[0038] Example 1

[0039] Figure 1 This is a flowchart illustrating a power distribution line detection method according to Embodiment 1 of the present invention. This embodiment is applicable to situations involving the detection of power distribution lines. The method can be executed by a power distribution line detection device, which can be implemented in hardware and / or software and can be configured in electronic devices such as computers or servers. Figure 1 As shown, the method in this embodiment includes:

[0040] S110. Determine the first detection point and the second detection point located on both sides of the preset measurement point on the branch line to be tested, including the preset measurement point.

[0041] The branch line to be tested refers to a branch line within the distribution network of the transformer substation. Preset metering points can be set on the branch line to be tested. A preset metering point can be understood as a metering point pre-set for the branch line to be tested. The location of the preset metering point can be set based on experience in distribution network testing. The first testing point can be understood as a testing point set on the branch line to be tested, located to one side of the preset metering point. The first testing point can be a first preset distance from the preset metering point. The second testing point can be understood as a testing point set on the branch line to be tested, located to the other side of the preset metering point. The second testing point can be a second preset distance from the preset metering point. It should be noted that the first preset distance and the second preset distance can be the same or different.

[0042] Specifically, the location information of the detection points set for the branch line to be tested, including the preset metering point, is obtained. Based on this location information, the detection points of the branch line to be tested can be determined, namely, the first and second detection points located on both sides of the preset metering point on the branch line to be tested.

[0043] Optionally, determining the first and second detection points located on both sides of the preset metering point on the branch line to be tested, which includes the preset metering point, may include: determining each detection point on the power distribution line. This allows the detection points located on the branch line to be tested, including the preset metering point, to be determined based on the location information of each detection point, and used as candidate detection points. Then, two detection points located on both sides of the preset metering point can be selected from the candidate detection points, namely the first detection point and the second detection point.

[0044] S120. Determine the first current data and the second current data of the first detection point and the second detection point within the preset detection period, respectively.

[0045] The preset detection period can be understood as a pre-set time period for line detection of the branch line to be tested. It should be noted that the preset detection period can be set according to actual needs, and its value is not specifically limited here; for example, 10 minutes, 20 minutes, or 30 minutes, etc. In this embodiment of the invention, the method may further include: obtaining the preset detection period of the branch line to be tested in response to the detection period setting operation for the branch line to be tested. The detection period setting operation can be understood as an operation for setting the line detection period for the branch line to be tested. In this embodiment of the invention, the detection period can be flexibly set for the branch line to be tested through the detection period setting operation.

[0046] In this embodiment of the invention, the first current data can be understood as the current data obtained after collecting current data at the first detection point within a preset detection period. The second current data can be understood as the current data obtained after collecting current data at the second detection point within a preset detection period. Furthermore, to improve the accuracy of line detection, in this embodiment of the invention, before collecting current data at the first and second detection points, time synchronization can be performed using the BeiDou standard clock pulse signal. After time synchronization, synchronous current data can be collected at the first and second detection points respectively according to the same current sampling frequency.

[0047] Specifically, a detection period is preset, thus determining the preset detection period. After determining the preset detection period, current data at a first detection point during the preset detection period can be collected, i.e., first current data. Current data at a second detection point during the preset detection period can also be collected, i.e., second current data. In this embodiment of the invention, the current acquisition at the first detection point and the current acquisition at the second detection point can be obtained synchronously.

[0048] S130. Based on the first current data and the second current data, determine whether there is an abnormal line connection in the branch line to be detected.

[0049] Specifically, after obtaining the first current data and the second current data, the first current data and the second current data can be analyzed to obtain analysis results. Then, based on the analysis results, it can be determined whether there is any abnormal line connection in the branch line to be detected.

[0050] In this embodiment of the invention, determining whether there is an abnormal line connection in the branch line to be detected based on the first current data and the second current data may include: performing current attribute analysis processing on the first current data and the second current data respectively to obtain first current attribute information of the first current data and second current attribute information of the second current data; and then determining whether there is an abnormal line connection in the branch line to be detected based on the first current attribute information and the second current attribute information.

[0051] The first current attribute information can be understood as the current attribute information obtained after performing current attribute analysis on the first current data. The second current attribute information can be understood as the current attribute information obtained after performing current attribute analysis on the second current data. Optionally, the current attribute information may include at least one of current amplitude, current frequency, current phase, and current waveform.

[0052] In this embodiment of the invention, the current attribute analysis processing may include Fourier transform processing. Therefore, the first current data or the second current data can be subjected to Fourier transform processing according to the following formula:

[0053]

[0054] in, It can be represented as a DC current component, that is, the current component of the first current data or the second current data. w1 can be represented as the fundamental frequency. It can be represented as the phase of the fundamental component. t can be represented as time. m (m∈(2,n)) can be represented as the harmonic order. This can be represented as the current of the mth harmonic. φ m It can be represented as the current phase of the mth harmonic.

[0055] In this embodiment of the invention, determining whether an abnormal line connection exists in the branch line to be detected based on the first current attribute information and the second current attribute information may include: performing current attribute information analysis processing on the first current attribute information and the second current attribute information to obtain current attribute information analysis results. Then, based on the current attribute analysis results, it can be determined whether an abnormal line connection exists in the branch line to be detected.

[0056] Optionally, determining whether there is an abnormal line connection in the branch line to be detected based on the first current attribute information and the second current attribute information may include: determining the current change pattern of the branch line to be detected based on the first current attribute information and the second current attribute information; thereby, it is possible to determine whether there is an abnormal line connection in the branch line to be detected based on the current change pattern.

[0057] In this invention, determining the current variation pattern of the branch line to be detected based on the first current attribute information and the second current attribute information may include: generating a current waveform diagram of the branch line to be detected based on the first current attribute information and the second current attribute information; thereby, the current variation pattern of the branch line to be detected can be obtained based on the current waveform diagram.

[0058] Optionally, the current variation pattern may include a first current variation pattern at the first detection point and a second current variation pattern at the second detection point. Determining whether the branch line to be tested has an abnormal line connection based on the current variation pattern specifically includes: if the first current variation pattern and the second current variation pattern are consistent, it can be determined that the branch line to be tested does not have an abnormal line connection; if the first current variation pattern and the second current variation pattern are inconsistent, it can be determined that the branch line to be tested has an abnormal line connection.

[0059] The technical solution of this invention involves determining a first detection point and a second detection point located on both sides of a preset metering point on a branch line to be tested, including a preset metering point. This invention enables individual line testing of branch lines within a power distribution line by setting metering and detection points on the branch lines. Then, first current data and second current data are determined for the first and second detection points within a preset detection period. Based on the first and second current data, it is determined whether there is an abnormal line connection in the branch line to be tested, effectively identifying and accurately locating any abnormal lines in the power distribution line. This invention solves the technical problems of existing technologies' inability to accurately locate abnormal connection branches and the high cost of hardware equipment, enabling targeted line testing of power distribution line branches, improving the accuracy of abnormal line location, and reducing hardware equipment costs.

[0060] Example 2

[0061] Figure 2This is a flowchart illustrating a power distribution line detection method according to Embodiment 2 of the present invention. Optionally, based on the aforementioned embodiments, a metering meter is installed at the preset metering point. The method further includes: acquiring the metering meter's electricity consumption during a preset detection period; determining whether there is an abnormal line connection in the branch line to be detected based on the first current data and the second current data, including: determining the electricity consumption difference between the first detection point and the second detection point based on the first current data and the second current data; and determining whether there is an abnormal line connection in the branch line to be detected based on the metering meter's electricity consumption and the electricity consumption difference. Technical features that are the same as or similar to those in the above embodiments will not be repeated here.

[0062] like Figure 2 As shown, the method in this embodiment specifically includes:

[0063] S210. Determine a first detection point and a second detection point located on both sides of the preset metering point on the branch line to be tested, including the preset metering point, wherein a metering meter is installed at the preset metering point.

[0064] For example, a meter can be a 485 data acquisition meter.

[0065] S220. Determine the first current data and the second current data of the first detection point and the second detection point within the preset detection period, respectively.

[0066] S230. Obtain the electricity consumption of the meter during a preset detection period.

[0067] Specifically, the electricity consumption recorded by the meter at the preset metering point during the preset detection period is read, that is, the electricity consumption of the meter during the preset detection period is obtained.

[0068] S240. Based on the first current data and the second current data, determine the charge difference between the first detection point and the second detection point.

[0069] Specifically, a first electrical quantity at the first detection point is determined based on the first current data. A second electrical quantity at the second detection point is determined based on the second current data. The difference between the first and second electrical quantities is calculated to obtain the electrical quantity difference between the first and second detection points.

[0070] S250. Based on the meter reading and the difference in readings, determine whether there is an abnormal line connection in the branch line to be detected.

[0071] Specifically, the meter reading and the difference in readings are compared. If the meter reading and the difference in readings are the same, it can be determined that there is no abnormal line connection on the branch line to be tested. If the meter reading and the difference in readings are not the same, it can be determined that there is an abnormal line connection on the branch line to be tested.

[0072] Optionally, determining whether there is an abnormal line connection in the branch line to be tested based on the meter reading and the difference in readings can include: if the difference between the meter reading and the difference in readings does not exceed a preset error range, it can be determined that there is no abnormal line connection in the branch line to be tested. If the difference between the meter reading and the difference in readings exceeds the preset error range, it can be determined that there is an abnormal line connection in the branch line to be tested. The advantage of this approach is that it can improve the accuracy of abnormal line location.

[0073] For example, the first detection point is Figure 3 1, the second detection point Figure 3 In the second part, the preset measurement point is... Figure 3 3. To facilitate line testing, in this embodiment of the invention, the first and second testing points can be connected to the branch line to be tested respectively, making the testing operation of the power distribution line simple and convenient. Based on the above embodiments, the electricity meter can be read according to a preset time unit (e.g., minutes, hours, days, months) for electricity comparison and analysis.

[0074] Based on the above embodiments, the method may further include: calculating the current vector difference between the first current data and the second current data to obtain a calculation result. Then, based on the calculation result, the current direction and magnitude of the line located between the first detection point and the second detection point can be determined, so as to determine whether any external device is affecting the branch line under test.

[0075] The technical solution of this invention includes a metering device installed at a preset metering point. The metering device then collects the electricity consumption data during a preset detection period. Based on the first current data and the second current data, the electricity consumption difference between the first and second detection points can be determined. Furthermore, based on the metering data and the electricity consumption difference, it can be determined whether the branch line under test has any abnormal line access, thus realizing the function of determining whether there is abnormal access to a branch line through electricity consumption.

[0076] As an optional technical solution in an embodiment of the present invention, see [link to relevant documentation]. Figure 4This invention provides an optional distribution line detection device for installation on a branch line to be tested, comprising a first monitoring unit and two second monitoring units. The first monitoring unit can be installed at a preset metering point on the branch line to be tested, and can be used to acquire the electricity meter reading at the preset metering point. The two second monitoring units can be respectively installed at detection points on both sides of the preset metering point on the branch line to be tested, to collect current data on both sides of the preset metering point, i.e., first current data and second current data. Then, based on the first current data and the second current data, the electricity difference between the first detection point and the second detection point can be obtained. Therefore, based on the electricity difference and the electricity meter reading, it can be determined whether there is an abnormal line connection between the first detection point and the second detection point, i.e., whether there is an abnormal line connection on the branch line to be tested.

[0080] The technical solution of this invention, through a detection point determination module, determines a first detection point and a second detection point located on both sides of a preset metering point on a branch line to be tested, wherein the branch line to be tested is a branch line in the power distribution line of a transformer substation. This invention, by setting metering points and detection points on the branch lines in the power distribution line, enables individual line detection of the branch lines. A current data determination module determines the first current data and the second current data of the first and second detection points within a preset detection period, respectively. A line detection module, based on the first and second current data, determines whether there is an abnormal line connection in the branch line to be tested, effectively determining whether there is an abnormal line in the power distribution line and accurately locating it.
