[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein are for the purpose of describing embodiments of the present invention only and are not intended to limit the present invention.

[0061] The embodiment of the present application provides a method for testing edge computing in a power grid substation. The line loss in a low-voltage substation is an important technical indicator in the power system. Accurately and efficiently calculating the line loss through the edge computing function of the upper device has become an indispensable function in the power system. However, in actual applications, the edge computing defects of the upper device are difficult to know, which affects the accuracy of the line loss calculation results. In order to ensure the accuracy of the line loss calculation results, in the prior art, a method of manually collecting power data using a handheld mobile power terminal is used, and the power data is used to verify the line loss calculation results of the upper device, so as to achieve the purpose of testing edge computing defects. However, manual on-site data collection not only increases labor costs, but also makes it difficult to ensure the quality of the collected data, resulting in increased testing costs and reduced test accuracy.

[0062] In order to overcome the above defects, this application provides a power grid area edge computing test method, such as Figure 1 As shown, including:

[0063] 101. Determine the substation line loss parameters of the substation simulation model.

[0064] In one embodiment, the substation simulation model is used to simulate the meter box branches and electric meters of the actual substation, and various parameters in the substation can be configured, such as branch line loss, fixed loss and total power consumption. Among them, the actual substation simulated is the substation that needs to be tested for edge computing. The substation includes an upper device, and the upper device is configured with an edge computing algorithm. For ease of understanding, in one application scenario, the upper device is the main station of the power grid, and the main station has identified the line topology of the substation to which it belongs; in another application scenario, the upper device is a terminal device with computing capabilities. This embodiment does not specifically limit this.

[0065] In one embodiment, the substation line loss parameters refer to parameters related to line loss in the substation simulation model, such as the branch line loss of each meter box branch in the substation simulation model, the substation fixed loss value and the total power consumption in the substation simulation model. This embodiment does not make any specific limitations on this. It should be noted that the substation line loss parameters can be determined by receiving them through a preset interface, and then determining the substation line loss parameters; or by retrieving them from a preset storage path, and then determining the substation line loss parameters; or they can be calculated by the current execution entity according to the configuration of the substation simulation model. This embodiment does not make any specific limitations on this.

[0066] 102. Calculate the substation line loss parameters according to a preset substation power model to obtain substation power data.

[0067] Among them, the substation power model is an algorithm formula. After the substation line loss parameters are brought into the substation power model, the unknown parameters in the substation power model can be calculated, that is, the substation power data can be obtained by calculation.

[0068] 103. Output the substation power data and the test data in the substation line loss parameters to the upper device according to a preset data output type condition, and receive the upper line loss data returned by the upper device according to the test data.

[0069] The substation line loss parameters are known parameters, and the substation power data is a calculated parameter. Both are known quantities. Test data matching the data output type conditions in the substation line loss parameters and substation power data is transmitted to the host device. The host device uses the edge computing required for the test to calculate the test data and obtain the host line loss data.

[0070] It should be noted that the upper-level line loss data has corresponding known quantities in the substation line loss parameters and / or substation power data, which facilitates comparison to verify whether there are defects in the edge computing in the upper-level equipment and achieve the test purpose.

[0071] 104. Use the substation line loss parameters to verify the upper line loss data to obtain edge computing test results.

[0072] The substation line loss parameters include parameters corresponding to the upper-level line loss data. Since the substation line loss parameters are known quantities, they can be used to verify the upper-level line loss data to determine whether the upper-level line loss data is accurate, thereby obtaining the edge computing test results. For ease of understanding, in one application scenario, the verification process involves comparing the substation line loss parameters with the upper-level line loss data to determine whether they are identical. If they are identical, the edge computing test result is generated as correct; if they are different, the edge computing test result is generated as incorrect.

[0073] In another application scenario, the verification process is to perform relational operations on the substation line loss parameters and the upper-level line loss data, and generate corresponding edge computing test results based on the operation results.

[0074] By setting up a substation simulation model, when testing for edge computing defects in upper-level equipment in a power grid substation, the substation simulation model can be configured based on the substation to be tested. The substation line loss parameters for the substation simulation model are then determined and calculated using the substation power model to obtain substation power data. The upper-level line loss data, calculated by the upper-level equipment based on the substation power data and the substation line loss parameters, is then received. By comparing the upper-level line loss data with the substation power data, the edge computing test results are obtained. The entire testing process eliminates the need for on-site data collection, helping to reduce testing costs. Furthermore, the substation simulation model can simulate a variety of substations to be tested, increasing testing flexibility. Using the substation power model for calculations helps improve test accuracy.

[0075] In another embodiment of the present application, Figure 2 As shown, the step of calculating the line loss parameters of the substation area according to the preset substation area power model to obtain the substation area power data includes:

[0076] 201. Determine the total number of electric meters in the substation according to the line loss parameters of the substation.

[0077] In one embodiment, the area line loss parameter includes the branch line loss for each branch. The total number of electricity meters in the area can be determined by summing the branch line losses. In another embodiment, the area line loss parameter includes the total number of electricity meters in the area. The area line loss parameter can be retrieved from the name or number of the total number of electricity meters in the area. This is not specifically limited in this embodiment.

[0078] 202. Construct a data equation group including the line loss parameters of the substation according to the substation power model.

[0079] Each substation contains at least two branches. The data equation group can be obtained by bringing the branch line losses of each branch and the total meter electric energy of the substation into the substation power model.

[0080] Specifically, in one embodiment, the number of equations in the data equation group is the same as the total number of electric meters in the substation.

[0081] 203. Calculate the data equation group using an elimination and back-stripping algorithm to obtain the substation power data.

[0082] By calculating the data equations using an elimination and back-carrying algorithm, the substation power data can be obtained. Specifically, in one embodiment, the substation power data includes the sub-metered energy corresponding to each branch. That is, in the data equations, the sub-metered energy of each branch is an unknown quantity, while all other quantities are known. The sub-metered energy is obtained through calculation.

[0083] The elimination and back-stripping algorithm is used to calculate the data equation group to obtain the substation power data, which helps to improve the test accuracy.

[0084] In another embodiment of the present application, the step of constructing a data equation group containing the substation line loss parameters according to the substation power model includes:

[0085] The total meter electric energy of the substation, the branch line loss of each branch and the fixed line loss of the substation in the substation line loss parameters are brought into the substation power model to obtain the data equation group for calculating the sub-meter electric energy.

[0086] Specifically, in one embodiment, the total meter electric energy of the substation = the sum of all sub-meter electric energy + the corresponding branch loss + the fixed line loss of the substation, and the substation power model is obtained:

[0087]

[0088] Among them, y () is the total metered electrical energy of the area in metering period i, in kWh; is the electric energy of sub-meter j in metering period i; p is the total number of electric meters in the substation; ε j is the branch line loss of sub-meter j branch; ε0 is the fixed line loss of the substation.

[0089] The power model of the substation area can be further obtained from formula (1):

[0090]

[0091] By incorporating the total metered energy, branch line losses, and fixed line losses into the power model, a set of equations is generated. This is a simple and fast method that helps reduce resource usage and improve computational efficiency.

[0092] In another embodiment of the present application, Figure 3 As shown, the step of outputting the substation power data and the test data in the substation line loss parameters to the upper device according to the preset data output type condition, and receiving the upper line loss data returned by the upper device according to the test data includes:

[0093] 401. According to the data output type condition, retrieve the substation power data and the substation line loss parameters including the substation total meter electric energy, the substation fixed line loss and the sub-meter electric energy to determine the test data.

[0094] In one embodiment, the sub-metered energy is retrieved from the substation power data, and the total metered energy and fixed line loss are retrieved from the substation line loss parameters. That is, in this embodiment, the test data includes the total metered energy, fixed line loss, and sub-metered energy.

[0095] 402 : Encapsulate the test data according to the power grid protocol between the host device and the host device, and transmit the encapsulated test data to the host device.

[0096] The power grid protocol is pre-configured between the current execution subject and the upper device. The power grid protocol is used to support data communication capabilities between the current execution subject and the upper device. In this embodiment, the power grid protocol is not specifically limited.

[0097] 403. Receive the upper-level line loss data fed back by the upper-level device based on the power grid protocol.

[0098] In one embodiment, after the test data is transmitted to the host device, the host device uses a preset edge computing algorithm to calculate the test data and obtain upper-level line loss data. In one application scenario, the upper-level line loss data includes the branch line loss of each branch. In another application scenario, the upper-level line loss data includes the branch line loss of each branch and the total line loss of the substation.

[0099] Data interaction through preset power grid protocols helps improve data transmission efficiency and data integrity.

[0100] In another embodiment of the present application, the step of verifying the upper line loss data using the substation line loss parameter to obtain the edge computing test result includes:

[0101] The branch line loss in the substation line loss parameter is compared with the branch calculated line loss of the corresponding branch in the upper line loss data. When the branch line loss of all branches matches the corresponding branch calculated line loss, the edge computing test result is generated to indicate that the edge computing is correct.

[0102] Specifically, in one embodiment, when the branch line loss in the substation line loss parameter is the same as the branch calculated line loss of the corresponding branch in the upper line loss data, it is determined to be a match; and when all branch line losses are a match, the edge computing test result is generated as the edge computing is correct. If the branch line loss corresponding to any branch is not connected, the edge computing result is generated as the edge computing error. Among them, when the edge computing test result is that the edge computing is correct, it means that the edge computing of the upper device is currently flawless and does not need to be modified or improved. When the edge computing test result is an edge computing error, it means that the edge computing of the upper device has defects and needs to be modified or improved.

[0103] It should be noted that when configuring a substation simulation model, faulty lines or abnormal data can be configured to test the edge computing of the upper-level device. For example, the substation simulation model may include events such as stop-and-go, fly-away, voltage failure, and metering inaccuracy. This embodiment does not specifically limit this.

[0104] By comparing the branch routes of each branch, the corresponding edge computing test results are generated. This method is simple, error-prone, and resource-saving.

[0105] In another embodiment of the present application, the step of determining the area line loss parameters of the area simulation model includes:

[0106] 601. Obtain the total meter electric energy, total bus loss and fixed line loss of the substation area of ​​the substation area simulation model.

[0107] In one embodiment, the total meter energy, bus loss, and fixed line loss of the substation area are received and obtained via a preset interface; in another embodiment, the total meter energy, bus loss, and fixed line loss of the substation area are retrieved from a storage space according to a preset instruction or a received instruction. This embodiment does not specifically limit this.

[0108] 602. Process the total line loss of the substation area using a preset constraint formula to calculate the branch line loss of each branch.

[0109] In one embodiment, the constraint formula is:

[0110]

[0111] Among them, ε y It is the bus loss in the substation area.

[0112] 603. Determine the total meter electric energy of the substation, the total bus loss of the substation, the fixed line loss of the substation and the branch line loss as the substation line loss parameters.

[0113] The branch line loss of each branch is calculated through the constraint formula, which saves the branch line loss configuration time and reduces the time cost of testing.

[0114] In another embodiment of the present application, the upper-level line loss data includes branch calculated line losses of each branch.

[0115] By setting up a substation simulation model, when testing for edge computing defects in upper-level equipment in a power grid substation, the substation simulation model can be configured based on the substation to be tested. The substation line loss parameters for the substation simulation model are then determined and calculated using the substation power model to obtain substation power data. The upper-level line loss data, calculated by the upper-level equipment based on the substation power data and the substation line loss parameters, is then received. By comparing the upper-level line loss data with the substation power data, the edge computing test results are obtained. The entire testing process eliminates the need for on-site data collection, helping to reduce testing costs. Furthermore, the substation simulation model can simulate a variety of substations to be tested, increasing testing flexibility. Using the substation power model for calculations helps improve test accuracy.
