Description

Technical Field

[0001] This invention relates to the field of automated metering technology, and in particular to a method, system, device, and medium for generating automated metering data for low-voltage power grids. Background Technology

[0002] Low-voltage distribution networks are located at the end of the entire power grid and are characterized by wide distribution, complex power supply and consumption environment, and high difficulty in operation and maintenance. However, there is a lack of intelligent monitoring methods for low-voltage distribution transformer areas, which constitutes a blind spot in the intelligent monitoring of distribution networks.

[0003] Therefore, to monitor the real-time status of low-voltage distribution networks, it is usually necessary to deploy automation terminals (gateways). However, the number of automation terminals (gateways) is huge. According to the current automation and data correspondence verification methods of terminals sending data to the master station, each data collection point needs to be checked one by one in the automation point table simultaneously drawn up at both ends of each terminal and the master station. This is a huge workload, requires a large amount of investment, and has extremely high operation and maintenance costs, which greatly restricts the effective implementation of automation in low-voltage distribution networks.

[0004] However, existing technology verifies each collection point by creating a communication point list. But the communication point list between the low-voltage automation terminal and the main station is manually compiled in the low-voltage automation system. When a new automation point list is created or there are changes, the automation point list needs to be created or modified manually on the terminal and the main station, resulting in low work efficiency. Summary of the Invention

[0005] This invention provides a method, system, device, and medium for generating automation point tables for low-voltage power grids. It solves the technical problem that existing low-voltage automation systems rely on manual compilation of communication point tables between low-voltage automation terminals and the master station. When new automation point tables are created or changes occur, manual creation or modification of automation point tables is required on both the terminal and the master station, resulting in low work efficiency.

[0006] The first aspect of this invention provides a method for generating automated point meters for low-voltage power grids, comprising:

[0007] In response to the received request to create an automated point table, obtain the low-voltage node ledger of the area corresponding to the request to create an automated point table;

[0008] According to the preset node order, assign telemetry groups to each node in the low-voltage node ledger of the transformer area, and generate a telemetry point table.

[0009] According to the preset node order, remote signaling points are assigned to each node in the low-voltage node ledger of the transformer area, and a remote signaling point table is generated.

[0010] An initial automated point table is generated using the telemetry point table and the remote signaling point table;

[0015] If so, then execute the step of assigning telemetry groups to each node in the low-voltage node ledger of the transformer area according to the preset node order and generating a telemetry point table;

[0016] If not, a message will be displayed indicating that the number of nodes corresponding to the low-voltage node ledger in the transformer area has exceeded the limit, and the creation of the automated node table will be terminated.

[0017] Optionally, the step of assigning telemetry groups to each node in the low-voltage node ledger of the transformer area according to a preset node order and generating a telemetry point table includes:

[0019] Send the updated low-voltage node ledger of the transformer area to the terminal corresponding to the updated low-voltage node ledger of the transformer area.

[0020] The terminal sorts the low-voltage node ledger of the target transformer area according to the preset node order to generate the low-voltage node ledger of the target transformer area.

[0021] Telemetry groups are sequentially assigned to each node in the low-voltage node ledger of the target area to generate a telemetry point table.

[0022] Optionally, the step of sorting the low-voltage node ledger of the target transformer area according to the preset node order through the terminal to generate the low-voltage node ledger of the target transformer area includes:

[0023] Determine whether the terminal has received the updated low-voltage node ledger for the distribution area;

[0024] If not, return to the step of sending the updated low-voltage node ledger of the transformer area to the terminal corresponding to the updated low-voltage node ledger of the transformer area;

[0025] If so, determine whether the terminal has an initial low-voltage node ledger for the distribution area;

[0026] If not, the updated low-voltage node ledger of the transformer area is sorted according to the preset node order to generate the low-voltage node ledger of the target transformer area.

[0027] If so, the initial low-voltage node ledger for the transformer area is replaced, and the nodes in the updated low-voltage node ledger for the transformer area are sorted according to the preset node order to generate the low-voltage node ledger for the target transformer area.

[0028] Optionally, the step of sequentially assigning telemetry groups to each node in the low-voltage node ledger of the target distribution area and generating a telemetry point table includes:

[0029] Group the telemetry points corresponding to the preset number of telemetry points to generate multiple initial telemetry groups;

[0030] The telemetry points in each initial telemetry group are sorted and numbered to generate a target telemetry group and multiple telemetry point numbers in the target telemetry group.

[0031] Each of the target telemetry groups is sequentially assigned to a node in the low-voltage node ledger of the target transformer area, thereby generating a telemetry point table.

[0032] Optionally, the step of sending verification information to the initial automated point table and obtaining feedback information from the telemetry points and remote signaling points corresponding to the initial automated point table includes:

[0033] Send verification information to each telemetry point corresponding to the initial automated point table;

[0034] The telemetry devices corresponding to each telemetry point respond to the verification information and provide feedback, generating multiple first feedback messages;

[0035] Send verification information to each remote signaling point corresponding to the initial automated point table;

[0038] The main station determines whether the telemetry value corresponding to each of the first feedback messages is consistent with the telemetry point number value corresponding to the verification information.

[0039] If not, a point table creation failure message will be generated, and the automated point table creation process will end.

[0040] If so, determine whether the order of remote signaling prompts corresponding to each second feedback information corresponds to the remote signaling point number corresponding to the verification signal;

[0041] If not, a point table creation failure message will be generated, and the automated point table creation process will end.

[0042] If so, a point table creation success message is generated, and the initial automated point table is identified as the target automated point table.

[0061] This invention provides a method, system, device, and medium for generating low-voltage power grid automation point tables. It addresses the technical problem that existing low-voltage automation systems rely on manual compilation of communication point tables between low-voltage automation terminals and the master station. When new automation point tables are created or modified, manual creation or modification of the automation point tables at the terminal and the master station is required, resulting in low work efficiency.

[0062] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0063] Please see Figure 1 , Figure 1 The flowchart illustrates the steps of a low-voltage power grid automation point meter generation method provided in Embodiment 1 of the present invention.

[0064] This invention provides a method for generating automated point meters for low-voltage power grids, comprising the following steps:

[0065] Step 101: Respond to the received request to create an automated point table and obtain the low-voltage node ledger of the corresponding area.

[0066] It should be noted that creating an automated point table request refers to a request for the corresponding point table for the corresponding transformer area.

[0067] The low-voltage node ledger of a transformer area refers to the ledger of nodes (switches, disconnectors) in a certain transformer area. The low-voltage node ledger of a transformer area includes the power supply bureau where the transformer area is located, the power supply unit, the transformer area number, and each node. The nodes are sorted in a certain order, and a topology number is generated according to the topological relationship of each node.

[0068] In this embodiment of the invention, the low-voltage node ledger of the corresponding transformer area is obtained by responding to the request to create an automated point table.

[0069] Step 102: Assign telemetry groups to each node in the low-voltage node ledger of the transformer area according to the preset node order, and generate a telemetry point table.

[0070] It should be noted that the preset node order is based on the same sorting method (ascending or descending), and the specific choice of ascending or descending order is determined by the staff as needed.

[0071] Each telemetry group consists of 12 telemetry points, and each telemetry point corresponds to a telemetry point number.

[0072] In a specific embodiment, the nodes on the low-voltage node ledger of the transformer area are sorted according to a certain node order, and 12 telemetry points are assigned to each sorted node to generate a telemetry point table. The telemetry point table includes a sorting number, the corresponding node number, and multiple telemetry point numbers corresponding to each node.

[0073] Step 103: Assign remote signaling points to each node in the low-voltage node ledger of the transformer area according to the preset node order, and generate a remote signaling point table.

[0074] It should be noted that each remote signaling point corresponds to a remote signaling point number.

[0075] In this embodiment of the invention, the nodes in the low-voltage node ledger of the transformer area are sorted according to a certain node order, and a remote signaling point is assigned to each sorted node to generate a remote signaling point table. The remote signaling point table includes a sorting number, a remote signaling point number, the node corresponding to the remote signaling point number, and the corresponding node number.

[0076] Step 104: Generate an initial automated point table using the telemetry point table and the remote signaling point table.

[0077] It should be noted that the initial automated point table refers to the unverified, raw generated automated point table.

[0078] In a specific embodiment, an initial automated point table can be generated by combining the telemetry point table and the remote signaling point table.

[0079] Step 105: Send verification information to the initial automated point table and obtain feedback information from the telemetry points and remote signaling points corresponding to the initial automated point table.

[0080] It should be noted that the verification information refers to the information on the correspondence verification of each telemetry point and the information on the correspondence verification of each remote signaling point.

[0081] Feedback information refers to the feedback instructions issued by the equipment corresponding to the telemetry point and the remote signaling point in response to the verification information.

[0082] In a specific embodiment, by sending verification information to the initial automated point table, wherein the verification information includes the telemetry value corresponding to each telemetry point number and the remote signaling point value set according to the remote signaling order on the remote signaling point table, and sending them to each telemetry point and remote signaling point respectively, feedback information made by the device response verification information corresponding to each telemetry point and remote signaling point is obtained.

[0083] Step 106: Verify the feedback information through the main station to determine the target automation point table.

[0084] In this embodiment of the invention, the initial automated point table is determined as the target automated point table by verifying each feedback information through the main station and confirming that the feedback information is correct.

[0085] This invention addresses the technical problem in existing low-voltage automation systems where communication point tables between low-voltage automation terminals and the main station are manually compiled. This requires manual creation or modification of the automation point table on both the terminal and the main station, leading to low work efficiency. This invention eliminates the need for manual configuration of automated point tables at the main station and terminals, thereby reducing the workload of automation personnel and eliminating the risk of errors during point table configuration. It also eliminates the need to send automation maintenance personnel to the site to verify real-time data with the main station personnel, thus eliminating the risks associated with transportation and on-site work for automation personnel. Furthermore, it eliminates the need for manual input of data telemetry and remote signaling at the terminal side, reducing the investment in tools and equipment, lowering costs, and improving work efficiency.

[0086] Please see Figure 2-5 , Figure 2 This is a flowchart illustrating the steps of a low-voltage power grid automation point meter generation method provided in Embodiment 2 of the present invention.

[0087] This invention provides a method for generating automated point meters for low-voltage power grids, comprising the following steps:

[0088] Step 201: Respond to the received request to create an automated point table and obtain the low-voltage node ledger of the corresponding area.

[0089] It should be noted that, as Figure 3 As shown, the low-voltage node ledger for a transformer area refers to the ledger of nodes (switches, disconnectors) in a specific transformer area. This ledger includes the power supply bureau where the transformer area is located, the power supply unit, the transformer area's identification number, and each node, arranged in a specific order. Figure 4 As shown, topology numbers are generated according to the topological relationships of each node in the low-voltage structure diagram of the transformer area.

[0090] Specifically, such as Figure 3As shown, each node is represented by "K" and 10 digits. The topology number of the main switch 4081 is "K0000000000". Each level of node after the main switch is represented by two digits, from left to right: "01", "02", "03", etc. Lower-level nodes inherit the number of the upper-level nodes, and all digits after the current level node are "0". The topology number of the first-level node 4061 switch is "K0100000000", the number of the first-level node 4071 switch is "K0200000000", and the number of the first-level node 4072 switch is "K0300000000". The topology number of the second-level switch 7101 connected to the first-level switch 4071 is "K0201000000". Similarly, the topology number of the second-level switch 7201 connected to the first-level switch 4072 is "K0301000000".

[0091] Before performing step 202, this method also includes the following steps S11-S13:

[0092] S11. Determine whether the number of nodes corresponding to the low-voltage node ledger in the transformer area is less than or equal to the node threshold.

[0093] S12. If so, then execute the steps of assigning telemetry groups to each node in the low-voltage node ledger of the transformer area according to the preset node order and generating a telemetry point table.

[0094] S13. If not, prompt that the number of nodes corresponding to the low-voltage node ledger in the transformer area has exceeded the limit, and end the creation of the automated node table.

[0095] It should be noted that the node threshold is 341, which means that the maximum number of low-voltage nodes per transformer area is 341.

[0096] In a specific embodiment, such as Figure 5 As shown, first determine if the number of nodes corresponding to the low-voltage node ledger in this area is greater than 341. If it is greater than 341, issue a prompt message "The number of nodes corresponding to the low-voltage node ledger in this area exceeds the limit" and exit the automated point table creation process; if it is less than or equal to 341, continue to the next step.

[0097] Step 202: Sort the nodes in the low-voltage node ledger of the transformer area according to the preset node order through the main station, and generate an updated low-voltage node ledger of the transformer area.

[0098] In a specific embodiment, such as Figure 3 As shown, the nodes in the low-voltage node ledger of the transformer area are sorted according to a certain node order to generate and update the low-voltage node ledger of the transformer area.

[0099] Step 203: Send the updated low-voltage node ledger of the transformer area to the terminal corresponding to the updated low-voltage node ledger of the transformer area.

[0100] In a specific embodiment, the updated low-voltage node ledger for the distribution area is sent to the corresponding terminal.

[0101] Step 204: Sort the low-voltage node ledger of the target transformer area according to the preset node order through the terminal, and generate the low-voltage node ledger of the target transformer area.

[0102] Optionally, step 204 includes the following steps S21-S25:

[0103] S21. Determine whether the terminal has received the updated low-voltage node ledger for the distribution area;

[0104] S22. If not, return to the step of sending the updated low-voltage node ledger of the transformer area to the terminal corresponding to the updated low-voltage node ledger of the transformer area.

[0105] S23. If yes, then determine whether the terminal has an initial low-voltage node ledger for the distribution area;

[0106] S24. If not, sort the low-voltage node ledger of the updated transformer area according to the preset node order and generate the low-voltage node ledger of the target transformer area.

[0107] S25. If so, replace the initial low-voltage node ledger of the transformer area, and sort the nodes of the updated low-voltage node ledger of the transformer area according to the preset node order to generate the low-voltage node ledger of the target transformer area.

[0108] In a specific embodiment, such as Figure 5 As shown, firstly, it is determined whether the updated low-voltage node ledger for the distribution area has been successfully sent to the corresponding terminal. If the sending is unsuccessful, the updated low-voltage node ledger for the distribution area is resent to the terminal. If the sending is successful, the terminal has successfully received the updated low-voltage node ledger for the distribution area. Secondly, it is determined whether the terminal already has an initial low-voltage node ledger for the distribution area. If no initial low-voltage node ledger exists, the updated low-voltage node ledger is sorted according to a certain node order to generate the target low-voltage node ledger for the distribution area. If an initial low-voltage node ledger exists, the updated low-voltage node ledger replaces the old initial low-voltage node ledger for the distribution area, and the updated low-voltage node ledger is then sorted according to a certain node order to generate the target low-voltage node ledger for the distribution area.

[0109] Step 205: Assign telemetry groups to each node in the low-voltage node ledger of the target area in sequence, and generate a telemetry point table.

[0110] Optionally, step 205 includes the following steps S31-S33:

[0111] S31. Group the telemetry points corresponding to the preset number of telemetry points to generate multiple initial telemetry groups;

[0112] S32. Sort and number the telemetry points in each initial telemetry group to generate the target telemetry group and the corresponding telemetry point numbers in the target telemetry group.

[0113] S33. Assign each target telemetry group to each node in the low-voltage node ledger of the target area in sequence, and generate a telemetry point table.

[0114] It should be noted that the preset number of telemetry points is 12. Each telemetry group has 12 telemetry points, and each telemetry point in each telemetry group has a telemetry point number.

[0115] In a specific embodiment, the telemetry point number starts from the first node in the low-voltage node ledger of the target area (e.g., ...). Figure 3 Starting with switch 4081, each node is assigned 12 telemetry points in the following order: PA, PB, PC, QA, QB, QC, UA, UB, UC, IA, IB, IC. That is, the PA telemetry point number of the first node is 1 (starting from 1 according to the telemetry point number corresponding to the telemetry point table), the PC telemetry point number of the second node (switch 4061) is 15 (1*12+3), the IC telemetry point number of the third node (switch 4071) is 36 (2*12+12), and so on, to generate the telemetry point table.

[0116] Step 206: Assign remote signaling points to each node in the low-voltage node ledger of the transformer area according to the preset node order, and generate a remote signaling point table.

[0117] In this embodiment of the invention, the nodes on the low-voltage node ledger of the distribution area are sorted according to a certain node order, and a remote signaling point is assigned to each sorted node. For example, starting from the first node (4081 switch), each node is assigned 1 remote signaling point to send the node's energized information; that is, the remote signaling point number of the first node is 1 (starting from 1 according to the remote signaling point number on the remote signaling point table), the remote signaling point number of the second node (4061 switch) is 2, the remote signaling point number of the third node (4071 switch) is 3, and so on, to generate the remote signaling point table.

[0118] Step 207: Generate an initial automated point table using the telemetry point table and the remote signaling point table.

[0119] In this embodiment of the invention, the specific implementation process of step 207 is similar to that of step 104, and will not be repeated here.

[0120] Step 208: Send verification information to the initial automated point table and obtain feedback information from the telemetry points and remote signaling points corresponding to the initial automated point table.

[0121] Optionally, step 208 includes the following steps S41-S44:

[0122] S41. Send verification information to each telemetry point corresponding to the initial automated point table;

[0123] S42. Generate multiple first feedback messages by responding to and providing feedback through the telemetry equipment corresponding to each telemetry point and the verification information.

[0124] S43. Send verification information to each remote signaling point corresponding to the initial automated point table;

[0125] S44. The remote signaling equipment corresponding to each remote signaling point responds to the verification information and makes feedback, generating multiple second feedback messages.

[0126] In a specific embodiment, when the master station initiates the telemetry point table correspondence verification information, the terminal sends the same value as the telemetry point number corresponding to all telemetry points, that is, telemetry point 1 sends "1", telemetry point 2 sends "2", and so on.

[0127] Specifically, when the main station initiates the remote signaling point table correspondence verification information, the terminal first sets all remote signaling points to "0", and then sets one point to "1" every 5 seconds (interval can be set) according to the order of the remote signaling point table, starting from the first remote signaling point, and sends it to the main station.

[0128] Step 209: Verify the feedback information through the main station to determine the target automation point table.

[0129] Optionally, the feedback information includes first feedback information and second feedback information; step 209 includes the following steps S51-S55:

[0130] S51. The main station determines whether the telemetry value corresponding to each first feedback information is consistent with the telemetry point number value corresponding to the verification information.

[0131] S52. If not, generate a point table creation failure message and end the automated point table creation process.

[0132] S53. If so, determine whether the order of remote signaling prompts corresponding to each second feedback information corresponds to the remote signaling point number corresponding to the verification signal;

[0133] S54. If not, generate a point table creation failure message and end the automated point table creation process.

[0134] S55. If so, generate a point table creation success message and set the initial automated point table as the target automated point table.

[0135] In this embodiment of the invention, after the master station receives the first feedback information, it checks whether the value received by each telemetry point (that is, the feedback instruction made in response to the value) is the same as the telemetry point number. If all the requirements are met, the correspondence verification is deemed to have passed. Otherwise, the verification is deemed to have failed, and a non-corresponding point is prompted. The point table creation failure message is generated, that is, the prompt content "Automatic point table generation failed" appears, and the automatic point table creation ends.

[0136] After receiving the second feedback information, the main station checks whether the order of the received remote signaling prompts is the same as the order of the remote signaling point numbers of the main station's remote signaling points. It then determines whether the order of the remote signaling point tables of both parties is consistent. If they are all consistent, the correspondence verification is deemed to have passed, and a point table creation success message is generated. The initial automated point table is then identified as the target automated point table. Otherwise, the verification is deemed to have failed, and a message indicating that the point numbers do not correspond is displayed. A point table creation failure message is generated, which is "Automated point table creation failed" message. The creation of the automated point table then ends.

[0137] This invention addresses the technical problem in existing low-voltage automation systems where communication point tables between low-voltage automation terminals and the main station are manually compiled. This requires manual creation or modification of the automation point table on both the terminal and the main station, leading to low work efficiency. This invention eliminates the need for manual configuration of automated point tables at the main station and terminals, thereby reducing the workload of automation personnel and eliminating the risk of errors during point table configuration. It also eliminates the need to send automation maintenance personnel to the site to verify real-time data with the main station personnel, thus eliminating the risks associated with transportation and on-site work for automation personnel. Furthermore, it eliminates the need for manual input of data telemetry and remote signaling at the terminal side, reducing the investment in tools and equipment, lowering costs, and improving work efficiency.
