[0055] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0056] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.
[0057] like Figure 1 As shown, a method for determining an integrated circuit of a photovoltaic power station provided by an embodiment of the present invention includes:
[0058] Step S110, obtaining the scope of the photovoltaic power station area and the device location of each photovoltaic device.
[0059] Specifically, a drawing of a photovoltaic power station area can be obtained in advance, and the scope of the photovoltaic power station area and the equipment location of each photovoltaic device can be determined on the drawing. The drawing can be a plan layout or topographic map of the photovoltaic power station area, and the photovoltaic devices include a box transformer and a booster station. The method for determining the scope of the photovoltaic power station area and the equipment location is not limited here. In response to the user's operation instructions, the regional scope of the photovoltaic power station area and the equipment location of each photovoltaic device can be circled on the drawing, or the existing regional detection algorithm and target detection algorithm can be used to determine the regional scope of the photovoltaic power station area on the drawing and the location of the photovoltaic equipment on the drawing.
[0060] It should be noted that the contour lines of the photovoltaic power station area are drawn on the drawings, and the form of the drawings is not limited, and can be CAD drawings and SketchUp drawings, etc. The complex terrain area refers to an area with a mixture of multiple terrains.
[0061] Step S120, performing slope partitioning on the photovoltaic power station area to obtain at least one slope area.
[0062] It should be noted that the specific method for slope zoning of the photovoltaic power station site is not limited here. For example, a GIS (Geographic Information System) drawing can be generated based on the topographic map, and the slope analysis can be performed through ArcGIS and other software, and then the various slope areas can be determined based on the analysis results. The slope of each location in the photovoltaic power station site can also be determined first, for example, through on-site measurement, and then the photovoltaic power station site is divided into zones according to the slope of each location to obtain various slope areas.
[0063] Step S130, for any two of the photovoltaic devices, determine the number of slope areas passed by the line segments connecting the two photovoltaic devices based on the device positions, determine the routing method between the two photovoltaic devices based on the number of slope areas passed based on preset rules, generate the cable path with the lowest cost between the two photovoltaic devices based on the routing method, and calculate the cable cost between the two photovoltaic devices based on the cable path.
[0064] Specifically, two photovoltaic devices can be connected, and the number of slope areas passed by the connection line is determined. The routing method between the two photovoltaic devices is automatically selected according to the number of slope areas passed. The routing method with the lowest cost corresponds to the cable path with the lowest cost. For example, when the number of slope areas passed is large, it means that the terrain slope between the two photovoltaic devices varies a lot, and there may be depressions or hillsides (which may require the construction of bridges, etc.). At this time, it is not suitable to route along the bracket gap between the two photovoltaic devices. You can choose to route along the road closest to the photovoltaic device in the photovoltaic power station area. The preset rules can be set by the user in advance according to the actual situation, and are not limited to the above-mentioned methods. Routing methods include routing along the road, routing along the bracket gap, and Manhattan routing.
[0065] The cable path between two PV devices is generated according to the routing method. For example, when routing along a road, the road between the mapping points corresponding to the two PV devices is the cable path. The mapping point is the point on the road where the PV device is mapped to the nearest point. The cable length can be determined according to the cable path. The corresponding cable cost can be obtained by multiplying the cable length by the corresponding cable unit price.
[0066] Step S140 , performing path optimization among all the photovoltaic devices based on the cable cost, and determining the integrated line path with the lowest cost in the photovoltaic power station area.
[0067] Specifically, the existing path optimization algorithm can be used to search for the best path among all photovoltaic devices, where the cable path connecting all photovoltaic devices with the lowest cost is the integrated line path of the photovoltaic power station area. The path optimization algorithm includes the minimum spanning tree algorithm and the graph theory algorithm, etc., which are not limited here.
[0068] In this embodiment, drawings such as topographic maps of the photovoltaic power station area can be obtained in advance, and the scope of the photovoltaic power station area and the equipment location of each photovoltaic device can be determined on the drawings. The photovoltaic device may include a box transformer and a booster station. The photovoltaic power station area is partitioned by slope, and at least one slope area is obtained to determine the terrain conditions of each area in the photovoltaic power station area. For any two photovoltaic devices, the terrain conditions between the two photovoltaic devices are judged according to the number of slope areas passed by the connection between the two photovoltaic devices, and the routing method that is most suitable for the terrain between the two photovoltaic devices is automatically determined in combination with the preset rules and the terrain conditions, and then the cable path with the lowest cost between the two photovoltaic devices is generated, which improves the adaptability and pertinence of the generated cable path to the terrain and reduces the cable cost between the two photovoltaic devices. According to the cable cost between each two photovoltaic devices, the path optimization is performed between all photovoltaic devices to determine the cable path that connects all photovoltaic devices and has the lowest total cost. The cable path is the integrated line path. The technical solution of the present invention can automatically select a suitable routing method with the lowest cost according to the terrain conditions, and determine the cable path with the lowest total cost according to the cable cost between each two photovoltaic devices, which can reduce the cable cost of the integrated line in complex terrain and improve the adaptability to complex terrain.
[0069] Optionally, the performing slope partitioning on the photovoltaic power station area includes:
[0070] The photovoltaic power station area is divided into grids to obtain a plurality of first grids.
[0071] Specifically, the first grid can be a square grid, and the side length of the square grid is set according to actual conditions and can be as small as possible to avoid dividing areas with different contour lines into the same grid, resulting in multiple areas with different slopes in the same grid, thereby affecting the calculation accuracy of the subsequent slope angle in the first grid.
[0072] Contour lines of the photovoltaic power station area are obtained, and the slope angles in each of the first grids are determined according to the contour lines.
[0073] Specifically, the method for calculating the slope angle is not limited here. For example, the elevation of the highest point and the elevation of the lowest point in the first grid can be determined based on the contour lines, the elevation difference can be determined based on the elevation of the highest point and the elevation of the lowest point, and the horizontal distance between the highest point and the lowest point can be determined. The slope angle in the first grid is determined based on the elevation difference and the horizontal distance, and the slope angle α = arctan (elevation difference / horizontal distance).
[0074] The elevation difference between two relative boundaries in the first grid can also be determined, and then the slope angle can be determined. For example, the first average elevation of all points on the left boundary of the first grid and the second average elevation of all points on the right boundary can be determined. The absolute value of the difference between the first average elevation and the second average elevation is the first elevation difference between the left boundary and the right boundary. The second elevation difference between the upper boundary and the lower boundary can also be determined in the same way. Then, the maximum elevation difference between the first elevation difference and the second elevation difference is selected as the elevation difference of the first grid. The side length of the first grid (multiplied by the scale) is used as the horizontal distance, and the slope angle of the first grid is determined according to the elevation difference and the horizontal distance.
[0075] The photovoltaic power station area is partitioned according to the slope angle to obtain at least one slope area, wherein the first grids whose slope angles are in the same angle range and interconnected are one slope area.
[0076] Specifically, the slope angle can be divided into multiple continuous angle ranges from zero to 90 degrees, and the first grids with slope angles in the same angle range and interconnected with each other are regarded as a slope area, so as to divide the photovoltaic power station area into at least one slope area. Figure 3 The photovoltaic power plant site shown has three slope areas.
[0077] It should be noted that due to the influence of the terrain in different grids, the slope angles in two adjacent first grids may fluctuate to a certain extent, so that the slope angles between adjacent first grids will not be exactly the same. For example, a small shallow pit or a small earth slope will affect the slope angle in the grid. Therefore, treating the first grids with slope angles within the same angle range and interconnected with each other as a slope area can improve processing efficiency compared to treating the first grids with the same slope angle as a slope area, and at the same time will not affect the path planning of the integrated line.
[0078] In this optional embodiment, the photovoltaic power station area is partitioned by slope, which facilitates the automatic selection of a suitable routing method according to the terrain conditions, thereby improving the refinement and adaptability of the integrated line path planning and saving cable costs.
[0079] Optionally, determining the routing mode between two photovoltaic devices according to the number of slope areas passed based on a preset rule includes:
[0080] comparing the number of times the slope area is passed with a preset threshold;
[0081] If the number of the slope areas is less than the preset threshold, the wiring between the two photovoltaic devices is arranged along the gap between the brackets;
[0082] If the number of the slope areas passed is greater than or equal to the preset threshold, the route between the two photovoltaic devices is along the road route.
[0083] Specifically, the number of slope areas passed by the connection between the two photovoltaic devices is compared with a preset threshold. The preset threshold can be preferably 3. When the number of slope areas passed is less than the preset threshold, it means that the terrain slope change between the two photovoltaic devices is small, and the routing method along the bracket gap can be adopted, which can reduce the integrated line length and save cable costs; when the number of slope areas passed is greater than or equal to the preset threshold, it means that the terrain slope change between the two photovoltaic devices is large, and there may be depressions and hillsides. If the routing method along the bracket gap is adopted, wiring is inconvenient, and it may also be necessary to add a bridge frame, etc. Therefore, the routing method along the road can be directly adopted to improve the convenience of wiring.
[0084] In this optional embodiment, the terrain conditions between the two photovoltaic devices can be roughly determined based on the number of slope areas passed by the connection line between the two photovoltaic devices, and then the appropriate routing method can be automatically selected according to the terrain conditions, so that an integrated line in the photovoltaic power station area may have multiple routing methods. Compared with the single routing method in the prior art, the refinement and adaptability of the integrated line path planning are improved, and the cable cost can be further reduced.
[0085] Optionally, generating a cable path with the lowest cost between two photovoltaic devices according to the routing method includes:
[0086] When the routing mode is along a road, the two photovoltaic devices are respectively mapped onto the roads in the photovoltaic power station area to obtain mapping points of the photovoltaic devices on the roads.
[0087] Specifically, when the route along the road is chosen, the road between the two photovoltaic devices is the only path. The photovoltaic device is mapped to the road closest to the photovoltaic device according to the location of the photovoltaic device, or mapped to the road closest to the line between the two photovoltaic devices, wherein the mapping point is on the closest road. When the route along the road is chosen, the cable length between the photovoltaic device and the road can be reduced, saving cable costs. The line between the location of the photovoltaic device and the location of the mapping point is perpendicular to the road. If the road is a curve, it is perpendicular to the tangent at the mapping point on the road.
[0088] The road between the two mapping points is determined to be the shortest path between the two photovoltaic devices.
[0089] In this optional embodiment, when the terrain between two photovoltaic devices is not suitable for wiring, the wiring is routed along the road. When the wiring is routed along the road, the wiring is convenient, simple and efficient.
[0090] Optionally, generating a cable path with the lowest cost between two photovoltaic devices according to the routing method includes:
[0091] When the routing method is routing along the bracket gaps, the row spacing between the brackets in each row and the column spacing between the brackets in the photovoltaic power station area are obtained.
[0092] It should be noted that since the horizontal coordinates of each row of brackets or the vertical coordinates of each column of brackets in the bracket array are not exactly the same and there will be certain fluctuations, the brackets with horizontal coordinates or vertical coordinates within a certain range can be regarded as brackets in the same row or column.
[0093] A mode of row spacings among all the row spacings and a mode of column spacings among all the column spacings are determined.
[0094] Specifically, the row spacing that appears most frequently among all row spacings of the bracket array is the row spacing mode, and the column spacing that appears most frequently among all column spacings is the column spacing mode.
[0095] The bracket array is divided according to the mode of the row spacing and the mode of the column spacing, and the gap discrete points in the bracket array that can be used for routing the integrated circuit are determined according to the division results.
[0096] Specifically, the bracket array may be divided by a grid division method or a point-scattering density division method to determine the gap discrete points between the brackets that can be used for routing integrated circuits.
[0097] A path planning algorithm is used to determine a first cable path between two photovoltaic devices in all the gap discrete points.
[0098] Specifically, the path planning algorithm may include an optimization algorithm such as a minimum spanning tree algorithm and a graph theory algorithm, and finds the shortest path between the two photovoltaic devices between all gap discrete points, and the shortest path is the first cable path. Usually, the length of the cable along the bracket gap between the two photovoltaic devices is shorter than the length of the cable along the road, so the shortest path among all gap discrete points can be directly used as the cable path between the two photovoltaic devices.
[0099] For example, Figure 3 As shown, there are two cable paths between box transformer 1 and box transformer 2. In order to reduce the cable cost, the lengths of the cable paths are compared, and finally the shortest cable path is determined to be the first cable path. It should be noted that the present invention assumes that no additional facilities such as bridges are required to be set up when crossing two or less slope areas, so the cable cost is mainly related to the cable length.
[0100] In this optional embodiment, when the routing method along the bracket gap is adopted, firstly, the gap discrete points in the bracket gap that can be used for the integrated circuit routing are determined, and then the first cable path between the two photovoltaic devices is determined among all the gap discrete points. When the terrain between the two photovoltaic devices is suitable for the routing method along the bracket gap, the routing method along the bracket gap can reduce the cable length between the two photovoltaic devices and save the cable cost.
[0101] Optionally, dividing the bracket array according to the row spacing mode and the column spacing mode, and determining the gap discrete points in the bracket array that can be used for routing the integrated circuit according to the dividing result includes:
[0102] Dividing the bracket array into grids to obtain a plurality of second grids, wherein the width of the second grid is determined by the mode of the row spacing, and the length of the second grid is determined by the mode of the column spacing;
[0103] In all the second grids, an area outside the bracket is determined as a traversable area for routing the integrated circuit, and a plurality of the gap discrete points are determined in the traversable area.
[0104] Specifically, all points in the walkable area can be used as gap discrete points, and the grid segmentation method can be used to determine the gap discrete points between the brackets. The row width of the second grid = the mode of row spacing + X, and the column width of the second grid = the mode of column spacing + Y, where X and Y are preset positive integers. In addition to using the center point of the second grid that does not include the bracket as the gap discrete point, the center point of the gap between the front and rear rows of the bracket can also be used as the gap discrete point.
[0105] For example, Figure 2 As shown, the bracket array is grid-cut, and then the gap discrete points available for integrated circuit routing are determined based on the cutting results, where the area on the drawing that does not include the bracket is a routeable area for an integrated circuit. Figure 2 The middle dotted area is the walkable area of the integrated circuit. In order to facilitate the determination of gap discrete points and improve efficiency, the center points of each second grid in the walkable area can be used as discrete gap points, or the gap center points of adjacent brackets in the walkable area can be used as gap discrete points.
[0106] In this optional embodiment, the walkable area between each bracket for integrated circuit routing is determined by grid segmentation, and then the gap discrete points are determined in the walkable area. This is simple and efficient, and can quickly determine the gap discrete points for routing in the bracket array.
[0107] Optionally, dividing the bracket array according to the row spacing mode and the column spacing mode, and determining the gap discrete points in the bracket array that can be used for routing the integrated circuit according to the dividing result includes:
[0108] Evenly scattering points in the bracket array, wherein a plurality of points are arranged in an array, wherein the row spacing of the array is determined by the mode of the row spacing, and the column spacing of the array is determined by the mode of the column spacing;
[0109] The gap discrete points are determined among points not on the support.
[0110] Specifically, a plurality of points arranged in an array are set in the bracket array, the row spacing of each row point in the point array = the row spacing mode + X, and the column spacing of each column point in the point array = the column spacing mode + Y, wherein X and Y are preset positive integers.
[0111] It should be noted that if a path connecting the two photovoltaic devices cannot be determined among all the traversable gap discrete points, a routing method along the road is adopted. In this case, the road between the mapping points of the two photovoltaic devices on the road is the only path.
[0112] In this optional embodiment, points are directly scattered in the bracket array, and then gap discrete points are determined among all the scattered points, which eliminates the step of dividing the walkable area and further improves the efficiency of determining gap discrete points.
[0113] Optionally, after determining the first cable path between the two photovoltaic devices in all the gap discrete points using a path planning algorithm, the method further includes:
[0114] generating a second cable path between the two photovoltaic devices according to a routing method along the road, and comparing the length of the first cable path with the length of the second cable path;
[0115] According to the comparison result, the shortest path between the first cable path and the second cable path is determined to be the cable path between the two photovoltaic devices.
[0116] Specifically, since the first cable path along the bracket gap is not the only path between the two photovoltaic devices, the cables between the two photovoltaic devices can also be routed along the road. Although the cable length along the bracket gap between the two photovoltaic devices is usually shorter than the cable length along the road, in order to ensure the lowest cable cost between the two photovoltaic devices, the length of the first cable path along the bracket gap and the length of the second cable path along the road are compared. Based on the comparison results, the shortest path of the two paths is selected as the cable path between the two photovoltaic devices, thereby ensuring that the cable length between the two photovoltaic devices is the shortest, saving cable costs.
[0117] Optionally, calculating the cable cost between the two photovoltaic devices according to the cable path includes:
[0118] Determine the cable length between the two photovoltaic devices according to the cable path, and determine the corresponding cable specifications and cable unit prices in a preset corresponding relationship according to the specifications and models of the two photovoltaic devices;
[0119] The cable cost between the two photovoltaic devices is calculated according to the cable length and the cable unit price.
[0120] Specifically, for any two photovoltaic devices i and j, assuming that the cable length between the two photovoltaic devices is L(ij), the specification model of the cable used between the two is determined in the preset corresponding relationship to be W, and the cable unit price corresponding to cable W is P(W). The corresponding relationship includes a one-to-one corresponding photovoltaic device group (two photovoltaic devices), cable specification model and cable unit price, then the cable cost between the two photovoltaic devices i and j is P=L(ij)×P(W).
[0121] Optionally, the photovoltaic equipment includes a booster station and a box transformer, and performing path optimization among all the photovoltaic equipment based on the cable cost to determine the integrated line path with the lowest cost in the photovoltaic power station area includes:
[0122] The booster station is used as a root node and each of the box transformers is used as a child node to establish a network topology of the photovoltaic device, wherein the network topology includes multiple paths connecting the booster station and each of the box transformers;
[0123] Each path in the network topology is traversed, and a path with the lowest total cost in the network topology is determined as the integrated line path according to the cable cost between each two photovoltaic devices.
[0124] Specifically, for each path in the network topology, the cable costs between each two adjacent photovoltaic devices determined in the previous article are added to obtain the total cost of each path, and the path with the lowest total cost is selected as the integrated line path, where the integrated line path can be determined by the minimum spanning tree algorithm.

Compared with manually selecting the routing method based on personal experience and then planning the integrated line path, the solution of this embodiment automatically selects the appropriate routing method according to the terrain through computers and other processing equipment, and has stronger adaptability to the terrain of the photovoltaic power station site and higher efficiency.
