Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a partitioning method and system for photovoltaic brackets in irregular areas and a photovoltaic bracket array. Background Art

[0002] In large-scale ground power station projects, the wind loads on photovoltaic flat single-axis trackers located in different areas of the project, such as corners, periphery, inner periphery, and deep inner periphery, vary greatly. If they are designed according to one load, the tracker bracket materials in the large areas of the inner periphery and deep inner periphery will be redundant, increasing costs. The bracket materials in the outer periphery and corner areas are not sufficient to withstand the corresponding wind loads, posing a hidden danger to project safety.

[0003] At present, by combining wind tunnel test data to divide the inner and outer areas, all trackers in a project can be divided into different areas according to their locations, and the tracking brackets can be designed separately according to the load conditions in different areas, so that the project can reduce costs as much as possible while ensuring safety; however, there is currently no applicable method in the industry for zoning the photovoltaic bracket array within the irregular red line area.

[0070] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0071] According to the first embodiment provided by the present invention, Figure 1 As shown, a zoning method for photovoltaic brackets in irregular areas includes:

[0072] S100 obtains the coordinates of all boundary lines of the irregular region, and draws the minimum circumscribed rectangular frame of the irregular region according to the coordinates of the boundary lines;

[0073] Specifically, Figure 2 As shown, for projects with irregular areas, the boundary line of the area is drawn along the project topographic map by drawing polylines, and all coordinate points (X, Y) of the polylines constituting the boundary line are obtained, where X represents the east-west position coordinate and Y represents the north-south position coordinate. The irregular area in this embodiment refers to all areas except regular areas such as squares, rectangles, rhombuses, triangles, and regular polygons.

[0074] Compare all the coordinate points that make up the boundary line of the irregular region to obtain the outermost points in the four directions of top, bottom, left and right. Based on these four outermost points, the minimum circumscribed rectangular frame of the irregular region can be obtained, such as Figure 3 As shown, the minimum circumscribed rectangular frame EFGH is the minimum rectangular frame covering the entire irregular area.

[0075] S200 presets the area occupied by each photovoltaic bracket in the minimum circumscribed rectangular frame according to project requirements, marks it as a preset photovoltaic bracket area, and forms a preset photovoltaic bracket area array;

[0076] Specifically, after obtaining the minimum bounding rectangle, Figure 4 As shown, the overall photovoltaic bracket array is arranged within the minimum circumscribed rectangular frame according to the length, width and spacing requirements of the photovoltaic bracket determined by the project, and a diagram after the entire minimum circumscribed rectangular frame is obtained to form a preset photovoltaic bracket area array. Here, the area of ​​a single photovoltaic bracket within the minimum circumscribed rectangular frame is the projection area of ​​the photovoltaic bracket to the ground. The projection shape of the photovoltaic bracket is a rectangle, and multiple rectangles are arranged at a certain spacing to cover the entire minimum circumscribed rectangular frame.

[0077] S300 determines whether each preset photovoltaic support area is an available position one by one, and if so, arranges a photovoltaic support in this area, and if not, does not arrange a photovoltaic support in this area, so as to form a photovoltaic support array in the irregular area;

[0078] Specifically, determine whether each preset photovoltaic bracket area is an available location one by one. An available location refers to a location where a photovoltaic bracket can be arranged when the project is actually implemented, and an unavailable location refers to a location where a photovoltaic bracket cannot be arranged when the project is actually implemented. For example, when the edge of the preset photovoltaic bracket area intersects with the boundary of an irregular area, the preset photovoltaic bracket area is an unavailable location, or when the corner point of the preset photovoltaic bracket area is outside the irregular area, the preset photovoltaic bracket area is an unavailable location. Mark each available location, and the marked image is as follows Figure 5 As shown, Figure 5 The light grey area is the layout of all available positions.

[0079] S400 counts the number of photovoltaic brackets included in the photovoltaic bracket array;

[0080] Specifically, the number of photovoltaic brackets in an irregular area refers to the number of available positions in the irregular area. When counting the number of photovoltaic brackets in an irregular area, the counting can be performed row by row. For example, the number of available positions can be counted one by one from the first photovoltaic bracket in the first row to the right, and then the number of available positions can be counted one by one from the first photovoltaic bracket in the second row to the right, and so on, to count the number of all available positions in the irregular area.

[0081] S500 divides all photovoltaic support arrays into peripheral areas and non-peripheral areas.

[0082] Specifically, for the photovoltaic tracking system, reasonable and compliant wind tunnel tests must be conducted. By conducting wind tunnel tests on photovoltaic brackets, the division rules of the peripheral area and the non-peripheral area in the photovoltaic tracking system can be determined. The division rules of the peripheral area and the non-peripheral area and the number of all photovoltaic brackets in the irregular area can be used to determine whether each available position (photovoltaic bracket) belongs to the peripheral area or the non-peripheral area. For example, multiple rows of photovoltaic brackets in the east direction are determined as the peripheral area, and the area within the peripheral area is determined as the non-peripheral area. After determining the area to which each available position belongs, the following can be obtained: Figure 6 The final layout diagram is shown. After obtaining the area to which each photovoltaic bracket in the irregular area belongs, the photovoltaic bracket can be independently designed according to the different load combinations in each area, so that the project can reduce costs as much as possible while ensuring safety.

[0083] The load combination of each area includes the total wind load W, snow load S and deadweight D. The principle of combined design is to make comprehensive selections based on the terrain, climate and customer requirements of the location of the photovoltaic bracket array. In the photovoltaic bracket array, the load combinations in the outer area and the inner area are different, so the performance required of the load-bearing components of the photovoltaic bracket is also different. Independent design of the photovoltaic bracket according to the different load combinations in each area can ensure that the photovoltaic bracket is sufficient to withstand the corresponding wind load and reduce costs as much as possible.

[0084] Further, S300 determines whether each preset photovoltaic support area is an available position one by one, specifically including:

[0085] S310 marks a photovoltaic support area in the preset photovoltaic support area that does not intersect with the boundary of the irregular region and is located in the irregular region as an available position.

[0086] Specifically, determine whether all photovoltaic brackets within the minimum circumscribed rectangular frame intersect with the boundary of the irregular area and whether all corner points of the photovoltaic bracket are located within the irregular area. If more than one side of the photovoltaic bracket intersects with the boundary of the irregular area or more than one corner point of the photovoltaic bracket is located outside the irregular area, the position of the photovoltaic bracket is an unusable position; if all sides of a photovoltaic bracket do not intersect with the boundary of the irregular area and all corner points of the photovoltaic bracket are located within the irregular area, the position of the photovoltaic bracket is an available position, and the available position is marked.

[0087] Wherein, S310 marks the photovoltaic support area in the preset photovoltaic support area that does not intersect with the boundary of the irregular region and is located in the irregular region as an available position, specifically including:

[0088] S311 determines whether the edge of the preset photovoltaic support area intersects with the boundary of the irregular area;

[0089] S312: if any edge of the preset photovoltaic support area intersects with the boundary of the irregular region, the preset photovoltaic support area is marked as an unusable location;

[0090] S313: If all sides of the preset photovoltaic support area do not intersect with the boundary of the irregular region, determining whether a corner point of the preset photovoltaic support area is within the irregular region;

[0091] S314 If all corner points of the preset photovoltaic support area are within the irregular area, the preset photovoltaic support area is marked as an available position; if any corner point of the preset photovoltaic support area is outside the irregular area, the preset photovoltaic support area is marked as an unavailable position.

[0092] Specifically, when judging whether each preset photovoltaic bracket area is an available position, you can first judge whether one edge of the photovoltaic bracket intersects with the boundary of the irregular area. If they intersect, you can directly judge that the location of the photovoltaic bracket is an unusable position. If they do not intersect, continue to judge whether the other edges of the photovoltaic bracket intersect with the boundary of the irregular area. If they do not intersect, continue to judge whether the corner point of the photovoltaic bracket is located in the irregular area.

[0093] When judging whether the corner points of the photovoltaic bracket are located in the irregular area, the judgment is also performed one by one. If a corner point of the photovoltaic bracket is located outside the irregular area, the position of the photovoltaic bracket is directly judged as an unusable position. Only when all the corner points of the photovoltaic bracket are located in the irregular area can it be judged as an available position.

[0094] As a variation, it is also possible to first determine whether the corner points of the photovoltaic support are located in the irregular area. If they are all located in the irregular area, it is further determined whether the edge of the photovoltaic support intersects with the boundary of the irregular area.

[0095] Further, S311 determines whether the edge of the preset photovoltaic support area intersects with the boundary of the irregular area, specifically including:

[0096] S3111 obtains an edge of a preset photovoltaic support area and defines it as a first line segment;

[0097] S3112 obtains an edge of the irregular region boundary and defines it as a second line segment;

[0098] S3113 determines whether the X-axis coordinate of the endpoint with a larger X-axis coordinate in one line segment is smaller than the X-axis coordinate of the endpoint with a smaller X-axis coordinate in another line segment or whether the Y-axis coordinate of the endpoint with a larger Y-axis coordinate in one line segment is smaller than the Y-axis coordinate of the endpoint with a smaller Y-axis coordinate in another line segment;

[0099] S3114: If yes, determine that the first line segment does not intersect with the second line segment;

[0100] If S3115 is no, then take the starting point of the first line segment and the starting point of the second line segment to form a third line segment, take the end point of the first line segment and the starting point of the second line segment to form a fourth line segment, calculate the cross product result of the second line segment and the third line segment and the cross product result of the second line segment and the fourth line segment, if the two cross product results are of different signs, then it is determined that the first line segment and the second line segment intersect, otherwise, it is determined that the first line segment and the second line segment do not intersect.

[0101] Specifically, Figure 7As shown, take one side of the photovoltaic bracket, take the line segment AB from the start point to the end point of this side, take a line segment CD in the irregular regional boundary line, first determine whether the X-axis and Y-axis of the two line segments have overlapping points, that is, determine whether the endpoint with a larger X coordinate in the two line segments is smaller than the endpoint with a smaller X coordinate in the other line segment. If it is smaller, the two line segments must not intersect, otherwise they may intersect. For example, in line segment AB, the coordinates of endpoint A are (2, 2), and the coordinates of endpoint B are (4, 4). In line segment CD, the coordinates of endpoint C are (1, 3), and the coordinates of endpoint D are (5, 1); the endpoint with a larger X coordinate in line segment AB is endpoint B, and the endpoint with a smaller X coordinate in line segment CD is C, and the X-axis coordinate of endpoint B is 4, which is greater than the X-axis coordinate of endpoint C, which is 1. Therefore, line segment AB and line segment CD may intersect.

[0102] If the coordinates of endpoint A are (1, 4), the coordinates of endpoint B are (4, 6), the coordinates of endpoint C are (2, 1), and the coordinates of endpoint D are (3, 3); the Y-axis coordinate 3 of endpoint D with a larger Y-axis coordinate in line segment CD is smaller than the Y-axis coordinate 4 of endpoint A with a smaller Y-axis coordinate in line segment AB, therefore, AB and CD must not intersect.

[0103] If line segment AB and line segment CD may intersect, continue to calculate the product of the line segment cross products, take endpoint A in the first line segment AB and endpoint D in the second line segment CD to form line segment AD, take endpoint B in the endpoints of the first line segment AB and endpoint D in the second line segment CD to form line segment BD, calculate line segments AD×CD and BD×CD. If the two cross product results have different signs, it means that endpoint A and endpoint B are on both sides of CD respectively, and line segment AB intersects with line segment CD, that is, when AD×CD*BD×CD<0, then the first line segment intersects with the second line segment.

[0104] After determining that the first line segment does not intersect with the second line segment, this method is used to continue to determine whether other sides of the photovoltaic support intersect with the boundary of the irregular region.

[0105] Further, S313 determines whether the corner point of the preset photovoltaic support area is within the irregular region, specifically including:

[0106] S3131 draws a ray to the left and right from the first corner point of the preset photovoltaic support area to obtain a first ray and a second ray;

[0107] S3132: Counting the number of intersections between the first ray and the irregular region boundary to obtain a first number;

[0108] S3133: Counting the number of intersections between the second ray and the irregular region boundary to obtain a second number;

[0109] S3134: if the first number and the second number are odd numbers respectively, and it is determined that the first corner point is within the boundary of the irregular region;

[0110] S3135 If the first number and the second number are not all odd numbers, determine that the first corner point is outside the boundary of the irregular region.

[0111] Specifically, this embodiment uses the ray method to determine whether the corner point of the photovoltaic bracket is within the irregular area, such as Figure 8 As shown, take a corner point A of the photovoltaic bracket and draw a ray AB and AC to the left and right respectively, and use the method of determining whether the two line segments intersect in step S430 to confirm the number of intersections between the rays AB and AC and the irregular regional boundary, for example, Figure 8 As shown in the figure, the ray AB from point A to the left has one intersection a with the polygon, and the ray AC from point A to the right has three intersections b, c, and d with the polygon, both of which are odd numbers, indicating that point A is within the polygon boundary. For example, the ray DE from point D to the left has two intersections g and h with the polygon, and the ray DF from point D to the right has two intersections i and j with the polygon, both of which are not all odd numbers, indicating that point D is outside the polygon boundary. This method is used to determine whether the other corner points of the photovoltaic bracket are within the irregular area one by one, and mark them.

[0112] According to the second embodiment provided by the present invention, the difference between this embodiment and the first embodiment is that, after obtaining the coordinates of all boundary lines of the irregular region in S100 of the first embodiment, and drawing the minimum circumscribed rectangular frame of the irregular region according to the coordinates of the boundary lines, this embodiment further includes:

[0113] S150 obtains the boundary line coordinates of all obstacles in the irregular region, and draws a multi-segment line according to the boundary line coordinates of all obstacles to form an obstacle boundary;

[0114] S300 of determining whether each preset photovoltaic support area is an available position one by one specifically includes:

[0115] S350 marks a photovoltaic support area in the preset photovoltaic support area that does not intersect with the boundary of the irregular region and the boundary of the obstacle and is located within the irregular region and outside the obstacle as an available position.

[0116] Specifically, Figure 2 As shown in the figure, when there are buildings or river obstacles in the irregular area, photovoltaic brackets cannot be installed in the obstacles. Therefore, it is necessary to obtain Figure 2The coordinates of the obstacle boundary line in the irregular area are obtained, and during project design, the positions of the photovoltaic brackets that intersect with the obstacle boundary or whose corner points are located in the obstacle need to be marked as unusable positions; conversely, the positions of the photovoltaic brackets that do not intersect with the irregular area boundary and the obstacle boundary and whose corner points are located in the irregular area and outside the obstacle are marked as available positions.

[0117] In this embodiment, the method for determining whether the edge of the photovoltaic support intersects with the boundary of the obstacle is the same as the method for determining whether the edge of the photovoltaic support intersects with the boundary of the irregular area. The method for determining whether the corner point of the photovoltaic support is outside the obstacle is the same as the method for determining whether the corner point of the photovoltaic support is within the irregular area, and the ray method is also used for determination, which will not be repeated here.

[0118] S500 divides all photovoltaic support arrays into peripheral areas and non-peripheral areas, specifically including:

[0119] S510: Obtain wind tunnel test data to determine a division rule between the outer area and the inner area, wherein the division rule includes a ratio of photovoltaic brackets in the outer area to photovoltaic brackets in the inner area, and a maximum spacing between photovoltaic brackets;

[0120] S520 determines the number of photovoltaic brackets in the peripheral area and the number of photovoltaic brackets in the inner area according to the number of all available positions and the ratio of photovoltaic brackets in the peripheral area to photovoltaic brackets in the inner area;

[0121] S530 obtains the length of the obstacle along the east-west direction;

[0122] S540 determines the area to which each available position belongs based on the number of photovoltaic brackets in the outer area, the number of photovoltaic brackets in the inner area, the length of the obstacle in the east-west direction, and the maximum spacing between the photovoltaic brackets.

[0123] Specifically, when an irregular area contains obstacles, the division of the inner and outer areas in the irregular area needs to consider the length of the obstacle in the east-west direction. For example, when there are no obstacles, the center of the irregular area should be the inner area or the deep inner area. However, when there are obstacles in the center of the irregular area, the photovoltaic brackets will be separated by the obstacles. If the length of the obstacle in the east-west direction is greater than the maximum spacing of the photovoltaic brackets, then one or more rows of photovoltaic brackets outside the obstacle boundary are the outer area.

[0124] Among them, S540 determines that the area to which each available position belongs includes:

[0125] S541 When the length of the obstacle in the east-west direction is less than the maximum spacing of the photovoltaic supports, multiple rows of available positions inward along the due east direction and multiple rows of available positions inward along the due west direction of the irregular regional boundary are respectively determined as the peripheral area according to the number of photovoltaic supports in the peripheral area, the available positions inside the peripheral area are determined as the non-peripheral area, and the first row of available positions in the non-peripheral area in the north-south direction is determined as the inner area, and the other available positions in the non-peripheral area are determined as the deep inner area;

[0126] S542 When the length of the obstacle along the east-west direction is greater than the maximum spacing of the photovoltaic supports, based on the number of photovoltaic supports in the peripheral area, multiple rows of available positions along the east direction inward of the irregular area boundary, multiple rows of available positions along the west direction inward, multiple rows of available positions along the east direction outward of the obstacle boundary, and multiple rows of available positions along the west direction outward are determined as the peripheral area, the available positions inside the peripheral area are determined as the non-peripheral area, the first row of available positions in the non-peripheral area along the north-south direction is determined as the inner area, and the other available positions in the non-peripheral area are determined as the deep inner area; wherein, along the east direction inward refers to along the east direction into the irregular area, and along the west direction inward refers to along the west direction into the irregular area.

[0127] Specifically, if the length of the obstacle along the east-west direction is less than the maximum spacing of the photovoltaic brackets, the obstacle can be ignored when dividing the inner and outer areas. The left and right rows of photovoltaic brackets are determined as the outer area, and the photovoltaic brackets on the inner side of the outer area are determined as the non-peripheral area. If there is a row of photovoltaic brackets on the top of the non-peripheral area, it is judged as the deep inner area, otherwise it is the inner area.

[0128] If the length of the obstacle in the east-west direction is greater than the maximum spacing of the photovoltaic brackets, the rows of photovoltaic brackets around the obstacle need to be identified as the outer area when dividing the inner and outer areas.

[0129] For example, Fig. 9 As shown, Fig. 9 The dark area indicates the inner area, and the light area indicates the outer area. The maximum spacing between photovoltaic brackets is 13m. If the length of the obstacle along the east-west direction is greater than 13m, that is, the spacing between photovoltaic brackets on the left and right sides of the obstacle is greater than 13m, the photovoltaic brackets on the left and right sides of the obstacle are not protected by other photovoltaic brackets. Therefore, when determining the outer area, the multiple rows of photovoltaic brackets on the left and right sides of the obstacle need to be considered as the outer area. The zoning diagram is as follows: Fig. 9 As shown in the figure on the left; if the length of the obstacle along the east-west direction is less than 13m, the photovoltaic brackets on the left and right of the obstacle belong to the inner area, and the zoning diagram is as follows: Fig. 9 As shown in the figure on the right.

[0142] When the length of the obstacle along the east-west direction is greater than the maximum spacing of the photovoltaic supports, based on the number of photovoltaic supports in the peripheral area, multiple rows of available positions along the east direction inward of the irregular geographical boundary, multiple rows of available positions along the west direction inward, multiple rows of available positions along the east direction outward of the obstacle boundary, and multiple rows of available positions along the west direction outward are determined as the peripheral area, the available positions inside the peripheral area are determined as the non-peripheral area, the first row of available positions in the non-peripheral area along the north-south direction is determined as the inner area, and the other available positions in the non-peripheral area are determined as the deep inner area.
