Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of transformer area simulation, and in particular to a tool troubleshooting method under a virtual transformer area. BACKGROUND
[0002] Currently, most power transformer area simulation devices are presented in the form of cabinet equipment. These devices usually provide equipment and fault display in a fixed and closed hardware form, mainly for basic fault simulation and equipment state display. However, this cabinet simulation method has significant limitations. First, the cabinet equipment cannot truly restore the complex environment and actual operating state of the power transformer area site, and it is difficult to reflect the dynamic changes of the transformer area equipment and power lines. The actual layout of the transformer area is usually complex, involving multiple power equipment (such as distribution transformers, switch equipment, electricity meters, etc.) and complex line topology structures, while cabinet simulation equipment is mostly limited to fixed layouts and cannot flexibly simulate different transformer area environments and diversified fault scenarios.
[0003] In addition, existing simulation systems mostly rely on manual configuration of fault types and equipment information, and the number of fault simulation scenarios is limited, and the application of tools is also restricted. This method lacks automation and cannot generate high-frequency and diversified fault scenarios based on real transformer area data, resulting in relatively single and incomplete training content. SUMMARY
[0004] The present application proposes a tool troubleshooting method under a virtual transformer area in order to better and more diversely restore transformer area scenarios and fault troubleshooting.
[0005] A virtual system is used to achieve it. The virtual system includes a scene module and a tool module. The scene module includes a transformer area module and a deployment module. The tool module includes a tool identification module and a data analysis module. The scene module generates a virtual transformer area scene through the transformer area module to obtain a pre-stored transformer area feature model, and deploys different fault point data, test point data and transformer area basic data in the virtual transformer area scene through the deployment module. The tool module identifies different tool types through the tool identification module, connects the test point in the virtual transformer area scene through the data analysis module to obtain test data, and analyzes the troubleshooting results, thereby achieving tool troubleshooting application under the virtual transformer area. Further, a tool troubleshooting method under a virtual transformer area includes the following steps: A. A virtual transformer area scene is pre-generated through the transformer area module of the scene module. B. Fault point data, test point data and transformer area basic data are deployed in the virtual transformer area scene through the deployment module. C, the tool module identifies the type of tool currently applied through the tool identification module; D, the tool module is connected to the to-be-tested point in the virtual transformer area scene, and the data analysis module obtains the data analysis troubleshooting result of the to-be-tested point.
[0006] The virtual transformer area scene generated by the transformer area module of the virtual system is consistent with the real transformer area scene, including: transformer area total table, branch box, user table, user load, and distribution line to generate multi-level distribution virtual transformer area scene, for example, the multi-level distribution scene of the transformer area total table to the branch box to the user table to the user load of the city network, the multi-level distribution scene of the transformer area total table to the overhead line distribution line to the user table to the user load of the rural network, and the transformer area topology relationship diagram can be generated according to the multi-level distribution scene.
[0007] The fault points deployed by the deployment module of the virtual system include: transformer area total table, branch box, distribution line, and user table, for example, meter shunt, voltage error, current error, etc. are deployed in the transformer area total table and user table, and electricity stealing and grounding fault are deployed in the branch box and distribution line. When the fault point data is not deployed, the normal transformer area data is deployed in these areas; the to-be-tested points deployed include: the transformer area total table and the distribution line side connected with the branch box, the distribution line side connected with the user table of the branch box, and the user table.
[0008] The tool type identified by the tool identification module of the tool module is the troubleshooting tool commonly used in the transformer area, including: transformer area identifier, line loss troubleshooting instrument, electric energy meter calibrator, and multimeter. Different tool types are applied in different to-be-tested points in the virtual transformer area scene, and the data of the to-be-tested points are compared with the basic data of the virtual transformer area scene, the transformer area total table data, and the user table data respectively through the data analysis module to obtain the troubleshooting result.
[0009] Further, the transformer area identifier is mainly used to test the correspondence between the user table and the transformer area total table, and is used to solve the line loss problem caused by the error of the user table in the transformer area; The line loss troubleshooting instrument is mainly used to obtain the electric quantity data of each section in the multi-level transformer area distribution relationship, compare the electric quantity difference between the upper and lower levels, and confirm where the line loss section is, for example, the electric quantity of the transformer area total table should be consistent with the electric quantity of each busbar and the total electric quantity of the user table under the busbar. If they are inconsistent, there is line loss in the section, and the electric quantity of each branch box or each busbar should be consistent with the total electric quantity of the user table under the branch box or busbar. If they are inconsistent, there is line loss in the section; The electric energy meter calibrator mainly compares the AC data of the electric energy meter input and output line with the data collected by the electric energy meter itself to confirm whether the electric energy meter has a fault. The transformer area total table and the user table belong to the electric energy meter.
[0010] The multimeter is mainly used for testing AC data of each power distribution node, checking whether the data of each node is normal, and manually comparing the data collected by the electric energy meter to determine whether the electric energy meter is normal according to the data detected by the multimeter.
[0011] Through the above technical solution, the beneficial effects of the present application are: The present application creates a virtual transformer area scene through a virtual system and simulates various tools for transformer area troubleshooting in the virtual system through a tool module, effectively solving the limitations of existing physical simulation devices, such as single simulation and tool application restrictions. The virtual transformer area scene restores various transformer area scenes and faults, and the troubleshooting of the simulated tool makes the transformer area simulation teaching more flexible and comprehensive.

[0014] Figure 2 It is a scene diagram of a tool troubleshooting method under a virtual transformer area according to the present application. DETAILED DESCRIPTION
[0015] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.
[0016] As shown in the drawings, Figure 1 the present embodiment provides a tool troubleshooting method under a virtual transformer area, which uses a virtual system to realize, the virtual system includes a scene module and a tool module; the scene module includes a transformer area module and a deployment module, and the tool module includes a tool identification module and a data analysis module; The scene module generates a virtual transformer area scene by acquiring a pre-stored transformer area feature model through the transformer area module, and deploys different fault point data, to-be-tested point data and transformer area basic data in the virtual transformer area scene through the deployment module. The tool module identifies different tool types through the tool identification module, acquires test data from the to-be-tested point in the virtual transformer area scene through the data analysis module, analyzes the troubleshooting results, and realizes tool troubleshooting application under the virtual transformer area. Further, a tool troubleshooting method under a virtual transformer area includes the following steps: A. Pre-generate a virtual transformer area scene by the transformer area module of the scene module, which can be generated by historical tested transformer area information, so as to make the virtual transformer area scene consistent with the real transformer area scene, including: transformer area total table, branch box, user table, user load, distribution line to generate multi-level distribution of virtual transformer area scene, for example, multi-level distribution scene of transformer area total table to branch box to user table to user load of city network, multi-level distribution scene of transformer area total table to overhead line distribution line to user table to user load of rural network, and the transformer area topology relationship diagram can be generated according to the multi-level distribution scene.
[0017] B. Deploy fault point data, to-be-tested point data and transformer area basic data in the virtual transformer area scene by the deployment module, including: transformer area total table, branch box, distribution line, user table, for example, deploy meter shunt, voltage error, current error, etc. in the transformer area total table and user table, deploy electricity stealing, grounding fault, etc. in the branch box and distribution line, and deploy normal transformer area data in the area when the fault point data is not deployed; the to-be-tested points deployed include: transformer area total table and distribution line side connected with the branch box, distribution line side connected with the user table of the branch box, user table, etc. C. The tool module identifies the type of tool currently applied by the tool identification module, which is the common troubleshooting tool for transformer area, including: transformer area identifier, line loss troubleshooting instrument, electric energy meter calibration instrument and multimeter. Different tool types are applied in different to-be-tested points in the virtual transformer area scene. The data of the to-be-tested points are obtained by the data analysis module and compared with the basic data of the virtual transformer area scene, the transformer area total table data and the user table data respectively to obtain the troubleshooting result. D. The tool module is connected to the to-be-tested points in the virtual transformer area scene, and the data analysis module obtains the data analysis troubleshooting result of the to-be-tested points.
[0018] Further, the transformer area identifier is mainly used to test the corresponding relationship between the user table and the transformer area total table, and is used to solve the line loss problem caused by the error of house transformer in the transformer area. When the troubleshooting tool selected is the transformer area identifier, the transformer area identifier can be respectively hung on the to-be-tested point of the transformer area total table and the to-be-tested point of the user table. For example, the stored house transformer data on the to-be-tested point of the user table is not the corresponding transformer area total table. At this time, the transformer area identifier on the user table side gives the result of non-transformer area. If the transformer area total table corresponding to the user table is also hung with the transformer area identifier, the transformer area identifier on the user table side can also give the result of the transformer area total table corresponding to the correct corresponding relationship of the user table. When the virtual system is processed, it is only necessary to identify whether the transformer area identifier is hung on the total table corresponding to the correct corresponding relationship of the user table or not. If not, the result of non-transformer area is given, and if yes, the result of the transformer area total table corresponding to the correct corresponding relationship of the user table is given, which is consistent with the actual application effect.
[0019] The line loss troubleshooting instrument is mainly used for obtaining the electric quantity data of each section in the multi-stage distribution relationship, comparing the electric quantity difference between the upper and lower stages, and confirming where the line loss section is. For example, the electric quantity of the total meter of the distribution area should be consistent with the electric quantity of each bus total line and the sum of the electric quantity of the user meter under the bus total line. If the electric quantity is not consistent, the section has line loss. In the virtual system processing, the total electric quantity of the total meter of the distribution area is the sum of the electric quantity consumed by each bus total line and the intermediate fault point. The electric quantity data is stored in the to-be-tested point of the total meter of the distribution area, the to-be-tested point of each bus total line, and the fault point. At this time, the line loss troubleshooting instrument is hung on the to-be-tested point of the total meter of the distribution area and the to-be-tested point of each bus total line, and the pre-stored data of the to-be-tested point is obtained to analyze the line loss. The branch box or each bus total line processes and troubleshoots the data of the subordinate section in the same way.
[0020] The electric energy meter calibrator mainly compares the AC data of the incoming and outgoing lines of the electric energy meter with the data collected by the electric energy meter itself to confirm whether the electric energy meter has a fault. In the virtual system processing, only the correct basic data of the distribution area is deployed on the distribution line to-be-tested point of the total meter of the distribution area or the user meter side, and the fault data of the electric energy meter is deployed on the to-be-tested point of the total meter of the distribution area or the user meter corresponding to the fault. The electric energy meter calibrator obtains the pre-stored AC data of the distribution line to-be-tested point on the electric energy meter side and the pre-stored fault data of the to-be-tested point of the electric energy meter, thereby simulating and verifying the correctness of the electric energy meter.
[0021] The multimeter is mainly used for testing the AC data of each distribution node to check whether the data of each node is normal. The data detected by the multimeter can also be used to manually compare the data collected by the electric energy meter to determine whether the electric energy meter is normal. In the virtual system processing, the basic data can be deployed on the to-be-tested point of the distribution line on the electric energy side, and the fault data such as voltage and current can be set on the electric energy meter. At this time, the electric energy meter displays the fault data, which cannot be determined by testing. At this time, the multimeter obtains the data on the to-be-tested point of the distribution line on the electric energy meter side and simulates the reading of the electric energy meter to manually compare, thereby confirming whether the electric energy meter has a fault.
[0022] Further, the to-be-tested point described above does not refer to a fixed point, but any node of the virtual distribution area can be deployed to meet the use of any troubleshooting tool.
[0023] In order to further illustrate the beneficial effects of the embodiment, reference is made to the following Figure 2 for a more detailed example.
[0024] First, a virtual distribution area scene is deployed through the distribution area module in the scene module, as shown in Figure 2 .
[0025] When the district identification instrument is tested, the deployment module respectively deploys the district total table information on the to-be-tested points A4-A6, B4-B5 of the power distribution line side of the user table 1-5. At this time, the tool identification module of the tool module selects the tool as the district identification instrument, and one district identification instrument is connected to the to-be-tested point 02 of the district total table 1 side, and another is sequentially simulated to be connected to the to-be-tested points A4-A6, B4-B5 of the user side. At this time, the district identification instrument of the user side enables the data analysis module to obtain the storage data of the to-be-tested points A4-A6, B4-B5. When the obtained storage data corresponds to the district total table 1, it is prompted that the district corresponding relationship is the district total table 1. When the data of a to-be-tested point is not the district total table 1, it is prompted that it is not the district. At this time, other district identification instruments can be hung to the to-be-tested points of other district total tables, for example, the to-be-tested point 03 of the district total table 2 side as shown in Figure 2 . At this time, the virtual system detects that the district identification instrument is connected to the to-be-tested point 03 of the district 2, and the district identification instrument of the user side obtains the pre-stored district total table data of the to-be-tested point. When the data corresponds to the district 2, it is given that the user table corresponds to the correct user-district relationship, that is, the district 2.
[0026] When the line loss investigation instrument investigates the line loss, the deployment module respectively deploys the virtual district scene as shown in Figure 2 on each to-be-tested point, the district total table and the user table, and deploys the fault data on the fault point. At this time, the tool identification module of the tool module selects the tool as the line loss investigation instrument, and does the line loss investigation. For example, a fault shunt data is deployed on the fault point A2, so that the loss power of the fault point A2 is generated. At this time, the power of the to-be-tested points 02, A1 and A2 of the upper level is the loss power of the fault point A2 superimposed on the basis power data. Taking the line loss investigation instrument as an example, the to-be-tested points 02 of the district total table 1, the bus to-be-tested points A1 and B1, the branch line to-be-tested points A2, A3 and B2 are hung respectively. At this time, the data analysis module of the line loss investigation instrument obtains the power data of the to-be-tested point 02, which is equal to the data of the to-be-tested points A1 and B1, and gives the investigation result that each bus is normal. Continue to obtain the data. When the power data of the to-be-tested point A2 and the power data of the user table 1 are obtained, it is found that the power data of the to-be-tested point A2 is greater than the power data of the user table 1, because the loss power of the fault point A2 is not recorded by the user table 1. Therefore, the line loss point can be investigated by the segment data, which is consistent with the actual line loss investigation process.
[0027] When the electric energy meter verification instrument is used to investigate the electric energy meter fault, the virtual district scene as shown in Figure 2In the virtual transformer area scene, the transformer area total table 1 is taken as an example. The deployment module deploys a fault, such as current over-limit, at the fault point 01 of the transformer area total table 1. At this time, the corresponding test point 01 of the transformer area total table 1 automatically stores the abnormal data corresponding to the fault, and the correct basic data is deployed at the test point 02 on the power distribution line side of the transformer area total table. At this time, the tool identification module of the tool module selects the tool as the electric energy meter verifier to simulate the verification of whether the transformer area total table 1 is faulty. The electric energy meter verifier is simulated to be connected to the test points 01 and 02. The data analysis module of the electric energy meter verifier respectively acquires the pre-stored data of the test points 01 and 02 for comparison to simulate the correctness of the transformer area total table 1. When the current is over-limit, the current data given by the test point 01 and the current data given by the test point 02 are linear errors, which is consistent with the actual verification effect.
[0028] In the above example, the multimeter can acquire the pre-stored AC data and the AC data of the fault point at each test point, which is used to verify whether the fault point is correct, manually compare the fault, and the like.
[0029] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
