The photovoltaic modules include multiple photovoltaic cell substrings, and the photovoltaic equipment group is composed of multiple photovoltaic devices, where each photovoltaic device is connected to at least one photovoltaic cell substring. In the operation and maintenance process of a photovoltaic power station, failures are inevitable.

[0072] Figures 1 to 5 In the example, each photovoltaic device has corresponding electrical position information. The electrical position information of the photovoltaic device includes at least the group number of the photovoltaic device group to which the photovoltaic device belongs, and the position sorting information of the photovoltaic device in the photovoltaic device group to which it belongs. Each photovoltaic device group has a group number, such as R1, R2, R3, R4, etc. Furthermore, the group number of the photovoltaic device group can be represented by the number of the busbar device connected to the photovoltaic device group and the number of the busbar device port, such as N1-P1, N1-P2, etc.; the position sorting information of the photovoltaic device in the photovoltaic device group to which it belongs, for example, Figure 1 In the photovoltaic device group, the order from the closest to the converging device port to the farthest from the converging device port is C1, C2, ...

[0073] Each photovoltaic device has corresponding physical location information. The physical location information includes at least the arrangement number of the photovoltaic device. The photovoltaic device can be installed on the back or frame of one of the corresponding photovoltaic modules and electrically connected to all the corresponding photovoltaic modules; the photovoltaic device can also be installed on other locations such as mounting rails and electrically connected to all the corresponding photovoltaic modules. It can be understood that all photovoltaic devices in the photovoltaic power generation system form a photovoltaic device array, and the photovoltaic device array includes multiple photovoltaic device rows. Each photovoltaic device in each photovoltaic device row has a corresponding position sequence, and the arrangement number of the photovoltaic device indicates the physical location information of the photovoltaic device. For example, 1-1 indicates that the photovoltaic device is located at the first position in the first photovoltaic device row.

[0074] Each photovoltaic device has corresponding device information. The device information of the photovoltaic device may be unique identification information such as the product serial number of the photovoltaic device. The carrier of the device information, i.e., the device identification, may be a QR code set on the photovoltaic device, and the device information of the photovoltaic device may be obtained by identifying the QR code. It is understood that the device identification is not limited to a QR code, but may also be other forms of information carriers or label codes such as a one-dimensional code.

[0075] Each photovoltaic component has corresponding physical location information. In a photovoltaic power generation system, multiple photovoltaic components form a photovoltaic component array, and the physical location information of the photovoltaic component may include the row and column numbers of the photovoltaic component to indicate the row and column positions of the photovoltaic component in the photovoltaic component array, for example, 1-1 indicates that the photovoltaic component is located in the first row and the first column. In the case of a photovoltaic power generation system with multiple photovoltaic component arrays, the physical location information of the photovoltaic component may also include the orientation information of the photovoltaic component array to which it belongs, for example, ES-1-1 indicates that the photovoltaic component is located in the first row and the first column of the photovoltaic component array in the southeast, and NS-1-1 indicates that the photovoltaic component is located in the first row and the first column of the photovoltaic component array in the southwest. In other embodiments, the physical location information of the photovoltaic component may also include information such as the azimuth, inclination, and orientation of the photovoltaic component.

[0076] The present application provides a method for generating a layout diagram of a photovoltaic power generation system, such as Figure 6 As shown, the following steps are included:

[0077] S601: Acquire device information and first physical location information of each photovoltaic device;

[0078] The first physical location information of the photovoltaic device includes the physical location information of the photovoltaic device.

[0079] The device information and the first physical location information of each photovoltaic device may be obtained by sequentially scanning the device identification of each photovoltaic device based on the physical location of each photovoltaic device.

[0080] The device information and the first physical location information of each photovoltaic device can also be obtained based on an information identification map for identifying the photovoltaic power generation system. The information identification map includes at least one cell, and the cell includes the physical location information and device identification of each photovoltaic device.

[0081] S602: Acquire the physical location information of each photovoltaic component and the second physical location information of the photovoltaic device connected thereto.

[0082] The first physical location information and the second physical location information of the photovoltaic device correspond to each other at least in part. The first physical location information and the second physical location information of the photovoltaic device both include at least the arrangement number of the photovoltaic device in the photovoltaic device array.

[0083] The physical location information of each photovoltaic module and the second physical location information of the connected photovoltaic device can be obtained through the design drawing of the photovoltaic power generation system.

[0084] Exemplarily, the design drawing of the photovoltaic power generation system is a computer-aided design drawing (CAD), and the design drawing contains the correspondence between the physical location information of the photovoltaic module and the second physical location information. Generally speaking, the CAD drawing is retained after the construction of the photovoltaic power station and can be directly obtained. In one embodiment, the physical location of each photovoltaic module can be drawn in the CAD drawing, wherein a rectangular box represents a photovoltaic module, and the row and column position of the rectangular box in the CAD drawing represents the physical location information of the photovoltaic module. For example, the physical location information of the photovoltaic module corresponding to the rectangular box in the first row and the first column is 1-1. In addition, the second physical location information of the corresponding photovoltaic device is displayed on each rectangular box. Exemplarily, the second physical location information of the photovoltaic device is marked according to the arrangement number. In some embodiments, the second physical location information of the photovoltaic device is numbered when the photovoltaic power generation system is designed, and the number will be marked in the design drawing, so it only needs to be identified. For example, the photovoltaic device numbered 1-1 in the photovoltaic module in the first row and the first column indicates that the photovoltaic device connected to the photovoltaic module is located in the first position in the first photovoltaic device row in the photovoltaic device array. Therefore, the physical location information of each photovoltaic component and the second physical location information of the connected photovoltaic device can be obtained based on the design drawing.

[0085] In other embodiments, the design drawing of the photovoltaic power generation system can be generated by professional design software, which can automatically perform layout based on the site construction conditions of the photovoltaic power generation system. The design drawing generated by the professional design software can directly export the physical location information of each photovoltaic component and the second physical location information of the connected photovoltaic device.

[0086] S603: Generate a layout diagram of the photovoltaic power generation system based on the device information, the first physical location information and the second physical location information of the photovoltaic device and the physical location information of the photovoltaic assembly.

[0087] Each virtual unit in the layout diagram contains or hides the physical location information of the corresponding photovoltaic component and the device information of the photovoltaic device connected thereto.

[0088] For example, the physical location information of the photovoltaic module can be represented by characters, or by the location information of the virtual unit in the layout diagram.

[0089] For example, the physical location information of the photovoltaic component corresponding to the virtual unit in the first row and the first column is 1-1, so it is not necessary to use characters on the virtual unit to represent the physical location information of the photovoltaic component.

[0090] It can be understood that based on the correspondence between the first physical location information and the second physical location information, the equipment information of the photovoltaic device corresponding to the physical location information of each photovoltaic component can be determined, and then based on the equipment information of each photovoltaic device and the physical location information of each photovoltaic component, the layout diagram of the photovoltaic power generation system can be obtained.

[0091] Based on steps S601-S603, the device information and the first physical location information of each photovoltaic device are obtained; and the physical location information of each photovoltaic module and the second physical location information of the photovoltaic device to which it is connected are obtained; based on the device information, the first physical location information and the second physical location information of the photovoltaic device and the physical location information of the photovoltaic module, a layout diagram of the photovoltaic power generation system is generated. This embodiment generates a layout diagram of the photovoltaic power generation system based on obtaining the physical location information and device information of the photovoltaic devices in one-to-one correspondence, and obtaining the physical location information of the photovoltaic devices and the physical location information of the corresponding photovoltaic modules, thereby improving the accuracy of the generated layout diagram and improving the installation efficiency and operation and maintenance efficiency of the photovoltaic power generation system.

[0092] In one embodiment, if Figure 7 As shown, generating the layout diagram of the photovoltaic power generation system based on the device information of the photovoltaic device, the first physical location information and the second physical location information and the physical location information of the photovoltaic assembly includes the following steps:

[0093] S701: Based on the correspondence between the first physical location information and the second physical location information of the photovoltaic device, obtaining a mapping relationship between the device information of each photovoltaic device and the physical location information of each photovoltaic module;

[0094] S702: Generate a layout diagram of the photovoltaic power generation system based on the mapping relationship, the device information of the photovoltaic device, and the physical location information of the photovoltaic components.

[0095] The mapping relationship includes the connection relationship between each photovoltaic device and each photovoltaic module. According to the mapping relationship, the device information of the photovoltaic device connected to each photovoltaic module can be determined, and the physical location information of the photovoltaic module is associated with the virtual unit in the layout diagram, so that the layout diagram of the photovoltaic power generation system can be generated.

[0096] In one embodiment, if Figure 8 As shown, generating a layout diagram of the photovoltaic power generation system based on the mapping relationship, the device information of the photovoltaic device and the physical location information of the photovoltaic assembly includes:

[0097] S801: Based on the mapping relationship and the physical location information of the photovoltaic components, determine at least one virtual unit corresponding to each photovoltaic device in a layout template, where one virtual unit corresponds to one photovoltaic component.

[0098] S802: Binding the device information of each photovoltaic device with at least one corresponding virtual unit in the layout diagram template to obtain a layout diagram of the photovoltaic power generation system.

[0099] The layout template may be drawn with a table, the entire table represents a photovoltaic module array, each cell of the table represents a virtual unit, and a virtual unit corresponds to a photovoltaic module of the photovoltaic module array. The layout template may be generated according to the physical location information of each photovoltaic module obtained based on the design drawing.

[0100] Each row of the table of the layout template has a number, such as 1, 2, 3..., and each column also has a number, such as 1, 2, 3..., then the physical location information of any cell in the table can be represented by the row and column numbers. For example, the physical location information of the cell in the first row and first column of the layout template can be represented as 1-1, then the virtual cell with physical location information of 1-1 represents a photovoltaic component located in the first row and first column of the photovoltaic component array.

[0101] According to the mapping relationship, that is, the connection relationship between each photovoltaic device and each photovoltaic module in the photovoltaic power generation system, the photovoltaic device corresponding to each cell in the layout template can be determined, and the device information of each photovoltaic device can be associated. By binding the device information of each photovoltaic device with at least one corresponding virtual unit in the layout template, the layout diagram of the photovoltaic power generation system can be obtained.

[0102] In an example embodiment, Figure 1 , Figure 2 As shown, each photovoltaic device is connected to a photovoltaic module. The acquired device information and first physical location information of each photovoltaic device are stored in a result list, as shown in Table 1, wherein the device information of the photovoltaic device and the corresponding first physical location information are stored in the same row of the result list.
