Description

Technical Field

[0001] The present application relates to the technical field of power system maintenance, and in particular to a method, system and terminal for verifying the consistency of graphic, digital and analog of power grid equipment assets. Background Art

[0002] With the continuous development of the power grid system, various electrical equipment is constantly updated in terms of software and hardware. In order to manage and operate the power grid system more comprehensively and systematically, the management departments of each regional power grid have put forward a new power grid management concept, namely "one map of the power grid", and it has been gradually implemented and improved. One map of the power grid refers to integrating various information such as various equipment, lines, substations, etc. of the power grid in a graphical way to form a comprehensive, intuitive and dynamic power grid view. This graphical management method helps power grid operators better monitor, analyze and manage the power grid, and improve the operation efficiency and safety of the power grid.

[0003] And each large-scale update iteration in the power grid that is not the first time has basically undergone equipment replacement, parameter change, connection relationship change, operation mode change, etc. Operators need to virtualize the updated content into specific units in the one map of the power grid and upload them to the corresponding positions in the one map of the power grid, so that operators can monitor the operation status of the updated content through the workbench in the power grid background.

[0004] Generally speaking, operators need to reconstruct the power grid topology diagram of the current updated content according to the verification list to facilitate the verification of equipment information by operators. However, the newly constructed power grid topology diagram is generated based on the updated content on the verification list. However, there are certain regional differences in the updated content of different regional power grid systems. Therefore, there are certain limitations in the current power grid topology diagram with the newly constructed power grid topology diagram by operators, which reduces the work efficiency of operators. Summary of the Invention

[0005] In order to improve the work efficiency of operators in verifying the updated content of the power grid, the present application provides a method, system and terminal for verifying the consistency of graphic, digital and analog of power grid equipment assets.

[0006] In the first aspect, a method for verifying the consistency of graphic, digital and analog of power grid equipment assets provided by the present application adopts the following technical solutions:

[0007] A method for verifying the consistency of graphic, digital and analog of power grid equipment assets includes:

[0008] Obtain a re-verification list and the current power grid topology diagram of the area corresponding to the re-verification list;

[0009] Based on the re-verification list, construct an initial power grid topology diagram corresponding to the re-verification list;

[0010] Overlap and compare the current power grid topology diagram and the initial power grid topology diagram to generate multiple differential units and multiple identical units;

[0011] Using the current power grid topology diagram as the base, mark multiple differential units and multiple identical units to generate a verification topology diagram.

[0012] Through the above technical solution, the re-verification list includes the specific content of this update, such as specific updated equipment, specific equipment locations, the distribution areas to which the equipment belongs, changes in the connection relationships of the updated equipment, and changes in operating parameters, etc. The current power grid topology diagram corresponding to the area of the re-verification list refers to the basic layout structure diagram currently in operation, composed of power grid nodes (such as power plants, substations, electrical loads, etc.) and the transmission lines and power equipment connected thereto. Grid operation and maintenance personnel can perform simulation work such as power flow calculation, fault diagnosis, and dynamic simulation by monitoring the current power grid topology diagram in the background, which helps in the monitoring and analysis of the power grid operation status and improves the safety and reliability of the power grid operation.

[0013] Based on the content updated this time and the most basic structural framework of the power grid system, generate an initial power grid topology diagram corresponding to the re-verification list (which has been specifically described in relevant patent documents and the prior art and will not be elaborated here). Then, overlap and compare the current power grid topology diagram and the initial power grid topology diagram to generate multiple differential units (contents with obvious differences) and multiple identical units (contents with no obvious differences), and mark the multiple differential units and multiple identical units on the current power grid topology diagram to generate a verification topology diagram.

[0014] The operator synchronizes the verification topology diagram to the mobile terminal. By using the verification topology diagram to verify the content updated this time, the differential units and identical units can be highlighted. Compared with using the re-constructed initial power grid topology diagram, the operator can perform the verification more pertinently, thus improving the work efficiency of the operator in checking the power grid update content.

[0015] In a preferred example of the present application, it can be further configured that after generating the verification topology diagram, the following processing steps are further included:

[0016] After completing the verification according to the verification topology diagram, fuse the verification result and the verification topology diagram to form a topology diagram to be verified;

[0017] Send an audit request for the topology diagram to be verified to the power grid background;

[0018] If the review result of the review request is passed, the verification result will be uploaded to the current power grid topology diagram to update the current power grid topology diagram.

[0019] Through the above technical solution, after the operator arrives at the equipment site and completes the verification of the current update content according to the verification topology diagram, the verification result and the verification topology diagram are fused. Here, it can be understood that the verification result is input into the verification topology diagram to form a topology diagram to be reviewed, and a review request for the topology diagram to be reviewed is sent to the power grid background.

[0020] Since the verification topology diagram is generated based on the current power grid topology diagram, the topology diagram to be reviewed and the current power grid topology diagram have a higher degree of coincidence, the passing rate of the review is higher, and the possibility of the operator performing secondary verification is reduced.

[0021] After the review request for the topology diagram to be reviewed is passed, the current verification result is directly uploaded to the current power grid topology diagram to update the current power grid topology diagram, thereby completing the current verification.

[0022] In a preferred example of the present application, it can be further configured that after generating a plurality of difference units and a plurality of identical units, the following processing steps are further included:

[0023] According to the connection relationship of the verification content, establish a plurality of connection level trees of the verification content;

[0024] Based on the plurality of connection level trees, generate a plurality of sub-verification lists, and each sub-verification list includes a plurality of the difference units and a plurality of the identical units;

[0025] Based on the plurality of difference units included in the sub-verification list, calculate the complexity value of each sub-verification list;

[0026] Based on the numerical size of the complexity values of the plurality of sub-verification lists, set different verification priorities for each sub-verification list.

[0027] Through the above technical solution, the connection relationship of the verification content refers to the connection relationship between the current power grid update contents, which can be the connection between a certain device and other devices (such as signal reception and transmission). Establish a plurality of connection level trees of the verification content. The connection level tree refers to the affiliated devices of a plurality of connection levels related to a certain device (for example, an intelligent feeder terminal can control the opening and closing of the pole-mounted circuit breaker, the opening and closing state of the pole-mounted circuit breaker can be monitored by a monitoring device, then the above intelligent feeder terminal, pole-mounted circuit breaker, and detection device are the three levels in sequence of the connection level tree, and so on).

[0028] Based on multiple connection level trees, multiple sub-verification lists are generated. Here, it can be understood that one sub-verification list can include multiple connection level trees, which also correspond to multiple difference units. Then, by calculating the complexity value of the sub-verification list (representing the complexity of the connection relationship), the complexity of the verification content of the sub-verification list can be known. The higher the complexity, the larger the scope involved in the current power grid update content, and the more pre-verification is needed. Therefore, the priority of the sub-verification list can be set according to the complexity value in this way, that is, the larger the complexity value, the higher the verification priority of the corresponding sub-verification list.

[0029] In a preferred example of the present application, it can be further configured that calculating the complexity value of each of the sub-verification lists includes the following processing steps:

[0030] Set different complexity bases for different levels of the connection level tree;

[0031] Based on the complexity base and the radiation value of each level of the connection level tree, calculate the complexity value of each sub-verification list.

[0032] Through the above technical solution, there are certain differences in the importance of power equipment at different levels of the connection level tree. For example, for an intelligent feeder terminal, it can control the opening and closing of the pole-mounted circuit breaker, and it is at a relatively important level itself. While the backup battery used to provide backup energy for the intelligent feeder terminal, although there is a connection relationship with the intelligent feeder terminal, it is not absolutely important. Therefore, the backup battery is at a relatively lower level in the connection level tree (which level a specific device is at in the connection level tree can be set in advance, or the relative connection level span between devices can be set).

[0033] Therefore, different complexity bases need to be set for devices at different levels of the connection level tree, which means that the importance of devices at different levels of the connection level tree is different. For example, for the first level, the complexity base is set to 5a, for the second level, the complexity base is set to 4a, and so on. Of course, the difference in complexity bases between adjacent levels is not strictly an arithmetic decrease, and it can be set and flexibly adjusted according to the actual situation.

[0034] Based on the complexity base and the radiation value of each level of the connection level tree (the radiation value refers to the number of radiations of adjacent connection relationships subordinate to each device main body), calculate the complexity value of each sub-verification list. According to the complexity value, the complexity of the sub-verification list can be analyzed, which is also convenient for setting the verification priority.

[0035] In a preferred example of the present application, it can be further configured that the complexity value of the sub-verification list is calculated using the following formula:

[0036] K = k1 xa + k 2 ya + … + k n za

[0037] Where K is the complexity value of the sub - check list, and k 1 、k 2 、k n are the radiation values of different levels of the connection level tree. xa, ya, and za are the complexity bases of different levels of the connection level tree, where x > y > z. The complexity value of the sub - check list is the sum of the complexity values of the connection level tree corresponding to the differential units included in the sub - check list.

[0038] Through the above technical solution, the radiation value refers to the radiation quantity of the adjacent connection relationships subordinate to each device body. For the first level of the connection level tree, the product of the radiation value k 1 and the complexity base xa of the first level is the complexity value of the first level. By analogy, the sum of the complexity values of multiple levels is the complexity value of this connection level tree. Adding the complexity values of multiple connection level trees included in the sub - check list is the complexity value of the sub - check list.

[0039] In a preferred example of the present application, it can be further configured that different check priorities are set for each sub - check list based on the numerical magnitudes of the complexity values of multiple sub - check lists, including the following processing steps:

[0040] If there are sub - check lists with equal complexity values, calculate the total radiation value of the connection level tree corresponding to this sub - check list;

[0041] Set the sub - check list with a larger total radiation value as the sub - check list to be preferentially verified among the sub - check lists with equal complexity values.

[0042] Through the above technical solution, generally speaking, the larger the total radiation value of the sub - check list, the greater the connection depth between the updated device and other multi - level different devices, which also means the higher the complexity of this sub - check list. Therefore, it needs to be preferentially verified.

[0043] In a preferred example of the present application, it can be further configured that the total radiation value is calculated using the following formula:

[0044] D = k 1 + k 2 … + k n

[0045] Where D is the total radiation value of the connection level tree, and k n is the radiation value of the final level of the connection level tree, and k 1 、k 2 、kn is the radiation value for different levels of the connection hierarchy tree. The total radiation value of the sub-verification list is the sum of the total radiation values of multiple connection hierarchy trees included in the sub-verification list.

[0046] In a second aspect, based on the above method for verifying the graph-digital model consistency of power grid equipment assets, a system for verifying the graph-digital model consistency of power grid equipment assets provided by this application adopts the following technical solutions:

[0047] A system for verifying the graph-digital model consistency of power grid equipment assets includes:

[0048] An information acquisition module: used to acquire the re-verification list and the current power grid topology map at the corresponding position of the re-verification list;

[0049] A topology map construction module: used to construct the initial power grid topology map corresponding to the re-verification list;

[0050] An overlapping comparison module: used to perform an overlapping comparison between the current power grid topology map and the initial power grid topology map, and generate multiple difference units and multiple identical units;

[0051] A topology map construction module: used to generate a verification topology map.

[0052] In a third aspect, this application also provides an intelligent terminal. The intelligent terminal includes a processor and a memory. At least one instruction, at least one program, a code set or an instruction set is stored in the memory. The at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to implement the processing of the method for verifying the graph-digital model consistency of power grid equipment assets as described in any one of claims 1 to 7.

[0053] In summary, this application includes the following beneficial technical effects:

[0054] 1. Based on the current power grid topology map, mark the difference units and identical units generated by comparing the current power grid topology map and the initial power grid topology map, and generate a verification topology map, which can highlight the difference units and identical units. Compared with using the re-constructed initial power grid topology map, operators can perform content verification more pertinently, thereby improving the work efficiency of operators in checking the updated content of the power grid;

[0055] 2. The checklist will be re-verified, decomposed into several sub-checklists, and different verification priorities will be set for different sub-checklists according to the magnitude of the complexity values of the sub-checklists, so that the content of this update can be verified in a reasonable processing order. If there is only one operator or a small team for verification, the verification will be carried out according to the verification priority. If there are multiple operators or multiple small teams for verification, the sub-checklists will be handed over to different personnel for verification, so as to carry out a more reasonable verification sorting;

[0056] 3. By further refining the sorting logic of the verification priority (that is, when the complexity values of the sub-checklists are equal, compare the magnitudes of the total radiation values), the possibility of the verification priority sorting being disordered and the system being chaotic due to equal complexity values is reduced, and the stability and fluency of the system running this method are improved.

[0066] The following further elaborates on the present application in conjunction with Att Figure 1 - Att Figure 5 for a more detailed description of the present application.

[0067] An embodiment of the present application discloses a method, a system, and an intelligent terminal for verifying the consistency of the graph, data, and model of power grid equipment assets. The execution subject of this method can be a system for verifying the consistency of the graph, data, and model of power grid equipment assets, and the above intelligent terminal can be used to carry the system for verifying the consistency of the graph, data, and model of power grid equipment assets and apply the method for verifying the consistency of the graph, data, and model of power grid equipment assets.

[0068] Refer to the attached Figure 1 As shown, a method for verifying the consistency of the graph, data, and model of power grid equipment assets includes:

[0069] S101. Obtain a re-verification list and the current power grid topology map of the area corresponding to the re-verification list.

[0070] In implementation, the re-verification list includes the specific content of this update, such as the specific equipment updated, the specific location of the equipment, the substation area to which the equipment belongs, the changes in the connection relationship of the updated equipment, and the changes in the operating parameters, etc.

[0071] The current power grid topology map of the area corresponding to the re-verification list refers to the basic layout structure diagram currently in operation, which is composed of power grid nodes (such as power plants, substations, power consumption loads, etc.) and the transmission lines and power equipment connected thereto. The information included in the current power grid topology map also includes the connection relationships, port types, names, and types of various resources. Grid operation and maintenance personnel can perform simulation work such as power flow calculation, fault diagnosis, and dynamic simulation by monitoring the current power grid topology map in the background, which helps to monitor and analyze the operation state of the power grid and improve the safety and reliability of the power grid operation.

[0072] S102. Based on the re-verification list, construct an initial power grid topology map corresponding to the re-verification list.

[0073] In implementation, based on the content updated this time and the most basic structural framework of the power grid system, an initial power grid topology map corresponding to the re-verification list is generated (in relevant patent documents and the prior art, there are specific elaborations, and this content is not the specific object of explanation in this implementation, so it will not be elaborated here).

[0074] The re-constructed initial power grid topology map corresponding to the re-verification list can be based on the content updated this time and the most basic structural framework of the power grid system, or can be constructed according to the basic units and composition logic of the current power grid topology map.

[0075] S103. Overlap and compare the current power grid topology map and the initial power grid topology map to generate a plurality of difference units and a plurality of identical units.

[0076] In implementation, the current power grid topology map and the initial power grid topology map are compared by overlapping. Here, it can be understood that the current power grid topology map and the initial power grid topology map are placed on the same plane, and the veins and lines of the two maps are appropriately scaled and rearranged without affecting the connection relationship, so that the power grid topology map and the initial power grid topology map have a certain degree of coincidence, so as to further discover the obvious differences between the two, and thus multiple difference units (contents with obvious differences) and multiple identical units (contents without obvious differences) can be visually generated.

[0077] S104. Taking the current power grid topology map as the basis, mark multiple difference units and multiple identical units to generate a verification topology map.

[0078] In implementation, multiple difference units and multiple identical units are marked on a template based on the current power grid topology map. Here, it can be understood that the current power grid topology map is printed down, and based on this as the basis, the difference units and identical units are marked to form a verification topology map.

[0079] The operator synchronizes the verification topology map to the mobile terminal (intelligent terminals such as mobile workstations and laptops), and uses the verification topology map to verify the content of this update. The difference units and identical units can be highlighted. Compared with using the re-constructed initial power grid topology map, the operator can perform verification more pertinently, thus improving the work efficiency of the operator in checking the updated content of the power grid.

[0080] Refer to the appendix Figure 2 As shown, after generating the verification topology map, the following processing steps are also included:

[0081] S201. After completing the verification according to the verification topology map, fuse the verification result and the verification topology map to form a topology map to be verified.

[0082] In implementation, after the operator completes the verification through the verification topology map, the verification result is input into the mobile terminal through the mobile terminal, and the system cooperates to complete the fusion of the verification result and the verification topology map to form a topology map to be verified, that is, the power grid topology map to be reviewed by the back-end staff. According to the review result of the topology map to be verified by the back-end, it is decided whether to conduct a second review or other corresponding adjustments.

[0083] S202. Send a review request for the topology map to be verified to the power grid back-end.

[0084] In implementation, the staff of the power grid back-end reviews the topology map to be verified to judge whether the current verification result is compatible with the current power grid topology map, whether there is a disorder in the connection relationship of the content of this update, etc.

[0085] S203. If the review result of the review request is passed, upload the verification result to the current power grid topology diagram and update the current power grid topology diagram.

[0086] In implementation, since the verification topology diagram is generated based on the current power grid topology diagram, the to-be-verified topology diagram and the current power grid topology diagram have a higher degree of coincidence, the passing rate of the review is higher, and the possibility of operators performing secondary verification is reduced.

[0087] After the review request of the to-be-verified topology diagram is passed, directly upload the current verification result to the current power grid topology diagram, update the current power grid topology diagram, and thus complete this verification.

[0088] Refer to Appendix Figure 3 and Appendix Figure 6 As shown, after generating multiple difference units and multiple identical units, the following processing steps are further included:

[0089] S301. According to the connection relationship of the verification content, establish multiple connection level trees of the verification content.

[0090] In implementation, the "connection relationship" referred to here refers to the connection relationship between the current power grid update contents, which can be the connection between a certain device and other devices (such as signal reception and transmission). For example, the connection relationship between an intelligent feeder terminal (which can be used to control the closing and opening of the pole-mounted circuit breaker) and the pole-mounted circuit breaker. Based on this connection relationship, establish the connection level tree of this connection relationship. For a simplified structure schematic diagram of the level tree, refer to Appendix Figure 6 .

[0091] Appendix Figure 6 The connection level tree shown in Appendix includes n levels, the first level, the second level... the nth level. Suppose the intelligent feeder terminal is at the first level, then the pole-mounted circuit breaker is at the second level, and so on.

[0092] S302. Based on the multiple connection level trees, generate multiple sub-verification lists, and each sub-verification list includes multiple difference units and multiple identical units.

[0093] In implementation, the sub-verification list can include multiple difference units and multiple identical units. Among them, each difference unit corresponds to a connection level tree, that is to say, each sub-verification list can include multiple connection level trees.

[0094] S303. Based on the multiple difference units included in the sub-verification list, calculate the complexity value of each sub-verification list.

[0095] The complexity value refers to the degree of complexity of the device connection relationship. The larger the value of the complexity value, the higher the degree of complexity, indicating that the scope of the power grid update content involved in this time is larger and the need for pre-check is greater.

[0096] In implementation, mainly calculate and compare the complexity values of the differential units. First, calculate the complexity value of the connection hierarchy tree corresponding to each differential unit, and then accumulate the complexity values of each connection hierarchy tree to obtain the complexity value of the sub-check list (without considering duplicate units).

[0097] S304. Set different check priorities for each sub-check list based on the numerical size of the complexity values of multiple sub-check lists.

[0098] In implementation, the sub-check list with a larger complexity value can be set to a higher priority, that is, preferentially check the sub-check list with a larger complexity value; set the sub-check list with a smaller complexity value to a lower priority.

[0099] Refer to Appendix Figure 4 and Appendix Figure 6 As shown, calculating the complexity value of each sub-check list includes the following processing steps:

[0100] S401. Set different complexity bases for different levels of the connection hierarchy tree.

[0101] In implementation, there are certain differences in the importance of power equipment at different levels of the connection hierarchy tree. For example, the intelligent feeder terminal can control the opening and closing of the pole-mounted circuit breaker. The intelligent feeder terminal itself is at a relatively important level, while the backup battery used to provide backup energy for the intelligent feeder terminal, although there is a connection relationship between the backup battery and the intelligent feeder terminal, the backup battery is not absolutely important. Therefore, the backup battery is at a relatively lower level of the connection hierarchy tree (which level a specific device is at in the connection hierarchy tree can be set in advance, or the relative connection hierarchy span between devices can be set).

[0102] Therefore, different complexity bases need to be set for devices at different levels of the connection hierarchy tree, which means that the importance of devices at different levels of the connection hierarchy tree is different. For example, for the first level, the complexity base is set to 5a, for the second level, the complexity base is set to 4a, and so on. Of course, the difference in complexity bases between adjacent levels is not strictly an arithmetic progression and can be set and flexibly adjusted according to the actual situation.

[0103] The importance of different levels of the connection hierarchy tree is reflected in the coefficient in front of a in the complexity base, that is, x, y, z, which will be specifically elaborated later.

[0104] S402. Calculate the complexity value of each sub-check list based on the complex cardinality and the radiation values of each level of the connection level tree.

[0105] In implementation, the radiation value refers to the number of basic units of the connection level tree or a certain level on the connection level tree. See the following examples for details. For example, Figure 6 in the attachment, each rectangle represents a basic unit (i.e., a device). There is one basic unit in the first level. Then, the radiation quantity of the first level is 1xa; there are 2 basic units in the second level. Then, the radiation value of the second level is 2ya; there are 5 basic units in the nth level. Then, the radiation value of the nth level is 5za. Here, the nth level is assumed to be the last level of this connection level tree. The complexity value of this connection level tree is 1xa + 2ya + … + 5za = (1x + 2y + 5z)a. Finally, accumulate the complexity values of the connection level trees of this sub-check list to obtain the complexity value of this sub-check list.

[0106] Refer to the attachment Figure 6 As shown, the complexity value of the sub-check list is calculated using the following formula:

[0107] K = k 1 xa + k 2 ya + … + k n za

[0108] where K is the complexity value of the sub-check list, and k 1 、k 2 、k n are the radiation values of different levels of the connection level tree, xa, ya, za are the complexity bases of different levels of the connection level tree, x, y, z are all positive integers, x > y > z, and the complexity value of the sub-check list is the sum of the complexity values of the connection level trees corresponding to the different units included in the sub-check list.

[0109] The radiation quantity of the first level is 1xa, the radiation value of the second level is 2ya, and the radiation value of the nth level is 5za. The complexity value of this connection level tree is 1xa + 2ya + … + 5za = (1x + 2y + 5z)a. Finally, accumulate the complexity values of the connection level trees of this sub-check list to obtain the complexity value of this sub-check list.

[0110] Refer to the attachment Figure 5 and the attachment Figure 6 As shown, based on the numerical magnitudes of the complexity values of multiple sub-check lists, set different check priorities for each sub-check list, including the following processing steps:

[0111] S501. If there are sub-check lists with equal complexity values, calculate the total radiation value of the connection level tree corresponding to this sub-check list.

[0112] In implementation, as the power grid system is continuously updated and expanded, there may be complex sub-verification lists with equal values. At this time, the setting logic of the verification priority is further improved, that is, according to the numerical size of the radiation total value of the sub-verification list corresponding to the connection hierarchy tree, the verification priority is determined.

[0113] S502. Set the sub-verification list with a larger radiation total value as the sub-verification list to be preferentially verified among the sub-verification lists with equal complex values.

[0114] In implementation, the larger the radiation total value of the sub-verification list, the greater the connection depth between the updated equipment and different equipment at other levels, which also means the higher the complexity of the sub-verification list. Therefore, it needs to be verified preferentially.

[0115] The radiation total value is calculated using the following formula:

[0116] D = k 1 + k 2 … + k n

[0117] Where D is the radiation total value of the connection hierarchy tree, and k n is the radiation value of the final level of the connection hierarchy tree, and k 1 , k 2 , k n are the radiation values of different levels of the connection hierarchy tree. The radiation total value of the sub-verification list is the sum of the radiation total values of multiple connection hierarchy trees included in the sub-verification list.
