Description

Technical Field

[0001] This invention relates to the field of power detection technology, and in particular to a method, device, equipment, and storage medium for locating electricity theft and leakage in power supply lines. Background Technology

[0002] Line loss refers to the loss of electrical energy at various stages during transmission and distribution. As enterprises develop towards lean manufacturing, higher requirements are placed on the amount of lost electricity and line loss. Meanwhile, increasingly sophisticated high-tech methods of electricity theft and meter tampering are putting higher demands on power companies for routine theft detection.

[0003] Meanwhile, with the development of urbanization, residents have put forward higher requirements for the surrounding living environment. They often hide low-voltage lines behind billboards or other obstructions. After a long period of operation, low-voltage lines often suffer from wear and tear, posing a significant safety hazard to the surrounding residents. Therefore, in order to ensure the safety of residents along the line, the power supply company has also put forward higher requirements for leak detection of power supply lines.

[0004] Currently, theft detection of power supply lines can only be carried out by checking the records of the electricity meter itself and the current and voltage information, which may result in errors and omissions, and the detection time is relatively long. On the other hand, leak detection of the line can only be carried out by working at height and measuring the current with a clamp meter. However, measuring with an ammeter requires workers to be in close contact with live parts and to work at height at the same time, which brings significant safety risks. Summary of the Invention

[0020] The first analog signal is located before the acquisition position, and the second analog signal is located after the acquisition position.

[0021] Furthermore, the results of locating electricity theft and leakage are determined based on the current signal, the first analog signal, and the second analog signal, including:

[0022] If the first analog signal is equal to the sum of the current signal and the second analog signal, then the result of the electricity theft and leakage location is determined to be no electricity theft or leakage.

[0023] If the first analog signal is not equal to the sum of the current signal and the second analog signal, then the current signal corresponding to the acquisition location is determined as the electricity theft location, and the electricity theft location is determined as the electricity theft leakage location result.

[0024] Secondly, embodiments of the present invention also provide a power supply line electricity theft and leakage location device, comprising:

[0025] The analog signal application module is used to apply a preset analog signal to the power supply line under test;

[0026] The signal acquisition module is used to acquire real-time analog signals in the power supply line under test, as well as the current signals corresponding to each meter in the power supply line under test.

[0027] The location result determination module is used to determine the location result of electricity theft and leakage based on real-time analog signals and various current signals.

[0028] Furthermore, if the real-time analog signal is acquired from an unloaded line segment, the positioning result determination module is specifically used for:

[0030] If the magnitude of the real-time analog signal is different from that of the preset analog signal, the acquisition location of the real-time analog signal will be determined as the location of electricity theft and leakage, and the location of electricity theft and leakage will be determined as the result of electricity theft and leakage location.

[0031] Furthermore, if the real-time analog signal is acquired from a loaded line segment, the location result determination module is specifically used for:

[0039] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions, which are used to cause a processor to execute the power supply line theft and leakage location method of any embodiment of the present invention.

[0040] This invention provides a method, apparatus, device, and storage medium for locating electricity theft and leakage in power supply lines. The method involves applying a preset analog signal to the power supply line under test; acquiring real-time analog signals from the power supply line and current signals corresponding to each meter in the power supply line; and determining the location of electricity theft and leakage based on the real-time analog signals and the current signals. By employing this technical solution, when it is necessary to locate electricity theft and leakage in a power supply line, a preset analog signal is applied to the power supply line under test. Then, by using the real-time analog signals acquired without contact and the current signals corresponding to the meters in the power supply line, the location of potential electricity theft or leakage problems in the power supply line under test can be located. This solves the problem that electricity theft and leakage inspections of power supply lines require climbing to heights and contacting live parts while the line is energized, leading to low safety. This allows power company personnel to locate the location of electricity theft or leakage problems in the power supply line under test in real time without contact or climbing, improving the safety of personnel. Furthermore, since climbing is no longer required, the time spent climbing is reduced, thus improving the overall efficiency of locating electricity theft and leakage in power supply lines.

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0050] Example 1

[0051] Figure 1 This is a flowchart of a method for locating electricity theft and leakage in power supply lines according to Embodiment 1 of the present invention. This embodiment of the present invention is applicable to situations where locations in power supply lines that may have leakage or electricity theft problems can be located without contact. This method can be executed by a power supply line electricity theft and leakage locating device, which can be implemented by software and / or hardware. The power supply line electricity theft and leakage locating device can be configured on a computer device, such as a laptop, desktop computer, or smart tablet.

[0052] like Figure 1 As shown in the figure, the method for locating electricity theft and leakage in power supply lines provided in this embodiment includes the following steps:

[0053] S101. Apply a preset analog signal to the power supply line under test.

[0054] In this embodiment, the power supply line under test can be specifically understood as a power supply line that needs to be detected for electricity theft and leakage. The preset analog signal can be specifically understood as a pre-processed and constructed continuously changing physical quantity that matches the electrical signal state in the power supply line under test, and the amplitude, frequency, or phase of the signal changes continuously with time.

[0055] Specifically, when it is necessary to detect electricity theft and leakage in the power supply line under test, the corresponding preset analog signal is generated by the analog signal generator based on the electrical signal status in the power supply line under test. The preset analog signal is then applied to the power supply line under test through the output of the meter at the transformer terminal in the power supply line under test, so that the preset analog signal and the electrical signal in the power supply line under test are transmitted synchronously.

[0056] In this embodiment of the invention, by applying a preset analog signal that is synchronously transmitted with the electrical signal in the power supply line under test to the power supply line under test, the testing personnel can clearly understand the transmission status of the synchronously transmitted electrical signal through the analog signal received wirelessly, and then test the power supply status of the power supply line under test based on the collected analog signal, thereby avoiding the safety risks caused by contact with live parts.

[0057] S102. Acquire the real-time analog signal in the power supply line under test, as well as the current signal corresponding to each meter in the power supply line under test.

[0058] In this embodiment, the real-time analog signal can be specifically understood as the intensity information of a preset analog signal at a corresponding location in the power supply line under test, collected in real time by a staff member using a handheld receiver while inspecting the line. The current signal can be specifically understood as the current signal flowing through the load at a location in the power supply line under test where a load is connected. The load is connected to the power supply line under test via a meter, and the current information read by the meter is the current signal flowing through the load.

[0059] Specifically, staff members use handheld receivers to patrol along the power supply line under test, receiving the corresponding real-time analog signals through the handheld receivers, and simultaneously reading the current signals corresponding to the loads connected to the power supply line under test via electricity meters during the patrol.

[0060] S103. Determine the location results of electricity theft and leakage based on real-time analog signals and various current signals.

[0061] Specifically, based on the status of the power supply line under test corresponding to the real-time analog signal acquisition location, when there is no load connected to the power supply line under test at the real-time analog signal acquisition location, the presence of electricity theft or leakage is determined solely based on the real-time analog signal. If electricity theft or leakage is found, the corresponding location is identified as the location of electricity theft or leakage. When there is a load connected to the power supply line under test corresponding to the real-time analog signal acquisition location, the presence of electricity theft or leakage is determined based on the current signal corresponding to the load and the real-time analog signal. If electricity theft or leakage is found, the corresponding location is identified as the location of electricity theft or leakage.

[0062] The technical solution of this embodiment applies a preset analog signal to the power supply line under test; acquires the real-time analog signal in the power supply line under test, as well as the current signal corresponding to each meter in the power supply line under test; and determines the location of electricity theft or leakage based on the real-time analog signal and the current signal. By adopting the above technical solution, when it is necessary to locate electricity theft or leakage in a power supply line, a preset analog signal is applied to the power supply line under test. Then, by using the real-time analog signal collected in the power supply line under test without contact, and the current signal corresponding to the meters in the power supply line under test, the location of potential electricity theft or leakage problems in the power supply line under test is located. This solves the problem that when inspecting power supply lines for electricity theft or leakage, it is necessary to climb to a height and contact live parts while the power is on, resulting in low safety. This allows power company personnel to locate the location of electricity theft or leakage problems in the power supply line under test in real time without contact or climbing, improving the safety of the personnel. Furthermore, since climbing is no longer required, the time spent climbing is reduced, thus improving the overall efficiency of locating electricity theft or leakage in power supply lines.

[0063] Example 2

[0064] Figure 2 This is a flowchart of a method for locating electricity theft and leakage in power supply lines according to Embodiment 2 of the present invention. The technical solution of this embodiment is further optimized based on the above-mentioned optional technical solutions. It generates a simulated signal according to the power grid operating frequency and synchronously couples the simulated signal with the electrical signal in the power supply line under test to generate a preset simulated signal to be applied to the power supply line under test. At the same time, it clarifies the method for determining the location of electricity theft and leakage when the real-time simulated signal is collected from a no-load line section and the method for determining the location of electricity theft and leakage when the real-time simulated signal is collected from a loaded line section. By judging the magnitude relationship between the real-time simulated signal and the preset simulated signal, and the magnitude relationship between the real-time simulated signal and the corresponding current signal of the meter, the location of electricity theft and leakage in different situations is determined respectively. In the absence of contact and climbing, the location of electricity theft or leakage in the power supply line under test is located in real time, which improves the safety of the staff. Since climbing is not required, the time required for climbing is reduced, and the overall efficiency of electricity theft and leakage location in power supply lines is improved.

[0065] like Figure 2 As shown in Embodiment 2 of the present invention, a method for locating electricity theft and leakage in power supply lines specifically includes the following steps:

[0066] S201. Generate a simulated signal based on the power grid operating frequency corresponding to the power supply line under test.

[0067] Specifically, in order for the analog signal applied to the power supply line under test to be used to characterize the transmission of electrical signals therein, the physical parameters such as frequency, waveform and phase of the input analog signal must be the same as the physical parameters of the corresponding electrical signal in the power supply line under test. Since the electrical signal in the power supply line under test is transmitted at the power grid operating frequency, an analog signal consistent with the power grid operating frequency can be generated.

[0068] Optionally, the frequency of the analog signal in this embodiment of the invention can be 50Hz, or it can be adaptively set according to the actual situation. This embodiment of the invention does not limit this.

[0069] S202. Synchronously couple the analog signal with the electrical signal in the power supply line under test.

[0070] Specifically, in order to ensure that the analog signal input to the power supply line under test is in phase with the electrical signal transmitted therein, the generated analog signal can be synchronously coupled with the electrical signal so that the two are transmitted at the same frequency and phase.

[0071] S203. Apply the synchronously coupled analog signal as a preset analog signal to the power supply line under test.

[0072] S204. Acquire the real-time analog signal in the power supply line under test, as well as the current signal corresponding to each meter in the power supply line under test.

[0073] S205. Determine whether the real-time analog signal is collected from an unloaded line segment. If yes, proceed to step S206; otherwise, proceed to step S209.

[0074] Specifically, if it is determined that the real-time analog signal is collected from a no-load line segment, then it is only necessary to consider whether the real-time analog signal is transmitted normally in the power supply line under test, and then step S206 is executed; if it is determined that the real-time analog signal is collected from a loaded line segment, then it is necessary to consider not only the real-time analog signal, but also the current signal corresponding to the meter closest to the real-time analog signal collection location, and determine whether there is a problem of electricity theft or leakage at the location corresponding to the meter by using the real-time analog signal and the current signal, and then step S209 is executed.

[0075] S206. Determine whether the magnitude of the real-time analog signal is the same as that of the preset analog signal. If yes, proceed to step S207; otherwise, proceed to step S208.

[0076] Specifically, since the preset analog signal should be propagated without loss in the same way as the electrical signal in the power supply line under test in the no-load section, that is, when there is no leakage or theft of electricity, the real-time analog signal collected should be the same as the preset analog signal applied to the power supply line under test. Therefore, when it is determined that the real-time analog signal and the preset analog signal are the same, step S207 is executed. Otherwise, it can be considered that there may be a problem of electricity theft or leakage at the collection location of the real-time analog signal, and step S208 is executed.

[0077] S207. The result of the electricity theft and leakage location is determined to be no electricity theft or leakage.

[0078] S208. The location of the real-time analog signal acquisition is determined as the location of electricity theft and leakage, and the location of electricity theft and leakage is determined as the result of electricity theft and leakage location.

[0079] Specifically, since the magnitude of the real-time analog signal is inconsistent with that of the preset analog signal, it can only be determined that there is power loss at the acquisition location of the real-time analog signal, but it is difficult to determine whether it is caused by leakage or theft. Therefore, the acquisition location of the real-time analog signal is directly determined as the location of theft and leakage, and the location of theft and leakage is determined as the result of theft and leakage.

[0080] S209. For the current signal corresponding to each meter, determine the first analog signal and the second analog signal that correspond to the current signal and are adjacent to the acquisition position of the current signal from the real-time analog signal.

[0081] In this configuration, the first analog signal is located before the acquisition position, and the second analog signal is located after the acquisition position. For example, Figure 3 This is an example diagram of signal acquisition for a power supply line under test provided in Embodiment 2 of the present invention, as shown below. Figure 3 As shown, for a line segment with a load, the load can be connected to the power supply line under test through a meter. The current signal read by the meter is determined as I2. The real-time analog signal collected by the staff with a handheld receiver before the meter connection point can be determined as the first analog signal I1. The real-time analog signal collected after the meter connection point can be determined as the second analog signal I3.

[0082] Specifically, the current signal corresponding to each meter can be understood as the current consumed by all loads connected to the power supply line under test through that meter. There may be electricity theft when each meter is connected. Therefore, for each meter, two real-time analog signals corresponding to its current signal and adjacent to the meter connection position can be obtained, and the two real-time analog signals can be determined as the first analog signal and the second analog signal, respectively.

[0083] S210. Determine the location result of electricity theft and leakage based on the current signal, the first analog signal, and the second analog signal.

[0084] Specifically, according to Kirchhoff's first law, the sum of the currents flowing into a node should be equal to the sum of the currents flowing out of the node. Taking the current signal acquisition location as a node, the first analog signal can be understood as the input current of the node, and both the current signal and the second analog signal can be used as the output current of the node. If no electricity theft has occurred, the first analog signal should be equal to the sum of the second analog signal and the current signal; otherwise, it can be considered that there may be electricity theft at the acquisition location. In this case, the electricity theft and leakage location result is determined based on the relationship between the first analog signal and the sum of the current signal and the second analog signal.

[0085] Furthermore, the determination of the electricity theft and leakage location results based on the current signal, the first analog signal, and the second analog signal can specifically include the following two situations:

[0086] S2101. If the first analog signal is equal to the sum of the current signal and the second analog signal, then the result of the electricity theft and leakage location is determined to be no electricity theft or leakage.

[0087] S2102. If the first analog signal is not equal to the sum of the current signal and the second analog signal, then the current signal corresponding to the acquisition location is determined as the electricity theft location, and the electricity theft location is determined as the electricity theft and leakage location result.

[0088] The technical solution of this embodiment generates an analog signal based on the power grid operating frequency, and synchronously couples the analog signal with the electrical signal in the power supply line under test to generate a preset analog signal to be applied to the power supply line under test. This allows the preset analog signal input to the power supply line under test to fully represent the loss state of the electrical signal in the line, improving the accuracy of determining and locating electricity theft and leakage. At the same time, based on the different locations of the real-time analog signal acquisition, the location of possible electricity theft and leakage problems in no-load and loaded line sections is determined based on the real-time analog signal, as well as based on the real-time analog signal and the current signal collected by the meter. This clarifies the location results of electricity theft and leakage under different conditions. The location of electricity theft or leakage problems in the power supply line under test can be located in real time without contact or climbing, improving the safety of the staff. Furthermore, since climbing is not required, the time required for climbing is reduced, thus improving the overall efficiency of locating electricity theft and leakage in the power supply line.

[0089] Example 3

[0090] Figure 4 This is a schematic diagram of a power supply line electricity theft and leakage location device provided in Embodiment 3 of the present invention. The power supply line electricity theft and leakage location device includes: an analog signal application module 31, a signal acquisition module 32, and a location result determination module 33.

[0091] The analog signal application module 31 is used to apply a preset analog signal to the power supply line under test; the signal acquisition module 32 is used to acquire the real-time analog signal in the power supply line under test, as well as the current signal corresponding to each meter in the power supply line under test; and the positioning result determination module 33 is used to determine the location result of electricity theft and leakage based on the real-time analog signal and each current signal.

[0092] The technical solution of this embodiment solves the problem that when inspecting power supply lines for electricity theft or leakage, it is necessary to climb to a height and contact live parts while the power is on, which leads to low safety. It enables power company staff to locate the location of electricity theft or leakage problems in the power supply line under test in real time without contact or climbing, which improves the safety of the staff. Furthermore, since climbing is no longer required, the time required for climbing is reduced, which improves the overall efficiency of locating electricity theft and leakage in power supply lines.

[0093] Furthermore, the analog signal application module 31 includes:

[0094] The signal generation unit is used to generate an analog signal based on the power grid operating frequency corresponding to the power supply line under test.

[0095] Synchronous coupling unit, used to synchronously couple analog signals with electrical signals in the power supply line under test;

[0096] The signal application unit is used to apply the synchronously coupled analog signal as a preset analog signal to the power supply line under test.

[0097] Furthermore, if the real-time analog signal is collected from an unloaded line segment, the positioning result determination module 33 is specifically used to: if the real-time analog signal is the same size as the preset analog signal, then determine the electricity theft and leakage positioning result as no electricity theft and leakage; if the real-time analog signal is different from the preset analog signal, then determine the collection location of the real-time analog signal as the electricity theft and leakage positioning location, and determine the electricity theft and leakage positioning location as the electricity theft and leakage positioning result.

[0098] Furthermore, if the real-time analog signal is collected from a loaded line segment, the positioning result determination module 33 is specifically used to: for the current signal corresponding to each meter, determine the first analog signal and the second analog signal that are adjacent to the current signal collection position from the real-time analog signal; determine the electricity theft and leakage location result based on the current signal, the first analog signal and the second analog signal; wherein, the first analog signal is located before the collection position and the second analog signal is located after the collection position.

[0099] The power supply line theft and leakage location device provided in this embodiment of the invention can execute the power supply line theft and leakage location method provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects of the execution method.
