photovoltaic power station can be a photovoltaic power station in a plateau or mountainous area.
[0035] In a specific embodiment, surveying equipment (e.g., RTK surveying instrument, UAV aerial surveying equipment, etc.) can be used to collect the coordinates of the core points of the target photovoltaic power station (e.g., the latitude and longitude of the center point of the power station and the four corner boundary points of the photovoltaic array area) to determine its basic geographical location as a benchmark for regional positioning; then, the actual land area of the power station (including the photovoltaic module area, equipment area, supporting facilities area, etc.), i.e. the target area, can be determined by UAV aerial surveying and on-site surveying.
[0036] S302. Obtain the target terrain data and lightning activity dataset corresponding to the target area.
[0037] In this embodiment of the application, the target terrain data may include information such as slope, aspect, and terrain units, which are not limited here; the lightning activity dataset may include information such as lightning location, lightning peak current, and lightning density, which are not limited here.
[0038] In a specific embodiment, the latitude and longitude range of the target area can be determined first. Based on the latitude and longitude range, the digital elevation model (DEM) data of the target area can be downloaded from a preset geographic database. Then, the slope, aspect and other terrain parameters can be extracted from the DEM data through a geographic information system to obtain the target terrain data. Alternatively, surveying tools can be used to conduct on-site surveying of the photovoltaic power station and its surrounding area to generate a high-precision terrain model and directly obtain data such as slope, aspect and terrain undulation, which is the target terrain data.
[0039] Next, a preset meteorological database can be accessed to obtain historical lightning observation data for the target area, thus obtaining a lightning activity dataset. Alternatively, lightning detection equipment can be installed in the target area. Specifically, multiple equipment detection points can be determined first. For example, 3 to 5 equipment detection points can be evenly distributed within a 2-3 km radius of the core area of the site (e.g., photovoltaic array area, equipment concentration area) and its surrounding area (adjustable according to the scale of the site). The equipment detection points should avoid obstructions (such as tall trees and buildings) and should be preferably located in open areas (such as the edge pillars of the site, the top of the support frame) to ensure that the detection signal is unobstructed. The lightning detection equipment is then installed at these equipment detection points. In this way, lightning activity data in the target area can be continuously collected through the lightning detection equipment, thus obtaining a lightning activity dataset.
[0040] The lightning detection equipment may include at least one of the following: ground flash detection sensor (e.g., pulse current lightning counter), lightning location system, electric field monitor, etc., without limitation.
[0041] S303. Determine the target terrain factor based on the target terrain data.
[0042] In this embodiment of the application, target terrain factors can be directly extracted from target terrain data. For example, target terrain factors may include slope and aspect.
[0043] Specifically, the two topographic factors, slope and aspect, are defined as follows: for any point on the Earth's surface, the angle between the tangential plane passing through that point and the horizontal plane represents the slope at that location, reflecting the degree of inclination of the terrain. In this embodiment, 0° is defined as true north, and the angle between clockwise and true north represents the aspect. For details, please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a schematic diagram of a slope angle division provided in an embodiment of this application. It can be seen that, with due north as the 0° reference, a slope angle interval is divided every 45° in a clockwise direction; each interval corresponds to a slope angle (north, northeast, east, southeast, south, southwest, west, northwest). Figure 4 The angle indicated by the middle arrow is the clockwise boundary of each interval; as detailed below: North: corresponds to 0°~22.5° or 337.5°~360° ( Figure 4 (22.5° and 337.5° are the two boundary angles of the north slope). Northeast: Corresponding to 22.5°~67.5° ( Figure 4 (67.5° is its clockwise boundary). East: Corresponding to 67.5°~112.5° ( Figure 4 112.5° is its clockwise boundary). Southeast: Corresponding to 112.5°~157.5° ( Figure 4 157.5° is its clockwise boundary). South: Corresponding to 157.5°~202.5° ( Figure 4 202.5° is its clockwise boundary). Southwest: Corresponding to 202.5°~247.5° ( Figure 4 247.5° is its clockwise boundary). West: Corresponding to 247.5°~292.5° ( Figure 4 292.5° is its clockwise boundary). Northwest: Corresponding to 292.5°~337.5° ( Figure 4 The 337.5° mark is its clockwise boundary, connecting the 337.5°~360° range of the north slope.
[0044] S304. Determine the direction of the target evolution trend based on the target terrain factors and the lightning activity dataset.
[0045] In this embodiment of the application, the lightning activity dataset can be analyzed based on the target terrain factors in order to determine the evolution trend direction of lightning activity within the target area, that is, the target evolution trend direction.
[0046] Optional, please refer to Figure 5 , Figure 5 This is a flowchart of a method for determining the direction of target evolution trend according to an embodiment of this application. As can be seen, step S304, determining the direction of target evolution trend based on the target terrain factors and the lightning activity dataset, includes, for example... Figure 5 The steps shown are as follows: S41. Determine the target lightning density map based on the lightning activity dataset; S42. Determine the reference evolution trend direction based on the target lightning density map; S43. Correct the reference evolution trend direction based on the target terrain factor to obtain the target evolution trend direction.
[0047] In this embodiment, a target lightning density map can be determined based on a lightning activity dataset. Specifically, the lightning activity dataset (including the occurrence time, latitude and longitude location, and identification of individual lightning events) is first organized. The target area is then divided into grid cells of equal area (e.g., 1km × 1km, with precision adjustable according to the size of the lightning field). The total number of lightning events in each grid cell within a set period (e.g., the last 3 years) is counted, and the lightning density of that grid cell is calculated. The specific formula for calculating the lightning density is as follows: Ground flash density = Total number of ground flashes ÷ Grid area ÷ Statistical duration; It should be noted that the unit of ground flash density is "flashes / (km²)". The statistical period is the set period; then, geographic information tools (such as ArcGIS and QGIS) can be used to map the lightning density value of each grid to different colors (for example, dark colors represent high density and light colors represent low density) to generate a visualized target lightning density map.
[0048] Next, the reference evolution trend direction can be determined based on the target lightning density map. Specifically, the spatial morphology of the "high-density area" in the target lightning density map can be observed: if the high-density area extends in a strip along a certain direction (for example, from southwest to northeast), the direction of extension is the reference evolution trend direction; if the target lightning density map contains multiple lightning density maps for consecutive time periods (for example, density maps for different seasons and months), then the movement trajectory of the "high-density area" in each time period can be tracked (for example, assuming that the high-density area from May to August gradually moves from northwest to southeast), and the direction of its concentrated movement is the reference evolution trend direction.
[0049] In addition, the reference evolution trend direction can be further verified: Statistical analysis of the time series of lightning occurrence locations shows that if most lightning occurrence locations are distributed sequentially along a certain direction (e.g., lightning occurs continuously from east to west within one hour), this direction is designated as the first direction. The first direction can serve as a supplementary reference direction. Specifically, the deviation angle between the reference evolution trend direction and the first direction can be determined to obtain the target deviation angle. If the target deviation angle is less than or equal to a preset angle (e.g., 30°), it indicates that the two directions are basically consistent, with no significant deviation. The macroscopic spatial distribution pattern of the thundercloud (reflected in the density map) matches the real-time movement pattern (reflected in the time series), indicating that the reference evolution trend direction is consistent with the first direction. The change in trend direction is not merely a random occurrence caused by the static density distribution, but rather a stable and dominant direction of long-term thundercloud activity; therefore, no correction is needed. If the target deviation angle is greater than the preset angle, it indicates a significant inconsistency between the two, requiring reconstruction or correction of the reference evolution trend direction. For example, suppose the main movement direction of lightning in the time series (e.g., from south to north) completely deviates from the reference evolution trend direction based on the target lightning density map (e.g., from west to east). This indicates that the "static spatial distribution" of the target lightning density map has not captured the actual dynamic movement pattern of the thundercloud (e.g., the density map, due to its excessively long statistical period, obscures the real-time movement trajectory of the thundercloud). In this case, we can: Based on the dynamic direction reflected by the time series, the reference evolution trend direction is reconstructed. For example, the first direction can be directly used as the reference evolution trend direction. If the deviation between the density map and the time series is due to differences in statistical scale (for example, the target lightning density map is on an annual scale, while the time series is on an hourly scale), then the applicable scenarios of both can be combined: the annual scale reference direction is used for the long-term layout of the field PLP, and the hourly scale time series direction is used for the adjustment of the direction of short-term lightning protection early warning, so as to realize the hierarchical application of the reference evolution trend direction.
[0050] Finally, the reference evolution trend direction can be corrected based on the target topographic factors to obtain the target evolution trend direction. Specifically, the influence mechanism of topographic factors can be clarified first: slope aspect guides airflow (thunderclouds move with airflow), and steep slopes will enhance the guiding effect of topography on airflow. Based on the slope adjustment correction range: If the slope is large (e.g., greater than 20°), it indicates that the terrain has a strong guiding effect on airflow, and the reference evolution trend direction needs to be adjusted by a large angle towards the dominant slope direction (e.g., from northeast to northeast-northwest); if the slope is small (e.g., less than 5°), the terrain has a weaker influence, and only the reference evolution trend direction needs to be slightly adjusted. Final integration and correction: Combining the "dominant guiding direction of slope aspect" and the "influence intensity of slope gradient", the angle of the reference evolution trend direction is corrected, thereby obtaining the target evolution trend direction adapted to the terrain of the target photovoltaic power station. Among them, slope aspect determines the "direction" of the correction of the reference direction (which direction to adjust), and slope gradient determines the "angle range" of the correction (how many degrees to adjust). The combination of the two realizes the quantitative correction of the reference evolution trend direction.
[0051] Thus, by transforming lightning activity datasets into target lightning density maps and converting scattered lightning data into intuitive spatial distribution patterns, we can accurately identify the spatial clustering characteristics of high-incidence lightning events, providing an objective basis for determining the direction of evolution trends, rather than relying solely on subjective judgment based on experience.
[0052] In addition, the reference direction is corrected by terrain factors, which makes up for the deficiency of only considering the lightning pattern but ignoring the guiding effect of terrain on thunderclouds. This ensures that the final target evolution trend direction is consistent with the slope and aspect characteristics of the photovoltaic power station, and that the PLP installation position can be accurately aligned with the actual high-incidence direction of lightning after being affected by the terrain, thereby reducing protection blind spots from the root.
[0053] S305. Obtain the preset installation location and basic equipment information corresponding to the target PLP.
[0054] In this embodiment of the application, the preset installation location can be preset in advance or defaulted, for example, the top of the slope in the target area.
[0055] In a specific embodiment, a preset installation location can be obtained first, followed by obtaining the technical documentation of the target PLP and querying the basic information of the device from the technical documentation. Alternatively, the target PLP can be tested in the field. Test the actual ionization current output value and correct the protection parameters in the technical documents; Measure the installation height of the target PLP; Simulating the stability of equipment installation under different terrains (e.g., steep slopes, flat slopes), determining the actual installation compatibility conditions, etc., are not limited here; In this way, basic equipment information can be obtained.
[0056] S306. Determine the target deviation value based on the target terrain factor, the lightning activity dataset, the target evolution trend direction, and the basic equipment information.
[0057] In this embodiment of the application, the target terrain factors, lightning activity dataset, target evolution trend direction and basic equipment information can be analyzed to determine the target deviation value.
[0058] Optionally, step S306, determining the target deviation value based on the target terrain factor, the lightning activity dataset, the target evolution trend direction, and the equipment basic information, includes: A1. Determine the target protection radius corresponding to the target PLP based on the target terrain factors, the lightning activity dataset, the target evolution trend direction, and the basic equipment information; A2. Determine the target deviation value corresponding to the target protection radius.
[0059] In this embodiment of the application, the target protection radius can be determined by analyzing and calculating based on the target terrain factors, lightning activity dataset, target evolution trend direction and basic equipment information; then, the corresponding target deviation value can be calculated based on the target protection radius.
[0060] In this way, the target deviation value is calculated based on the adapted target protection radius, transforming the "deviation from the preset installation position to the optimal position" into a specific quantitative indicator, replacing the subjective position adjustment method. This target deviation value can accurately guide the PLP installation position to move along the target evolution trend direction and combine terrain factors to ensure that the final installation position matches the target protection radius, maximizing the lightning protection function of the PLP.
[0061] Optionally, the target terrain factors include: slope and aspect; the basic equipment information includes: the installation height of the target PLP; step A1, determining the target protection radius corresponding to the target PLP based on the target terrain factors, the lightning activity dataset, the target evolution trend direction, and the basic equipment information, includes: B1. Determine the initial protection radius corresponding to the target PLP based on the installation height of the target PLP and the first preset calculation formula; the first preset calculation formula is as follows:
[0062] in, This represents the initial protection radius. This indicates the installation height of the target PLP. This indicates the preset standard rolling ball radius; B2. Determine the angle between the slope direction and the direction of the target evolution trend to obtain the first angle; B3. Determine the terrain factor coefficient based on the slope, the first included angle, and the second preset calculation formula; the second preset calculation formula is as follows:
[0063] in, This represents the terrain factor coefficient. Indicates the slope. Indicates the first included angle. This indicates the preset slope sensitivity coefficient. This indicates the preset aspect sensitivity coefficient; B4. Determine the lightning activity index based on the lightning activity dataset; B5. Determine the target protection radius based on the lightning activity index, the terrain factor coefficient, the initial protection radius, and the third preset calculation formula; the third preset calculation formula is as follows:
[0064] in, Indicates the target protection radius, This represents the preset lightning weighting coefficient. This indicates the lightning activity index.
[0065] In this embodiment of the application, the first preset calculation formula, the second preset calculation formula, and the third preset calculation formula can all be preset in advance or defaulted.
[0066] In a specific embodiment, the installation height of the target PLP can be substituted into the first preset calculation formula, which is as follows:
[0067] The initial protection radius can be calculated based on the first preset calculation formula mentioned above. It should be noted that the first preset calculation formula is the calculation formula of the rolling ball method.
[0068] In some embodiments, the target lightning protection standard of the target photovoltaic power station can be obtained, and the standard rolling sphere radius can be determined based on the target lightning protection standard. Different lightning protection standards correspond to different radii. For example, if the target lightning protection standard is a Class I lightning protection standard, then the standard rolling sphere radius is... It can be set to 20m. If the target lightning protection standard is Class II lightning protection standard, the standard rolling sphere radius is... It can be set to 45m, and so on.
[0069] Then, the angle between the slope aspect and the direction of the target evolution trend can be determined to obtain the first angle. Specifically, it can be based on... Figure 4 The slope angle division shown determines the first angle corresponding to the slope aspect. Similarly, the second angle corresponding to the direction of the target's evolution trend can also be determined. The initial angle difference is determined based on these two angle values, as detailed below:
[0070] in, Indicates the initial angle difference. Indicates the first angle. This represents the second angle. For example, assuming the first angle is 315° and the second angle is 20°, |315°-20°|=295°, meaning the initial angle difference is 295°. Since the angle between the two directions must be less than or equal to 180°, if the initial angle difference is greater than 180°, then subtract the initial angle difference from 360°, i.e., 360°-295°=65°. This 65° is the first angle between the slope direction and the direction of the target evolution trend. If the initial angle difference is less than or equal to 180°, then the initial angle difference can be directly used as the first angle.
[0071] Then, the slope and the first included angle can be substituted into the second preset calculation formula, which is as follows:
[0072] The terrain factor coefficient can be obtained by calculating according to the second preset calculation formula mentioned above. Next, the lightning activity index can be determined based on the lightning activity dataset. Then, the lightning activity index, topographic factor coefficient, and initial protection radius can be substituted into the third preset calculation formula, which is as follows:
[0073] The target protection radius can be obtained by calculating using the third preset calculation formula mentioned above. .
[0074] In some embodiments, lightning weighting coefficient It can be 0.05.
[0075] Thus, by calculating the initial protection radius using the rolling sphere method (a general standard for lightning protection), it is ensured that it meets the basic requirements of lightning protection engineering and avoids deviation from industry standards; In addition, by combining slope, first included angle and sensitivity coefficient, the "interference of terrain on the protection range" is transformed into a calculable terrain factor coefficient, replacing subjective experience judgment, so that the impact of terrain on the protection range is accurately implemented; then, the protection radius is adjusted by combining the actual lightning data of the site, so that the protection range matches the lightning intensity.
[0076] Optionally, step A2, determining the target deviation value corresponding to the target protection radius, includes: The target deviation value is determined based on the target protection radius and the fourth preset calculation formula; the fourth preset calculation formula is as follows:
[0077] in, This represents the deviation value from the target.
[0078] In this embodiment of the application, the fourth preset calculation formula can be preset in advance or defaulted.
[0079] In a specific embodiment, the target protection radius and the first included angle can be substituted into the fourth preset calculation formula to calculate the target deviation value.
[0080] Thus, by combining the sine value of the first included angle (reflecting the angular relationship between the slope direction and the lightning direction) and the target protection radius (reflecting the protection range) for calculation, the target deviation value can be matched with the coverage requirements of the protection range, ensuring that the adjusted position allows the PLP's protection range to accurately cover the direction of high lightning incidence and eliminate protection blind spots.
[0081] Optionally, the lightning activity dataset includes *a* lightning activity data points; *a* is an integer greater than 1; step B4, determining the lightning activity index based on the lightning activity dataset, includes: C1. Determine the peak ground flash current and ground flash density corresponding to each of the a lightning activity data, and obtain a peak ground flash currents and a ground flash densities; C2. Determine the maximum ground flash peak current among the a ground flash peak currents; C3. Determine the lightning density corresponding to the maximum lightning peak current in the a lightning densities to obtain the target lightning density; C4. Determine the lightning activity index based on the target lightning density, the maximum lightning peak current, and the fifth preset calculation formula; the fifth preset calculation formula is as follows:
[0082] in, This indicates the lightning activity index. This indicates the target ground flash density. This represents the maximum peak ground flashover current. This indicates the preset reference current.
[0083] In this embodiment of the application, the fifth preset calculation formula can be preset in advance or defaulted.
[0084] In a specific embodiment, the peak lightning current and lightning density corresponding to each lightning activity data point in a data set of lightning activity can be determined, resulting in a peak lightning current and a lightning density. Specifically, for each lightning activity data point, outliers can be removed first, such as values with a current of 0 or location coordinates exceeding the target area. Then, all lightning currents are extracted, and the maximum value among these lightning currents is determined to obtain the peak lightning current. Next, the number of lightning currents (i.e., the total number of lightning strikes) can be determined. The area of the target region is obtained from the target terrain data. Finally, the lightning activity data can be determined. The data collection duration corresponding to the lightning activity data can be specifically obtained from the metadata documentation of the lightning activity data, which will directly indicate the data collection duration, for example, "Lightning data of the target area from 2020 to 2024, data collection duration of 5 years". If the metadata documentation does not indicate this, the earliest and latest timestamps of all records can be extracted from the lightning activity data, and the time difference between the two can be calculated as the data collection duration. These data can then be substituted into the lightning flash density calculation formula to obtain the lightning flash density. In this way, a peak lightning currents and a lightning flash densities can be obtained.
[0085] Then, the maximum flash current among the *a* flash currents can be determined. Specifically, the *a* flash currents can be compared pairwise to find the maximum value, which is the maximum flash current. Next, the flash density corresponding to the maximum flash current among the *a* flash densities can be determined to obtain the target flash density. Specifically, the timestamp corresponding to the maximum flash current can be obtained to obtain the target timestamp. Based on the target timestamp, the corresponding flash density can be found from the *a* flash densities, which is the target flash density. Furthermore, the target flash density and the maximum flash current can be substituted into the fifth preset calculation formula, which is as follows:
[0086] The lightning activity index can be calculated using the fifth preset calculation formula.
[0087] In some embodiments, the reference current It can be 30kA; In this way, by selecting the maximum peak ground flash current (representing the maximum destructive force of a lightning strike) and matching it with its corresponding ground flash density (reflecting the frequency of occurrence of such a strong lightning strike), risk assessment bias caused by focusing solely on intensity or frequency can be avoided. In addition, the combined risk of "density and peak current" is transformed into a specific lightning activity index through a formula, replacing the subjective risk level classification and achieving a quantitative and unified lightning risk assessment.
[0088] Optionally, the method further includes: D1. Determine the reference slope sensitivity coefficient and reference aspect sensitivity coefficient corresponding to the target photovoltaic power station; D2. Determine the deviation between the lightning activity index and the preset activity index to obtain the target deviation. D3. Determine the first adjustment coefficient corresponding to the target deviation; D4. Determine the target photovoltaic equipment density corresponding to the target photovoltaic power station; D5. Determine the second adjustment coefficient corresponding to the target photovoltaic equipment density; D6. Adjust the reference slope sensitivity coefficient according to the first adjustment coefficient to obtain the preset slope sensitivity coefficient; D7. Adjust the reference aspect sensitivity coefficient according to the second adjustment coefficient to obtain the preset aspect sensitivity coefficient.
[0089] In this embodiment of the application, the preset activity index can be preset in advance or set by default.
[0090] In a specific embodiment, the reference slope sensitivity coefficient and reference aspect sensitivity coefficient corresponding to the target photovoltaic power station can be determined. Specifically, the target lightning protection standard of the target photovoltaic power station can be obtained, and the reference slope sensitivity coefficient and reference aspect sensitivity coefficient can be determined according to the target lightning protection standard. For example, a preset mapping relationship between the lightning protection standard and the slope sensitivity coefficient and aspect sensitivity coefficient can be stored in advance, and the reference slope sensitivity coefficient and reference aspect sensitivity coefficient corresponding to the target lightning protection standard can be determined based on the mapping relationship.
[0091] Next, the deviation between the lightning activity index and the preset activity index can be determined, as follows: Target deviation = |Lightning activity index - Preset activity index| ÷ Preset activity index × 100%; Based on the above formula, the target deviation can be obtained. Then, the first adjustment coefficient corresponding to the target deviation can be determined. Specifically, a pre-stored mapping relationship between the deviation and the adjustment coefficient can be used to determine the first adjustment coefficient corresponding to the target deviation. Next, the target photovoltaic equipment density corresponding to the target photovoltaic power station can be determined. Specifically, the power station design document of the target photovoltaic power station can be obtained. The number of photovoltaic devices included in the target photovoltaic power station can be determined according to the power station design document to obtain the target equipment quantity. The target photovoltaic equipment density can be obtained by dividing the target equipment quantity by the area of the target region.
[0092] Furthermore, a second adjustment coefficient corresponding to the target photovoltaic equipment density can be determined. Similarly, a preset mapping relationship between photovoltaic equipment density and adjustment coefficient can be stored in advance, and the second adjustment coefficient corresponding to the target photovoltaic equipment density can be determined based on this mapping relationship. The values of both the first and second adjustment coefficients can be in the range of -0.25 to 0.25. Then, the reference slope sensitivity coefficient can be adjusted according to the first adjustment coefficient, as follows: Preset slope sensitivity coefficient = Reference slope sensitivity coefficient × (1 + First adjustment coefficient); Based on the above formula, the preset slope sensitivity coefficient can be obtained; then, the reference slope aspect sensitivity coefficient can be adjusted according to the second adjustment coefficient, as follows: Preset aspect sensitivity coefficient = reference aspect sensitivity coefficient × (1 + second adjustment coefficient); Based on the above formula, the preset aspect sensitivity coefficient can be obtained.
[0093] In this way, by adjusting the reference slope sensitivity coefficient through the first adjustment coefficient corresponding to the lightning deviation, the guiding effect of the slope on the thundercloud is quantified and dynamically adjusted according to the actual lightning risk (deviation) of the site to match the strength characteristics of lightning activity. In addition, the reference slope sensitivity coefficient is adjusted by a second adjustment coefficient corresponding to the equipment density, so that the compatibility between the slope and the direction of thunderclouds is quantified and adjusted according to the density of equipment to ensure that the protection range prioritizes coverage of high-value equipment areas.
[0094] S307. Adjust the preset installation position according to the direction of the target evolution trend and the target deviation value to obtain the target installation position.
[0095] In this embodiment, the preset installation position can be moved along the direction of the target evolution trend by a target deviation value, thereby obtaining the target installation position.
[0096] Please see Figure 6 , Figure 6This is a schematic diagram of a PLP installation position change provided in an embodiment of this application. It can be seen that the PLP in the dashed line style is in the preset installation position (the initially planned slope peak position); the PLP in the solid line style is in the target installation position (the adjusted final position). Indicates the deviation from the target value. Indicates slope, Figure 6 The arrow in the image points in the direction of the target's evolution trend. Originally, the PLP was set in the preset installation position, but in order to shift the center of gravity of its protection range towards the "high-risk area of thundercloud evolution," it needs to be moved along the direction of the target's evolution trend. The distance to the target installation location, combined with the terrain slope. This ensures that the adjusted PLP can more accurately cover the lightning risk area of the site and improve the lightning protection effect.
[0097] To illustrate, Example 1 is as follows: The target photovoltaic power station is a photovoltaic power station in a high-altitude mountainous area, and measurements were taken to obtain... The slope is 205°, with an average gradient of 205°. 25°, slope to the southeast At 155°, the target ground flash density 7 times / (km) 2 a) Maximum peak ground flashover current The target PLP is installed at a height of 25kA at the top of the slope. It is 30m; Calculating the initial protection radius using the rolling ball method Substitute the above data into the first preset calculation formula:
[0098] Standard rolling ball radius Taking 45m as an example, according to the first preset calculation formula, the following can be calculated: It is 42.43m; Next, the above data can be substituted into the second preset calculation formula:
[0099] Among them, the first included angle (degrees), preset slope sensitivity coefficient The preset aspect sensitivity coefficient is 0.15. The value is 0.1; according to the second preset calculation formula, the terrain factor coefficient can be calculated. Approximately 1.1387; Then, the above data can be substituted into the fifth preset calculation formula:
[0100] Among them, the reference current The value is 30kA; the lightning activity index is calculated according to the fifth preset calculation formula. It is 5.83; Furthermore, the above calculations are obtained... , , Substitute into the third preset calculation formula:

[0102] Based on the fourth preset calculation formula mentioned above, the target deviation value can be obtained. The target PLP is moved 23.90m from the preset installation position (top of the slope) towards the direction of the target's evolution trend, so that the center of gravity of the protection range is biased towards the high-risk area of lightning strikes, thus obtaining the optimal installation position of the target PLP (target installation position).
[0103] Example 2: The target photovoltaic power station is a photovoltaic power station in a high-altitude area, as measured... The slope is 277°, with an average gradient of 277°. 15°, slope to the southwest At 240°, the target ground flash density 3 times / (km) 2 a) Maximum peak ground flashover current The target PLP is installed at a height of 20kA at the top of the slope. 25m; standard rolling ball radius A slope sensitivity coefficient can be set to 45m; The preset aspect sensitivity coefficient is 0.15. The first included angle is 0.1. (degrees); reference current 30kA; Lightning weighting coefficient It is 0.05; Can , Substituting into the first preset calculation formula, we can calculate... It is 40.31m; then, it can be... , , Substituting these values into the second preset calculation formula, the terrain factor coefficients are calculated. It is 1.12326; Next, you can also... , , Substituting into the fifth preset calculation formula, the lightning activity index is calculated. It is 2; Furthermore, it can be , , Substituting the values into the third preset calculation formula, the target protection radius is obtained. It is 49.81m; Finally, you can , Substituting the values into the fourth preset calculation formula, the target deviation value is obtained. The target PLP is moved 14.99m from the preset installation position towards the direction of the target's evolution trend, so that the center of gravity of the protection range is biased towards the high-risk area of lightning strikes, thus obtaining the target installation position.
[0104] It should be explained that Examples 1 and 2 are merely illustrative examples. In specific applications, more precise calculations can be performed based on actual protection requirements, and no limitations are imposed here.
[0105] In summary, the method for determining the PLP installation location of a photovoltaic power station described in this application solves the problem of "ignoring environmental differences" in existing technologies by acquiring target terrain data and lightning activity data of the target area, ensuring that the installation location is adapted to the terrain features and conforms to the lightning distribution pattern. Next, by combining the target terrain factors and the lightning activity dataset, the target evolution trend direction (the direction dominated by thunderclouds) is determined, ensuring that the installation location is accurately aligned with the direction of high lightning incidence, avoiding blind spots in protection. Then, by combining the basic information of the PLP equipment, the target deviation value is calculated to achieve a quantitative match between equipment capabilities and environmental requirements, rather than blindly selecting a site. Finally, based on the target evolution trend direction and the target deviation value, the preset location is adjusted so that the installation location simultaneously meets the three core requirements of "adapting to the terrain, aligning with the direction dominated by lightning, and matching the PLP protection effectiveness," thereby determining a suitable installation location for the PLP.
