[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] The global power grid maintenance method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, in one embodiment, a computer device is provided, which may be a server, and its internal structure diagram may be as follows. Figure 1 As shown, this computer device includes a processor, memory, input / output (I / O) interfaces, and a communication interface. The processor, memory, and I / O interfaces are connected via a system bus, and the communication interface is also connected to the system bus via the I / O interfaces. The processor provides computational and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system, computer programs, and a database. The internal memory provides the environment for the operating system and computer programs stored in the non-volatile storage media. The database stores operating status, abnormal substations, location information, a global power grid fault map, and power grid topology data. The I / O interfaces are used for information exchange between the processor and external devices. The communication interface is used for communication with external terminals via a network connection. When the computer program is executed by the processor, it implements a global power grid maintenance method.

[0055] This embodiment provides a global power grid maintenance method, device, computer equipment, and storage medium. Based on the operating status of all substations in the global power grid, abnormal substations in the global power grid are identified. Based on the location information of the abnormal substations, a global power grid fault map is constructed. Then, based on the location information of the abnormal substations in the global power grid fault map and the power grid topology, the maintenance sequence of the abnormal substations is determined. Finally, based on the maintenance sequence, the abnormal substations are maintained and processed sequentially.

[0056] In one embodiment, such as Figure 2As shown, a global power grid maintenance method is provided, which can be applied to... Figure 1 Taking the server in the example, the following steps are included:

[0057] S201 determines the abnormal substations in the global power grid based on the operating status of all substations in the global power grid.

[0058] The global power grid can be a power grid composed of substations and transmission and distribution lines of various voltages within the area to be detected.

[0059] Among them, the global substation can be any substation in the global power grid.

[0060] The operating status can characterize whether a substation is operating normally. Specifically, the operating status includes normal status and abnormal status.

[0061] Among them, an abnormal substation can be a substation with an abnormal operating status.

[0062] Optionally, based on the obtained operating status of all substations in the global power grid, it is determined whether the operating status of each substation in the global power grid is abnormal, and substations with abnormal operating status are identified as abnormal substations.

[0063] Furthermore, there are many ways to obtain the operating status of all substations in the global power grid, and this embodiment does not limit this method. For example, one optional implementation method is to obtain the operating status of all substations in the global power grid based on the Petri Net process model of the global substations. Optionally, alarm logs in the real-time log stream of each substation in the global power grid are obtained, the Petri Net process model is invoked, and a target storage link is determined from the candidate storage links based on the alarm logs. The operating status of the equipment corresponding to the alarm log is then determined from the target storage link as the operating status of that substation. The operating status of each substation determined by the Petri Net process model is received, and the operating status of all substations is taken as the operating status of all substations in the global power grid. The candidate storage links are generated based on historical alarm logs in the real-time log stream of the substations. Specifically, the Petri Net process model is invoked to determine the currently held token corresponding to the alarm log. Based on the matching relationship between the currently held token and the candidate held token corresponding to the initial state library in the candidate library link, the target library link is determined from the candidate library link. The candidate held token corresponding to the initial state library in the target library link is migrated to the subsequent library of the target library link. Based on the candidate held token migrated to the subsequent library, the target library is determined from each subsequent library according to the matching relationship between the alarm log and the historical alarm logs corresponding to each subsequent library of the initial state library in the target library link. Finally, the device operating status corresponding to the target library is taken as the device operating status corresponding to the alarm log.

[0064] Another alternative implementation is to maintain a local operating status table, which records the current operating status of all substations in the global substation network. Each substation in the global substation network updates the operating status table based on its real-time operating status. Optionally, the operating status of all substations in the global power grid can be found based on the operating status table.

[0065] Another alternative implementation is that the server sends an operation status acquisition instruction to each substation in the global power grid. After receiving the acquisition instruction, the substation in the global power grid will obtain the current operation status of the substation from the operation log maintained locally by the substation, and send the current operation status of the substation to the server. Based on the received operation status of each substation, the server determines the operation status of the global substation in the global power grid.

[0066] In addition, this embodiment can also use the active_stations set, which is based on the obtained abnormal substations in abnormal operation, to store the substations in abnormal operation.

[0067] S202 constructs a global power grid fault map based on the location information of abnormal substations.

[0068] The location information can be the location of the abnormal substation within the area to be detected.

[0069] The global power grid fault map can be a regional map that records the location information of each abnormal substation within the area to be detected. Optionally, the global power grid fault map records the location information of the abnormal substations and the power grid topology.

[0070] The power grid topology can be a topological relationship consisting of the locational relationships between various abnormal substations within the detection area. Optionally, this power grid topology can be obtained based on a City Information Modeling (CIM) database. This CIM database is in text format; for ease of data processing, it can also be migrated to a neo4j graph database.

[0071] Optionally, for each abnormal substation, its location information is obtained from its attribute information. Based on this location information, the power grid topology between abnormal substations can be determined using a pre-set network construction model. For example, the location information of each abnormal substation can be input into the network construction model, which will then generate the power grid topology between all abnormal substations. Alternatively, the power grid topology between abnormal substations can be obtained from a pre-set urban information model database, which contains the location information of all abnormal substations within the detection area and their corresponding power grid topology. Then, a power grid area map corresponding to the detection area is obtained. Based on the location information of each abnormal substation, all abnormal substations are added to their corresponding locations on the power grid area map. Finally, the power grid topology between all abnormal substations is mapped onto the power grid area map, forming a global power grid fault map.

[0072] Based on the location information of abnormal substations and the power grid topology in the global power grid fault map, S203 determines the maintenance sequence of abnormal substations and performs maintenance on the abnormal substations in sequence.

[0073] Optionally, based on the acquired global power grid fault map, the location information and power grid topology of abnormal substations are parsed from the global power grid fault map, and an abnormal substation is randomly selected as the starting substation. Based on this starting substation, as well as the location information and power grid topology of abnormal substations in the global power grid fault map, a candidate maintenance route corresponding to the starting substation is obtained by traversing all abnormal substations in the global power grid fault map through a pre-set route generation model. Then, the maintenance route with the shortest distance is selected from these candidate maintenance routes as the target maintenance route, and the order of abnormal substations in the target maintenance route is sent to the terminal equipment of the maintenance personnel as the maintenance order of abnormal substations, so that the maintenance personnel can perform maintenance on the abnormal substations in sequence according to the maintenance order.

[0074] The aforementioned global power grid maintenance method identifies abnormal substations in the global power grid based on their operational status. It then constructs a global power grid fault map based on the location information of these abnormal substations. Finally, it determines the maintenance sequence for these abnormal substations based on their location information and the power grid topology, and performs maintenance on them sequentially. This approach obtains the operational status of all substations, selects abnormal substations, and constructs a global power grid fault map based on their location information, making the fault map more accurate and comprehensive. Furthermore, determining the maintenance sequence based on the location information and power grid topology allows maintenance personnel to perform maintenance according to the established order, further improving the comprehensiveness, timeliness, and efficiency of abnormal substation maintenance.

[0075] It should be noted that if an abnormal substation update event is detected in the global power grid, the global power grid fault map is updated based on the location information of the abnormal substation to be updated. The abnormal substation update event can be an event requiring the addition or deletion of abnormal substations in the global power grid fault map. Optionally, if an abnormal substation update event is detected, the event is parsed. If the parsing result indicates the addition of an abnormal substation to the global power grid fault map, the location information of the abnormal substation to be added is obtained from the update event. Based on this location information, the power grid topology relationship between the abnormal substation to be added and existing abnormal substations in the global power grid fault map is determined. According to the location information of each abnormal substation to be added, all abnormal substations to be added are added to their corresponding positions in the global power grid fault map. Finally, the abnormal substations to be added are compared with existing abnormal substations. The power grid topology is mapped to the global power grid fault map, thus enabling the updating of the global power grid fault map. If the parsing result is the deletion of an abnormal substation in the global power grid fault map, the location information of the abnormal substation to be deleted is obtained from the abnormal substation update event. Based on the location information of the abnormal substation to be deleted, the corresponding power grid topology in the global power grid fault map is determined. Based on the location information of all abnormal substations to be deleted and their corresponding power grid topology, the abnormal substations are deleted from the global power grid fault map, specifically including the deletion of the abnormal substations and their corresponding power grid topology. This achieves the updating of the global power grid fault map. The advantage of this setup is that it allows for real-time updates to the global power grid fault map, enabling automatic adjustments based on the real-time substation operating status. The global power grid fault map displays the latest substation operating status to maintenance personnel, further improving the accuracy, real-time performance, and comprehensiveness of the global power grid fault map.

[0076] Figure 3 This is a flowchart illustrating the process of constructing a global power grid fault map in one embodiment. In this embodiment, the accuracy of the constructed global power grid fault map directly affects whether maintenance personnel can quickly and accurately repair abnormal substations. Therefore, how to construct an accurate global power grid fault map is crucial. This embodiment provides an optional method for constructing a global power grid fault map, including the following steps:

[0077] S301 determines the distance information between different abnormal substations based on the location information of each abnormal substation.

[0078] Among them, distance information can be information representing the shortest distance between two substations.

[0079] Optionally, based on the location of each abnormal substation in the global power grid fault map, the distance between each abnormal substation and other abnormal substations in the global power grid fault map is calculated, and this distance is used as the distance information between different abnormal substations. For example, if the global power grid fault map includes abnormal substation 1, abnormal substation 2, and abnormal substation 3, the shortest distance 13 between abnormal substation 1 and abnormal substation 3, the shortest distance 12 between abnormal substation 1 and abnormal substation 2, and the shortest distance 23 between abnormal substation 2 and abnormal substation 3 are calculated. The shortest distance 13 is the distance information between abnormal substation 1 and abnormal substation 3, the shortest distance 12 is the distance information between abnormal substation 1 and abnormal substation 2, and the shortest distance 23 is the distance information between abnormal substation 2 and abnormal substation 3.

[0080] S302 determines the power grid topology relationship between different abnormal substations based on the distance information between them.

[0081] Optionally, there are various ways to determine the power grid topology relationship between different abnormal substations based on the distance information between them, and this application does not limit this one.

[0082] One possible implementation is to connect the two abnormal substations corresponding to the distance information obtained from the abnormal substations to form a topology connection between the two abnormal substations, and form a power grid topology relationship between different abnormal substations based on the topology connection between each abnormal substation in the global power grid and other abnormal substations in the global power grid.

[0083] Another optional implementation method is to determine a topology linking strategy based on the power grid maintenance method; and to determine the power grid topology relationship between different abnormal substations based on the topology linking strategy and the distance information between different abnormal substations. The power grid maintenance method includes: single-point sequential maintenance and multi-point parallel maintenance. The topology linking strategy can be a strategy that determines the different connection methods between each abnormal substation.

[0084] Optionally, the topology linking strategy for the single-point one-to-one maintenance method can be based on the shortest distance for topology linking; the topology linking strategy for the multi-point parallel maintenance method can be to establish topology links between any two substations.

[0085] Specifically, if the topology linking strategy is the first topology linking strategy corresponding to the single-point-by-one maintenance method, then any one abnormal substation is selected from all abnormal substations as the first substation. The distance information between this first substation and all other abnormal substations without a topology relationship is calculated. The abnormal substation with the shortest distance is selected as the second substation. The first substation and the second substation are connected to form a topology link between the two abnormal substations. At this point, a topology relationship exists between the first substation and the second substation. It is then determined whether there are any substations without a topology link among the abnormal substations. If so, the second substation determined in this operation is selected as the next first substation, and the above operation is repeated. If not, a power grid topology relationship between different abnormal substations is formed based on all obtained topology links. For example, as shown... Figure 4 As shown in the figure, the circles represent abnormal substations, and the lines represent the distance information between two abnormal substations. The global power grid fault map shown in the figure includes abnormal substations 1, 2, and 3. Abnormal substation 1 is designated as the first substation. At this point, there is no topological relationship between abnormal substations 2 and 3 and abnormal substation 1. Therefore, the distance information between abnormal substations 1 and 2, and between 1 and 3, is calculated. Based on the calculation results, the shortest distance 12 between abnormal substations 1 and 2 is the shortest distance information. Therefore, abnormal substation 2 is designated as the second substation, and a [missing information - likely a specific substation name or structure] is formed. The topology between abnormal substation 1 and abnormal substation 2 is established. Abnormal substation 2 is then designated as the first substation. At this point, only abnormal substation 3 does not have a topology relationship. The shortest distance 23 between abnormal substation 2 and abnormal substation 3 is used as the shortest distance between these two substations to form a topology relationship. Finally, abnormal substation 3 is designated as the first substation. At this point, there are no abnormal substations with no topology relationship. Therefore, the power grid topology relationship corresponding to single-point maintenance is the power grid topology relationship formed by the shortest distance 12 between abnormal substation 1 and abnormal substation 2, and the shortest distance 23 between abnormal substation 3 and abnormal substation 2.

[0086] Specifically, if the topology linking strategy is the second topology linking strategy corresponding to multi-point parallel maintenance, then based on the distance information between each pair of abnormal substations, the two abnormal substations corresponding to the distance information are connected to form a topology connection between the two abnormal substations. Based on the topology connection between each abnormal substation in the global power grid fault map and other abnormal substations in the global power grid fault map, the power grid topology relationship between different abnormal substations is formed.

[0087] For example, such as Figure 5As shown in the figure, the circles represent abnormal substations, and the lines represent the distance information between two abnormal substations. The global power grid fault map shown in the figure includes abnormal substation 1, abnormal substation 2, and abnormal substation 3. Among them, the shortest distance 13 is the distance information between abnormal substation 3 and abnormal substation 1, the shortest distance 23 is the distance information between abnormal substation 3 and abnormal substation 2, and the shortest distance 12 is the distance information between abnormal substation 1 and abnormal substation 2. Therefore, the power grid topology corresponding to multi-point parallel maintenance is the power grid topology formed by the shortest distance 12 between abnormal substation 1 and abnormal substation 2, the shortest distance 23 between abnormal substation 3 and abnormal substation 2, and the shortest distance 13 between abnormal substation 3 and abnormal substation 1.

[0088] S303 constructs a global power grid fault map based on the location information of each abnormal substation and the power grid topology relationship between different abnormal substations.

[0089] Optionally, based on the location information of each abnormal substation and the obtained power grid topology relationship between different abnormal substations, all abnormal substations are added to the corresponding locations in the power grid area map according to the location information of each abnormal substation, and then the power grid topology relationship between all abnormal substations is mapped to the power grid area map to form a global power grid fault map containing multiple abnormal substations and power grid topology relationships.

[0090] The aforementioned construction of a global power grid fault map involves determining the distances between different abnormal substations based on their location information, then determining the power grid topology relationships between them, and finally constructing the global power grid fault map based on the location information of each abnormal substation and the power grid topology relationships between them. This embodiment determines the power grid topology relationships based on distance information, making the determined topology relationships more reasonable. Furthermore, the global power grid fault map is constructed based on the determined distance information and power grid topology relationships, resulting in a more comprehensive and accurate global power grid fault map. This further improves the efficiency and accuracy of subsequent maintenance personnel in repairing abnormal substations based on the global power grid fault map.

[0091] Figure 6 This is a flowchart illustrating the process of acquiring and adding fault information in one embodiment. To improve the accuracy and efficiency of maintenance of abnormal substations based on the global power grid fault map, fault information of abnormal substations can be introduced into the global power grid fault map. Therefore, this embodiment provides an optional method for acquiring and adding fault information, including the following steps:

[0092] S601 obtains fault information from abnormal substations.

[0093] Among them, fault information can be information that characterizes the cause, type and status of faults in abnormal substations.

[0094] Optionally, fault information reported by the abnormal substation can be obtained by establishing a communication connection with the abnormal substation. Alternatively, fault information can be obtained from the fault log of each abnormal substation by calling the fault log set locally, and this fault information can be used as the fault information of the abnormal substation.

[0095] S602 adds fault information of abnormal substations to the location information of abnormal substations in the global power grid fault map.

[0096] Optionally, based on the obtained fault information, the location information of the abnormal substation corresponding to the fault information in the global power grid fault map is determined, and the fault information is added to the location information of the abnormal substation.

[0097] In addition, this embodiment can also, based on the acquired fault information, look up the corresponding fault identifier from the fault information identifier table, and add the found fault identifier to the location information of the abnormal substation in the global power grid fault map. Optionally, the fault identifier can be at least one of text or color. The fault information identifier table records the correspondence between each fault information and the fault identifier.

[0098] For example, the fault identifier can be a text description of the fault information displayed on or near the icon of the abnormal substation, or different colors can be used to represent different types of fault information. The identifiers of abnormal substations of different colors can be added to the location information of the abnormal substation, and the fault types corresponding to different colors can be marked in the legend of the global power grid fault map.

[0099] The method described above for obtaining and adding fault information acquires fault information of abnormal substations and adds this information to the location information of the abnormal substations in the global power grid fault map. This embodiment can add the acquired fault information to the location information of abnormal substations in the global power grid fault map, realizing the visualization of abnormal substation fault information. This allows users to directly obtain the fault status of abnormal substations from the global power grid fault map, facilitating subsequent maintenance of abnormal substations and improving the accuracy and comprehensiveness of the global power grid fault map.

[0100] In one embodiment, this embodiment provides an optional method for global power grid maintenance, using the application of this method to a server as an example for illustration. For example... Figure 7 As shown, the method includes the following steps:

[0101] S701 obtains the operating status of the global substation in the global power grid based on the Petri Net process model of the global substation.

[0102] S702 determines abnormal substations in the global power grid based on the operating status of all substations in the global power grid.

[0103] S703 determines the distance information between different abnormal substations based on the location information of each abnormal substation.

[0104] S704 determines the topology linking strategy based on the power grid maintenance method.

[0105] S705 determines the power grid topology relationship between different abnormal substations based on the topology linking strategy and the distance information between different abnormal substations.

[0106] S706 constructs a global power grid fault map based on the location information of each abnormal substation and the power grid topology relationship between different abnormal substations.

[0107] S707 obtains fault information from abnormal substations.

[0108] S708 adds fault information of abnormal substations to the location information of abnormal substations in the global power grid fault map.

[0109] Based on the location information of abnormal substations and the grid topology in the global power grid fault map, S709 determines the maintenance sequence of abnormal substations and performs maintenance on the abnormal substations in sequence.

[0110] If S710 detects an abnormal substation update event in the global power grid, it updates the global power grid fault map based on the location information of the abnormal substation to be updated.

[0111] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
