[0033] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0034] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] Example 1

[0036] Figure 1 is a schematic diagram of the structure of a detection system for distinguishing household-to-transformer relationships based on carrier interference technology, provided in Example 1 of the present application. This embodiment of the present application is applicable to situations where power consumption detection is performed on a distribution network. The system can perform distribution network power consumption detection, i.e., a detection method for distinguishing household-to-transformer relationships based on carrier interference technology. The system can be implemented in the form of hardware and / or software, and the system can be configured in an electronic device that carries the function of detecting distribution network power consumption, i.e., distinguishing household-to-transformer relationships based on carrier interference technology.

[0037] Referring to FIG1 , a detection system for distinguishing household-to-substation relationships based on carrier interference technology includes: a first substation distribution network 100, a second substation distribution network 200, and a neutral line interferer 300; the first neutral line of the first substation distribution network 100 and the second neutral line of the second substation distribution network 200 are connected to the neutral line interferer 300.

[0038] Detection of household-to-substation relationships based on carrier interference technology can include power consumption detection devices detecting power consumption of individual lines in the distribution network and concentrators detecting power consumption of the regional distribution network. The power consumption detection devices can be configured to detect power consumption of individual lines. For example, the power consumption detection devices can be energy meters. The concentrators can be configured to detect power consumption in the regional distribution network. The concentrators can perform real-time, simultaneous meter readings for multiple power consumption detection devices. Both the power consumption detection devices and the concentrators utilize power carrier communication technology to detect power consumption. It can be understood that the power consumption detection devices and the concentrators achieve power consumption detection via power carrier communication. Alternatively, the concentrators can utilize a collection module to implement power carrier communication, while the power consumption detection devices can utilize a carrier module to implement power carrier communication. However, if power consumption detection utilizes power carrier communication, if there is a shared neutral or ground line between regional distribution networks, this can provide an information channel for power carrier communication, leading to confusion in meter readings for the concentrators. The concentrators may also have difficulty distinguishing between power consumption collection devices belonging to different power sources or regional distribution networks. At this point, the concentrator will collect electricity usage from other distribution networks, meaning that electricity usage from different distribution networks may be recorded cross-wise. Consequently, the electricity usage of the distribution networks detected by the concentrator is inaccurate. For example, as shown in Figures 2 and 3, to prevent transformer overvoltage damage, the neutral point of the transformer in the distribution network is grounded. As shown in Figure 4, the neutral point of the transformer in the distribution network is grounded, which creates a working grounding problem. Furthermore, to ensure the safe operation of the distribution network, the overhead lines in the distribution network may be double-grounded. Different distribution networks share a common ground wire, leading to cross-reading of electricity usage between distribution networks at different power sources. For example, the distribution network in distribution network A may record the energy meter of the distribution network in distribution network B, and the distribution network in distribution network B may also record the energy meter of the distribution network in distribution network A. This makes it difficult for the power supply station to verify the household transformers and can also cause anomalies in the line loss calculation of the distribution network. To address this situation, manual on-site meter verification is often employed to monitor actual power usage across multiple distribution networks. However, this method suffers from low efficiency and poor accuracy. Furthermore, the large number and complexity of distribution networks increases the burden of manual on-site meter verification.

[0039] The first substation distribution network 100 and the second substation distribution network 200 are different substation distribution networks. The power consumption detection equipment and concentrators between the first substation distribution network 100 and the second substation distribution network 200 both use power carrier communication to realize the power consumption detection of the substation distribution network. There is a shared neutral wire and / or shared ground wire between the first substation distribution network 100 and the second substation distribution network 200. For example, as shown in Figure 5, since the transformers of the adjacent substation distribution networks have the problem of neutral point grounding (i.e., working grounding), and the overhead lines passing through have the problem of repeated grounding of the neutral wire, a physical path for signal transmission can be provided for the concentrators of different substation distribution networks, which will cause the concentrators of the substation distribution networks to read the power consumption across substations.

[0040] The neutral line jammer 300 can be configured to block the power carrier information channel between adjacent distribution networks, that is, to block the transmission path of the power carrier signal between adjacent distribution networks. Optionally, the neutral line jammer 300 is a coil that can generate an oscillation frequency, and the oscillation frequency of the neutral line jammer 300 is the same as the frequency of the power carrier signal. Optionally, the neutral line jammer 300 can be connected to the first neutral line of the first distribution network 100 and the second neutral line of the second distribution network 200. It can be understood that the neutral line jammer 300 is connected in series with the neutral lines of the first distribution network 100 and the second distribution network 200. That is, the neutral line jammer 300 is connected in series to the portion of the distribution network that shares the neutral line. The first neutral line can be the neutral line in the first distribution network 100 that connects to the second distribution network 200; the second neutral line can be the neutral line in the second distribution network 200 that connects to the first distribution network 100. Optionally, the zero line jammer 300 can also be connected to the neutral point grounding (i.e., working ground) of the transformer or the repeated grounding of the line, that is, the zero line jammer 300 is connected in series to the part of the common ground wire in the distribution network. Thus, although there is a shared neutral wire and / or shared ground wire between the first substation distribution network and the second substation distribution network, there is no situation where the concentrator crosses the substation area to read the power consumption.

[0041] The technical solution of the embodiment of the present application is to set up a detection system for distinguishing household-to-substation relationships based on carrier interference technology, including: a first substation distribution network, a second substation distribution network and a zero line jammer; by setting a zero line jammer between the first substation distribution network and the second substation distribution network, the first zero line of the first substation distribution network and the second zero line of the second substation distribution network are connected to the zero line jammer. By accessing the zero line jammer, the signal transmission path between the first substation distribution network and the second substation distribution network is blocked, avoiding the cross-substation cross-recording of electricity consumption by the concentrator, realizing automatic detection of the actual electricity consumption of multiple substation distribution networks, solving the problem of low verification efficiency and poor accuracy of the detection method using manual on-site verification, and improving the efficiency and accuracy of distribution network electricity consumption detection; at the same time, due to the large number and complexity of the lines of the substation distribution network, the detection method of manual on-site verification increases the cost of manual on-site verification, and the detection of distribution network electricity consumption by using a detection system based on carrier interference technology to distinguish household-to-substation relationships also saves the labor cost required for on-site verification.

[0042] In an optional embodiment of the present application, the zero line interferer 300 includes an interference source generating component 310 and a frequency band extracting component 320 .

[0043] As shown in FIG6 , the zero line jammer 300 may include an interference source generating component 310 and a frequency band extraction component 320. The interference source generating component 310 may be configured to generate an interference source signal. Optionally, the interference source generating component 310 may be an oscillating circuit. The frequency band extraction component 320 is configured to extract an interference signal having the same frequency as the power carrier signal. Optionally, the interference signal may include interference noise having a signal-to-noise ratio (SNR) of 10 dB.

[0044] The zero-line jammer in this embodiment includes an interference source generating component and a frequency band extraction component. The interference source generating component realizes the generation of interference source signals, and the frequency band extraction component realizes the extraction of interference signals with the same frequency as the power carrier. By introducing the jammer signal, the signal transmission path between adjacent substation distribution networks is blocked, preventing the concentrator from reading power consumption across substations, and further improving the accuracy of power consumption detection in the substation distribution network.

[0045] In an optional embodiment of the present application, the zero line disruptor 300 further includes: a signal amplifying component 330 .

[0046] As shown in FIG7 , the zero line jammer 300 may further include a signal amplifying component 330 . The signal amplifying component 330 is configured to amplify the interference source signal. Optionally, the signal amplifying component 330 is connected after the interference source generating component 310 and before the frequency band extracting component 320 .

[0047] Exemplarily, as shown in FIG8 , the interference source generating component 310 may include a transformer 311 and an oscillating signal generating circuit 312 . The transformer 310 may be a 220V transformer. The oscillating signal generating circuit 312 may include a set of capacitors and resistors connected in series and parallel. The signal amplification component 330 may be a pre-amplification module configured to amplify the interference source signal. The frequency band extraction component 320 may include a mixing module 321 , an active bandpass filtering module 322 , a low-pass filter (LO) module 323 , and a frequency division module 324 . The mixing module 321 is configured to add interference noise in a frequency band close to the power carrier signal to the amplified interference source signal, thereby enhancing the interference capability of the zero line jammer. The active bandpass filter 322 is configured to filter out noise from the mixed signal to make the waveform of the mixed signal smoother. The low-pass filter module 323 is configured to eliminate interference from high-frequency noise above the cutoff frequency to eliminate glitches in the mixed signal and make the waveform smoother. The frequency division module 323 is configured to separate the interference signal in the same frequency band as the power carrier signal.

[0048] As shown in Figure 9, after the interference signal is added to the power carrier waveform, a sharp peak in amplitude is generated, thereby blocking the power carrier signal transmission path between distribution networks in different substations. Figure 10 shows a zoomed-in view of the center frequency after the addition of an interference signal with an SNR of -10dB. As shown in Figure 10, by periodically adding the interference signal, the interference signal blocking capability is guaranteed.

[0049] This solution achieves amplification of the interference source signal by accessing the signal amplification component, while also improving the accuracy of the frequency band extraction of the frequency band extraction component and improving the blocking capability of the interference signal generated by the zero line jammer.

[0050] In an optional embodiment of the present application, the system further includes: at least two phase line disruptors 400; a phase line disruptor 400 connected in parallel to the concentrator of the first substation distribution network 100; and a phase line disruptor 400 connected in parallel to the concentrator of the second substation distribution network 200.

[0051] As shown in Figure 11, the system also includes at least two phase line disruptors 400. Phase line disruptors 400 are configured to shield the power consumption detection devices of the distribution network to which they belong. Specifically, the phase line disruptors 400 are configured to block the power carrier communication channels of the power consumption detection devices of the distribution network to which they belong. Consequently, the power consumption detection devices cannot detect the power consumption of the various lines of the distribution network to which they belong. Simultaneously, the concentrator cannot read the meters of the power consumption detection devices of the distribution network to which they belong, thereby shielding the power consumption detection devices of the distribution network to which they belong. A phase line disruptor 400 is connected in parallel to the concentrator of the first distribution network 100; and a phase line disruptor 400 is connected in parallel to the concentrator of the second distribution network 200. For example, the colors of the three phase lines of the distribution network can be yellow, green, and red. Because the power consumption detection devices utilize power carrier communication, each power consumption detection device is connected to three phase lines. The phase line disruptors 400 can be connected in parallel to the phase lines of the distribution network to which they belong, or directly to the concentrator. Optionally, phase line jammers can be connected to all substation distribution networks. When it is necessary to shield the substation distribution network, the corresponding phase line jammer can be turned on to shield all power consumption detection equipment in the substation distribution network without power outage, prevent the operation of the carrier module of the power consumption detection equipment in the substation distribution network, shield the meter reading work of the substation distribution network, and implement signal interference with the substation distribution network, thereby ensuring normal power consumption detection of the substation distribution network without turning on the phase line jammer. Optionally, as shown in Figure 12, a phase line jammer can be incorporated into the substation distribution network that needs to be shielded, and the substation distribution network that needs to perform normal power consumption detection is not connected to the phase line jammer, so as to achieve shielding of all power consumption detection equipment in the substation distribution network without power outage, prevent the operation of the carrier module of the power consumption detection equipment in the substation distribution network, shield the meter reading work of the substation distribution network, and implement signal interference to the substation distribution network, thereby ensuring normal power consumption detection of the substation distribution network that is not connected to the phase line jammer, and blocking the power carrier communication from the dual perspectives of the neutral line jammer and the phase line jammer, thereby improving the blocking capability of the power carrier and thus improving the accuracy of power consumption detection of the substation distribution network.

[0052] This solution introduces at least two phase line jammers, with the phase line jammer connected in parallel on the concentrator of the first substation distribution network and the phase line jammer connected in parallel on the concentrator of the second substation distribution network. This achieves shielding of all power consumption detection devices in the substation distribution network without power outage, prevents the operation of the carrier module of the power consumption detection devices in the substation distribution network, shields the meter reading of the substation distribution network, and implements signal interference on the substation distribution network, thereby ensuring normal power consumption detection of the substation distribution network where the phase line jammer is not turned on. On the basis of blocking the signal transmission path between adjacent substation distribution networks, the power consumption detection devices of the substation distribution network that does not need to be detected are shielded, thereby avoiding the cross-substation power consumption reading of the concentrator, thereby improving the accuracy of power consumption detection in the substation distribution network.

[0053] In an optional embodiment of the present application, the phase line disrupter 400 includes a carrier generator 410 , a combined filter 420 and a wave blocker 430 .

[0054] As shown in Figure 13, the phase line jammer 400 may include a carrier generator 410, a combined filter 420, and a wave blocker 430. The carrier generator 410 is configured to generate an interference source signal with an oscillating frequency. The combined filter 420 is configured to filter out signals with different frequencies from the power carrier signal to obtain an interference signal with the same frequency as the power carrier signal. The wave blocker 430 is configured to block the power carrier signal of the phase line. A wave blocker interference device (i.e., a phase line jammer) is added to the three phases of the overhead line. The carrier generator 410 generates an interference source signal with an oscillating frequency. The combined filter 420 and the wave blocker 430 intercept the information channel of the power carrier, preventing the power carrier of the distribution network to which it belongs from reading the meter. Another distribution network in the ... As shown in Figure 15, after adding phase line jammers to the three phases of the overhead line, based on the characteristics of narrowband power line channels, the addition of phase line jammers can generate orthogonal frequency division multiplexing (OFDM) subchannels to block the communication channel of the concentrator's power carrier signal, thereby blocking the power carrier signal from meter reading. This allows the differentiation of household transformer relationships in different distribution networks without power outages.

[0055] The phase line jammer in this embodiment includes a carrier machine, a combined filter and a wave blocker. By blocking the communication channels of the power carrier signals of different phase lines, it is possible to distinguish the household-to-substation relationships of different distribution networks without power outages, thereby improving the accuracy of power consumption detection in the distribution networks of the substations.

[0056] In an optional embodiment of the present application, the phase line disrupter 400 further includes a coupling capacitor 440 .

[0057] As shown in Figure 16, the phase line disrupter 400 further includes a coupling capacitor 440. The coupling capacitor 440 is configured to amplify the interference signal.

[0058] This solution increases the blocking capability of the phase line jammer on the power carrier by adding a coupling capacitor to the phase line jammer and utilizing the signal amplification function of the coupling capacitor.

[0059] In an optional embodiment of the present application, the number of the phase line disruptor 400 of the first substation distribution network 100 is at least one.

[0060] The first substation distribution network 100 has at least one phase line disruptor 400. Accordingly, the second substation distribution network 200 also has at least one phase line disruptor. In actual overhead lines, due to the long length of actual power transmission and distribution lines, phase line disruptors 400 can be installed at locations with a preset line length. This ensures the phase line disruptor's ability to block power carrier signals. The preset line length can be a pre-set maximum line length at which a phase line disruptor 400 needs to be installed. The preset line length can be set and adjusted by technicians based on their experience.

[0061] 18 , a phase line disrupter 400 may include a carrier generator 410, a combined filter 420, a wave blocker 430, and a coupling capacitor 440. Two phase line disrupters may be included in the same phase line to ensure the phase line disrupter's ability to block power carrier signals.

[0062] In this embodiment, the number of phase line jammers in the first distribution network is at least one, which avoids the influence of the long line on the blocking ability of the phase line jammer on the power carrier signal, and ensures the blocking ability of the phase line jammer on the power carrier signal.

[0063] The detection system for distinguishing household-to-cell relationships based on carrier interference technology provided in the embodiments of the present application can execute the detection method for distinguishing household-to-cell relationships based on carrier interference technology provided in any embodiment of the present application, and has the corresponding functional modules and effects of the execution method.

[0064] Example 2

[0065] Figure 18 is a flow chart of a method for detecting household-to-transformer relationships based on carrier interference technology, provided in Example 2 of the present application. This embodiment of the present application is applicable to detecting power consumption in a distribution network. The method can be performed by a detection device for distinguishing household-to-transformer relationships based on carrier interference technology. The detection device for distinguishing household-to-transformer relationships based on carrier interference technology can be implemented in hardware and / or software. The detection device for distinguishing household-to-transformer relationships based on carrier interference technology can be configured in an electronic device that carries the function of detecting household-to-transformer relationships based on carrier interference technology.

[0066] Referring to FIG18 , a method for detecting household-to-household relationship based on carrier interference technology includes:

[0067] S1810. Turn on a neutral line jammer between the first substation distribution network and the second substation distribution network; wherein the neutral line jammer is used to block the power carrier information channel between the first substation distribution network and the second substation distribution network.

[0068] The zero line jammer can be used to block the power carrier information channel between adjacent distribution networks, that is, to block the transmission path of the power carrier signal between adjacent distribution networks. Optionally, the zero line jammer is a coil that can generate an oscillation frequency, see the above embodiment for details. The oscillation frequency is the same frequency as the power carrier signal. Optionally, the zero line jammer can be connected to the first zero line of the first distribution network and the second zero line of the second distribution network. It can be understood that the zero line jammer is connected in series with the zero lines of the first distribution network and the second distribution network. That is, the zero line jammer is connected in series to the part of the distribution network that shares the zero line. The first zero line can be the zero line in the first distribution network connected to the second distribution network; the second zero line can be the zero line of the second distribution network connected to the first distribution network 100. Optionally, the zero line jammer can also be connected to the neutral point grounding (i.e., working ground) of the transformer or the repeated grounding of the line, that is, the zero line jammer is connected in series to the part of the distribution network that shares the ground line. Therefore, even though there is a shared neutral line and / or a shared ground line between the first substation distribution network and the second substation distribution network, there is no situation where the concentrator reads electricity consumption across substations.

[0069] Optionally, a neutral line jammer between the first substation distribution network and the second substation distribution network may be turned on to block the power carrier information channel between the first substation distribution network and the second substation distribution network.

[0070] S1820: Perform power consumption detection on the second substation distribution network to obtain a power consumption detection result of the second substation distribution network.

[0071] The power consumption detection result of the second substation distribution network may be the actual power consumption of the second substation distribution network. The power consumption detection result of the second substation distribution network may be detected by a collection module of the concentrator.

[0072] Optionally, the collection module of the concentrator of the second substation distribution network can be used to detect the power consumption of the second substation distribution network to obtain the power consumption detection result of the second substation distribution network.

[0073] The technical solution of the embodiment of the present application is to turn on the neutral line jammer between the first substation distribution network and the second substation distribution network, and the neutral line jammer is used to block the power carrier information channel between the first substation distribution network and the second substation distribution network, and perform power consumption detection on the second substation distribution network to obtain the power consumption detection result of the second substation distribution network. By turning on the neutral line jammer, the signal transmission path between the first substation distribution network and the second substation distribution network is blocked, and the cross-substation reading of power consumption by the concentrator is avoided, and the actual power consumption of multiple substation distribution networks is automatically detected, thereby improving the efficiency and accuracy of distribution network power consumption detection and saving the labor cost required for on-site meter verification.

[0074] In an optional embodiment of the present application, before the power consumption detection is performed on the second substation distribution network, it also includes: turning on the phase line interferer in the first substation distribution network; the phase line interferer is used to shield the power consumption detection equipment of the first substation distribution network.

[0075] Phase line jammers can be used to shield the power consumption detection equipment of the distribution network in the substation area. In other words, the phase line jammer can be used to block the power carrier communication channel of the power consumption detection equipment in the substation area distribution network. As a result, the power consumption detection equipment cannot detect the power consumption of multiple lines in the substation area distribution network. At the same time, the concentrator cannot read the power consumption detection equipment in the substation area distribution network, thereby achieving shielding of the power consumption detection equipment in the substation area distribution network.

[0076] Optionally, before the power consumption detection is required for the second substation distribution network, the phase line jammer of the first substation distribution network can be turned on to shield the power consumption detection equipment of the first substation distribution network.

[0077] This solution shields the power consumption detection equipment of the first substation distribution network by turning on the phase line jammer in the first substation distribution network before detecting the power consumption of the second substation distribution network. This achieves the shielding of all power consumption detection equipment in the first substation distribution network without power outage, prevents the operation of the carrier module of the power consumption detection equipment in the first substation distribution network, shields the meter reading of the first substation distribution network, and achieves signal interference with the first substation distribution network, thereby ensuring the normal power consumption detection of the second substation distribution network without turning on the phase line jammer. On the basis of blocking the signal transmission path between the adjacent substation distribution networks, the power consumption detection equipment of the substation distribution network that does not need to be detected is shielded, thereby avoiding the cross-substation power consumption reading of the concentrator, thereby improving the accuracy of power consumption detection in the substation distribution network.

[0078] In an optional embodiment of the present application, after the power consumption detection of the second substation distribution network is performed to obtain the power consumption detection result of the second substation distribution network, it also includes: calculating the line loss of the second substation distribution network according to the power consumption detection result of the second substation distribution network; and optimizing the line of the second substation distribution network according to the line loss.

[0079] Optionally, the difference between the power consumption and power consumption detection results can be calculated based on the power consumption detection results of the second substation distribution network and the power supply of the second substation distribution network, and the difference can be determined as the line loss of the second substation distribution network. Based on the amount of line loss, the line of the second substation distribution network can be optimized to reduce the line loss of the second substation distribution network.

[0080] This solution detects the power consumption of the second substation distribution network, obtains the power consumption detection results of the second substation distribution network, and then calculates the line loss of the second substation distribution network based on the power consumption detection results of the second substation distribution network. According to the line loss, the lines of the second substation distribution network are optimized. By using the power consumption detection results of the second substation distribution network, the line loss calculation of the second substation distribution network is realized, which provides a basis for the optimization of the second substation distribution network.

[0081] In the technical solutions of the embodiments of this application, the acquisition, storage and application of the data involved comply with the provisions of relevant laws and regulations and do not violate public order and good morals.
