s110, acquiring position information of a first equipment device and a second equipment device in the photovoltaic power station, and establishing a coordinate system by taking the position of the first equipment device as an origin to enable the second equipment devices to be distributed in the coordinate system.

The photovoltaic power station provided by the embodiment of the invention can be a centralized photovoltaic power station, a string type photovoltaic power station or other types of photovoltaic power stations. The centralized photovoltaic power station generally includes a combiner box, a centralized inverter, a box-type substation (hereinafter referred to as "box transformer substation") and other equipment, each combiner box is connected to a plurality of photovoltaic modules to ensure the orderly connection of the photovoltaic modules and realize a combiner function, and all the combiner boxes are connected to the box transformer substation through the centralized inverter to realize electric energy conversion. A centralized inverter and a box transformer substation in a centralized photovoltaic power station are generally designed in an integrated mode and are installed in the same container. The group string type photovoltaic power station generally comprises a group string type inverter, a box transformer substation and other equipment devices, wherein each group string type inverter is connected with a plurality of photovoltaic modules, all the group string type inverters are connected into the box transformer substation, or each group string type inverter is connected into the box transformer substation through a plurality of combiner boxes so as to realize electric energy conversion.

Referring to fig. 2, the first equipment device 10 and the second equipment device 20 in the present embodiment are both equipment devices in a photovoltaic power plant, including but not limited to inverters, combiner boxes, box transformers, and the like. Illustratively, the first equipment device 10 is a centralized inverter or an integrated box transformer, and the second equipment device 20 is a combiner box, so that the photovoltaic power station wiring method provided by the embodiment of the invention is suitable for wiring between the combiner box and the inverter in the centralized photovoltaic power station. Illustratively, the first equipment device 10 is a box transformer substation, and the second equipment device 20 is a string inverter or a combiner box, so that the photovoltaic power station wiring method provided by the embodiment of the invention is suitable for routing between the string inverter and the box transformer substation or between the combiner box and the box transformer substation in the string photovoltaic power station. It is understood that the first equipment device 10 and the second equipment device 20 may be other combinations of the above equipment devices, or may be other equipment devices in the photovoltaic power plant, and it is sufficient that the corresponding relationship of connecting a plurality of second equipment devices 20 to one first equipment device 10 is satisfied, so that the technical solution of the embodiment of the present invention can be applied to provide a wiring solution for the connection between a plurality of second equipment devices 20 and one first equipment device 10.

In the present embodiment and the following embodiments, a photovoltaic power station is taken as a centralized photovoltaic power station, the first equipment device 10 is a box transformer substation, and the second equipment device 20 is a combiner box. Specifically, position information of the first equipping apparatus 10 and the second equipping apparatus 20 is acquired, a rectangular coordinate system is established with the position 10 of the first equipping apparatus as an origin, and the second equipping apparatus 20 is distributed in the coordinate system to acquire coordinates of the second equipping apparatus 20 in the rectangular coordinate system.

And S120, dividing the coordinate system into a plurality of areas, and wiring the areas according to a preset wiring rule corresponding to each area so as to enable the second equipment device in each area to be connected to the first equipment device.

Referring to fig. 2, the coordinate system may be divided into four regions according to four quadrants of the rectangular coordinate system, and coordinates of each second equipment device in the corresponding region may be acquired. For example, different wiring rules can be preset according to the terrain of the photovoltaic power station, the distribution of the photovoltaic modules and the distribution of the second equipment devices, and wiring can be carried out on different areas. For example, the plurality of regions include a first preset region, and the photovoltaic modules in the first preset region are arranged to form a regular square matrix, so that the preset wiring rule corresponding to the first preset region may be manhattan distance type wiring. The manhattan distance is also called a city block distance, namely the sum of the distance of two points in a coordinate axis along the X-axis direction and the distance along the Y-axis direction, and accordingly, manhattan distance type wiring is performed according to a manhattan distance measuring path between the two points. The plurality of areas in the coordinate system may further include a second preset area, and the second preset area is an area in which the photovoltaic modules are irregularly arranged, so that the preset wiring rule corresponding to the second preset area may be Euclidean distance type wiring. The euclidean distance generally refers to the euclidean distance, i.e., the linear distance between two points in space, and accordingly, the euclidean distance wiring connects the two points by a linear routing.

Illustratively, the second equipping apparatuses in the respective areas are connected to each other by cables and the second equipping apparatus closest to the origin in the respective areas is connected to the origin by cables according to a preset wiring rule corresponding to each area, so that the second equipping apparatuses in each area are connected to the first equipping apparatus. Considering that cables between the combiner box and the box transformer substation need to walk a bridge or be buried, the cables are wired according to the characteristics of different areas in the coordinate system according to the corresponding preset wiring rules, the cable laying difficulty is reduced, the cables and the construction cost are saved, and the line loss can be reduced.

S130, when the wiring mode between the second equipment devices of the adjacent areas can be optimized, the wiring mode between the second equipment devices of the adjacent areas is optimized to enable the wiring distance to be shortest.

For example, after the wiring of each region is completed, whether the wiring manner between the second equipment devices of the adjacent regions can be optimized is judged. For example, whether an optimized space exists in a wiring manner between the second equipment device nearest to the adjacent region and the second equipment devices connected to the second equipment device in each region is determined, and if the length of the routing between the second equipment device nearest to the adjacent region and the second equipment device connected to the second equipment device in a certain region is greater than the distance between the second equipment device and the second equipment device nearest to the adjacent region, it is determined that the wiring manner between the second equipment device and the second equipment device nearest to the adjacent region can be optimized. When the wiring mode is optimized, the original wiring mode of the second equipment device and the second equipment device with the adjacent region closest to the second equipment device can be changed into a mode that the second equipment device and the adjacent region are connected with the coordinate shaft through the vertical wiring, and then the coordinate shaft is connected with the origin, so that the wiring length between the second equipment device and the origin is shortened, and the optimization of the wiring mode is realized.

According to the technical scheme of the embodiment of the invention, a coordinate system is established by taking the position of a first configuration device in a photovoltaic power station as an origin, second configuration devices are distributed in the coordinate system, the coordinate system is divided into a plurality of areas, the areas are firstly wired according to a preset wiring rule corresponding to each area, so that the second configuration device in each area is connected to the first configuration device, and then when the wiring mode between the second configuration devices in adjacent areas can be optimized, the wiring mode between the second configuration devices in the adjacent areas is optimized, so that the wiring distance is shortest. Compared with the traditional manual wiring design scheme, the technical scheme provided by the invention has wider application scenes, and can be suitable for wiring design between the junction box and the inverter in a centralized photovoltaic power station, and wiring design between the group string type inverter and the box transformer substation and between the junction box and the box transformer substation in a group string type photovoltaic power station. This scheme can realize the wiring fast according to the coordinate of being equipped with the device, is favorable to promoting wiring design efficiency, and the division of different regions in the photovoltaic power plant coordinate system for same power station can allow the wiring mode of multiple difference to exist, and the wiring mode is more nimble, in order to realize the rational design of different regional wirings, and the wiring optimization between the adjacent region helps shortening and walks line length, thereby reduces the cable loss, and practices thrift cable and construction cost.

On the basis of the above embodiment, the present embodiment further optimizes the above photovoltaic power station wiring method. Correspondingly, the method of the embodiment specifically includes:

s210, acquiring position information of a first equipment device and a second equipment device in the photovoltaic power station, and establishing a coordinate system by taking the position of the first equipment device as an origin to enable the second equipment devices to be distributed in the coordinate system.

S220, sorting the second equipment devices in the areas from far to near according to the distance between the second equipment devices in each area and the origin.

Fig. 3 is a schematic diagram of a distribution position of a equipped device in a coordinate system area according to an embodiment of the present invention, and fig. 3 schematically illustrates a distribution and routing connection of the equipped device in the coordinate system area shown in fig. 2. The present embodiment is still schematically illustrated by taking the photovoltaic power station as a centralized photovoltaic power station, the first equipment device is a box transformer substation, and the second equipment device is a combiner box, as shown in fig. 3, the first equipment device, i.e., the box transformer substation, is located at the origin of coordinates O, and the second equipment device, i.e., the combiner box is distributed in the area of the coordinate system, as shown by points A, B, C, D and E in the first quadrant. And calculating the distance between the second equipment device and the origin according to the coordinates of the second equipment device, namely calculating the distance between the points A, B, C, D and E in the first quadrant and the origin O respectively, sequencing all the points in the area according to the distance between each second equipment device and the origin from far to near, and marking the points with the same distance specially and further judging.

For example, when the second equipment devices in the area are sorted, if there are at least two second equipment devices in the area with equal distances from the origin, the second equipment device closest to the preset bisector of the angle of the area is sorted in the front. Referring to fig. 3, if there are a plurality of points farthest from the origin in the coordinate region, the points in front of the coordinate region are determined according to a preset angle bisector of the coordinate region, for example, a 45-degree angle bisector L using the origin as an end point, and this is because the points closer to the 45-degree angle bisector L are more convenient to route than the points farther from the 45-degree angle bisector L, which is beneficial to shortening the routing length.

For example, after the above processing, if there still exist at least two farthest points with the same distance from the origin, the area is bisected by a preset angle bisector, and one second equipment device with the largest number of second equipment devices in the area where the at least two second equipment devices are located is ranked in the top. Referring to fig. 3, assuming that the point a and the point B are the farthest points having the same distance from the origin, the area is divided by a 45-degree bisector L, the number of the second equipped devices in the area where the point a and the point B are located is determined, and the second equipped devices corresponding to the points in the area where the total number of the second equipped devices is larger are sorted in the top.

And S230, sequentially determining the second equipment devices or the first equipment devices connected with each second equipment device according to the sequence of the second equipment devices and the preset wiring rule corresponding to the region.

Specifically, through a series of processing in step S220, the sequence of the second equipment devices in each area may be determined, a set of the second equipment devices of each area may be generated according to the sequence, and the second equipment devices connected to each second equipment device may be sequentially determined according to the sequence of the second equipment devices in the set, for example, each second equipment device may be connected to the second equipment device closest to the second equipment device according to a wiring manner specified by a preset wiring rule, and the last second equipment device in the sequence may be connected to the origin, so that the second equipment devices in each area may be sequentially connected from far to near, and may be finally connected to the first equipment device.

S240, when the wiring manner between the second equipment devices of the adjacent regions can be optimized, optimizing the wiring manner between the second equipment devices of the adjacent regions so as to minimize the wiring distance.

According to the technical scheme of the embodiment, the second equipment devices in the area are sequenced from far to near according to the distance between the second equipment device in each area of the coordinate system and the original point, and the second equipment device or the first equipment device connected with each second equipment device is sequentially determined according to the sequencing of the second equipment devices and the preset wiring rule corresponding to the area, so that the second equipment devices in the area can be sequentially connected from far to near according to the preset wiring rule, the reduction of the wiring length in each area is facilitated, the cable loss is reduced, and the cable and construction cost is saved.

On the basis of the above embodiments, the present embodiment further optimizes the photovoltaic power plant wiring method shown in fig. 3. Illustratively, the region in the coordinate system includes a first preset region; correspondingly, step S230 specifically includes:

s310, whether the second equipment device ranked in the ith order in the first preset area and the second equipment device closest to the second equipment device can carry out Manhattan distance type wiring or not is judged.

If the ith second equipment device and the nearest second equipment device in the first preset area can perform the Manhattan distance type wiring, executing S320; if the second equipment device ranked in the ith order in the first preset region and the second equipment device closest to the second equipment device cannot perform the manhattan distance type wiring, S340 is executed.

The photovoltaic modules in the first preset area are arranged to form a regular square matrix, and therefore the preset wiring rule corresponding to the first preset area can be Manhattan distance type wiring. The manhattan distance is also called a city block distance, namely the sum of the distance of two points in a coordinate axis along the X-axis direction and the distance along the Y-axis direction, and correspondingly, the manhattan distance type wiring is performed according to a manhattan distance measuring path between the two points.

The coordinate system area shown in fig. 3 may be a first preset area, and the technical solution of the present embodiment is exemplarily described with reference to fig. 3. The positions of the second equipment devices in the first quadrant are points A, B, C, D and E, and the second equipment devices are sorted from far to near according to the distance between the second equipment devices in the area and the origin, so as to obtain a sorting set [ A, B, C, D, E ] of the second equipment devices. For the first preset area, whether the second equipment device ranked in the ith order and the second equipment device closest to the second equipment device ranked in the ith order can perform the Manhattan distance type wiring or not is sequentially judged, for example, a point A is the second equipment device ranked in the 1 st order, a point B is closest to the point A, and whether the point A and the point B can perform the Manhattan distance type wiring or not is judged. If a triangle in the origin direction is drawn with the line segment AB as a diagonal line and exists, the point a and the point B can be manhattan-distance-type wired.

And S320, connecting the two according to the Manhattan distance type wiring.

And connecting the point A with the point B by using a line segment Aa and a line segment aB, wherein the line segments Aa and Ba are the wiring lines of a second equipment device (a junction box) at the point A and the point B, the vertex a is the intersection point of the wiring path between the point A and the point B, and the point a continuously participates in subsequent wiring planning.

S330, determining the intersection point of the wiring path between the second equipment device ranked in the ith order and the second equipment device closest to the second equipment device, judging whether the intersection point and the second equipment device closest to the intersection point in the area can carry out Manhattan distance type wiring, and carrying out wiring according to the judgment result.

The first preset area comprises n second equipment devices, i is more than or equal to 1 and less than or equal to n, and the second equipment device for sorting the nth is connected with the origin.

Illustratively, referring to fig. 3, the second equipped device closest to the intersection a in the sorted set of second equipped devices [ a, B, C, D, E ] is the second equipped device at the point C, and thus it can be continuously determined whether the intersection a and the point C can be manhattan-distance-wired. And drawing a triangle in the original point direction by taking the line segment aC as a diagonal line, wherein the triangle exists, the point a is connected with the point C by the line segment ab and the line segment bC, the line segment ab and the line segment bC are wiring lines of a second equipment device (a combiner box) at the point a and the point C, and the intersection point b continuously participates in subsequent wiring planning. And by analogy, the wiring of all the second equipment devices in the sequencing set is sequentially completed according to the method, so that the second equipment devices in the region are sequentially connected from far to near.

The second equipment device at the point E is connected with the second equipment device at the point D in a Manhattan distance type wiring mode, the intersection point D is closer to the origin O, and therefore the intersection point D can be connected with the origin O through straight line wiring, and the connection between the second equipment device at the point E and the first equipment device at the origin O is achieved. To this end, the combiner boxes at the points A, B, C, D and E are combined to the box transformer at the origin O, so that the electric energy conversion is performed.

And S340, connecting the two through a straight line.

For example, assuming that the point a is the second equipment device in the order 1, and the point B is closest to the point a, if a triangle cannot be drawn according to the point a and the point B (this case is not shown in fig. 3), the two cannot be manhattan-distance-type wired therebetween, and the two are connected by a straight-line wire.

S350, judging whether the second equipment device which is closer to the origin in the second equipment device ranked in the ith order and the second equipment device which is closest to the ith order and other second equipment devices which are closest to the second equipment device in the area can carry out the Manhattan distance type wiring or not, and carrying out the wiring according to the judgment result.

For example, if the point a is closer to the origin O in the point a and the point B, the point a continues to participate in the subsequent wiring planning, and it may be determined whether other second equipment devices closest to the point a, for example, the second equipment device at the point C, in the sorted set [ a, B, C, D, E ] of the second equipment devices can perform the manhattan distance type wiring with the second equipment device at the point a, and perform the wiring according to the corresponding determination result.

According to the technical scheme, according to the sequencing of the second equipment devices in the first preset area, the second equipment devices in the area are subjected to Manhattan distance type wiring, each second equipment device in the area is connected with the nearest point in the area, and the second equipment device which is sequenced last is connected with the first equipment device, so that the second equipment devices in the first preset area are sequentially connected with the first equipment devices.

On the basis of the above embodiments, the present embodiment further optimizes the photovoltaic power plant wiring method shown in fig. 3. Exemplarily, the region in the coordinate system may further include a second preset region; accordingly, step S230 may further include:

and S410, setting a ray area in a preset angle range by taking the position of the second equipment device in the second preset area in the sequence of the kth as a vertex.

The second preset area can be a user-defined area in the photovoltaic power station, for example, the second preset area is an area in which the photovoltaic modules are irregularly arranged. The preset wiring rule corresponding to the second preset area may be euclidean distance type wiring. The euclidean distance generally refers to the euclidean distance, i.e., the linear distance between two points in space, and accordingly, the euclidean distance wiring connects the two points by a linear routing.

Fig. 4 is a schematic diagram of a distribution position of the equipped devices in another coordinate system area provided by the embodiment of the present invention, and fig. 4 schematically illustrates another distribution and routing connection of the equipped devices in the coordinate system area shown in fig. 2, where the coordinate system area may be a second predetermined area. The present embodiment is also schematically illustrated by taking a photovoltaic power station as a centralized photovoltaic power station, the first equipment device is a box transformer substation, and the second equipment device is a combiner box, as shown in fig. 4, the first equipment device, i.e., the box transformer substation, is located at the origin of coordinates O, and the second equipment device, i.e., the combiner box is distributed in the area of the coordinate system, as shown by points A, B, C, D and E in the first quadrant.

Illustratively, referring to fig. 4, the second equipment devices are sorted from far to near, resulting in a sorted set of second equipment devices [ a, B, C, D, E ]. And for the second preset area, setting a ray area of a preset angle range by taking the position of the second equipment device in the second preset area in the sequence No. 1, namely the point A as a vertex. The preset angle range can be set according to needs, for example, the preset angle range is 90 degrees, a line segment AO where the point a and the origin O are located is taken as an angular bisector, two rays which form an angle of ± 45 degrees with the AO are made, and a ray area is formed.

S420, judging whether a second equipment device closest to the ray region of the kth second equipment device exists in the ray region of the kth second equipment device.

If the second equipment device closest to the k-th equipment device exists in the ray area of the second equipment device ranked in the k-th order, executing S430; if there is no second equipment device closest to the kth second equipment device in the ray region of the kth second equipment device, S450 is performed.

And S430, connecting the two by using a straight line routing.

Illustratively, when k is equal to 1, a second equipped device closest to the point a exists in a ray region of the second equipped device ranked at 1, the second equipped device is a second equipped device at the point C in the ranked set, the point a and the point C may be connected by straight-line routing, the routing between the corresponding two second equipped devices is realized, and the point a is removed from the ranked set.

S440, judging whether a second equipment device with the closest distance exists in the ray area of the second equipment device ranked at the k +1, and carrying out wiring according to the judgment result.

Wherein the second preset area comprises m second equipment devices, and k is more than or equal to 1 and less than or equal to m.

Illustratively, the point B that is farthest from the origin O as the rest, i.e., the position of the second equipped apparatus in the order 2, is selected from the sorted set of the second equipped apparatuses. And taking a line segment BO where the point B and the origin O are positioned as an angular bisector, and making two rays which form an angle of +/-45 degrees with the BO to form a ray region. In the ray area of the second equipment device at the point B, there is a second equipment device closest to the point B, the second equipment device is the second equipment device at the point C in the sorting set, the point B and the point C can be connected through linear routing, wiring between the two corresponding second equipment devices is realized, and the point B is removed from the sorting set. And by analogy, according to the sequencing of the second configuration devices, completing the wiring of all the second configuration devices in the sequencing set in sequence, so that the second configuration devices in the region are connected in sequence from far to near.

S450, determining a second equipment device closest to the ray area of the kth second equipment device, calculating a first distance between the kth second equipment device and the origin, and calculating a first length of the routing between the origin and the second equipment device closest to the ray area of the kth second equipment device.

For example, if there is no second equipment device closest to the second equipment device within the ray region of the second equipment device, the point is added to the first set and the point is deleted from the sorted set of the second equipment device. For the point in the first set, taking point E as an example, if there is no second equipment device closest to the point E in the ray region of the point E, determining a point D of the second preset region closest to the ray region of the point E. A first distance between the point E and the origin O, i.e., the length of the line segment OE, i.e., a first distance L1, is OE. The first length OF the trace between the point D closest to the ray area OF the point E and the origin O is the length OF the line segment OD, i.e., the first length L2 is equal to OD (if the point D is connected to the origin O via a point F (not shown), the first length should be the sum OF the line segment DF and the line segment OF). .

S460, judging whether the ratio of the first distance to the first length is larger than or equal to a preset threshold value.

And S470, connecting the second equipment device with the k-th order with the origin.

Illustratively, assume that the preset threshold is α, wherein the magnitude of α can be set according to the requirement. If L1/L2 < α, it indicates that the distance between points D and E is too far, and it is not necessary to connect point E and origin O through point D, and it is only necessary to connect point E and origin O directly by straight-line routing.

S480, connecting the second equipment device which is ranked the kth with the second equipment device which is closest to the ray area.

If L1/L2 is larger than or equal to alpha, the distance between points D and E is relatively short, the points E and the points D can be directly connected through linear wiring, the points E are connected to the original point O through the points D, the bridge or buried length is reduced, and the construction cost is reduced.

According to the technical scheme, according to the sequencing of the second equipment devices in the second preset area, the second equipment devices in the area are subjected to Euclidean distance type wiring, each second equipment device in the area is connected with the nearest point in the area, and the ordered connection between the second equipment devices and the first equipment devices in the second preset area is achieved.

In this embodiment, the photovoltaic power station wiring method is further optimized, and accordingly, the method of this embodiment specifically includes:

Fig. 5 is a schematic diagram of a distribution position of another equipment device of a photovoltaic power plant provided by an embodiment of the present invention, fig. 6 is a schematic diagram of a distribution position of another equipment device of a photovoltaic power plant provided by an embodiment of the present invention, fig. 5 and fig. 6 both schematically illustrate a situation in which each second equipment device in the photovoltaic power plant is connected by manhattan distance type wiring, fig. 5 illustrates a wiring scheme before optimization, and fig. 6 illustrates a wiring scheme after optimization. This embodiment will be schematically described with reference to fig. 5 and 6 as an example. The four quadrants of the rectangular coordinate system shown in fig. 5 and 6 correspond to four regions in the coordinate system, and first determine whether an optimizable space exists between the first quadrant and the adjacent quadrant, and find out the nearest points in the first quadrant to the second quadrant and the fourth quadrant, which are the point D and the point E, respectively. The second equipment devices at points D and E are the second equipment devices to be optimized.

And S540, calculating a second distance between the second equipment device to be optimized and the second equipment device connected with the second equipment device to be optimized and a third distance between the second equipment device to be optimized and the nearest second equipment device in the adjacent area of the second equipment device to be optimized.

Referring to fig. 5, for example, for the second arming device to be optimized at point D, point D is connected to point D, the second distance between point D and point D is D1, point F in the second quadrant is closest to point D, and the distance between point D and the line segment Ff, i.e., the vertical distance between point D and point F, is a third distance D2. For the second equipment device to be optimized at point E, point E is connected to point d, the second distance between point E and point d is E1, point j in the second quadrant is closest to point E, and the distance between point E and line segment Jj, that is, the vertical distance between point E and point j is a third distance E2.

And S550, judging whether the second distance is greater than the third distance.

If the second distance is greater than the third distance, executing S560; if the second distance is less than or equal to the third distance, S570 is performed.

And S560, connecting the second equipment device to be optimized and the nearest second equipment device in the adjacent area of the second equipment device to the origin.

For the second equipment device to be optimized at the point D, because D1 is less than D2, the wiring mode between the first quadrant and the second quadrant has no optimization space, and the wiring mode in the first quadrant and the second quadrant does not need to be optimized. For the second outfit to be optimized at point E, there is an optimization space between the first and fourth quadrants because E1 > E2. The same can confirm that the optimization space exists between the second quadrant and the third quadrant.

With reference to fig. 5 and 6, for the second equipment device to be optimized between the optimizable quadrants, for example, at the point E, a point j closest to the point E in the fourth quadrant is searched, and the point E and the point j are respectively connected to the coordinate axes between the two quadrants and connected to the origin O through the coordinate axes. In the original wiring method, it is also necessary to newly perform wiring at a point between the point E and the point J and the origin O, for example, by directly connecting the point D to the origin O and connecting the point J and the point K to the coordinate axis. For the second and third quadrants, G, H are connected by a vertical segment on the x-axis.

And S570, finishing the wiring.

According to the technical scheme of the embodiment, when the wiring mode between the second equipment devices of the adjacent regions can be optimized, the wiring mode between the second equipment devices of the adjacent regions is optimized to obtain an overall better wiring mode, so that the wiring length is shortened, the cable loss is reduced, and the cable and construction cost are saved.

In this embodiment, for example, according to the distribution position of the second equipment devices in the photovoltaic power station, the coordinate system is rotated by a preset rotation angle, so that the second equipment devices are uniformly distributed in the coordinate system; the coordinate system is divided into a plurality of regions according to a preset rotation angle of the coordinate system.

Specifically, when the distribution of the photovoltaic modules in the photovoltaic power station is irregular, for example, the photovoltaic modules form an oblique square matrix, in order to optimize the wiring manner between the first equipment device and the second equipment device, the coordinate system may be rotated by a preset rotation angle with the origin as the center, the size of the preset rotation angle may be input by the user according to the requirement, and when the user does not input the rotation angle, the default preset rotation angle is 0 °. After the coordinate system is rotated by the preset rotation angle, the coordinate system can be divided into four areas according to the positions of the rotated first quadrant to the rotated fourth quadrant, the coordinates of second equipment devices in the four areas are obtained, the areas are wired according to the preset wiring rule corresponding to each area according to the coordinates of the second equipment devices in the areas, the second equipment devices in the areas are connected to the first equipment devices, and the wiring mode between the second equipment devices in the adjacent areas is optimized, so that the wiring distance is shortest.

Exemplarily, when a plurality of preset rotation angles exist in the coordinate system, wiring is performed on each region according to each preset rotation angle, and the wiring mode of adjacent regions is optimized; and calculating the total cost of the wiring mode corresponding to each preset rotation angle, and determining the wiring mode with the lowest total cost as the optimal wiring mode of the photovoltaic power station.

Specifically, when a user inputs a plurality of preset rotation angles, the wiring of each region and the wiring optimization between adjacent regions can be performed according to each preset rotation angle, and the total cost can be calculated according to parameters such as the cost of a cable, a bridge or the cost of burying, and the like required by the wiring input by the user. And comparing the total cost corresponding to each preset rotation angle, and displaying the wiring mode with the lowest total cost to a user as an optimal wiring mode.
