[0051] Line loss is the power loss of the power grid. If there is a large amount of abnormal line loss in the power grid, it will cause great economic losses. Therefore, it is very necessary to deal with abnormal line loss in a timely and rapid manner. Therefore, how to avoid and quickly deal with abnormal line loss has become a technical problem that needs to be solved urgently by those skilled in the art.
[0052] In order to solve the above technical problems, an embodiment of the present application provides a method for handling abnormal line loss. In this method, after determining that the power grid line loss is abnormal, the line loss abnormality is located, and the steps of determining whether the file is abnormal and determining whether the collection is abnormal are performed. If the file is abnormal, a first abnormal work order is generated according to the abnormal file details. If the collection is abnormal, a second abnormal work order is generated.

[0053] Figure 1 The flowchart of a method for handling abnormal line loss according to some embodiments is exemplarily shown. The method includes S100-S900.
[0054] S100: Determine whether the power grid line loss is abnormal.
[0055] In the embodiment of the present application, abnormal line loss refers to a situation in which the line loss exceeds the normal range or expected value during the power transmission and distribution process.
[0056] In some embodiments, the step of determining whether the grid line loss is abnormal includes: light load determination.
[0057] Light load determination can be made according to the monthly light load determination rules or according to the daily light load determination rules.
[0058] The rules for identifying monthly light loads include line light loads and substation light loads; line light loads include line loss rates greater than or equal to 7% or less than -2%, the absolute value of daily line loss electricity is greater than the value of the feeder gateway meter multiplier multiplied by 0.01 kWh, and the monthly electricity is less than 5,000 kWh, which is considered light load. Substation light loads include daily electricity corresponding to the transformer's daily electricity consumption being less than 30% of its rated capacity (power factor is calculated as 0.8, and daily is calculated as 24 hours), and the monthly electricity consumption is less than 3,000 kWh, which is considered light load for the transformer.
[0059] The daily light load identification rules include: taking the total active power and total reactive power of the line gateway table to calculate the load rate at each 15-minute point, and taking the maximum load rate of the day as the daily load for judgment. If the daily load rate is less than 10%, it can be judged as a light-load line, and the line loss is determined to be abnormal. The 10% threshold is adjustable.
[0060] S200: If the line loss is normal, archive the data.
[0061] In the embodiment of the present application, if the line loss is not abnormal, the judgment result is archived for subsequent use.
[0062] S300: If the line loss is abnormal, determine whether the file is abnormal.
[0063] In the embodiment of the present application, since abnormal line loss will cause many losses, after determining the abnormal line loss, the abnormal position is located, so that the location where the problem occurs can be processed later. First, it can be determined whether the file is abnormal. In some cases, the abnormal line loss may be caused by problems with the file, so in the embodiment of the present application, it is determined whether the file is abnormal.
[0064] In addition, in some embodiments, if the line loss is abnormal, an abnormal work order can be directly generated, and grassroots staff can handle the line loss abnormality according to the abnormal work order.
[0065] In some embodiments, the step of determining whether the file is abnormal includes:
[0066] Determine whether the electricity customer information, metering point information, substation information, line section information, 10kV line file and substation basic file are abnormal respectively; if the electricity customer information, metering point information, substation information, line section information, 10kV line file and / or substation basic file are abnormal, determine that the file is abnormal; if the electricity customer information, metering point information, substation information, line section information, 10kV line file and substation basic file are not abnormal, determine that the file is not abnormal.
[0067] In the embodiment of the present application, the abnormality of the file is judged by using a variety of information, so that the judgment result can be more accurate.

[0069] Get user profile;
[0070] Determine whether there are differences and omissions in the user category, operating status, voltage level, electricity consumption category, industry classification, contract capacity, operating capacity, fee control mode and power source type in the user profile.
[0071] If there are differences and / or omissions, it is determined that the user customer information is abnormal;
[0072] If there are no differences or omissions, it is determined that the user customer information is not abnormal.

[0078] Industry classification can specifically determine whether the industry classification in the customer file is accurate, such as manufacturing, service, agriculture, etc. Check whether there is an error in industry classification or no subdivision.
[0079] Contract capacity and operating capacity: Specifically, it can determine whether the contract capacity in the customer file is consistent with the actual operating capacity. Check whether there is a large capacity difference or failure to update in time. For customers who change capacity, verify whether the change procedures are complete and compliant.
[0080] The fee control mode can specifically determine whether the fee control mode information in the customer file is accurate, such as prepaid, postpaid, etc. Check whether the fee control mode is consistent with the actual charging method, and whether there is any improper fee control strategy setting.
[0081] The power type can be used to determine whether the power type information in the customer file is accurate, such as mains power, self-provided power, etc. Check whether the power type is consistent with the actual power supply.
[0082] Discrepancies usually refer to inconsistencies between the information in the archives and the actual situation or other related records. Missing refers to the situation where some necessary information in the archives is not recorded or omitted.
[0083] In some embodiments, the step of determining whether the metering point information is abnormal includes:
[0084] Obtain metering point archives;
[0085] Determine whether there are any differences or omissions in the metering point name, metering point status, metering point voltage level, electricity consumption category, metering point category code, PT, CT, metering point usage code, station area identification and line section identification in the metering point file;
[0086] If there is a difference and / or a missing, determining that the metering point information is abnormal;
[0087] If there is no difference or missing, it is determined that the metering point information is not abnormal.

[0100] Determine whether there are any differences or omissions in the substation name, substation operation status, power supply unit code and substation type in the substation file;
[0101] If there is a difference and / or a lack, determining that the station area is abnormal;
[0102] If there is no difference and no missing, it is determined that the station is not abnormal.
[0103] In the embodiment of the present application, the substation number is used as the unique identification code, and the substation files are checked for differences and omissions according to the substation name, substation operation status, power supply unit code, and substation type. Statistics are collected and details are drilled in the form of province, bureau, and institute. Abnormal analysis and statistics are conducted on the substations that affect the accurate calculation rate of line loss in the same period.
[0104] The specific name of the station area can be compared with the name in the station area file with the actual site or related records to check whether there are any inconsistencies or errors.
[0105] Status verification can specifically check whether the operating status of the substation is consistent with the actual situation, for example, whether there is a substation that is incorrectly marked as "normal" but is actually in a "faulty" state.
[0106] The specific code of the power supply unit can determine whether each substation is correctly assigned to the corresponding power supply unit and the code is accurate.
[0107] The substation type can be used to check whether the substation type is consistent with its actual use. For example, an industrial substation should not be mistakenly classified as a residential substation.
[0108] Discrepancies may include data mismatches, inconsistencies or redundancies, while missing data may mean that certain key fields or information were not recorded or updated.
[0109] In some embodiments, the step of determining whether the line segment is abnormal includes:
[0110] Get the route segment file;
[0111] Determine whether there are any differences or omissions in the line name, line operation status, line voltage level, line category, line type, segmentation mark, superior mark, subordinate mark and ownership in the line file;
[0112] If there is a difference and / or a missing, determining that the route segment is abnormal;

[0116] The line operation status can specifically determine whether the line operation status is consistent with the actual situation, such as in operation, under maintenance, or out of service.
[0117] The line voltage level can be specifically judged by focusing on comparing the 10kV voltage level lines to ensure that its information is accurate and consistent with the marketing data.
[0118] The line category can be specifically judged based on the purpose and nature of the line, and the classification can be checked to see if it is accurate.
[0119] The line type can specifically determine whether the line type (such as overhead lines, cables, etc.) is consistent with the actual situation.
[0120] The segmentation mark can specifically determine whether the segmentation mark of the line is set correctly and whether it is consistent with the actual segmentation situation.
[0121] Superior and subordinate identification: It can be used to determine whether the superior and subordinate relationship identification of the line is accurate, ensuring that the hierarchical relationship between the lines is clear.
[0122] Ownership: It can determine the ownership of the line in detail and check whether there are any unclear or incorrect ownership issues.
[0123] During the investigation, we focus on whether there are discrepancies and omissions in the line files. Differences may be manifested as inconsistent data, contradictory information, etc.; omissions may be manifested as blank key fields, information not entered, etc.
[0124] In some embodiments, the step of determining whether the 10 kV line file is abnormal includes: using the model generation rules of 10 kV and below feeders to check the 10 kV line file.
[0125] In the embodiment of the present application, the 10kV feeder model plays a vital role in the power system and is the basis for power system analysis, design, operation and control. This model is mainly used to describe the electrical characteristics, operating status and interaction with other system components of the 10kV feeder. Data is required when generating the model of 10kV and below feeders. The source of this data is the 10kV line archive, so the model generation rules can be used to check the 10kV line archive.
[0126] In some embodiments, the step of determining whether the basic file of the station area is abnormal includes: using the station area model to generate rules and verify the basic file of the station area.
[0127] In the embodiment of the present application, the substation model is a tool used in the power system to describe and manage the operation of the substation (i.e., the power supply range of the distribution transformer). Mainly through the real-time collection, processing and analysis of the power consumption data of the substation, the accurate measurement of the power consumption of the substation is achieved, providing strong support for the operation and management of the power system. When generating the substation model, data is required, and the source of these data is the basic files of the substation, so the basic files of the substation can be checked using the substation model generation rules.
[0128] S400, if the file is abnormal, determine the abnormal details of the file;
[0129] S500, generating a first abnormal work order according to the abnormal file details;
[0130] In the embodiment of the present application, when it is determined that the file is abnormal, the abnormal file details are obtained. According to the first abnormal work order generated by the abnormal file details, the abnormality can be directly located to determine the content in the file that may cause abnormal line loss.
[0131] S600: Determine whether collection is abnormal.
[0132] In the embodiment of the present application, the abnormal line loss may be caused by file abnormality or a problem in the collected data, so the collection abnormality is also judged.
[0133] In some embodiments, the step of determining whether collection is abnormal includes:
[0134] Collect abnormal messages.
[0135] Analyze the abnormal message to obtain an analysis result;
[0136] If the analysis result includes message truncation, communication timeout and / or continuous offline, determining that the collection is abnormal;
[0137] If the analysis result does not include message truncation, communication timeout and continuous offline, it is determined that the acquisition is not abnormal.
[0138] S700: If the collection is abnormal, generate a second abnormal work order.
[0139] In the embodiment of the present application, if the collection is abnormal, the corresponding equipment, time and abnormal description list are provided, and a second abnormal work order is generated based on the equipment, time and abnormal description list. In this way, the grassroots operator can check the collection process according to the second abnormal work order to eliminate the error of abnormal collection.
[0140] S800. If the data collected is normal, check for voltage abnormality, low voltage, current loss and reverse polarity to divide the on-site inspection level.
[0141] In the embodiment of the present application, if the acquisition is not abnormal, the situation causing abnormal line loss may be an on-site problem. Therefore, in the embodiment of the present application, voltage abnormality, low voltage, current loss and reverse polarity are checked, and the on-site inspection level is divided.
[0142] In some embodiments, the step of checking the voltage anomaly includes:
[0143] If the voltage of any phase A, B, C of the three-phase four-wire high-supply high-meter or high-supply low-meter electric energy metering device is lower than 85% of the rated value or higher than 250V for 10 times or more in a day, it is determined that there is a voltage abnormality;
[0144] If the voltage of any phase of a three-phase three-wire high-supply and high-meter electric energy metering device is lower than 90% of the rated value for 10 times or more in a day, it is determined that there is a voltage abnormality.
[0145] In the embodiment of the present application, when the line loss is abnormal, the voltage of the electric energy metering device under the line or substation is checked to see if there is a loss of voltage, undervoltage or overvoltage. In some embodiments, before executing the step of checking the voltage anomaly, factors such as low voltage caused by data quality, fault repair, power shortage or long power supply radius are eliminated, so that the verification result can be more accurate.
[0146] In some embodiments, the step of checking the low voltage includes: according to the system substation low-voltage electricity consumption monitoring function, setting the substation low-voltage users as low-voltage monitoring points, analyzing the voltage characteristics of the line / substation user group, and observing the voltage data changes, so as to accurately detect single metering failures, or voltage drops caused by heating of the grid line.
[0147] In some embodiments, the step of checking the flow loss comprises:
[0148] If the current of any phase of A, B, and C on that day is 0, and the primary side current value of the phase line with the largest power consumption exceeds a predetermined threshold within a certain period of time, it is determined that there is a current loss.
[0149] In the embodiment of the present application, when the line loss is abnormal, the line is checked and the electric energy metering device is checked in the substation to see if there is a current loss. Before executing the step of checking the current loss, it also includes: eliminating data quality and customer phase loss operation factors.
[0150] In some embodiments, the step of checking the reverse polarity includes:
[0151] If at the same time point in a three-phase four-wire high-supply low-meter electric energy metering device, the sum of the absolute values of the active power of phases A, B, and C and 50% of the difference between the total active power is equal to the active power of one of the three phases A, B, and C, then reverse polarity is determined to exist.
[0152] In the embodiment of the present application, the on-site inspection levels are divided according to the inspection results of voltage anomalies, low voltage, current loss and reverse polarity.
[0153] In the embodiment of the present application, the weights of the verification results corresponding to different items can be set, and the on-site verification level can be calculated in combination with the above verification results. The on-site verification level can be used to evaluate the risk level. The higher the risk level, the greater the probability of problems and failures, and the more attention it needs to be paid.
[0154] S900. Generate a third abnormal work order according to the on-site inspection level.
[0155] In an embodiment of the present application, a third abnormal work order is generated according to the on-site verification level, and the risk level can be clearly stated on the third abnormal work order. The higher the risk level of the third abnormal work order, the more it needs to be processed quickly by grassroots operators.
[0156] In some embodiments, the method further comprises:
[0157] When receiving a message generated after the problem is solved based on the first abnormal work order, the second abnormal work order and the third abnormal work order, re-execute the step of determining whether the power grid line loss is abnormal;
[0158] If the line loss is not abnormal, re-save the file.
[0159] In the embodiment of the present application, after the problem causing the abnormal line loss is processed, the step of determining whether the grid line loss is abnormal is re-executed, and after determining that the line loss is not abnormal, the data is archived.
[0160] In the above embodiment, a method for handling abnormal line loss is provided. In this method, after determining that the power grid line loss is abnormal, the line loss abnormality is located, and the steps of determining whether the file is abnormal and determining whether the collection is abnormal are performed. If the file is abnormal, a first abnormal work order is generated according to the abnormal file details. If the collection is abnormal, a second abnormal work order is generated. If the collection is not abnormal, the voltage abnormality, low voltage, loss of current and reverse polarity are checked, and the on-site verification level is determined. A third abnormal work order is generated according to the verification level, so that grassroots staff can quickly handle the line loss abnormality after locating it.
