[0002] In the power grid system, the power transfer event can be used to accurately find the customer groups affected by the power transfer of the line, so as to notify these customers in a timely and accurate manner and improve customer satisfaction.

[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] The power supply transfer event determination method provided in this application can be applied to Figure 1 The application environment includes a computer device, which may be a terminal, and its internal structure diagram may be as shown in FIG. Figure 1 As shown. The computer device includes a processor, a memory, a communication interface, a display screen and an input device connected through a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, an operator network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a method for determining a power transfer event is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covered on the display screen, or a key, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse, etc.

[0059] The computer device may be a terminal, which obtains metering device information in the current power supply line, further determines the increase and decrease change information of the metering device in the current power supply line according to the metering device information, and thus determines whether there is a power transfer event in the current power supply line according to the increase and decrease change information. The terminal may be, but is not limited to, various personal computers, laptops, Internet of Things devices, etc.

[0060] In one embodiment, Figure 2 As shown, a method for determining a power transfer event is provided, and the method is applied to Figure 1 The computer device in the example is used to illustrate, including the following steps:

[0061] S201, obtaining metering device information in the current power supply line.

[0062] Among them, the metering devices include: electric energy meters, load management terminals, smart metering terminals, centralized meter reading data collection terminals, centralized meter reading concentrators, metering cabinets (meter boxes), voltage transformers, current transformers, test junction boxes and their secondary circuits, etc.; the metering device information may include the identification of the power supply line, the identification of the metering device and the correspondence between the date. For example, on November 19, 2021, there are metering devices 1 and 2 on power supply line 1; on November 21, 2021, there are metering devices 1, 2 and 3 on power supply line 1.

[0063] In this embodiment, the terminal can obtain the metering device information in the current power supply line at regular intervals or at a set time, for example, every 24 hours or at eight o'clock every morning; it can also trigger a corresponding acquisition instruction to obtain the metering device information in the current power supply line.

[0064] S202, determining the increase and decrease change information of the metering devices in the current power supply line according to the metering device information.

[0065] Among them, the increase and decrease change information refers to the addition of new metering devices or the reduction of metering devices in the current power supply line.

[0066] In this embodiment, the increase and decrease change information of the metering device in the current power supply line is determined according to the metering device information, and the increase and decrease change information can be determined according to the identification of the metering device in the power supply circuit every day. For example, on November 19, 2021, there are metering devices 1, 2, and 3 on the power supply line 1. If on November 21, 2021, there are metering devices 1, 2, 3, and 4 on the power supply line 1, the increase and decrease change information of the metering device in the power supply line 1 is increase; if on November 21, 2021, there are metering devices 1, 2, and 4 on the power supply line 1, the increase and decrease change information of the metering device in the power supply line 1 is increase of metering device 4 and decrease of metering device 3. If on November 21, 2021, there are metering devices 1 and 2 on the power supply line 1, the increase and decrease change information of the metering device in the power supply line 1 is decrease of metering device 3. If on November 21, 2021, there are metering devices 1, 2, and 3 on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 remains unchanged. Alternatively, the increase and decrease change information can also be determined based on the daily change in the number of metering devices in the power supply circuit. For example, on November 19, 2021, there are 5 metering devices on power supply line 1. If on November 21, 2021, there are 8 metering devices on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 is an increase; if on November 21, 2021, there are 4 metering devices on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 is a decrease; if on November 21, 2021, there are 5 metering devices on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 remains unchanged.

[0067] S203: Determine whether there is a power supply transfer event in the current power supply line according to the increase / decrease change information.

[0068] In this embodiment, it can be directly determined based on the increase and decrease change information whether there is an increase or decrease in the current power supply line, and then determine whether there is a power transfer event in the current power supply line. For example, on November 19, 2021, there are metering devices 1, 2, and 3 on power supply line 1. If on November 21, 2021, there are metering devices 1, 2, 3, and 4 on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 is that a metering device has been added, and it is determined that there is a power transfer event in power supply line 1. Alternatively, if on November 21, 2021, there are metering devices 1 and 2 on power supply line 1, then the increase and decrease change information of the metering devices in power supply line 1 is that a metering device has been reduced, then it is determined that there is a power transfer event in power supply line 1, and if the increase and decrease change information of the metering devices is unchanged, it is determined that there is no power transfer event in power supply line 1. It is also possible to determine that there are increased or decreased metering devices in the current power supply line based on the increase and decrease change information, and further determine whether there is a power transfer event in the current power supply line based on the source of the increased metering device or the destination of the reduced metering device. For example, for the newly added metering device 4, if the metering device 4 is transferred from other power supply lines to the power supply line 1, it is determined that there is a power transfer event in the power supply line 1, and if the metering device 4 is not transferred from other power supply lines to the power supply line 1, it is determined that there is no power transfer event in the power supply line 1. For the removed metering device 3, if the metering device 3 is transferred from the power supply line 1 to other power supply lines, it is determined that there is a power transfer event in the power supply line 1, and if the metering device 3 is not transferred from the power supply line 1 to other power supply lines, it is determined that there is no power transfer event in the power supply line 1.

[0069] In the above-mentioned power transfer event determination method, by obtaining the metering device information in the current power supply line, the increase and decrease change information of the metering device in the current power supply line is determined according to the metering device information, and further according to the increase and decrease change information, it is determined whether there is a power transfer event in the current power supply line. In the method of the present application, identification and judgment are performed based on the increase and decrease change information of the metering device. The method for obtaining the increase and decrease change information is simple, replacing the existing method of using the daily business category recorded by the medium-voltage distribution network system to identify the power transfer event. There is no need to redevelop a new interface module, the cost is low, and the power transfer event of the line can be obtained in time, thereby ensuring that the calculation of the line loss of the current power supply line is more accurate and improving customer satisfaction.

[0070] Above Figure 2 The embodiment introduces a method for determining a power transfer event. Next, the implementation process of determining whether a power transfer event exists according to the increase and decrease information is described in detail. Figure 3 As shown, the following steps are included:

[0071] S301, judging whether there is a newly added metering device in the current power supply line according to the increase and decrease change information.

[0072] In this embodiment, it is assumed that the current power supply line is power supply line 1, and there are 5 metering devices currently existing on power supply line 1, namely metering device 1, metering device 2, metering device 3, metering device 4, and metering device 5. If the increase and decrease change information of the metering device is to add 1 metering device, there are 6 metering devices currently existing on line 1, namely metering device 1, metering device 2, metering device 3, metering device 4, metering device 5, and metering device 6, and there is a newly added metering device 6 in power supply line 1; if the increase and decrease change information of the metering device is to add 1 metering device and reduce 1 metering device, there are 5 metering devices currently existing on power supply line 1, which may be metering device 1, metering device 2, metering device 3, metering device 4, and metering device 6, and there is a newly added metering device 6 in power supply line 1; if the increase and decrease change information of the metering device is unchanged, the metering devices currently existing on power supply line 1 are metering device 1, metering device 2, metering device 3, metering device 4, and metering device 5, and there is no newly added metering device in the current power supply line 1. If the increase or decrease change information of the metering device is to reduce one metering device, there are currently four metering devices on line 1, which can be any combination of metering device 1, metering device 2, metering device 3, metering device 4 and metering device 5. At this time, there is no new metering device in the front power supply line 1.

[0073] S302: If there is a newly added metering device in the current power supply line, determine whether there is a power transfer event in the current power supply line according to the metering device information and the newly added metering device.

[0074] In this embodiment, taking the above steps as an example, on November 24, 2021, there are metering devices 1, 2, 3, 4 and 5 in the power supply line 1. On November 26, 2021, there is a newly added metering device 6 in the current power supply line, and it is further determined whether there is a power transfer event in the current power supply line based on the metering device information and the newly added metering device 6. For example, when there is a newly added metering device in the current power supply line, it is also possible to further determine whether the number of metering devices in the current power supply line has changed, so as to determine whether only metering devices have been added to the current power supply line, or whether both new metering devices have been added and reduced, so as to determine whether there is a power transfer event in the current power supply line based on the newly added metering devices and the reduced metering devices.

[0075] The following describes the detailed implementation method of "determining whether there is a power supply transfer event in the current power supply line based on the metering device information and the newly added metering device" in two cases.

[0076] In the first case, the solution involves the case where there is a new metering device in the current power supply line. When the number of metering devices increases, it is determined whether there is a power transfer event in the current power supply line according to the source of the new metering device, such as Figure 4 As shown, the following steps are included:

[0077] S401: Determine whether the number of metering devices in the current power supply line increases according to metering device information.

[0078] In this embodiment, taking the above steps as an example, on November 24, 2021, there are metering devices 1, 2, 3, 4 and 5 in the power supply line 1, and on November 26, 2021, there is a newly added metering device 6 in the power supply line 1, and the metering devices 1, 2, 3, 4 and 5 in the power supply line 1 also exist, then on November 26, 2021, the number of metering devices in the power supply line 1 is increased. If on November 26, 2021, there is a newly added metering device 6 in the power supply line 1, and there are metering devices 1, 2 and 5 in the power supply line 1, then on November 26, 2021, the number of metering devices in the power supply line 1 does not increase.

[0079] S402: If the number of metering devices increases, determine whether the newly added metering devices are transferred from other power supply lines to the current power supply line.

[0080] In this embodiment, taking the above steps as an example, on November 26, 2021, a newly added metering device 6 exists in the power supply line 1, and the metering devices 1, 2, 3, 4 and 5 in the power supply line 1 also exist. If the metering device 6 exists in the power supply line 2 on November 24, 2021, it is determined that the newly added metering device 6 is transferred from the power supply line 2 to the power supply line 1; if the metering device 6 is not on any other power supply line on November 24, 2021, that is, on November 26, 2021, the metering device 6 is directly added to the power supply line 1, it is determined that the newly added metering device 6 is not transferred from other power supply lines to the power supply line 1.

[0081] S403: If the newly added metering device is transferred from another power supply line to the current power supply line, it is determined that there is a power transfer event in the current power supply line.

[0082] In this embodiment, taking the above steps as an example, the newly added metering device 6 is transferred from the power supply line 2 to the power supply line 1, and it is determined that there is a power transfer event in the power supply line 1.

[0083] S404: If the newly added metering device is not transferred from another power supply line to the current power supply line, it is determined that there is no power transfer event in the current power supply line.

[0084] In this embodiment, if the newly added metering device is not transferred from other power supply lines to the current power supply line, it means that the newly added metering device is directly added to the current power supply line. For example, on November 26, 2021, metering device 6 is added to power supply line 1, but metering device 6 is not on any other power supply line on November 24, 2021, that is, on November 26, 2021, metering device 6 is directly added to power supply line 1, then it is determined that the newly added metering device 6 is not transferred from other power supply lines to power supply line 1, and it is determined that there is no power transfer event in power supply line 1.

[0085] In the embodiment of the present application, it is determined whether the number of metering devices in the current power supply line has increased based on the metering device information. When the number of metering devices increases, and the newly added metering devices are transferred from other power supply lines to the current power supply line, it is determined that there is a power transfer event in the current power supply line. When the number of metering devices in the current power supply line increases, this method further determines whether the newly added metering devices are transferred from other power supply lines to the current power supply line, thereby determining whether there is a power transfer event. It only needs to obtain the source of the newly added metering devices to make the determination, and less information needs to be obtained, which improves the recognition efficiency.

[0086] The second situation: This solution involves the situation that there is a new metering device in the current power supply line, but the number of metering devices has not increased. Further, according to the source of the new metering device and / or the location of the removed metering device, it is judged whether there is a power transfer event in the current power supply line, such as Figure 4 As shown, the following steps are included:

[0087] S405: If the number of metering devices has not increased, determine whether the newly added metering devices are transferred from other power supply lines to the current power supply line, and / or whether the removed metering devices are transferred from the current power supply line to other power supply lines.

[0088] In this embodiment, when there is a newly added metering device in the current power supply line, but the number of metering devices in the current power supply line has not increased, it means that the current power supply line has both newly added metering devices and removed metering devices. Therefore, it is necessary to further determine the power supply line where the newly added metering device is located in the historical time period, so as to determine whether the newly added metering device is transferred from other power supply lines to the current power supply line, and / or determine whether the removed metering device is transferred to other power supply lines.

[0089] For example, on November 26, 2021, a new metering device 6 is added to power supply line 1, and metering device 1, metering device 2 and metering device 5 exist in power supply line 1. Then, on November 26, 2021, the number of metering devices in power supply line 1 has not increased. There may be the following situations. In the first situation, metering device 6 is transferred from other power supply lines to power supply line 1, and the removed metering device 3 and metering device 4 are transferred from power supply line 1 to other power supply lines 2 and power supply line 3 respectively, or to the same power supply line 2. It is also possible that one of metering device 3 or metering device 4 is transferred to other power supply lines, and the other is directly removed. In the second situation, metering device 6 is transferred from other power supply lines to power supply line 1, and metering device 3 and metering device 4 are directly removed from power supply line 1 without being transferred to any power supply line. In the third situation, metering device 6 is not Transferring from other power supply lines to power supply line 1 means directly adding a metering device to power supply line 1, and the removed metering device 3 and metering device 4 are respectively transferred from power supply line 1 to other power supply lines 2 and power supply line 3, or transferred to the same power supply line 2. It is also possible that one of the metering device 3 or the metering device 4 is transferred to other power supply lines, and the other is directly removed. In the fourth case, the metering device 6 is not transferred from other power supply lines to power supply line 1, but is directly added to the power supply line 1, and the metering device 3 and the metering device 4 are directly removed from the power supply line 1 and are not transferred to any power line.

[0090] S406: If the newly added metering device is transferred from other power supply lines to the current power supply line, and / or the removed metering device is transferred from the current power supply line to other power supply lines, it is determined that a power transfer event exists in the current power supply line.

[0091] In this embodiment, according to the above steps, the first case is that the newly added metering device 6 is transferred from other power supply lines to the current power supply line, and one of the removed metering devices 2 and 3 is transferred from power supply line 1 to other power supply lines, then there is a power transfer event in power supply line 1. The second case is that the newly added metering device 6 is transferred from other power supply lines to the current power supply line, and the removed metering devices 2 and 3 are not transferred to any power supply line, then there is a power transfer event in power supply line 1. The third case is that the newly added metering device 6 is not transferred from other power supply lines to the current power supply line 1, and one of the removed metering devices 2 and 3 is transferred from power supply line 1 to other power supply lines, then there is a power transfer event in power supply line 1.

[0092] S407: If the newly added metering device is not transferred from other power supply lines to the current power supply line, and the removed metering device is not transferred from the current power supply line to other power supply lines, it is determined that there is no power transfer event in the current power supply line.

[0093] In this embodiment, according to the above steps, it can be known that the fourth situation is that the newly added metering device 6 is not transferred from other power supply lines to the current power supply line 1, and the removed metering devices 2 and 3 are not transferred from power supply line 1 to other power supply lines, but are directly removed, then there is no power transfer event in the power supply line 1.

[0094] In an embodiment of the present application, when the number of metering devices has not increased, whether there is a power supply transfer event in the current power supply line can be determined by whether there are other power supply lines with newly added metering devices or removed metering devices. The information required by this method can be directly obtained without coordinating the resources of relevant departments, thereby reducing labor and financial costs.

[0095] Above Figure 4 The embodiment introduces the implementation process of determining whether there is a power transfer event in the current power supply line when the number of metering devices has not increased. Next, it focuses on two situations in which when there is no new metering device in the current power supply line, it is determined whether there is a power transfer event in the current power supply line based on whether the removed metering device exists in other power supply lines.

[0096] In the first case, the solution involves the case where there is no newly added metering device in the current power supply line, and the removed metering device is transferred from the current power supply line to another power supply line, then it is determined that there is a power transfer event in the current power supply line. Figure 5 As shown, the following steps are included:

[0097] S601: If there is no newly added metering device in the current power supply line, determine whether to remove the metering device in the current power supply line according to the metering device information.

[0098] In this embodiment, for example, the current power supply line is power supply line 1. On November 24, 2021, metering devices 1, 2, 3, and 4 exist in power supply line 1. If metering devices 1, 2, 3, and 4 still exist in power supply line 1 on November 26, 2021, the metering devices are not removed from power supply line 1. If metering devices 1 and 2 exist in power supply line 1 on November 26, 2021, metering devices 3 and 4 are removed from power supply line 1.

[0099] S602: If the removed metering device is transferred from the current power supply line to another power supply line, it is determined that there is a power transfer event in the current power supply line.

[0100] In this embodiment, taking the above steps as an example, if the removed metering device 3 and metering device 4 are simultaneously transferred from power supply line 1 to any one of the other power supply lines, it is determined that there is a power transfer event in power supply line 1. If the removed metering device 3 and metering device 4 are respectively transferred from power supply line 1 to different power supply lines 2 and 3, it is determined that there is a power transfer event in power supply line 1. If the removed metering device 3 is transferred from power supply line 1 to power supply line 2, and the metering device 4 is directly removed, it is determined that there is a power transfer event in power supply line 1.

[0101] The second case: if there is no newly added metering device in the current power supply line, and the metering device in the current power supply line has not been removed, it is determined that there is no power transfer event in the current power supply line.

[0102] In this embodiment, for example, in the above steps, the power supply line 1 has metering device 1, metering device 2, metering device 3 and metering device 4 on November 24, 2021 and November 26, 2021, and there is no new metering device in the power supply line 1, and the metering device is not removed, then it is determined that there is no power transfer event in the power supply line 1.

[0103] In the embodiment of the present application, if there is no newly added metering device in the current power supply line, it is determined whether there is a power transfer event in the current power supply line according to whether there is a removed metering device. This method determines whether there is a power transfer event in the identification line by detecting the removed metering device, and the method is convenient and simple.

[0104] The above embodiment introduces the specific steps of whether there is a power transfer event in the current power supply line when there is no newly added metering device. The following mainly introduces the corresponding relationship between the metering device information including the power supply line identification, metering device identification and date, and the implementation process of determining the increase and decrease change information of the metering device in the current power supply line according to the metering device information. Figure 6 As shown, the following steps are included:

[0105] S701, counting a first number of metering devices on a current power supply line on a current date according to a corresponding relationship; and a second number of metering devices on the current power supply line on a preset historical date.

[0106] In this embodiment, illustratively, if the current date is November 11, 2021, the current power supply line is power supply line 1, and there are metering devices 2, 3, 4, 6, 7, and 8 on power supply line 1; the historical date is November 9, 2021, and there are metering devices 1, 2, 3, 4, 5, 6, 7, and 8 on power supply line 1. The power supply line is identified as power supply line 1, and the metering devices are identified as metering device 1, metering device 2, etc. The dates are November 11, 2021 and November 9, 2021, respectively. According to the corresponding relationship, the first number of metering devices of power supply line 1 on November 11, 2021 is 6, and the second number of metering devices of power supply line 1 on November 9, 2021 is 8.

[0107] S702: Determine increase or decrease change information according to the first number and the second number.

[0108] In this embodiment, illustratively, the first number is 6, the second number is 8, and on November 9, 2021, the metering devices of the power supply line 1 are metering device 1, metering device 2, metering device 3, metering device 4, metering device 5, metering device 6, metering device 7, and metering device 8. If the metering devices of the power supply line 1 on November 11, 2021 are metering device 1, metering device 2, metering device 3, metering device 4, metering device 9, and metering device 10, then the increase and decrease change information of the power supply line 1 on November 11, 2021 is that two metering devices are added and four metering devices are reduced; if the metering devices of the power supply line 1 on November 11, 2021 are metering device 1, metering device 2, metering device 3, metering device 4, metering device 5, and metering device 6, then the increase and decrease change information of the power supply line 1 on November 11, 2021 is that 2 metering devices are reduced.

[0109] In the embodiment of the present application, the first number and the second number of metering devices of the current power supply line are counted according to the corresponding relationship, and the increase and decrease change information is determined according to the first number and the second number. The data acquisition in this method is simple, and the calculation method is simple and clear, which is more conducive to application in actual engineering.

[0110] Furthermore, if Figure 7 As shown, the power transfer event determination method also includes the following steps:

[0111] S801, obtaining metering device information in the current power supply line.

[0112] For example, if the current power supply line is a 10(6)kV line, the daily metering device information of the 10(6)kV line during the theoretical line loss calculation period is extracted. The metering device information includes the user number, metering point number, date, the line name of the metering device on this date, etc.

[0113] S802, counting a first number of metering devices on the current power supply line on the current date according to the corresponding relationship; and a second number of metering devices on the current power supply line on a preset historical date.

[0114] For example, the current date is day N, the preset historical date is day N-2, the number of metering devices on the current power supply line on day N is 3, and the number of metering devices on day N-2 is 5.

[0115] S803: Determine increase / decrease change information according to the first number and the second number.

[0116] For example, compared with day N and day N-2, the increase and decrease change information of the current power supply line on day N is a total reduction of two metering devices. It is possible that a new metering device is added to the current power supply line on day N, and three original metering devices are reduced.

[0117] S804, judging whether there is a newly added metering device in the current power supply line according to the increase and decrease change information, if yes, that is, there is a newly added metering device in the current power supply line, then executing step S805, if no, that is, there is no newly added metering device in the current power supply line, then executing step S808.

[0118] For example, compared with day N-2, the current power supply line added a new metering device on day N and reduced 3 original metering devices, so the current power supply line has a new metering device on day N.

[0119] S805, determining whether the number of metering devices in the current power supply line increases according to the metering device information, if yes, that is, the number of metering devices in the current power supply line increases, executing step S806, if no, that is, the number of metering devices in the current power supply line does not increase, executing step S807.

[0120] Exemplarily, compared with day N-2, the number of metering devices on the previous power supply line on day N is 3, and the number of metering devices on day N-2 is 5. If the number of metering devices on the current power supply line on day N does not increase, step S807 is executed.

[0121] S806, determining whether the newly added metering device is transferred from other power supply lines to the current power supply line, if yes, that is, the newly added metering device is transferred from other power supply lines to the current power supply line, then executing step S811, if no, that is, the newly added metering device is not transferred from other power supply lines to the current power supply line, then executing step S810;

[0122] S807, determine whether the newly added metering device is transferred from other power supply lines to the current power supply line, and / or whether the removed metering device is transferred from the current power supply line to other power supply lines. If so, that is, the newly added metering device is transferred from other power supply lines to the current power supply line, and / or, the removed metering device is transferred from the current power supply line to other power supply lines, then execute step S811; if not, that is, the newly added metering device is not transferred from other power supply lines to the current power supply line, and the removed metering device is not transferred from the current power supply line to other power supply lines, then execute step S810.

[0123] Exemplarily, a new metering device is added to the current power supply line on day N, and the newly added metering device is transferred from other power supply lines to the current power supply line, and the reduced metering device is not transferred from the current power supply line to other power supply lines, then step S811 is executed, that is, there is a power transfer event in the current power supply line.

[0124] S808, judging whether the metering device is removed from the current power supply line according to the metering device information, if yes, that is, the metering device is removed from the current power supply line, executing step S809, if no, that is, the metering device is not removed from the current power supply line, executing step S810.

[0125] S809, determine whether the removed metering device is transferred from the current power supply line to other power supply lines. If so, that is, the removed metering device is transferred from the current power supply line to other power supply lines, then execute step S811; if not, that is, the removed metering device is not transferred from the current power supply line to other power supply lines, then execute step S810.

[0126] S810: There is no power transfer event in the current power supply line.

[0127] S811, there is a power transfer event in the current power supply line.

[0128] In the embodiment of the present application, by obtaining the metering device information in the current power supply line, the increase and decrease change information of the metering device in the current power supply line is determined according to the metering device information, and further according to the increase and decrease change information, it is determined whether there is a power transfer event in the current power supply line. In the method of the present application, identification and judgment are performed based on the increase and decrease change information of the metering device. The method for obtaining the increase and decrease change information of the metering device is simple, replacing the existing method of using the daily business category recorded by the medium-voltage distribution network system to identify the power transfer event. There is no need to redevelop a new interface module, the cost is low, and the power transfer event of the line can be obtained in time, thereby ensuring that the calculation of the line loss of the current power supply line is more accurate and improving customer satisfaction.
