[0027] In the description of the application, the meaning of "multiple" is at least two, for example two, three, etc., unless otherwise clearly and specifically limited. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back, top, bottom ...) are only used to explain the relative position relationship, motion situation, etc. between each component under a certain specific posture (as shown in the drawings). If this specific posture changes, this directional indication also changes accordingly. In addition, the terms "comprise" and "have" and any deformation thereof are intended to cover non-exclusive inclusion. For example, the process, method, system, product or equipment comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes the steps or units not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0028] In addition, references to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0030] Metering anomalies refer to suspected failures in electricity metering devices, potentially impacting metering accuracy and fair transactions between electricity suppliers and users. After a metering anomaly occurs, the metering team must search the electricity collection system for anomaly details, analyze parameters such as capacity, power, voltage, current, and power factor on a household-by-household basis, and conduct manual on-site investigations. Without the availability of relevant instrumentation for diagnostic assistance, collection anomalies require a manual household-by-household investigation into the causes of missed data collections and missing data. Manual dispatch and on-site processing are required, with no intelligent dispatching, remote diagnosis, or repair capabilities. This makes it difficult to quickly and accurately identify customers with metering anomalies and electricity theft, and impossible to navigate to the electricity metering device. Furthermore, manual on-site investigations and handling, as well as heightened work, have high error rates and pose personal safety risks such as electric shock and falls.

[0031] Based on big data technology and digital twin technology, and through the research and development ideas of Internet+, this application proposes a monitoring method for abnormal electricity metering.

[0032] Figure 1FIG. 1 is a flow chart of a method for monitoring abnormal energy metering according to an embodiment of the present application. The method for monitoring abnormal energy metering includes:

[0033] Step S101: Acquire user metering parameters collected by the electric energy metering device;

[0034] An electric energy metering device refers to a device used to measure electric energy, consisting of various types of electric energy meters or devices connected to voltage and current transformers (or dedicated secondary windings) and their secondary circuits. This includes electric energy metering cabinets (boxes, panels). Generally, electric energy metering devices can be smart meters. Electric energy metering devices can collect user metering parameters such as (positive and negative) active energy, voltage, current, and power, and send these collected user metering parameters to a monitor via a preset connection protocol. The monitor then verifies the user metering parameters, calculates energy consumption, and settles electricity bills.

[0035] Step S102: Compare the user metering parameters with the metering standards to screen out suspected abnormal users whose user metering parameters do not meet the metering standards;

[0036] Metering standards for various user types are pre-set, and the metering standards include at least the normal ranges of current, voltage, and active power for the three-phase current of various user types. User information for various user types is imported, and suspected abnormal users are automatically screened according to the entered metering standards on a daily basis. Specifically, when a user metering parameter is obtained, the metering standard corresponding to the user type to which the user metering parameter belongs is further determined, and the user metering parameter is compared with the metering standard. The user metering parameter that does not meet the metering standard is marked as a suspected abnormal metering parameter, and the user corresponding to the suspected abnormal metering parameter is marked as a suspected abnormal user.

[0037] Furthermore, according to the reasons why the user metering parameters of each suspected abnormal user are abnormal, an abnormal label of each suspected abnormal user is marked, and the abnormal label includes: abnormal power, abnormal voltage and current, abnormal power consumption, abnormal clock, and abnormal wiring.

[0038] Step S103: Analyze the user metering parameters of the suspected abnormal users based on a pre-established metering anomaly analysis optimization algorithm, and determine abnormal users and abnormal information of the abnormal users based on the analysis results, wherein the abnormal users are one or more of the suspected abnormal users.

[0039] During the work, it was found that among the suspected abnormal users of electricity metering, there are a large number of "false abnormal" users. For example, for abnormal users such as current loss and current imbalance, about 90% are false abnormalities caused by unbalanced on-site loads. Therefore, it is necessary to further screen the suspected abnormal users to accurately find the real abnormal users.

[0040] Based on a pre-established metering anomaly analysis optimization algorithm, the user metering parameters of suspected abnormal users are analyzed and compared to remove false anomalies, thereby identifying abnormal users from suspected abnormal users and marking abnormal information of abnormal users, where the abnormal information includes abnormality type, abnormality level, user address, collection point and other information.

[0041] Among them, the metering anomaly analysis optimization algorithm sets very precise anomaly judgment rules and judgment conditions based on user type and anomaly name. Based on the metering anomaly analysis optimization algorithm, it can realize accurate screening of user metering parameters of suspected abnormal users and screen out abnormal users.

[0042] Through the above steps, this embodiment performs an in-depth analysis on the suspected abnormal users initially screened out based on the metering anomaly analysis optimization algorithm to identify abnormal users, thereby achieving automatic and accurate screening of abnormal users, reducing labor costs, and improving work efficiency.

[0043] Figure 2 FIG. 1 is a flow chart of a method for monitoring abnormal energy metering provided by another embodiment of the present application. After step S103, the method further includes:

[0044] Step S1031: Generate an abnormal line graph based on the actual geographical location of the abnormal user, and display a metering abnormality management and control interface including the abnormal line graph through an application mobile handheld terminal or a web client.

[0045] Based on the actual geographic location of the abnormal users, the location of each abnormal user is marked on a map to generate an abnormal line map. In this embodiment, the location of the abnormal user's electric energy metering device is determined as the actual geographic location.

[0046] After identifying the abnormal user, the operating parameters, marketing identity document (ID), metering method, wiring method, and collection point information of the abnormal user are further obtained, and the number of abnormal users with the same abnormal tag is counted based on the marked abnormal tag. In addition, based on the abnormal level classification standard, the abnormal level of each abnormal user is determined. The scope of responsibility and affiliation between each operation and maintenance management department and each dedicated public transformer are set to quickly determine the operation and maintenance management part of the abnormal user, so as to avoid the incident of abnormal users being unmanaged or multiple people managing the same abnormal user, thereby improving the efficiency of abnormal user processing.

[0047] In this embodiment, different icons are used to respectively display the abnormality type, abnormality level, abnormality quantity, operating parameters, marketing ID, metering method, wiring method, user address, and collection point information. In this way, an abnormal line diagram including different information represented by different icons can be obtained.

[0048] Furthermore, a metering anomaly management and control interface including the abnormal line graphic is generated and displayed through an application (APP) mobile handheld terminal or a web client, so that operation and maintenance personnel can clearly understand the metering anomaly situation in the area under their jurisdiction from the metering anomaly management and control interface. The APP mobile handheld terminal can be a smart device with network connection function, such as a mobile phone or iPad, and the web client can be a computer, portable computer, etc.

[0049] This embodiment displays abnormal line graphics including abnormal user-related information on an APP mobile handheld terminal or a web client for operation and maintenance personnel to view, thereby realizing visual management of abnormal users and improving abnormal user management efficiency.

[0050] Figure 3 FIG. 1 is a flow chart of a method for monitoring abnormal energy metering provided by another embodiment of the present application. After step S103, the method further includes:

[0051] Step S1032: Send the abnormal information to the application mobile handheld terminal, and receive the abnormal user management result returned by the application mobile handheld terminal.

[0052] Assigning orders to the abnormal users: sending the abnormal information to the APP mobile handheld terminal, wherein the APP mobile handheld terminal is also connected to the metering abnormality troubleshooting instrument for communication, and the APP mobile handheld terminal performs abnormal user management after receiving the verification data uploaded by the metering abnormality troubleshooting instrument, and feeds back the abnormal user management results to the monitor.

[0053] In this embodiment, the APP mobile handheld terminal communicates with field equipment such as power metering devices and concentrators through infrared, power line carrier, and USB interfaces, obtains data stored in the power metering devices, and completes tasks according to the APP mobile handheld terminal functions. The information data and work completion status are then uploaded to the monitor through the interface, forming a seamless closed-loop management. Figure 4 , Figure 4 The figure shows a closed-loop management diagram of an APP mobile handheld terminal provided by an embodiment of the present application. Figure 4As shown, the APP mobile handheld terminal is connected to the password machine to implement password management for the APP mobile handheld terminal. The APP mobile handheld terminal is connected to the GIS (Geographic Information System) to use the GIS map to display the fault type, number, operation mark, and operator of abnormal users in each region, based on power supply areas at all levels and substations as dimensions. After integration, work orders are dispatched, indicating the last operation time, and regularly updating the progress and scope of abnormal processing.

[0054] The mobile app features include: remote automated order processing, SIM card fault detection, meter calibration, automatic access to meter reading schedules, on-site supplemental meter readings, cost-controlled power outage restoration, meter installation and replacement, on-site emergency repairs, automated workflow guidance, automatic log upload, and on-site audits. Using the app, maintenance personnel can conduct on-site operations and communicate with the monitoring system in real time.

[0055] When the monitor identifies an abnormal user, it will dispatch the abnormal user to the APP mobile handheld terminal in the corresponding area according to the abnormal user's geographical location, so that the operation and maintenance personnel can handle it in time.

[0056] In addition, the APP mobile handheld terminal is also connected to the metering anomaly troubleshooting instrument. The metering anomaly troubleshooting instrument uses a combination of 485 communication lines and Bluetooth to communicate with the electric energy metering device. Under the operation of on-site operation and maintenance personnel, it can obtain on-site user metering parameters collected by the electric energy metering device. After obtaining the on-site user metering parameters, the metering anomaly troubleshooting instrument verifies the error data in the electric energy metering device based on a preset error verification technology to obtain accurate user metering parameters, and uploads the accurate user metering parameters to the controller. With the assistance of the metering anomaly troubleshooting instrument, it can realize metering cross-household inspection, electric energy metering device fault detection, electricity theft investigation, online detection of harmonic content and operating conditions, online metering error detection, on-site photography and other functions.

[0057] The APP mobile handheld terminal receives the verification data uploaded by the metering anomaly troubleshooting instrument, performs abnormal user management, and feeds back abnormal user management results to the monitor, such as uploading supplementary copy data, uploading time calibration results, and feeding back on-site images.

[0058] This embodiment combines the online management of abnormal users with offline operations by assigning the abnormal users to the APP mobile handheld terminal and performing on-site inspections and abnormal management with the help of a metering abnormality troubleshooting instrument, thereby improving the efficiency of handling abnormal users.

[0059] Figure 5 FIG. 1 is a flow chart of a method for monitoring abnormal energy metering provided by another embodiment of the present application. After step S103, the method further includes:

[0060] Step S1033: obtaining positioning information collected by the electric energy metering device of the abnormal user, and determining a navigation route based on the positioning information, wherein the navigation route is used to accurately locate the electric energy metering device corresponding to the abnormal user.

[0061] There are a large number of electricity metering devices, with distribution points spread across many areas and a complex on-site environment. Manual memory of locations is inaccurate and time-consuming. There are also problems such as the inconsistency between the locations of some electricity metering devices and power supply points, unstable electronic distribution network map URLs, and inconsistency between power line maps and actual roads. These problems have seriously increased unnecessary workload and reduced work efficiency.

[0062] The electric energy metering device used in this embodiment includes a positioning platform. The positioning platform has functions such as real-time location storage, route intelligent navigation, storage of text and pictures, and confidential account sharing. It automatically locates the exact location during on-site inspection and processing, and can display reference objects such as large and small streets on the site and surrounding well-known buildings. It displays detailed path descriptions of the metering device ledger information, shortens the distance, reduces energy consumption, avoids congested and bumpy roads, reduces the chance of traffic accidents and vehicle damage, improves work safety, and improves the accuracy of the positioning of the electric energy metering device.

[0063] The monitor obtains the positioning information collected by the abnormal user's electricity metering device through a preset communication connection, determines the navigation route based on the positioning information, and can accurately locate the electricity metering device corresponding to the abnormal user, thereby improving the accuracy of positioning, reducing the difficulty of positioning, and helping to improve on-site processing efficiency.

[0064] Figure 6 FIG. 1 is a flow chart of a method for monitoring abnormal energy metering provided by another embodiment of the present application, wherein step S103 includes:

[0065] Step S10301: Determine the abnormal name to which the user metering parameter of the suspected abnormal user belongs based on a preset judgment rule and the user type of the suspected abnormal user;

[0066] User types include dedicated transformer users, public transformer users, and public-dedicated transformer users. Abnormalities typically include current loss, abnormal phase sequence, abnormal reverse power flow, and voltage loss. In a three-phase power supply system, all three phase currents and power values must meet requirements for stable power supply. Errors in one or more phases can lead to power supply anomalies.

[0067] For the suspected abnormal user whose user type is a dedicated transformer user, if the user metering parameters of the suspected abnormal user meet the first high supply and high metering rule or the first high supply and low metering rule, the abnormal name to which the user metering parameters of the suspected abnormal user belong is determined to be current loss; in addition, the dedicated transformer users with current loss do not include agricultural irrigation and drainage, and agricultural irrigation and drainage electricity users in poor counties.

[0068] Among them, the first high supply and high measurement rule includes: phase A is within the preset range and phase C is greater than the first current value, or phase C is within the preset range and phase A is greater than the first current value; the first high supply and low measurement rule includes: any one of the three-phase currents is within the preset range, and the sum of the other two phases is greater than the first current threshold; and / or any two phases of the three-phase current are within the preset range, and the current value of the other phase is greater than the second current threshold; wherein the preset range is 0-0.05A, the first current value can be 0.5A, the first current threshold can be 2A, and the second current threshold can be 1A.

[0069] For the suspected abnormal user whose user type is a dedicated transformer user, if the difference between the sum of the absolute values of the three-phase power and the absolute value of the total active power is greater than the preset power value, and the current value meets the preset requirements, then it is determined that the abnormal name of the user metering parameter of the suspected abnormal user is phase sequence abnormality;

[0070] Among them, the preset power value can be 10% of the total power of the three-phase current, the preset requirement can be that the current values of phase A and phase C are greater than 0.1, and the preset requirement can also be that the three-phase current is greater than 5% of the rated current, that is, 0.25A.

[0071] For the suspected abnormal user whose user type is non-photovoltaic user, if the total indication value of the low-voltage three-phase reverse active power is greater than the first preset indication value, the total indication value of the reverse active power of the dedicated public transformer is greater than the second preset indication value, the total indication value of the low-voltage single-phase reverse active power is greater than the third preset indication value, and the forward active power is 0, then it is determined that the abnormal name of the user metering parameter of the suspected abnormal user is reverse power abnormality; among which the user type of reverse power abnormality is all users, but photovoltaic users are excluded.

[0072] Among them, the first preset indication value may be 1, the second preset indication value may be 10, and the third preset indication value may be 1.

[0073] For the suspected abnormal user whose user type is a dedicated public transformer user, if the user metering parameter of the suspected abnormal user meets the second high supply high metering rule or the second high supply low metering rule, it is determined that the abnormal name to which the user metering parameter of the suspected abnormal user belongs is voltage loss.

[0074] The second high-supply high-voltage measurement rule is: the voltage of phase A or phase C is less than or equal to 70V and the sum of the voltages of phases A and C is less than 160V; or the current of any phase A, B, or C is greater than or equal to 5% of the maximum current. However, the situation where phases A and C are all zero is not included in the second high-supply high-voltage measurement rule. The second high-supply low-voltage measurement rule is: the voltage of phase A is less than 150V; and / or the voltage of phase B is less than 150V; and / or the voltage of phase C is less than 150V; or the current of any phase A, B, or C is greater than or equal to 5% of the maximum current. The second high-supply low-voltage measurement rule excludes the situation where phases A, B, and C are all zero.

[0075] In addition, for users with high supply and high metering and three-phase four-wire connection, if the rated voltage is 57.7V, when the voltage is lower than 70% and the current is greater than or equal to 5% of the maximum current, the missing items will be included in the analysis and judgment.

[0076] Step S10302: Counting the frequency of occurrence of the user metering parameters of the suspected abnormal user;

[0077] After determining the anomaly name to which the user metering parameters of suspected abnormal users belong, it is necessary to count the frequency of occurrence of the user metering parameters under this anomaly name on a daily basis. Understandably, if an anomaly only occurs once, it may be a coincidence and will not affect the collection of user metering parameters on that day or in subsequent periods. If an anomaly occurs multiple times, it is necessary to prioritize and conduct an anomaly investigation.

[0078] Step S10303: If the frequency meets the preset frequency requirement, the suspected abnormal user is determined to be an abnormal user, and abnormal information of the abnormal user is marked, where the abnormal information includes the abnormal name, the frequency, and the abnormal level.

[0079] In this embodiment, the preset frequency requirements corresponding to different abnormal names are different: the preset frequency requirement for current loss is three times or more per day; the preset frequency requirement for phase sequence abnormality is 24 times per day, and the reverse current abnormality meets the preset frequency requirement as long as it occurs once; the preset frequency requirement for voltage loss is more than three times per day.

[0080] If the frequency meets the preset frequency requirement, the suspected abnormal user is determined to be an abnormal user. The abnormal level of the abnormal user is recorded. Current loss, phase sequence abnormality, and voltage loss are all defaulted to level 1 events. For reverse power abnormality, the abnormal level is determined according to the different user types:

[0081] For low-voltage three-phase users: if the reverse active power is greater than or equal to 0.5, it is determined as a Level 1 event; if the reverse active power is greater than or equal to 0.5 and less than 1, it is determined as a Level 2 event; if the reverse active power is greater than or equal to 1 and less than 2, it is determined as a Level 3 event; other cases are Level 4 events.

[0082] For dedicated transformer users: if the reverse active power is greater than or equal to 0.2, it is determined as a Level 1 event; if the reverse active power is greater than or equal to 0.1 and less than 0.2, it is determined as a Level 2 event; if the reverse active power is greater than or equal to 0 and less than 0.1, it is determined as a Level 3 event; other cases are Level 4 events.

[0083] For low-voltage single-phase users: if the reverse active power is greater than or equal to 0.5, it is determined as a Level 1 event; if the reverse active power is greater than or equal to 0.1 and less than 0.5, it is determined as a Level 2 event; if the reverse active power is greater than or equal to 0 and less than 0.1, it is determined as a Level 3 event; other situations are Level 4 events.

[0084] In this embodiment, if the user metering parameters of a suspected abnormal user meet the judgment rules and the preset frequency requirements, it is determined to be an abnormal event, and if it responds continuously for 3 days during the abnormal time, it is converted into a historical abnormality.

[0085] Through the above steps, this embodiment determines abnormal events based on preset judgment rules and the frequency of occurrence of user metering parameters, implements secondary screening of suspected abnormal events, and improves the efficiency and accuracy of abnormal event identification.

[0086] Figure 7 FIG. 1 is a flow chart of a method for monitoring abnormal energy metering provided by another embodiment of the present application. After step S102, the method further includes:

[0087] Step S104: determining whether the suspected abnormal user is a suspected electricity theft user through the line loss and power load model library;

[0088] The electricity load model is mainly used to identify customers suspected of electricity theft with abnormal electricity metering.

[0089] Theoretical calculation values for 10kV line loss and 0.4kV substation line loss are set, and a library of power load models for different user types is established. Suspected abnormal users identified by the monitor are compared with the established power load models, 10kV line loss, and 0.4kV substation line loss, automatically identifying suspected electricity theft customers.

[0090] For the load model of a 10kV dedicated transformer municipal lighting customer, the system diagnosed a loss of current in phase B. By checking the power load model library and the marketing business system, it was found that this customer was a lighting user. During daytime hours, 6:00 AM to 7:00 PM, when all streetlights are turned off, a loss of current in phase B is normal. The load model for a 10kV dedicated transformer municipal lighting customer conforms to the following formula:

[0091] (1)

[0092] (2)

[0093] Among them, k is the coefficient; p is the instantaneous lighting power; P is the total lighting power of the time period.

[0094] Step S105: If the suspected abnormal user is a suspected electricity thief, the suspected electricity thief information of the suspected electricity thief is sent to the application mobile handheld terminal, so that the application mobile handheld terminal can feed back a suspected electricity thief confirmation result.

[0095] For suspected abnormal users, if the output result of the power load model library is a suspected electricity theft user, the suspected electricity theft user will be marked and a report will be sent to the APP handheld terminal for the operation and maintenance personnel of the APP mobile handheld terminal to verify the suspected electricity theft user and feed back the verification results to the monitor through the APP mobile handheld terminal.

[0096] In this way, suspected electricity thieves are identified based on the line loss and electricity load model library, which greatly saves manpower in tracking and screening suspected electricity thieves, improves the efficiency of identifying suspected electricity thieves, helps to recover power grid assets and eliminate electricity usage malpractices.
