Description

Technical Field

[0001] This application relates to the technical field of power systems, and particularly to a line loss judgment method, device, computer device, storage medium, and program product. Background Art

[0002] The line loss of a line is not only a standard for evaluating whether the line management of a power enterprise is in place, but also determines whether the power enterprise needs to invest a large amount of manpower and material resources. When judging the line loss of a line, a line loss rate between -2% and 5% is regarded as normal, otherwise it is abnormal. There may be the following situations. The inherent line loss rate of a line is 0.1%. At this time, there are already problems such as power theft, metering device failure, and wrong archive data on the line, but the obtained line loss rate is still 4%, which is within the judgment condition of -2% to 5%, so it is regarded as normal, resulting in an overly long abnormal survival time, which brings great inconvenience and workload to subsequent processing. It is also possible that the inherent line loss rate of the line is 3.5%. At this time, the line is in a normal situation, but the obtained line loss rate is 6%, exceeding the judgment condition and being regarded as abnormal. Therefore, when judging line loss based on the default value of the industry standard, there is a problem of inaccurate judgment. Summary of the Invention

[0066] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to 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.

[0067] The line loss judgment method provided by the embodiments of the present application can be applied to, for example Figure 1 the application environment shown. The application environment may include a computer device, and the computer device may be a server, and its internal structure diagram may be as Figure 1 shown. The computer device includes a processor, a memory and a network interface 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, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used to store relevant data of line loss. The network interface of the computer device is used to communicate with an external terminal through a network connection. The computer program, when executed by the processor, implements a line loss judgment method. Among them, the server can be implemented by an independent server or a server cluster composed of multiple servers.

[0068] In one embodiment, as Figure 2 shown, a line loss judgment method is provided. Taking the method applied to the Figure 1 computer device as an example, the method includes the following steps:

[0069] S201, determine whether the power supply line is lightly loaded on the verification date according to the daily line loss rate of the power supply line on the verification date and a preset first line loss rate range.

[0070] Optionally, the daily line loss rate can be calculated according to the power supply amount and the sold electricity amount. For example, (power supply amount - sold electricity amount) / power supply amount * 100%; the preset first line loss rate range can be -2% to 5%, or can be 1% to 4%. The embodiments of the present application do not limit this.

[0071] In this embodiment, it is possible to directly compare the daily line loss rate of the power supply line on the verification date with a preset first line loss rate range. If the daily line loss rate of the power supply line on the verification date is within the preset first line loss rate range, it is determined that the power supply line is not lightly loaded on the verification date. If the daily line loss rate of the power supply line on the verification date is outside the preset first line loss rate range, it is determined that the power supply line is lightly loaded on the verification date. For example, the preset first line loss rate range is -2% to 5%, and the daily line loss rate of the power supply line on the verification date is 2%, that is, the daily line loss rate of the power supply line on the verification date is within the first line loss rate range, and it is determined that the power supply line is not lightly loaded on the verification date. Or, if the daily line loss rate of the power supply line on the verification date is within the preset first line loss rate range, it is determined that the power supply line is not lightly loaded on the verification date. If the daily line loss rate of the power supply line on the verification date is outside the preset first line loss rate range, it is further determined whether the power supply line is lightly loaded on the verification date according to whether the daily line loss amount of the power supply line on the verification date is less than a certain preset threshold. For example, the preset first line loss rate range is -2% to 5%, the threshold is 20 KWh, and the daily line loss rate of the power supply line on the verification date is 6%, that is, the daily line loss rate of the power supply line on the verification date is outside the first line loss rate range. It is necessary to further obtain the power supply amount and the sold electricity amount of the power supply line on the verification date, calculate the difference between the power supply amount and the sold electricity amount to obtain the daily line loss amount of the power supply line on the verification date, and compare the daily line loss amount with the preset threshold of 20 KWh. If the daily line loss amount is greater than 20 KWh, it is determined that the power supply line is lightly loaded on the verification date. If the daily line loss amount is not greater than 20 KWh, it is determined that the power supply line is not lightly loaded on the verification date.

[0072] S202. If the power supply line is not lightly loaded on the verification date, obtain the theoretical line loss tables of multiple historical time periods of the power supply line. The theoretical line loss tables include the number of metering devices and the theoretical line losses of the power supply line in each time period.

[0073] In this embodiment, the theoretical line loss tables have been pre-stored in the database. Among them, the theoretical line loss tables include the number of metering devices and the theoretical line losses of the power supply line in each time period. When the power supply line is not lightly loaded on the verification date, the theoretical line loss tables of the power supply line can be directly obtained. For example, on the verification date of December 5, 2021, for power supply line 1, from November 1 to November 30, 2021, the number of metering devices is 8, and the theoretical line loss is 5%. From October 1 to October 30, 2021, the number of metering devices is 6, and the theoretical line loss is 3.2%.

[0074] S203. Compare the difference between the number of metering devices in the current time period of the power supply line and the number of metering devices in each historical time period with a first threshold to obtain a comparison result.

[0075] In this embodiment, optionally, the first threshold may be 2, 3, 5, etc., and the embodiments of the present application do not limit this. For example, the first threshold may be 2. The number of metering devices in the current time period (December 2021) of the power supply line 1 is 4. In historical time period 1, that is, from November 1, 2021 to November 30, 2021, the number of metering devices is 8. In historical time period 2, that is, from October 1, 2021 to October 30, 2021, the number of metering devices is 6. In historical time period 3, that is, from September 1, 2021 to September 30, 2021, the number of metering devices is 3. Comparing with the first threshold, the differences are obtained by subtracting the number of metering devices in the current time period from those in historical time period 1, historical time period 2, and historical time period 3 respectively, and the differences are -4, -2, and 1 respectively. That is, compared with November 1, 2021 - November 30, 2021, the number of metering devices in the current time period has decreased by 4. Compared with October 1, 2021 - October 30, 2021, the number of metering devices in the current time period has decreased by 2. Compared with September 1, 2021 - September 30, 2021, the number of metering devices in the current time period has increased by 1.

[0076] S204. Determine whether the actual line loss in the current time period is normal according to the comparison result and the theoretical line losses and line loss dates of each historical time period.

[0077] In this embodiment, according to the comparison result, the theoretical line loss with the smallest difference in the number of metering devices in the current time period can be found as the threshold, and the actual line loss in the current time period is compared with this threshold. If the actual line loss in the current time period is greater than this threshold, the actual line loss in the current time period is abnormal; if the actual line loss in the current time period is not greater than this threshold, the actual line loss in the current time period is normal. For example, the actual line loss in the current time period is 2%. From November 1, 2021 to November 30, 2021, the theoretical line loss is 5%. From October 1, 2021 to October 30, 2021, the theoretical line loss is 3.2%. From September 1, 2021 to September 30, 2021, the theoretical line loss is 2.5%. Based on the above steps, it can be known that the smallest difference in the number of metering devices between each historical time period and the current time period is 1. The corresponding line loss date is from September 1, 2021 to September 30, 2021, and the theoretical line loss is 2.5%. The actual line loss in the current time period is 2%, which is less than the theoretical line loss of 2.5%, so the actual line loss in the current time period is normal. It is also possible to obtain the theoretical line loss of the time period with the smallest time difference from the current time period as the threshold according to the comparison result, and compare the actual line loss in the current time period with this threshold. If the actual line loss in the current time period is greater than this threshold, the actual line loss in the current time period is abnormal; if the actual line loss in the current time period is not greater than this threshold, the actual line loss in the current time period is normal. For example, still based on the above steps, it can be known that the theoretical line loss of the time period with the smallest time difference from the current time period (i.e., from November 1, 2021 to November 30, 2021) is 5%. The theoretical line loss in the current time period is 2%, which is less than the theoretical line loss of 5%, so the actual line loss in the current time period is normal. Or find the one with the smallest theoretical line loss among all historical time periods as the threshold and compare it with the current time period. Compare the actual line loss in the current time period with this threshold. If the actual line loss in the current time period is greater than this threshold, the actual line loss in the current time period is abnormal; if the actual line loss in the current time period is not greater than this threshold, the actual line loss in the current time period is normal. For example, the one with the smallest theoretical line loss is still from September 1, 2021 to September 30, 2021, and the theoretical line loss is 2.5%. The actual line loss in the current time period is 2%, which is less than the theoretical line loss of 2.5%, so the actual line loss in the current time period is normal.

[0078] In the above line loss judgment method, according to the daily line loss rate on the verification date of the power supply line and the preset first line loss rate range, it is determined whether the power supply line is lightly loaded on the verification date; if the power supply line is not lightly loaded on the verification date, the theoretical line loss tables of multiple historical time periods of the power supply line are obtained; the difference between the number of metering devices in the current time period of the power supply line and the number of metering devices in each historical time period is compared with the first threshold value to obtain a comparison result; according to the comparison result and the theoretical line losses and line loss dates of each historical time period, it is judged whether the actual line loss in the current time period is normal. Before judging the line loss, the method of this application first identifies the light load of the line to avoid misjudgment caused by the light load of the line. Moreover, for the theoretical line losses of the line in each historical time period, they have been pre-stored in the theoretical line loss table, and it is not necessary for the power management department to specifically provide the length, power supply radius, material, etc. of the line for calculation, making the judgment of the line loss more simple and efficient.

[0079] The above Figure 2 The embodiment introduces the method for judging the line loss. Next, the specific process of "S201. According to the daily line loss rate on the verification date of the power supply line and the preset first line loss rate range, determine whether the power supply line is lightly loaded on the verification date" will be mainly introduced, as Figure 3 shown, including the following steps:

[0080] S301. If the daily line loss rate on the verification date of the power supply line is within the first line loss rate range, it is determined that the power supply line is not lightly loaded on the verification date.

[0081] In this embodiment, the first line loss rate range is close to the theoretical line loss of the power supply line. If the daily line loss rate on the verification date of the power supply line is within the first line loss rate range, it proves that there are no other abnormal situations for the power supply line, and the daily line loss rate is the loss of the power supply line itself, so it is determined that the power supply line is not lightly loaded on the verification date. For example, the preset first line loss rate range is -2% to 5%, and the daily line loss rate on the verification date of the power supply line is 2%, that is, the daily line loss rate on the verification date of the power supply line is within the first line loss rate range, and it is determined that the power supply line is not lightly loaded on the verification date.

[0082] S302. If the daily line loss rate on the verification date of the power supply line is outside the first line loss rate range, it is judged whether the absolute value of the daily line loss amount of the power supply line is not greater than the second threshold value; the second threshold value is determined according to the multiplier of the gateway meter.

[0083] Among them, the daily line loss quantity also represents the daily power loss of the power supply line, which is obtained based on the power supply quantity and the power sold. For example, if the power supply quantity is 200 KWh and the power sold is 180 KWh, then the daily line loss quantity is 20 KWh. The second threshold is determined according to the multiplier of the gateway meter. The gateway meter refers to the total metering meter of an area, and this area includes multiple users. The gateway meter records the power metering meters of all users in this area. When determining the second threshold, the multiplier of the gateway meter can be directly used as the second threshold. For example, if the multiplier of the gateway meter is 200, then the second threshold is 200; or the multiplier of the gateway meter can be multiplied by a percentage as the second threshold. For example, if the multiplier of the gateway meter is 200 and the percentage is 2%, then the second threshold is 4.

[0084] In this embodiment, when the daily line loss rate of the power supply line on the verification day is outside the first line loss rate range, it proves that there may be abnormal conditions in the power supply line. It may be caused by light load, resulting in fluctuations in the daily line loss rate of the power supply line on the verification day. It may also be due to a power transfer event in the current power supply line, a too large difference in the number of metering devices, resulting in fluctuations in the daily line loss rate of the power supply line on the verification day. Or there is a process of reporting suspension or reporting start in the process of the metering device of the power supply line, resulting in fluctuations in the daily line loss rate of the power supply line on the verification day. Therefore, it is necessary to further determine whether the power supply line is lightly loaded on the verification day according to whether the absolute value of the daily line loss quantity of the power supply line on the verification day is not greater than the second threshold.

[0085] S303. In the case where the absolute value of the daily line loss quantity is greater than the second threshold, it is determined that the power supply line is not lightly loaded on the verification day.

[0086] In this embodiment, the second threshold is determined according to the multiplier of the gateway meter. For example, according to the multiplier of the gateway meter 400 and the percentage 2%, the determined second threshold is 8. The power supply quantity of the power supply line on the verification day is 200 KWh, and the power sold is 180 KWh, that is, the daily line loss quantity is 20 KWh. Then the absolute value of the daily line loss quantity is greater than the second threshold, and it is determined that the power supply line is not lightly loaded on the verification day.

[0087] S304. In the case where the absolute value of the daily line loss quantity is not greater than the second threshold, obtain the first line loss information of multiple dates based on the verification day, and determine whether the power supply line is lightly loaded on the verification day according to the first line loss information.

[0088] Among them, the first line loss information includes all information of the power supply line. For example, the power supply quantity, power sold, daily line loss quantity, daily line loss rate of the power supply line, as well as the number of metering devices carried by the power supply line, statistical time, process of the metering device, etc.

[0089] In this embodiment, when the absolute value of the daily line loss amount is not greater than the second threshold, the first line loss information for multiple dates is obtained based on the verification date. For example, the verification date is December 10, 2021, the daily line loss amount is 6 KWh, and the daily line loss rate is 2%. Based on the verification date, the first line loss information for a total of 6 days from December 6, 2021 to December 9, 2021, and from December 11, 2021 to December 12, 2021 is obtained. Among them, the daily line loss amount on December 6, 2021 is 4 KWh, and the daily line loss rate is 2.5%; the daily line loss amount on December 7, 2021 is 9 KWh, and the daily line loss rate is 3.2%; the daily line loss amount on December 8, 2021 is 10 KWh, and the daily line loss rate is 2.8%; the daily line loss amount on December 9, 2021 is 6 KWh, and the daily line loss rate is 2.6%; the daily line loss amount on December 11, 2021 is 4 KWh, and the daily line loss rate is 1.4%; the daily line loss amount on December 12, 2021 is 9 KWh, and the daily line loss rate is 3%. It is possible to compare the daily line loss amount on the verification date of the power supply line with the average daily line loss amount for multiple dates. When the daily line loss amount on the verification date is greater than the average daily line loss amount, it is determined that the power supply line is lightly loaded on the verification date. When the daily line loss amount on the verification date is not greater than the average daily line loss amount, it is determined that the power supply line is not lightly loaded on the verification date. For example, the average daily line loss amount corresponding to these 7 days (from December 6, 2021 to December 12, 2021) is 6.86 KWh. Since the average daily line loss amount for multiple days is greater than the daily line loss amount of 6 KWh on the verification date, the power supply line is not lightly loaded on the verification date. It is also possible to compare the daily line loss rate on the verification date of the power supply line with the average daily line loss rate for multiple dates. When the daily line loss rate on the verification date is greater than the average daily line loss rate, it is determined that the power supply line is lightly loaded on the verification date. When the daily line loss amount on the verification date is not greater than the average daily line loss rate, it is determined that the power supply line is not lightly loaded on the verification date. For example, the average daily line loss rate corresponding to these 7 days (from December 6, 2021 to December 12, 2021) is 2.5%. Since the average daily line loss rate of 2.5% for multiple days is greater than the daily line loss rate of 2% on the verification date, the power supply line is not lightly loaded on the verification date. Or, in a way that combines the daily line loss amount and the daily line loss rate, when the daily line loss amount on the verification date is greater than the average daily line loss amount for multiple days, and the daily line loss rate on the verification date is greater than the average daily line loss rate for multiple days, it is determined that the power supply line is lightly loaded on the verification date. When the daily line loss amount on the verification date is not greater than the average daily line loss amount for multiple days, and / or the daily line loss rate on the verification date is not greater than the average daily line loss rate for multiple days, it is determined that the power supply line is not lightly loaded on the verification date. For example, the average daily line loss amount corresponding to these 7 days (from December 6, 2021 to December 12, 2021) is 6.86 KWh, and the daily line loss rate is 2.5%. The daily line loss amount on the verification date is 6 KWh, and the daily line loss rate is 2%. That is, the daily line loss amount on the verification date is less than the average daily line loss rate, and the daily line loss rate on the verification date is less than the average daily line loss rate. Then it is determined that the power supply line is not lightly loaded on the verification date.

[0090] In this embodiment, based on the daily line loss rate of the power supply line on the verification day and the preset first line loss rate range, it is determined whether the power supply line is lightly loaded on the verification day. If it is within the first line loss rate range, it is determined that the power supply line is not lightly loaded on the verification day. If it is outside the first line loss rate range, the absolute value of the daily line loss amount of the power supply line on the verification day is further compared with the second threshold. When the absolute value of the daily line loss amount is greater than the second threshold, the power supply line is not lightly loaded on the verification day. If the absolute value of the daily line loss amount is not greater than the second threshold, further judgment is made. When the daily line loss rate does not meet the first line loss rate range, this method combines the daily line loss amount for identification. Further, the first line loss information within a period of time is obtained based on the verification day. Based on the first line loss information, it is identified whether the line is lightly loaded. This is done step by step, so that the accuracy of identifying whether the power supply line is lightly loaded is higher.

[0091] Based on the above Figure 3 In the embodiment, in "S304, when the absolute value of the daily line loss is not greater than the second threshold, the first line loss information of multiple dates is obtained based on the verification date, and whether the power supply line is lightly loaded on the verification date is determined according to the first line loss information." The line loss is further determined, such as Figure 4 As shown, the following steps are included:

[0092] S401, from the first line loss information, the line loss information corresponding to the date whose absolute value of the daily line loss amount is greater than the second threshold is eliminated to obtain the second line loss information of the remaining dates. If the number of days of the remaining dates is equal to the third threshold, then step S402 is executed; if the number of days of the remaining dates is greater than the third threshold, then step S403 is executed.

[0093] In this embodiment, the first line loss information obtained may include line loss information that does not meet the line loss requirements, for example, line loss information corresponding to the date when the absolute value of the daily line loss is greater than the second threshold, the process of the metering device of the line has a replacement process, or the process of the metering device of the line has a stop or start process, etc. It can be seen from the above steps that when the absolute value of the daily line loss is greater than the second threshold, the power supply line is not lightly loaded on the verification day. Therefore, it is necessary to eliminate the line loss information corresponding to the date when the absolute value of the daily line loss is greater than the second threshold, and obtain the second line loss information of the remaining dates. For example, taking the above steps as an example, the line loss information corresponding to the dates whose absolute value of daily line loss is greater than the second threshold is eliminated. The second threshold is 8. The daily line losses from December 6, 2021 to December 12, 2021 are 4KWh, 9KWh, 10KWh, 6KWh, 6KWh, 4KWh, and 9KWh, respectively. Among them, the daily line loss of 9KWh on December 7, 2021 is greater than the second threshold 8, the daily line loss of 10KWh on December 8, 2021 is greater than the second threshold 8, and the daily line loss of 9KWh on December 12, 2021 is greater than the second threshold 8. The remaining dates are December 6, 2021, December 9, 2021, December 10, 2021, and December 11, 2021, and the second line loss information is the line loss information corresponding to the remaining dates.

[0094] S402, if the number of days of the remaining dates is equal to the third threshold, then the first line loss amount average value of the remaining dates is calculated according to the second line loss information, and the first line loss rate average value of the remaining dates is calculated according to the second line loss information. If the first line loss amount average value is not greater than the fourth threshold, and the first line loss rate average value is within the second line loss rate range, it is determined that the power supply line is lightly loaded on the verification day. If the situation of "the first line loss amount average value is not greater than the fourth threshold, and the first line loss rate average value is within the second line loss rate range" is not satisfied, step S404 is executed.

[0095] In this embodiment, optionally, the fourth threshold value can be 20, 30, or 50, and the embodiment of the present application does not limit this. The second line loss information includes the daily line loss amount and daily line loss rate of the power supply line. Assume that the third threshold value is 2, the fourth threshold value can be 15KWh, and the second line loss rate ranges from 1% to 3%. The remaining dates are December 10, 2021 and December 11, 2021. The daily line loss amount on December 10, 2021 is 6KWh and the daily line loss rate is 3%. The daily line loss amount on December 10, 2021 is 4KWh and the daily line loss rate is 2%. The average value of the first line loss amount is 5KWh, and the average value of the first line loss rate is 2.5%. That is, the average value of the first line loss amount is 5KWh, which is less than 15KWh, and the average value of the first line loss rate is 2.5%, which is in the second line loss rate range of 1% to 3%. It is determined that the power supply line is lightly loaded on the verification day.

[0096] S403. If the number of days in the remaining dates is greater than the third threshold, calculate the average value of the second line loss quantity and the average value of the second line loss rate for the first time period, the second time period, and the third time period according to the second line loss information. If the average value of the second line loss quantity is not greater than the fourth threshold and the average value of the second line loss rate is within the second line loss rate range, determine that the power supply line is lightly loaded on the verification date. The first time period includes the verification date and the first number of days after the verification date. The second time period includes the verification date and the first number of days before the verification date. The third time period includes the verification date, the first number of days after the verification date, and the first number of days before the verification date. If the condition "the average value of the second line loss quantity is not greater than the fourth threshold and the average value of the second line loss rate is within the second line loss rate range" is not met, then execute step S407.

[0097] In this embodiment, the first number can be 1, 2, 3, etc., and the embodiments of the present application do not limit this. If the number of days in the remaining dates is greater than the third threshold, it proves that there are multiple remaining dates that meet the above requirements. From the multiple remaining dates, select the date closest to the verification date. The verification date and the date closest to the verification date can be combined in various forms to form the first time period, the second time period, and the third time period. For example, still taking the above steps as an example, the fourth threshold can be 15 KWh, the second line loss rate range is 1% - 4%, the remaining dates are December 6, 2021, December 9, 2021, December 10, 2021, and December 11, 2021. December 10, 2021 is the verification date. The two days closest to the verification date are selected as December 9, 2021 and December 11, 2021. The daily line loss quantity on December 9, 2021 is 6 KWh, and the daily line loss rate is 3%. The daily line loss quantity on December 10, 2021 is 6 KWh, and the daily line loss rate is 2%. The daily line loss quantity on December 11, 2021 is 4 KWh, and the daily line loss rate is 5%. Taking December 9, 2021 and December 10, 2021 as the first time period, December 10, 2021 and December 11, 2021 as the second time period, and December 9, 2021, December 10, 2021, and December 11, 2021 as the third time period, the average value of the second line loss quantity in the first time period is 6 KWh, the average value of the second line loss rate is 2.5%, the average value of the second line loss quantity in the second time period is 5 KWh, the average value of the second line loss rate is 3.5%, and the average value of the second line loss quantity in the third time period is 5.3 KWh, and the average value of the second line loss rate is 3.3%. It can be found that the average value of the second line loss quantity in the first time period is less than the fourth threshold, and the average value of the second line loss rate is within the second line loss rate range, so it is determined that the power supply line is lightly loaded on the verification date.

[0098] S404. If the average value of the first line loss quantity is greater than the fourth threshold, and / or the average value of the first line loss rate is outside the second line loss rate range, then determine whether the sum of the first power supply quantities for the remaining dates is not greater than the fifth threshold, and whether the sum of the first power sales quantities for the remaining dates is not greater than the sixth threshold. Execute step S405 or S406.

[0099] In this embodiment, optionally, the fifth threshold may be 3, 5, 10, etc., and the sixth threshold may also be 2, 3, 4, etc. The fifth threshold and the sixth threshold may be the same or different. Further, the fifth threshold and the sixth threshold may be determined according to the ratio of the gateway meter. The embodiments of the present application do not limit this. When the average value of the first line loss quantity is greater than the fourth threshold, and / or the average value of the first line loss rate is outside the second line loss rate range, it is necessary to further compare the sum of the first power supply quantities for the remaining dates with the fifth threshold, and compare the sum of the first power sales quantities for the remaining dates with the sixth threshold. The main thing is to determine whether the sum of the first power supply quantities for the remaining dates is not greater than the fifth threshold, and whether the sum of the first power sales quantities for the remaining dates is not greater than the sixth threshold. According to the comparison results, it is judged whether the power supply line is lightly loaded on the verification date.

[0100] In the embodiments of the present application, first, the line loss information that does not meet the requirements is removed from the first line loss information. For the remaining dates after removal, it is divided into two parts. The first part is the case where the number of days of the remaining dates is equal to the third threshold, and the second part is the case where the number of days of the remaining dates is greater than the third threshold. The light load of the power supply line is identified separately from these two cases, ensuring that identification can be carried out even when there is relatively little line loss information that meets the requirements. Moreover, after obtaining the first line loss information for multiple days, the line loss information that may have a light load situation is removed, ensuring the accuracy of light load identification.

[0101] Further, on the basis of the above Figure 4 , when the number of days of the remaining dates is equal to the third threshold, the average value of the first line loss quantity and the average value of the first line loss rate for the remaining dates are calculated respectively. The average value of the first line loss quantity is compared with the fourth threshold, and the average value of the first line loss rate is compared with the second line loss rate range. And when the number of days of the remaining dates is greater than the third threshold, taking the verification date as the base date, three time periods are determined, and the respective average values of the second line loss quantity and the second line loss rate for the three time periods are calculated respectively. The average value of the second line loss quantity is compared with the fourth threshold, and the average value of the second line loss rate is compared with the second line loss rate range. Further, it is also possible to identify whether the power supply line is lightly loaded according to the power supply quantity and the power sales quantity. As Figure 4 shown, it includes the following steps:

[0102] S405. If the sum of the first power supply quantities is not greater than the fifth threshold and the sum of the first power sales quantities is not greater than the sixth threshold, then determine that the power supply line is lightly loaded on the verification date.

[0103] In this embodiment, for example, the fifth threshold is 800 KWh, the sixth threshold is 750 KWh, the remaining dates are December 10, 2021 and December 11, 2021. The power supply on December 10, 2021 is 420 KWh, and the power sold is 400 KWh. The power supply on December 11, 2021 is 350 KWh, and the power sold is 320 KWh. Then the sum of the first power supplies is 770 KWh, and the sum of the first power sales is 720 KWh. That is, the sum of the first power supplies is less than the fifth threshold, and the sum of the first power sales is not greater than the sixth threshold. Then it is determined that the power supply line is lightly loaded on the verification date.

[0104] S406. If the sum of the first power supplies is greater than the fifth threshold, and / or the sum of the first power sales is greater than the sixth threshold, then it is determined that the power supply line is not lightly loaded on the verification date.

[0105] In this embodiment, when at least one of the conditions that the sum of the first power supplies is greater than the fifth threshold and the sum of the first power sales is greater than the sixth threshold is satisfied, then it is determined that the power supply line is not lightly loaded on the verification date. For example, the remaining dates are December 10, 2021 and December 11, 2021. The power supply on December 10, 2021 is 420 KWh, and the power sold is 400 KWh. The power supply on December 11, 2021 is 350 KWh, and the power sold is 320 KWh. Then the sum of the first power supplies is 770 KWh, and the sum of the first power sales is 720 KWh. If the fifth threshold is 760 KWh and the sixth threshold is 750 KWh, then the sum of the first power supplies is greater than the fifth threshold, and it is determined that the power supply line is not lightly loaded on the verification date. If the fifth threshold is 760 KWh and the sixth threshold is 700 KWh, then the sum of the first power supplies is greater than the fifth threshold, and the sum of the first power sales is greater than the sixth threshold, and it is determined that the power supply line is not lightly loaded on the verification date.

[0106] S407. If the average value of the second line losses is greater than the fourth threshold, and / or the average value of the second line loss rate is outside the second line loss rate range, then obtain the sum of the second power supplies and the sum of the second power sales in the first time period, the second time period and the third time period. Execute step S408 or S409.

[0107] In this embodiment, when the average values of the second line loss amounts and the average values of the second line loss rates in each of the above-mentioned first time period, second time period, and third time period cannot simultaneously meet the condition that the average value of the second line loss amount is not greater than the fourth threshold and the average value of the second line loss rate is within the second line loss rate range, the sum of the second power supply amounts and the sum of the second power sales amounts in the first time period, second time period, and third time period are respectively obtained. For example, still taking the above steps as an example, December 9, 2021 and December 10, 2021 are used as the first time period, December 10, 2021 and December 11, 2021 are used as the second time period, and December 9, 2021, December 10, 2021, and December 11, 2021 are used as the third time period. According to the daily power supply amounts and power sales amounts, the sum of the second power supply amounts and the sum of the second power sales amounts in the first time period, second time period, and third time period are calculated.

[0108] S408. If the sum of the second power supply amounts is not greater than the fifth threshold and the sum of the second power sales amounts is not greater than the sixth threshold, it is determined that the power supply line is lightly loaded on the verification date.

[0109] In this embodiment, when the sum of the second power supply amounts in one of the three time periods is not greater than the fifth threshold and the sum of the second power sales amounts is not greater than the sixth threshold, it is determined that the power supply line is lightly loaded on the verification date. For example, the fifth threshold is 800 KWh, the sixth threshold is 750 KWh, the sum of the second power supply amounts in the first time period is 550 KWh, the sum of the second power sales amounts is 520 KWh, the sum of the second power supply amounts in the second time period is 580 KWh, the sum of the second power sales amounts is 540 KWh, the sum of the second power supply amounts in the third time period is 780 KWh, and the sum of the second power sales amounts is 720 KWh, then it is determined that the power supply line is lightly loaded on the verification date.

[0110] S409. If the sum of the second power supply amounts is greater than the fifth threshold and / or the sum of the second power sales amounts is greater than the sixth threshold, it is determined that the power supply line is not lightly loaded on the verification date.

[0111] In this embodiment, when none of the above three time periods can meet the condition that the sum of the second power supply amounts is not greater than the fifth threshold and the sum of the second power sales amounts is not greater than the sixth threshold, it is determined that the power supply line is not lightly loaded on the verification date. For example, the sum of the second power supply amounts in the first time period is greater than the fifth threshold, the sum of the second power sales amounts in the second time period is greater than the sixth threshold, the sum of the second power supply amounts in the third time period is greater than the fifth threshold, and the sum of the second power sales amounts is greater than the sixth threshold, then it is determined that the power supply line is not lightly loaded on the verification date.

[0112] In the embodiments of the present application, when the line loss amount and the line loss rate cannot identify whether the power supply line is lightly loaded, the power supply amount and the sold electricity amount are introduced. By comparing the sum of the power supply amounts and the sum of the sold electricity amounts with the preset thresholds respectively, it is determined whether the power supply line is lightly loaded on the verification date. In the method of the present application, various line loss information is used to identify the power supply line, progressing layer by layer, avoiding the error caused by a single line loss information, making the method for identifying the lightly loaded power supply line more accurate. Moreover, the values of the power supply amount and the sold electricity amount can be directly obtained according to the metering device, and the method is simple, improving the efficiency of identifying the lightly loaded power supply line.

[0113] The above Figure 4 The embodiment introduced the specific process of determining whether the power supply line is lightly loaded on the verification date according to the first line loss information. If the power supply line is not lightly loaded, the theoretical line loss table of the power supply line is obtained, and the line loss is judged according to the theoretical line loss table and the line loss information related to the current time period of the power supply line. Before obtaining the theoretical line loss table, it is also necessary to determine the theoretical line loss of the power supply line. As Figure 5 shown, determining the theoretical line loss of the power supply line includes the following steps:

[0114] S501, according to the line information of the power supply line, determine whether there is a power supply transfer event in the preset time period.

[0115] Among them, the line information may include the corresponding relationships between the line name, line identifier, date, etc. The line name can be Power Supply Line 1, Power Supply Line 2, etc., or Huantian Line, Huanchai Line, etc. Its function is only to distinguish between each line; the line identifier can be power supply transfer, non-power supply transfer, lightly loaded, non-lightly loaded, etc. For example, the line information includes Power Supply Line 1, November 20, 2021, and the line identifier is power supply transfer; the line information includes Power Supply Line 1, November 10, 2021, and the line identifier is non-power supply transfer.

[0116] In this embodiment, according to the line information of the power supply line, determine whether there is a power supply transfer event in the preset time period. If the power supply line has a power supply transfer identifier, it is considered that the power supply line has a power supply transfer event. For example, the preset time period is from November 1, 2021 to November 30, 2021. For Power Supply Line 1, from November 1, 2021 to November 30, 2021, the line identifier is non-power supply transfer; for Power Supply Line 2, on November 10, 2021, the line identifier is power supply transfer, and on November 17, 2021, the line identifier is power supply transfer; for Power Supply Line 3, on November 8, 2021, the line identifier is power supply transfer, on November 15, 2021, the line identifier is power supply transfer, and on November 25, 2021, the line identifier is power supply transfer. Then there is no power supply transfer event for Power Supply Line 1 within the preset time period, and there are power supply transfer events for Power Supply Line 2 and Power Supply Line 3 within the preset time period.

[0117] S502. If there is a sub - power - supply event in the power - supply line, then, taking the date of the sub - power - supply event as a segmentation point, determine at least two non - sub - power - supply time periods from a preset time period; the non - sub - power - supply time periods include dates without sub - power - supply events.

[0118] In this embodiment, if there is a sub - power - supply event in the power - supply line, it indicates that there is at least one day with a sub - power - supply identifier in the power - supply line. Then, taking the date of the sub - power - supply event as a segmentation point, divide the preset time period into multiple non - sub - power - supply time periods. It should be noted that the determined non - sub - power - supply time periods include dates without sub - power - supply events. Continuing with the above step S201 as an example, there are sub - power - supply events in power - supply line 2 and power - supply line 3 within the preset time period. For power - supply line 2, the line identifiers are sub - power - supply on November 10, 2021 and November 17, 2021. Then the three divided non - sub - power - supply time periods are respectively from November 1, 2021 to November 9, 2021, from November 11, 2021 to November 16, 2021, and from November 18, 2021 to November 21, 2021. For power - supply line 3, there are 3 sub - power - supply identifiers, and thus 4 non - sub - power - supply time periods can be correspondingly divided.

[0119] S503. According to the line - loss information of the power - supply line in each non - sub - power - supply time period, obtain the theoretical line loss of the power - supply line.

[0120] In this embodiment, the theoretical line loss of the power - supply line can be directly obtained according to the line - loss information of the power - supply line in each non - sub - power - supply time period. For example, for power - supply line 2, in the first non - sub - power - supply time period from November 1, 2021 to November 9, 2021, obtain all the line - loss information of power - supply line 2 in this time period, and obtain the theoretical line loss of power - supply line 2 according to the obtained line - loss information; or, according to the line - loss information of the power - supply line in each non - sub - power - supply time period, eliminate the line - loss information that does not meet the requirements and significantly affects the calculation results, and use the remaining line - loss information to obtain the theoretical line loss of the power - supply line. For example, for power - supply line 2, in the first non - sub - power - supply time period from November 1, 2021 to November 9, 2021, obtain all the line - loss information of power - supply line 2 in this time period. If some of the line - loss information of power - supply line 2 on November 3, 2021 cannot be obtained normally, then eliminate the line - loss information on November 3, 2021, and use the line - loss information of the remaining 8 days for calculation to obtain the theoretical line loss of power - supply line 2.

[0121] The above Figure 5 embodiment introduced the method for determining the theoretical line loss. Next, the specific process of determining whether there is a sub - power - supply event in the power - supply line will be mainly introduced. As Figure 6 shown, it includes the following steps:

[0122] S601. Query whether there is a sub - power supply identifier in the line information. If so, that is, there is a sub - power supply identifier in the line information, execute step S302. If not, that is, there is no sub - power supply identifier in the line information, execute step S303.

[0123] In this embodiment, the line information has been pre - stored in the database, and the line information of all power supply lines in the power supply system can be queried. For example, power supply system A includes multiple power supply lines. The computer device can first screen the line information according to the "preset time", extract the line information from November 1, 2021 to November 30, 2021, and then extract the power supply lines with sub - power supply identifiers from all power supply lines according to the "sub - power supply identifier"; it can also query the line information of a certain power supply line. For example, for power supply line 1, query whether there is a sub - power supply identifier on November 15, 2021.

[0124] S602. There is a sub - power supply event on the power supply line during the preset time period.

[0125] In this embodiment, when there is a sub - power supply identifier on the power supply line during the preset time period, it is considered that there is a sub - power supply event on the power supply line during the preset time period. For example, the preset time period is from November 1, 2021 to November 30, 2021. On November 8, 2021, the line identifier of power supply line 1 is sub - power supply, then it is considered that there is a sub - power supply event on power supply line 1 during the preset time period.

[0126] S603. There is no sub - power supply event on the power supply line during the preset time period.

[0127] In this embodiment, when there is no sub - power supply identifier on the power supply line during the preset time period, it is considered that there is no sub - power supply event on the power supply line during the preset time period. For example, if the preset time period is from November 1, 2021 to November 30, 2021, and the line identifier of power supply line 1 is non - sub - power supply, then it is considered that there is no sub - power supply event on power supply line 1 during the preset time period. If the preset time period is from November 15, 2021 to November 30, 2021, and on November 8, 2021, the line identifier of power supply line 2 is sub - power supply, then it is considered that there is a sub - power supply event on power supply line 2 during the preset time period.
