Description

Technical Field

[0001] The present invention relates to the technical field of power monitoring, and particularly to a method and device for testing the cross-district and cross-household of electric meter collection strings. Background Art

[0002] With the rapid economic development and the increasing social demand for electricity, the scale of the power system is constantly expanding. The HPLC collection method currently accounts for more than 90% of the low-voltage collection coverage rate in the State Grid. The application methods of the HPLC collection method vary in different provinces. For example, in Zhejiang region, the plug-and-play method is generally adopted. When collecting electric meters, the reporting concentrator is not fixed. The channel with better current signal is preferentially used for networking. During the subsequent networking process, due to the unstable network channel, there may be a situation where the reporting channel is changed, that is, the affiliated concentrator is changed. This situation is called HPLC cross-district. Other provinces use the whitelist method to issue concentrators, that is, the district files are issued to the concentrators as the concentrator files. When applying based on HPLC, these two modes need to be compatible.

[0003] Household meter relationship: It refers to the corresponding relationship between each electric meter installed centrally in the urban and rural residential electric meter boxes and each actual household. Cross-household means that the household-meter corresponding relationship is incorrect, which will lead to incorrect payment by users. In the actual environment, the post-meter line generally adopts the method of being buried in the wall to access the user's home. At this time, due to incorrect identification or ineffective acceptance means, there is a certain probability of incorrect household-meter relationship. When the household-meter relationship is incorrect, the electricity fee used by the user will be measured on the electric meters of other users, which is likely to cause disputes.

[0004] Existing cross-household acceptance methods: Traditionally, it is to confirm by pulling the switch one by one, which brings inconvenience to users' lives. At the same time, the test workload is large and it is easy to miss. The prior art discloses "Patent No. ZL201510606891, a device and method for identifying household-meter relationship", which realizes household-meter identification through an identification host, an identification slave, a forwarding device, a receiving device, and a background device. The types of devices applied in this technology are many and the operation is complex, and the test efficiency is still not high. And there are many users in the low-voltage district. The workload of testing each household one by one by one person is large, easy to get tired and make mistakes, and multiple people are needed to jointly test to improve the acceptance efficiency.

[0005] With the wide application of the HPLC communication technology means in the low-voltage district, it provides the necessary convenience for data acquisition for the present invention and improves the usability. The present invention can adapt to the problem of cross-district of electric meter collection and can perform cross-household testing in various HPLC test environments, improving the operation and maintenance efficiency and ensuring the safety of people's lives and property. Summary of the Invention

[0006] The object of the present invention is to provide a method and a testing device for testing the cross-household connection of meter collection in different substations in a district, which can realize the identification of cross-household connection in low-voltage substations and is applicable to various HPLC collection methods, improving the testing efficiency and applicability.

[0007] To achieve the above object, the present invention adopts the following technical solutions: The present invention provides a method for testing the cross-household connection of meter collection in different substations in a district, characterized by including the following steps: Obtain the list of user files of multiple substations in the community; Obtain the meter files in the concentrators of multiple substations in the community; Compare the user files of the substation with the meter files in the concentrator to obtain the concentrator files to which the user files belong; Conduct a test on the correspondence between the household meter, when a specific load occurs in the corresponding user's home, send corresponding commands according to the concentrator to which the user file belongs to read the meter, and obtain the power change of the corresponding meter to determine whether there is a problem of cross-household connection; When the meter files in the concentrator change due to re-searching for meters or cross-substation problems, re-obtain the concentrator meter files and conduct the comparison again to update the concentrator files to which the user file meters belong to ensure the normal progress of the test.

[0008] Furthermore, a method for testing the cross-household connection of meter collection in different substations in a district is applied to the cross-substation collection of HPLC, and the meter data is collected according to the currently affiliated collection concentrator of the meter.

[0009] Furthermore, the list of user files of the substation is obtained through the collection system of the power supply company, and the meter files in the concentrator are obtained by connecting to the concentrator to read the concentrator meter files in real time.

[0010] Even further, compare the list of user files with the meter files in the concentrator to determine the concentrator to which the meters in the list of user files of the substation belong. When conducting the household meter test, first query the concentrator files to which the current meter belongs and automatically send commands to the corresponding concentrator to read the meter data.

[0011] On the other hand, the present invention provides a testing device for testing the cross-household connection of meter collection in different substations in a district, including: a master station system, a management terminal, and a testing terminal; The master station system includes: a recording module, a control module, and an analysis module; The management terminal includes: a reading module, a communication module; The testing terminal includes: a testing module, a communication module; The main station system recording module prestores the list of user files in the substation area. The control module sends instructions to the management terminal reading module to read the meter files in the concentrator and save them to the recording module. The analysis module compares the list of user files in the substation area with the meter files in the concentrator to confirm the concentrator to which the meters in the list of user files in the substation area belong and records it in the recording module. At the same time, during the cross-connection test, the control module of the main station system sends instructions to the test terminal to control the test module to generate a specified load. At the same time, the control module of the main station system specifies the management terminal according to the data in the recording module to control the corresponding concentrator to perform meter reading, so as to ensure the normal progress of the cross-connection test in the case of HPLC cross-substation area.

[0012] Further, the list of user files in the substation area prestored by the main station system includes: user address and corresponding meter asset number information.

[0013] Further, the concentrator meter file information obtained by the management terminal reading module includes meter asset number information.

[0014] Furthermore, the main station system controls the test terminal and the management terminal respectively. When the test terminal generates a specific load, it controls the management terminal to read the corresponding meter load change through the concentrator. If the meter load change is consistent with the load change of the test terminal, there is no cross-connection; if the meter load change is inconsistent with the load change of the test terminal or there is no load change, there is a cross-connection.

[0015] Furthermore, when judging whether there is a cross-connection according to the meter load change, it is also possible to judge whether there is a problem of reverse connection of the incoming and outgoing lines of the meter according to the read meter power. For example, if the instantaneous active power of the meter is negative, the incoming and outgoing lines of the meter are reversely connected at this time. If the instantaneous active power of the meter is positive, the incoming and outgoing lines of the meter are normally connected at this time.

[0016] After adopting the above technical solution, the beneficial effects of the present invention compared with the prior art are: When the present invention conducts cross-connection investigation, the operator only needs to install the management terminal on the required test community. The investigation device automatically confirms the concentrator to which the meter belongs according to the list of user files in the substation area and the concentrator file, ensuring that cross-connection investigation can be carried out in various acquisition scenarios, adapting to various HPLC acquisition scenarios, improving the investigation efficiency and saving labor costs.

[0021] When applied to the cross-transformer area collection of HPLC, the electric meter data is collected according to the currently affiliated collection concentrator of the electric meter.

[0022] Furthermore, the list of user files of the transformer area is obtained through the power supply company's collection system, and the electric meter files in the concentrator are obtained by connecting to the concentrator to read the electric meter files in real time.

[0023] Furthermore, compare the list of user files with the electric meter files in the concentrator to determine the concentrator to which the electric meter in the list of user files of the transformer area belongs. When performing the household meter test, first query the concentrator files to which the current electric meter belongs, and automatically send a command to the corresponding concentrator to read the electric meter data.

[0024] Embodiment 2, the present invention provides a device for testing the cross-household of electric meter collection in series of transformer areas, including: a master station system, a management terminal, and a test terminal; The master station system includes: a recording module, a control module, and an analysis module; The management terminal includes: a reading module, a communication module; The test terminal includes: a test module, a communication module; The main station system recording module pre-stores the list of user files in the transformer area.

[0027] Furthermore, the main station system controls the test terminal and the management terminal respectively. When the test terminal generates a specific load, it controls the management terminal to read the corresponding meter load change through the concentrator. The meter load change is consistent with the load change of the test terminal, and there is no cross-connection; the meter load change is inconsistent with the load change of the test terminal or there is no load change, then there is a cross-connection.

[0028] Furthermore, when judging whether there is a cross-connection according to the meter load change, it is also possible to judge whether there is a problem of reverse connection of the incoming and outgoing lines of the meter according to the read meter power.
