Technical Field

[0003] The present application relates to the field of power electronics technology, and in particular to a method, device, and medium for generating an electrical topology diagram of a power system. Background Art

[0004] With the development of power electronics technology, the application of power equipment in power systems is becoming more and more common. When connected to a DC power supply, power equipment can achieve functions such as power optimization, monitoring, and rapid shutdown. Power equipment mainly includes micro inverters, circuit breakers, power optimizers, monitors, etc. The DC power supply can be a photovoltaic DC power supply, or a fuel cell and energy storage battery.

[0005] Typically, one or more DC power sources are configured with a power device. Multiple power devices are connected in parallel or series to form a power device group and connected to a convergence device, which can be an AC combiner box, a DC combiner box, or a string inverter. For example, a typical 100kW distributed photovoltaic system will have 8 to 16 power device groups, 50 to 300 power devices, and 200 to 300 photovoltaic modules. When a power device or DC power source experiences an anomaly, to quickly locate the fault and improve troubleshooting efficiency, it is necessary to obtain a diagram of the electrical topology of the power system. This information includes the power device group to which each power device belongs, its order within the power device group, and the convergence device number and port number to which the power device group is connected. However, there is currently no simple and easy-to-use method for obtaining a diagram of the electrical topology of a power system.

[0057] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0058] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0059] Although the present application makes various references to certain modules in the system according to embodiments of the present application, any number of different modules can be used and run on a computing device and / or processor. The modules are illustrative only, and different aspects of the system and method can use different modules.

[0060] It should be understood that when a unit or module is described as being "connected" or "coupled" to other units, modules, or blocks, it can refer to being directly connected or coupled, or communicating with other units, modules, or blocks, or there can be intervening units, modules, or blocks, unless the context clearly indicates otherwise. As used herein, the term "and / or" may include any and all combinations of one or more of the associated listed items.

[0061] Figures 1 and 2 are structural schematic diagrams of the power system provided in this application. The power system includes multiple DC power supplies, multiple power device groups 10 and a convergence device 20. Each power device group 10 is connected to the corresponding convergence device 20, and each power device group 10 includes multiple power devices 101 respectively connected to at least one DC power supply.

[0062] The DC power supply can be a photovoltaic DC power supply as shown in Figures 1 and 2, or a fuel cell and an energy storage battery. Specifically, the photovoltaic DC power supply can be a single photovoltaic module, or multiple photovoltaic modules connected in series and / or parallel, or multiple photovoltaic cell substrings connected in series and / or parallel.

[0063] The power device 101 may be a micro inverter, a circuit breaker, an optimizer, a monitor, etc. Multiple power devices 101 in the same power device group 10 may be connected in parallel as shown in FIG1 , or may be connected in series as shown in FIG2 .

[0064] Each power device has corresponding electrical topology location information. The electrical topology location information includes at least the group number of the power device group to which the power device belongs, and the ranking of the power device within the power device group to which it belongs. Each power device group has a group number, which can be represented by the input port number of the bus device to which the power device group is connected, such as 1, 2, 3, 4, etc. Each power device has a relative position ranking within the power device group to which it belongs. For example, as shown in Figure 1, the ranking of the power devices in the power device group from the closest to the bus device input port to the farthest from the bus device input port is numbered 1, 2, 3, ..., m; or, as shown in Figure 2, the ranking of the power device group from the positive pole to the negative pole is numbered 1, 2, 3, ..., n. The electrical topology location information also includes the bus device number. The electrical topology location information of the power device is usually expressed as XYZ, where X represents the bus device number, Y represents the input port number of the bus device, and Z represents the ranking of the power device within the power device group to which it belongs.

[0065] Each power device has corresponding device information. This device information can be unique identification information such as the device serial number of the power device. The carrier of the device information, i.e., the device identifier, can be a QR code provided on the power device, which is used to indicate the device information of the power device. It is understood that the device identifier is not limited to a QR code and can also be other forms of information carriers or identification symbols such as a one-dimensional code.

[0066] The converging device 20 can be an inverter for converting the DC power provided by the power device group into AC power for output; the converging device 20 can also be a DC combiner box or an AC combiner box for converging the DC power or AC power output by each power device group. Figures 1 and 2 illustrate an example of a converging device connected to two power device groups. It is understood that the power system can include two or more converging devices 20. The converging device 20 can have one or more input ports, and each power device group 10 is connected to an input port of a converging device 20.

[0067] The power system also includes at least one management module, each corresponding to a convergence device 20. The management module communicates with each power device group connected to the convergence device, for example, by coupling with each power device group connected to the convergence device via current transformers, and communicating with each power device via, for example, a power line carrier, but not limited to such. The management module can also be integrated into the corresponding convergence device 20. The management module and the convergence device can each have a unique identifier, or their unique identifiers can be unified into one. Generally, the convergence device is represented by a management module identifier or a unified identifier. The management module can be implemented using a controller, etc.

[0068] The power system also includes a gateway device and a monitoring platform. The gateway device is compatible with multiple data transmission methods, enabling communication with the management module and various power devices, as well as data transmission with the monitoring platform and / or app. The monitoring platform can exchange data with the gateway device and / or app, enabling online monitoring, fault diagnosis, intelligent alarms, and operation and maintenance management of the power system. It can automatically monitor the operating status of each installed power device and automatically generate alarms in the event of an abnormality.

[0069] The present application provides a method for generating an electrical topology diagram of an electric power system. As shown in FIG1 and FIG2 , the electric power system includes multiple DC power supplies, multiple power device groups 10, and at least one busbar device 20. Each of the power device groups 10 is connected to a corresponding busbar device 20. Each of the power device groups 10 includes multiple power devices 101 respectively connected to at least one of the DC power supplies. As shown in FIG3 , the method includes:

[0070] S302: Identify at least one information identification diagram corresponding to each of the convergence devices to obtain electrical topology location information and device information of power devices connected to each of the convergence devices.

[0071] The information identification diagram includes at least one cell, and the at least one cell has a device identification of the power device and electrical topology position information for representing the corresponding power device.

[0072] The electrical topology location information of the power device includes at least the group number of the power device group to which the power device belongs and the order of the power device in the power device group. Furthermore, the electrical topology location information may also include the number of the busbar device.

[0073] The device information is, for example, the device serial number of the power device.

[0074] S304: Generate an electrical topology relationship diagram of the power system based on the electrical topology location information and device information of the power devices connected to each of the converging devices.

[0075] It can be understood that in this application, the electrical topology relationship diagram of the power system is used to display the electrical topology location information and equipment information of each power device and the correlation between the two. The electrical topology relationship diagram can be in the form of an information list, or a topology diagram, or other chart form that is easy to display.

[0076] Based on the above steps S302-S304, the power system is divided into units of convergence devices, and the electrical topology location information and device information of the power devices connected to each convergence device are obtained through the identification information identification diagram, which provides a more easily implementable method for generating the electrical topology relationship diagram of the power system, facilitates the intelligent operation and maintenance of the power system, and improves the efficiency of operation and maintenance work.

[0077] The information identification diagram template shown in FIG4 includes a table area. Each cell in the table is used to paste the device identification of the power device. There is a one-to-one mapping relationship between the row and column position information of the cell and the electrical topology position information of the power device.

[0078] According to the mapping relationship, the device identifications of all power devices under a converging device are sequentially pasted into the cells of the information identification diagram template to obtain the information identification diagram.

[0079] Optionally, the information identification diagram template also includes a number cell and an identification cell for the confluence device, which are used to fill in its number and paste its unique identification, respectively.

[0080] In one embodiment, as shown in FIG5 , identifying at least one information identification diagram corresponding to each of the converging devices to obtain electrical topology location information and device information of the power devices connected to each of the converging devices includes:

[0081] S502: Identify the device identification of each power device in each information identification map to obtain device information of the power device;

[0082] S504: Identify the row and column position information of the cell where each device identifier is located, and obtain the electrical topology position information of each power device based on a mapping rule.

[0083] The mapping rule is used to determine a one-to-one mapping relationship between the row and column position information of the cells in the information identification diagram and the electrical topology position information of the power device.

[0084] The mapping rules may be automatically obtained based on the actual electrical topology design scheme corresponding to the convergence device and the table design of the information identification diagram template, or may be manually input.

[0085] For example, the target image can be obtained by taking a photo of the information identification diagram using the camera function of the electronic device; or the target image can be obtained by scanning the information identification diagram using the scanning function of the electronic device. The electronic device then recognizes the target image, including identifying the device identification of the power device in each cell to obtain device information, identifying the row and column position information of the cell where each device identification is located, and obtaining the electrical topology position information of each power device based on the mapping rules, thereby obtaining the device information and electrical topology position information of the power device corresponding to each cell.

[0086] In a first exemplary embodiment, an information identification diagram, as shown in FIG6 , is provided for recording the device identifications of the various power devices connected to the convergence device 1 shown in FIG7 . The entire table in the information identification diagram can represent all the power devices in a convergence device, with each cell in the table representing a power device. Each cell in the information identification diagram has a corresponding device identification. It is understood that a blank cell indicates that no power device is connected at that location.

[0087] The identification information of the convergence device corresponding to the information identification diagram includes the convergence device number and / or convergence device identification. The convergence device number is filled in the convergence device number cell in the information identification diagram, and the device identification of the convergence device is pasted in the convergence device identification cell in the information identification diagram.

[0088] The information identification diagram is identified by electronic equipment to obtain the device information of the power device corresponding to each cell. Then, the electrical topology location information of the power device and the device information can be associated and stored in an information list as shown in Table 1.

[0089] The electronic device identifies each cell in the information identification map based on a mapping rule. The mapping rule is used to determine a one-to-one mapping relationship between the row and column positions of the cells in the information identification map and the electrical topological positions of the power devices. In this example embodiment, the mapping rule is as follows: each row of cells represents a power device group, the column number of the cell represents the order of the power device within the power device group, and the group number of the power device group is the row number.

[0090] It is understandable that, in other embodiments, each column of the information identification diagram may represent a power device group, and the row number of the cell indicates the ranking number in the power device group.

[0091] When the number of power devices in at least one power device group is too large, that is, the number of cells in a row of the information identification diagram is less than the number of power devices in a certain power device group, the device identifications of all power devices in the power device group can be pasted in cells in multiple rows.

[0092] In a second exemplary embodiment, an information identification diagram is provided as shown in FIG8 for recording the device identifications of the various power devices connected to the converging device 1 as shown in FIG9. As shown in FIG8, the first and second rows of the information identification diagram are used to affix the device identifications of the power devices in the first power device group, and the third and fourth rows are used to affix the device identifications of the power devices in the second power device group.

[0093] Therefore, an electronic device is used to identify each cell in the information identification diagram shown in FIG8 based on a mapping rule to obtain the device information of the power device in each cell. The electrical topology location information of the power device and the device information can then be associated and stored in an information list as shown in Table 2. In this example embodiment, the mapping rule is as follows: two rows of cells represent a power device group, and the power device group numbers are sorted in order according to their relative positions in the table.

[0094] Table 1

[0095] Table 2

[0096] In other examples, the table design of the information identification diagram template can also be changed. For example, if some rows of the table do not have the group number of the power device group, then the row is a continuation of the previous row with the group number of the power device group. For example, the second row in the information identification diagram does not have the group number of the power device group, so the second row is a continuation of the previous row with the group number of the power device group, that is, a continuation of the first row. Alternatively, as shown in Figure 10, special marks are designed at the group number position of some rows of the table to indicate that the row is a continuation of the previous row with the group number of the power device group. For example, the group number position of the second row in the information identification diagram has a special mark, so the second row is a continuation of the previous row with the group number of the power device group, that is, a continuation of the first row. Therefore, the electrical topology position information corresponding to cell (2,1) is 1-7, which is used to indicate the position of the seventh power device in the first power device group.

[0097] Of course, there is also a situation where the number of power devices in a power device group is very small, that is, when the number of cells in a row of the information identification diagram is much larger than the number of power devices in a certain power device group, the device identifications of the power devices in multiple power device groups can be pasted in cells in one row.

[0098] In a third exemplary embodiment, an information identification diagram is provided as shown in FIG11 for recording the device identifications of the various power devices connected to the convergence device 1 shown in FIG12. As shown in FIG11, the first row of the information identification diagram is used to affix the device identifications of the power devices in the first and second power device groups, and the second row is used to affix the device identifications of the power devices in the third and fourth power device groups.

[0099] Therefore, an electronic device is used to identify each cell in the information identification diagram shown in FIG11 based on a mapping rule to obtain the device information of the power device in each cell. The electrical topology location information of the power device and the device information can then be associated and stored in the information list shown in Table 3. In this exemplary embodiment, the mapping rule is: one row represents two power device groups, and the group numbers of the power device groups are sorted in order according to their relative positions in the table, top to bottom, and left to right.

[0100] Table 3

[0101] When a convergence device is connected to a large number of power devices, multiple information identification diagrams can be used to record the device identification of each power device connected to the convergence device. The identification information of the convergence device, such as the convergence device number and convergence device identification, can be marked in designated locations on the multiple information identification diagrams; alternatively, the convergence device number can be recorded in the convergence device number cell of each information identification diagram, and the convergence device identification is only pasted in the convergence device identification cell of the first information identification diagram. The information identification diagram also has a page number identification area to indicate the splicing order of the multiple information identification diagrams.

[0102] In the fourth exemplary embodiment, the two information identification diagrams shown in Figures 13A and 13B are both pasted with device identifications of power devices connected to the convergence device 1 shown in Figure 14. It is understandable that the device identifications of all power devices in the same power device group should be pasted in the same table as much as possible.

[0103] Therefore, an electronic device is used to identify each cell in the information identification diagram shown in Figures 13A and 13B based on mapping rules to obtain the device information of the power device in each cell. The obtained information can then be integrated to associate the electrical topology location information and device information of all power devices connected to the first convergence device and store them in an information list as shown in Table 4.

[0104] Table 4

[0105] In step S304, specifically, based on the information list corresponding to each converging device, the electrical topology location information of the power devices connected to each converging device and the corresponding device information are summarized and integrated to generate an electrical topology relationship diagram of the power system.

[0106] Furthermore, as shown in FIG15 , in the case where there are multiple converging devices, generating the electrical topology relationship diagram of the power system based on the electrical topology location information and device information of the power devices connected to each of the converging devices includes:

[0107] S1502: Based on the electrical topology location information and device information of the power devices connected to each of the busbar devices, generate corresponding electrical topology relationship sub-graphs;

[0108] S1504: Combine the electrical topology relationship sub-graphs to obtain the electrical topology relationship graph of the power system.

[0109] The electrical topology relationship diagram can have various forms. In some embodiments, the electrical topology relationship diagram of the power system is generated based on the electrical topology location information and device information of the power devices connected to each of the convergence devices, including: associating the device information and electrical topology location information of each of the power devices and storing them in an information list to obtain the electrical topology relationship diagram.

[0110] The electrical topology relationship chart can directly store the electrical topology location information and device information of each power device in the power system in the same row in the form of an information list as shown in Table 5. The electrical topology location information of the power device also includes the number of the connected bus device. For example, as shown in Figure 16, the power system includes bus devices 1 and 2. Bus devices 1 and 2 are respectively connected to two power device groups, each of which includes six power devices.

[0111] In some other embodiments, generating the electrical topology relationship diagram of the power system based on the electrical topology location information and device information of the power devices connected to each of the convergence devices includes: generating the electrical topology block diagram of the power system based on the electrical topology location information of each of the power devices; binding the device information of each of the power devices with the corresponding power device in the electrical topology block diagram to obtain the electrical topology relationship diagram.

[0112] Table 5

[0113] Specifically, an electrical topology block diagram of the power system is generated based on the electrical topology location information of each power device corresponding to each busbar. As shown in Figure 17, the electrical topology block diagram includes each busbar and each power device, and their electrical connections. The 1-1-1 in Figure 17 represents the electrical topology location information of the corresponding power device. Then, by binding the device information of each power device to the corresponding power device in the electrical topology block diagram, an electrical topology relationship diagram is generated.

[0114] Among them, the device information of each power device is bound to the corresponding power device in the electrical topology block diagram. Specifically, it can be achieved by any of the following methods: directly displaying any device information on at least one corresponding power device as shown in Figure 18; displaying any device information on an icon, and displaying the icon on at least one corresponding power device; as shown in Figure 19, storing any device information in association with the icon information of an icon, and displaying the icon indicated by the icon information on at least one corresponding power device. The icon information can be any information used to uniquely indicate an icon.

[0115] Furthermore, the electrical topology diagram of the power system may further include at least one real-time parameter of each power device, wherein the real-time parameter of the device is at least one of power generation, output power, output voltage, output current, input power, input voltage, input current, device model, and device operating status.

[0116] In one embodiment, as shown in FIG20 , the method further includes:

[0117] S2002: Acquire at least one real-time parameter of a power device connected to each of the convergence devices;

[0118] S2004: Bind the at least one device real-time parameter with the electrical topology location information and / or device information of the corresponding power device in the electrical topology relationship diagram.

[0119] In the process of generating the electrical topology relationship diagram of the power system, in addition to binding the electrical topology location information and device information of the power equipment, at least one real-time device parameter of the power equipment is also bound to the electrical topology location information and device information of the power equipment. Therefore, in the electrical topology relationship diagram shown in Table 6 or as shown in Figure 21, the abnormal / faulty power equipment can be directly located according to whether the real-time parameters of the equipment are abnormal. For example, the power equipment with electrical topology location information of 1-1-5 and device information of xxxxxx05 is abnormal, thereby realizing intelligent operation and maintenance and improving the work efficiency of operation and maintenance.

[0120] In a further embodiment, in the process of generating the electrical topology relationship diagram of the power system, the identification information of each of the convergence devices can also be obtained, and the electrical topology relationship diagram of the power system can be generated based on the electrical topology location information, device information, and identification information of the convergence devices of the power devices. The electronic device can identify the device identification of each of the convergence devices to obtain the identification information, and then the identification information of the convergence devices corresponding to each power device can be stored in the same row as the electrical topology location information and device information of each power device in the electrical topology relationship diagram in the form of an information list; alternatively, the identification information of each of the convergence devices can be bound to the corresponding convergence device in the electrical topology block diagram. That is, the generated electrical topology relationship diagram of the power system also includes the identification information of each convergence device.

[0121] Furthermore, after generating the electrical topology diagram of the power system, the electrical topology diagram of the corresponding convergence device can be sent to the management module of each convergence device. The electrical topology diagram can be distributed directly to the corresponding management module, or it can be synchronized to the gateway first, and then distributed to the corresponding management module by the gateway.

[0122] Based on the electrical topology diagram, the management module corresponding to each convergence device can obtain the device information of all power devices connected to the convergence device. The management module then sends a signal instruction containing the device information and logical address to each corresponding power device to achieve networking. Therefore, each management module does not need to search for power devices one by one to obtain device information. Instead, it can simply and quickly obtain the device information of all power devices connected to its corresponding convergence device from the electrical topology diagram, improving networking efficiency.
