Description

Technical Field

[0001] The present application relates to the field of electric power operation and maintenance technology, and in particular to a method, device, computer equipment, storage medium and computer program product for identifying light loads in a substation based on statistical line losses. Background Art

[0002] Line loss management in substations is a key daily task for power companies. The criteria for determining normal and abnormal line loss in substations is key. It is not only a standard for evaluating whether the power company's substation line loss management is in place, but also determines whether the power company needs to invest a lot of manpower and material resources for verification and analysis. In daily management, when the substation load is low, the power supply radius of the low-voltage substation line is too long, and the line loss accounts for a large proportion, the substation line loss rate often exceeds 5% or even exceeds 20%. These substations are often judged as abnormal and included in daily line loss verification, which wastes manpower and increases the management cost of power companies. Therefore, accurately identifying lightly loaded substations is of great significance to the rational allocation of resources by power companies.

[0003] At present, the method of identifying light load in power substations in the power industry has gradually transitioned from the initial unified method of judging all substations within a certain range of values ​​(usually the absolute value of daily line loss below 50 degrees) as light loads to individualization, that is, it is no longer a unified range of values, but identification is based on the situation of the substation itself. There are two specific methods. One is the voltage drop method, that is, when the load of the substation is below 30%, the voltage drop between the head end of the substation (the low-voltage outlet side) and the end (the incoming line end of the meter box) of the individual branches of the substation is used as the basis for calculating the theoretical line loss, and the obtained value is used as the basis for identifying whether this substation is lightly loaded; the other is the benchmark method, that is, the power supply radius is divided into long, medium and short, and the power supply load is divided into three load conditions: heavy, medium and light, and then the two are combined into 9 types, and then the common value of each type in the statistical line loss is used as the benchmark value of the line loss of this type of substation. That is, light load will be combined into three types: light load long distance, light load medium distance, and light load short distance, with benchmark values ​​of 3.5%, 3%, and 2.5% respectively. The line loss in the substation area within the positive and negative deviation of 0.5% of the corresponding benchmark value is considered as light load.

[0004] However, the existing voltage drop method or benchmark method only identifies light load in the substation from the perspective of line loss or line loss rate, which has the technical problem of high probability of missed judgment and misjudgment. Summary of the invention

[0047] 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.

[0048] At present, the technology closest to this application is the benchmark method, which is a method that divides the power supply radius into long, medium and short, and the power supply load into three load conditions: heavy, medium and light. The two are then combined into 9 types, and the common value of each type in the statistical line loss is used as the benchmark value of the line loss of this type of substation. That is, light load will be combined into three types: light load long distance, light load medium distance, and light load short distance, and their benchmark values ​​are 3.5%, 3%, and 2.5% respectively. The positive and negative deviations of the substation line loss in the corresponding benchmark value are all considered light loads within the range of 0.5%.

[0049] The identification method of light load in the power industry, whether it is the unified range value, voltage drop method or benchmark method, is a rough judgment, which is judged only from a single method. For example, the "unified range method" only starts from the perspective of line loss. For example, if the daily line loss is 52 degrees and the daily line loss rate is 9%, the daily line loss in the power station exceeds 50 degrees, and it is judged as light load. Because its daily line loss rate is as high as 9%, the power station is mistakenly judged as abnormal. In fact, it may be due to the fact that the line is too long and the material of the line is poor, resulting in a high proportion of line loss, rather than abnormal management in the power station. The voltage drop method and the benchmark method only start from the perspective of the daily line loss rate, which is not a combination of quantity and rate. Therefore, even if the daily line loss is only 30 degrees, it may be judged as abnormal, rather than light load, because the daily line loss rate is as high as 17%. On the one hand, it is impossible to scientifically evaluate the line loss management level of a power company in the power station area, and on the other hand, due to misjudgment, it brings waste of manpower and material resources to the grassroots power supply bureau.

[0050] Compared with the prior art, this application provides a light load judgment method based on statistical line loss, combining line loss amount and line loss rate. This judgment method is more accurate, can provide more reliable data support for the economic operation of power companies, and improve the operation and management capabilities of low-voltage distribution network lines and line loss management level of power companies.

[0051] The method for identifying light load in a substation based on statistical line loss provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 through a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers.

[0052] The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0053] In one embodiment, Figure 2 As shown in the figure, a method for identifying light load in a substation based on statistical line loss is provided. Figure 1 The server in the example is used to illustrate the following steps:

[0054] Step 202, obtaining the line loss information of the target area within a preset time range; the line loss information includes the line loss rate and the line loss amount.

[0055] Specifically, line loss, referred to as line loss, is the energy loss caused by the transmission of electric energy through the transmission line; in the power system, the substation refers to the power supply range or area of ​​(a) transformer. The target substation is the substation to be identified as light-loaded, and the line loss information of the target substation within a preset time range is obtained, where the line loss information includes the line loss rate and line loss amount, and can also include the power supply and power sales of the target substation.

[0056] Step 204 , checking whether the target area has been detected as light-load qualified. If it has been detected as light-load qualified, the light-load identification of the target area is terminated.

[0057] Specifically, check whether the target area has been detected as qualified for light load. If it has been detected as qualified for light load, end the light load identification of the target area; if it has not been detected as qualified for light load or has not been detected, perform subsequent light load identification on the target area to avoid repeated detection.

[0058] Step 206: If the target area is not detected as light-load qualified, determine whether the target area is light-load qualified based on the line loss information.

[0059] Specifically, if the target area is not detected as light load qualified, including the target area being detected as light load unqualified or the target area not being light load identified, the target area is light load identified based on the line loss rate and line loss amount in the line loss information to determine whether the target area is light load qualified. Figure 3 FIG. 1 is a flow chart of a step of identifying a light load in a target area in an embodiment. The specific identification method is as follows: Figure 3 As shown:

[0060] Step 10: First enter the "Daily Line Loss Judgment of Area" module to calculate:

[0061] Step 20: Check whether the Japanese and Taiwanese areas are marked as qualified. If yes, the process ends. If no, proceed to step 30;

[0062] Step 30: Whether the absolute value of the line loss in the substation area is less than or equal to 50 degrees, if yes, proceed to step 40, otherwise proceed to step 50;

[0063] Step 40: Whether the meter count of the area is 0 and the absolute value of the line loss is greater than 30, if yes, the area is marked as "unqualified", otherwise, the area is marked as "light load qualified";

[0064] Step 50: If the line loss rate of the transformer area is greater than -2% and less than or equal to 2.5%, the transformer area is marked as "light load qualified", otherwise, proceed to step 60;

[0065] Step 60: Is the absolute value of the line loss in the substation area less than or equal to 100? If yes, proceed to step 70; if no, the substation area is marked as "unqualified";

[0066] Step 70: Whether the absolute value of the line loss rate is less than or equal to 3, if yes, the substation is marked as "light load qualified", otherwise, the substation is marked as "unqualified".

[0067] In the above-mentioned substation light load identification method based on statistical line loss, the line loss information of the target substation within a preset time range is obtained; the line loss information includes the line loss rate and the line loss amount, and it is checked whether the target substation has been detected as qualified for light load. If it has been detected as qualified for light load, the light load identification of the target substation is ended. If the target substation has not been detected as qualified for light load, it is judged whether the light load of the target substation is qualified based on the line loss information. It is a judgment method that combines quantity and rate. There are both a single light load identification and judgment method from the perspective of line loss amount, and a light load identification and judgment method from the perspective of a single line loss rate. There is also a light load judgment method that combines line loss amount and line loss rate, which can improve the accuracy of light load identification in substations and reduce the probability of missed judgment and misjudgment.

[0068] In one embodiment, judging whether the light load of the target area is qualified based on the line loss information includes:

[0069] Obtaining the line loss of the target area, and determining whether the absolute value of the line loss of the target area is less than or equal to a preset first line loss threshold;

[0070] If the absolute value of the line loss amount of the target substation is less than or equal to the preset first line loss amount threshold, determine whether the meter count of the target substation is zero, and whether the absolute value of the line loss amount of the target substation is greater than the preset second line loss amount threshold;

[0071] If the meter count of the target area is zero, and the absolute value of the line loss of the target area is greater than a preset second line loss threshold, the light load of the target area is unqualified.

[0072] Specifically, the line loss amount of the target substation is obtained, and it is determined whether the absolute value of the line loss amount of the target substation is less than or equal to the preset first line loss amount threshold value according to the line loss amount. If the absolute value of the line loss amount of the target substation is less than or equal to the preset first line loss amount threshold value, it is determined whether the meter count of the target substation is zero, and whether the absolute value of the line loss amount of the target substation is greater than the preset second line loss amount threshold value. If the meter count of the target substation is zero, and the absolute value of the line loss amount of the target substation is greater than the preset second line loss amount threshold value, the light load of the target substation is unqualified. For example, when the first line loss amount threshold value is 50 degrees and the second line loss amount threshold value is 30, if the absolute value of the line loss amount of the target substation is less than or equal to 50 degrees, the meter count of the target substation is zero, and the absolute value of the line loss amount of the target substation is greater than 30 degrees, the light load of the target substation is unqualified.

[0073] In this embodiment, the light load of the target substation is qualified or not determined by using the preset first line loss threshold and the second line loss threshold. When the absolute value of the line loss of the target substation is less than or equal to the preset first line loss threshold, the meter count of the target substation is determined to be zero, and when the absolute value of the line loss of the target substation is greater than the preset second line loss threshold, the light load of the target substation is marked as unqualified, thereby realizing the judgment of the light load of the target substation based on the line loss, and improving the accuracy of identifying the light load of the target substation.

[0074] In one embodiment, judging whether the light load of the target area is qualified based on the line loss information further includes:

[0075] If the absolute value of the line loss amount of the target substation is greater than a preset first line loss amount threshold, whether the light load of the target substation is qualified is determined based on the line loss rate of the target substation.

[0076] Specifically, if the absolute value of the line loss of the target substation is greater than the preset first line loss threshold, whether the light load of the target substation is qualified is judged based on the line loss rate of the target substation; for example, when the first line loss threshold is 50 degrees, if the absolute value of the line loss of the target substation is greater than 50 degrees, whether the light load of the target substation is qualified is judged based on the line loss rate of the target substation.

[0077] In this embodiment, when the absolute value of the line loss amount of the target substation is greater than the preset first line loss threshold, a judgment is made as to whether the light load of the target substation is qualified based on the line loss rate of the target substation, thereby realizing the identification of the light load of the target substation based on the line loss amount and the line loss rate, and improving the accuracy of the identification of the light load of the target substation.

[0078] In one embodiment, judging whether the light load of the target area is qualified based on the line loss information further includes:

[0079] If the absolute value of the line loss of the target substation is less than or equal to the preset first line loss threshold, and the meter count of the target substation is not zero, and / or the absolute value of the line loss of the target substation is less than the preset second line loss threshold, the light load of the target substation is qualified.

[0080] Specifically, if the absolute value of the line loss of the target area is less than or equal to the preset first line loss threshold, and the meter count of the target area is not zero, and / or the absolute value of the line loss of the target area is less than the preset second line loss threshold, then the light load of the target area is qualified; for example, when the first line loss threshold is 50 degrees and the second line loss threshold is 30, if the absolute value of the line loss of the target area is less than or equal to 50, and the meter count of the target area is not zero, and / or the absolute value of the line loss of the target area is less than 30, then the light load of the target area is qualified.

[0081] In this embodiment, the light load of the target substation is determined based on the preset first line loss threshold and the preset second line loss threshold, which can improve the light load identification accuracy of the substation and reduce the probability of missed judgment and misjudgment.

[0082] In one embodiment, judging whether the light load of the target area is qualified based on the line loss rate of the target area includes:

[0083] Determine whether the line loss rate of the target station area is greater than a preset first line loss rate threshold and less than or equal to a preset second line loss rate threshold;

[0084] If the line loss rate of the target area is greater than a preset first line loss rate threshold and less than or equal to a preset second line loss rate threshold, the light load of the target area is qualified.

[0085] Specifically, when the light load of the target substation is determined based on the line loss rate of the target substation, it is determined whether the line loss rate of the target substation is greater than the preset first line loss rate threshold and less than or equal to the preset second line loss rate threshold. If the line loss rate of the target substation is greater than the preset first line loss rate threshold and less than or equal to the preset second line loss rate threshold, the light load of the target substation is qualified; for example, when the first line loss rate is -2% and the second line loss rate is 2.5%, if the line loss rate of the target substation is greater than -2% and less than or equal to 2.5%, the light load of the target substation is qualified.

[0086] In this embodiment, it is determined whether the line loss rate of the target substation is greater than the preset first line loss rate threshold and less than or equal to the preset second line loss rate threshold. When the line loss rate of the target substation is greater than the preset first line loss rate threshold and less than or equal to the preset second line loss rate threshold, the light load of the target substation is qualified. The light load of the target substation is determined by the preset first line loss rate threshold and the preset second line loss rate threshold, which can improve the accuracy of light load identification in the substation and reduce the probability of missed judgment and misjudgment.

[0087] In one embodiment, judging whether the light load of the target area is qualified based on the line loss rate of the target area further includes:

[0088] If the line loss rate of the target station area is less than or equal to a preset first line loss rate threshold or greater than a preset second line loss rate threshold, determining whether the absolute value of the line loss amount of the target station area is less than or equal to a preset third line loss amount threshold;

[0089] If the absolute value of the line loss amount of the target area is less than or equal to the preset third line loss amount threshold, determine whether the absolute value of the line loss rate of the target area is less than or equal to the preset third line loss rate threshold, if so, the light load of the target area is qualified; if not, the light load of the target area is unqualified;

[0090] If the absolute value of the line loss of the target substation is greater than the preset third line loss threshold, the light load of the target substation is unqualified.

[0091] Specifically, if the line loss rate of the target substation is less than or equal to the preset first line loss rate threshold or greater than the preset second line loss rate threshold, determine whether the absolute value of the line loss amount of the target substation is less than or equal to the preset third line loss amount threshold. If the absolute value of the line loss amount of the target substation is less than or equal to the preset third line loss amount threshold, determine whether the absolute value of the line loss rate of the target substation is less than or equal to the preset third line loss rate threshold. If so, the light load of the target substation is qualified; if not, the light load of the target substation is unqualified. If the absolute value of the line loss amount of the target substation is greater than the preset third line loss amount threshold, the light load of the target substation is unqualified. For example, When the preset first line loss rate is -2%, the second line loss rate is 2.5%, the third line loss rate threshold is 3%, and the third line loss amount threshold is 100, when the line loss rate of the target area is less than or equal to -2% or greater than 2.5%, it is determined whether the absolute value of the line loss amount of the target area is less than or equal to 100. If the absolute value of the line loss amount of the target area is less than or equal to 100, it is determined whether the absolute value of the line loss rate of the target area is less than or equal to 3%. If so, the light load of the target area is qualified; if not, the light load of the target area is unqualified. If the absolute value of the line loss amount of the target area is greater than 100, the light load of the target area is unqualified.

[0092] In this embodiment, the light load of the target substation is judged based on the preset first line loss rate threshold, second line loss rate threshold, third line loss amount threshold and third line loss rate threshold. There are both a light load identification and judgment method based on the line loss amount, and a light load identification and judgment method based on the line loss rate, as well as a light load judgment method combining the line loss amount and the line loss rate. This can improve the accuracy of light load identification in the substation and reduce the chances of missed judgment and misjudgment.

[0093] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0094] Based on the same inventive concept, the embodiment of the present application also provides a light load identification device for substations based on statistical line loss for implementing the light load identification method for substations based on statistical line loss involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more embodiments of the light load identification device for substations based on statistical line loss provided below can be referred to the limitations of the light load identification method for substations based on statistical line loss above, and will not be repeated here.

[0095] In one embodiment, Figure 4 As shown, a light load identification device for a substation based on statistical line loss is provided, comprising: an acquisition module 401, a verification module 402 and a judgment module 403, wherein:

[0096] The acquisition module 401 is used to acquire the line loss information of the target area within a preset time range; the line loss information includes the line loss rate and the line loss amount.

[0097] The checking module 402 is used to check whether the target area has been detected as light-load qualified. If it has been detected as light-load qualified, the light-load identification of the target area is terminated.

[0098] The judgment module 403 is used to judge whether the light load of the target area is qualified based on the line loss information when the target area is not detected as light load qualified.
