[0028] Embodiment 1

[0029] Figure 1 It is a flowchart of an electrical topology identification method provided by an embodiment of the present invention. This embodiment is applicable to the situation of identifying the topological association relationship between a substation terminal and a watt-hour meter. This method can be executed by an electrical topology identification device, which can be implemented in the form of hardware and / or software, and the electrical topology identification device can be configured in any electronic device with network communication functions.

[0030] As Figure 1 shown, the electrical topology identification method of the present invention includes:

[0031] S110. Determine a first device list of a target area; the first device list is the association relationship between a first watt-hour meter and a first substation terminal, and the first substation terminal cannot receive the current signal returned by the first watt-hour meter.

[0032] Each terminal in each area of the present invention is associated with multiple electric energy meters. An intelligent switch is configured between each terminal in each area and the electric energy meters. A signal recognition module is configured in the intelligent switch, and the signal recognition module is used to recognize the current signal emitted by the electric energy meter. That is, there is a corresponding relationship between the terminal in each area and the electric energy meter, and there is also a corresponding relationship between the terminal in each area and the intelligent switch. Therefore, there is a corresponding matching relationship among the terminal in each area, the intelligent switch under the terminal in each area, and the electric energy meters under the terminal in each area. Subsequently, by receiving the signal related to the electric energy meter fed back by the intelligent switch, the terminal in each area can accurately locate the associated relationship between the electric energy meter and the terminal in each area, so as to accurately correct the misaligned associated relationship between the electric energy meter and the terminal in each area.

[0033] Among them, the target area can be an area that includes at least a preset number of terminals in each area, which is delimited according to the abnormal line loss of the terminal in each area or the need for topological mapping, and the distance between adjacent terminals in each area is within a preset range. The first terminal in each area is all the terminals in each area within the target area.

[0034] The first device list is the corresponding relationship between the first electric energy meter with an abnormality and the first terminal in each area, that is, the corresponding relationship between the misaligned first electric energy meter and the first terminal in each area. The abnormality may be that the terminal in each area associated with the electric energy meter cannot receive the current signal returned by the electric energy meter. By way of example, as Figure 2 shown, it can be demonstrated that by performing a full-scale topological recognition on the terminals in each area of this area, it is determined that there are abnormal electric energy meters for terminal A, terminal B, and terminal C in each area, that is, electric energy meters that cannot respond to the instructions of the corresponding terminal in each area. Further, it is determined that the number of abnormal electric energy meters associated with terminal A is A1 + Xb + Xc. The number of abnormal electric energy meters associated with terminal B is B1. The number of abnormal electric energy meters associated with terminal C is C1.

[0035] In one embodiment, optionally, determining the device list of the target area includes: obtaining the topological list associated with each terminal in the target area; the topological list is a list of multiple electric energy meters corresponding to each terminal in each area; identifying all the electric energy meters in the topological list. If the characteristic current detection of the electric energy meter fails, the electric energy meter is the first electric energy meter, and a device list is generated.

[0036] Among them, the topological list can be an existing archive table, and the multiple electric energy meters corresponding to each terminal in each area are recorded in the archive table. The topological list can also be a list formed by the relationship between each terminal in each area and the multiple corresponding associated electric energy meters recognized by the existing topological recognition method.

[0037] Further, after performing a full-scale topology identification on all the electricity meters in the topology list, an abnormal electricity meter is detected, marked as the first electricity meter, and a device list is generated. After generating the device list, the first electricity meter with a successful topology in the device list can be excluded in a self-discovery manner to update the device list. A successful topology means that the corresponding relationship between the first electricity meter and the substation terminal that the first electricity meter should originally match is clarified.

[0038] In the embodiment of the present invention, by identifying all the electricity meters in the topology list, if the characteristic current detection of the electricity meter fails, the electricity meter is the first electricity meter, and a device list is generated, which realizes the accurate determination of the first electricity meter with abnormal associations, facilitating the subsequent accurate topology identification of the first electricity meter.

[0039] S120. According to the first device list, send a first detection instruction to the first electricity meter and determine whether there is a current signal returned by the first intelligent switch; the first detection instruction includes information for detecting one first electricity meter, and different first detection instructions are sent at different times; the first detection instruction is sent by all the substation terminals in the target area.

[0040] Specifically, all the first substation terminals in the target area send a first detection instruction to the first electricity meter. Since there is an association relationship between the first intelligent switch, the substation terminal, and the electricity meter, that is, the intelligent switch can only receive the information fed back by its corresponding associated electricity meter, and there is no cross-association between the intelligent switch and the substation terminal, that is, the intelligent switches between each substation terminal do not overlap in association, that is, the intelligent switch can only feed back the information to its corresponding substation terminal. Therefore, it is necessary to determine whether there is a current signal returned by the first intelligent switch in the first substation terminal, so as to accurately locate the association between the first electricity meter and which first substation terminal.

[0041] In this embodiment, optionally, sending a first detection instruction to the first electricity meter according to the first device list includes: according to the arrangement order of the first electricity meters in the device list, all the first substation terminals in the target area send detection instructions to the first electricity meter one by one at preset time intervals, realizing the sequential identification of the first electricity meters, avoiding the situation where all the first electricity meters are identified simultaneously, resulting in messy feedback information, and realizing more accurate identification of the first electricity meters.

[0042] S130. If there is a current signal returned by the first intelligent switch, determine the second substation terminal associated with the first intelligent switch, and associate the second substation terminal with the first electricity meter to complete the electrical topology identification.

[0043] Among them, the second substation terminal may be the same as the first substation terminal or different from it. Generally, it is different because the occurrence of cross-substation situations will lead to inaccurate matching relationships between substation terminals and electricity meters. Therefore, after using this method to identify the first electricity meter, the generally matched substation terminal is usually different from the previously matched first substation terminal. The second substation terminal may be the same as the first substation terminal because there may be abnormalities in the line between the previous electricity meter and the substation terminal, resulting in the electricity meter being unable to feedback information back to the electricity meter. Therefore, during the detection of this method, the line may return to normal, or the intelligent switch can receive and return signals, making the matched second substation terminal possibly the same as the first substation terminal.

[0044] Specifically, if there is a current signal returned by the first intelligent switch, that is, a current signal returned by the first intelligent switch is detected in the first substation terminal, and the first substation terminal is determined as the second substation terminal, and the second substation terminal is associated with the first electricity meter to complete the electrical topology identification. If all the first substation terminals do not receive the current signal returned by the first intelligent switch, it indicates that there may be a problem with the line where the first electricity meter is located, and a prompt message needs to be sent to remind the staff to check in time.

[0045] In this embodiment, optionally, a signal generation module is configured in the intelligent switch. The signal generation module is used to send a current signal according to the identified instruction information. The method further includes: sending a preset instruction information to the first intelligent switch in the target area. The preset instruction information includes an instruction indicating that the intelligent switch feedbacks a current signal; the preset instruction information is sent by all the first substation terminals in the target area, and only one first intelligent switch can be sent an instruction at a time; determining the target substation terminal and establishing an association relationship between the target substation terminal and the first intelligent switch to form a switch list; the target substation terminal is the substation terminal that receives the current signal feedback by the first intelligent switch.

[0046] Specifically, the current signal feedback by the first intelligent switch further includes address information, so that when establishing the switch list, the position information of the first intelligent switch can be clarified, and further the hierarchical relationship of each first intelligent switch can be clarified, realizing the precise refinement of the topology network structure, which is beneficial to more precise fault identification.

[0047] Furthermore, determining the second substation terminal associated with the first intelligent switch includes: determining the second substation terminal associated with the first intelligent switch according to the switch list. Specifically, if there is a current signal returned by the first intelligent switch, query the substation terminal associated with the first intelligent switch according to the switch list and mark it as the second substation terminal, so as to associate the second substation terminal with the first electricity meter to complete the electrical topology identification.

[0048] The technical solution of the embodiment of the present invention first determines the first device list of the target area; the first device list is the association relationship between the first electric energy meter and the first substation terminal, and the first substation terminal cannot receive the current signal returned by the first electric energy meter; that is, first determine the electric energy meter with abnormal association relationship with the terminal substation area, so as to accurately determine which substation terminal the first electric energy meter matches subsequently. Further, according to the first device list, a first detection instruction is sent to the first electric energy meter, and it is determined whether there is a current signal returned by the first intelligent switch; the first detection instruction contains information for detecting one first electric energy meter, and different first detection instructions are sent at different times; to avoid affecting the accuracy of the feedback signal when sending instructions simultaneously. If there is a current signal returned by the first intelligent switch, the second substation terminal associated with the first intelligent switch is determined, and the second substation terminal is associated with the first electric energy meter to complete the electrical topology identification. That is, through the second substation terminal associated with the first intelligent switch of the first intelligent switch, the second substation terminal associated with the first electric energy meter is accurately located, solving the problems of easy cross-station and inability to identify in the existing electrical topology identification, and improving the accuracy of topology identification. In addition, this solution does not require modification of the STA topology module of the original electric energy meter, and can be carried out using the existing electric energy meters with topology functions, which can reduce the investment costs of materials and engineering transformation.

[0049] Embodiment 2

[0050] Figure 3 It is a flowchart of an electrical topology identification method provided by an embodiment of the present invention. The technical solution of this embodiment elaborates in detail on the situation where it is determined that there is no current signal returned by the first intelligent switch in the foregoing embodiment on the basis of the foregoing embodiment. This embodiment can be combined with each optional solution in one or more of the foregoing embodiments. As Figure 3 shown, the electrical topology identification method includes:

[0051] S210. Determine the first device list of the target area; the first device list is the association relationship between the first electric energy meter and the first substation terminal, and the first substation terminal cannot receive the current signal returned by the first electric energy meter.

[0052] It has been elaborated in the foregoing embodiment and will not be repeated here.

[0053] S220. According to the first device list, send a first detection instruction to the first electric energy meter, and determine whether there is a current signal returned by the first intelligent switch; the first detection instruction contains information for detecting one first electric energy meter, and different first detection instructions are sent at different times; the first detection instruction is sent by all substation terminals in the target area.

[0054] It has been elaborated in the foregoing embodiment and will not be repeated here.

[0055] S230. If there is a current signal returned by the first intelligent switch, determine the second substation terminal associated with the first intelligent switch, and associate the second substation terminal with the first watt-hour meter to complete the electrical topology identification.

[0056] As described in the above embodiments, it will not be elaborated here.

[0057] S240. If there is no current signal returned by the first intelligent switch, mark the first watt-hour meter as the second watt-hour meter and generate a second device list.

[0058] Among them, the second device list stores the first watt-hour meters in the first device list for which there is no current signal returned by the first intelligent switch during the identification process of the first watt-hour meters.

[0059] Specifically, if there is no current signal returned by the first intelligent switch, it may be because the current target area is too small and there is no substation terminal corresponding to the first watt-hour meter, or there is a substation terminal corresponding to the first watt-hour meter, but there is a problem with the current line. Therefore, it is necessary to mark the first watt-hour meter as the second watt-hour meter and generate a second device list, so as to re-perform topology identification according to the second device list after all the watt-hour meters in the first device list have been identified, avoiding repeated identification.

[0060] S250. After the identification and detection of the first device list are completed, expand the range of the target area according to a preset plan to obtain an updated target area, and continue the electrical topology identification according to the second device list and the third substation terminal; the updated target area has at least one more third substation terminal than the target area.

[0061] Among them, the preset plan may include the number of times of expanding the target area and the interval of expanding the target area each time.

[0062] Specifically, according to the second device list, send a second detection instruction to the second watt-hour meter and determine whether there is a current signal returned by the first intelligent switch; the second detection instruction contains information for detecting one second watt-hour meter, and different second detection instructions are sent at different times; the second detection instructions are sent by all the third substation terminals in the target area; the third substation terminal is a newly added substation terminal after the expansion of the target area.

[0063] If there is a current signal returned by the first intelligent switch, use the substation terminal associated with the first intelligent switch as the fourth substation terminal, and associate the fourth substation terminal with the second watt-hour meter to complete the electrical topology identification.

[0064] Further, if there is still a second electricity meter that has not fed back a current signal, continue to expand the scope of the target area according to the preset plan until the scope of the target area is expanded to the preset scope and there is still a second electricity meter that has not fed back a current signal, then mark the second electricity meter as a third electricity meter and send a prompt message; the prompt message includes information for detecting the line where the third electricity meter is located.

[0065] In the technical solution of the embodiment of the present invention, when detecting the first electricity meter each time, if it is determined that there is no return current signal from the first intelligent switch, the first electricity meter is marked as a second electricity meter, and a second device list is generated, so that after the identification detection of the first device list is completed, the second device list can be topologically identified again to achieve more accurate topological identification, improve the accuracy and efficiency of topological identification. Further, expand the scope of the target area according to the preset plan to obtain an updated target area, and continue to perform electrical topology identification according to the second device list and the third substation area terminal, avoiding the situation that the topological identification result is incorrect due to the too small target area, solving the problems of easy cross-station and unidentifiable existing electrical topology identification, and improving the accuracy of topological identification.
