This solution needs to restore the mapping of a single object in digital space based on the actual situation on site, which requires manual data collection and mapping, is time-consuming and labor-intensive, and lacks linkage between devices.

Based on the message queue, it completes message conversion (conversion, enrichment, filtering), message routing (synchronous / asynchronous, publish / subscribe, content-based routing, branching and aggregation) and other functions to ensure the accuracy and timeliness of data integration.

[0035] The backend application adopts microservice architecture design, and the service governance and security management functions are uniformly provided by the cloud platform. The API gateway is the only entrance for external service calls in the microservice system. All user ends and consumer ends access microservices through a unified gateway. Service governance and security management are uniformly provided by the cloud platform, following the principle of cloud platform component priority to ensure the stability and safe operation of the service.

[0036] (4) Business application layer The front-end presentation layer uses the front-end framework and combines the front-end general components to build application pages. It provides distribution network panoramic monitoring, fault alarm monitoring, and user panoramic monitoring application pages. Based on digital twins, it realizes the monitoring of basic data and real-time data such as power protection venues, substations, transmission lines, distribution equipment, monitoring devices, security resources, fault alarms, risk hazards, patrol repair tasks, weather scale, geographical distribution, etc., and uses statistical charts, detailed tables, and three-dimensional simulation applications to link up for panoramic monitoring and display, timely discover abnormalities, and facilitate all-round grasp of the latest developments in the low-voltage side power supply path tracing of power protection objects. At the same time, it carries out the release and monitoring of various types of auxiliary information such as global meteorological monitoring, power equipment life cycle management, three-dimensional visualization of fault alarms, and alarm history activity dashboards.

[0037] Specifically, a method for tracing the power supply path of an important place based on digital twins in this embodiment is as follows: Figure 1 As shown, the following steps are included: S1: Establish corresponding two-dimensional digital twin scenes and three-dimensional digital twin scenes according to the actual regional scene classification.

[0038] In this embodiment, the two-dimensional digital twin scene is a two-dimensional area scene.

[0039] The two-dimensional regional scene includes the relative positions of various places in the region and the corresponding distribution network equipment in each place. That is, on the two-dimensional map of the area where the important places that need power supply are located, the corresponding power supply-related places that need attention (such as conference venues, switchgear, distribution rooms and substations, etc.) are marked and rendered at the corresponding positions on the map. The relative position relationship between the various places can be expressed.

[0040] Based on the geographic information system, real-time visual monitoring of key areas can be carried out, and the location, status, key indicators and other information of key areas can be linked and analyzed and marked and displayed, and the real-time situation of key areas can be comprehensively monitored. It ensures that the line is processed according to different voltage levels and classifications during the actual operation process.

[0041] In this embodiment, the three-dimensional digital scene is a three-dimensional place scene.

[0042] The three-dimensional venue scene includes the spatial location distribution of the corresponding distribution network equipment in each venue. The venues include switch stations, distribution rooms, venues, and box transformers. That is, the three-dimensional venue is constructed in the corresponding venue. For example, for the distribution room, the venue is constructed according to the actual distribution room location, and the corresponding equipment cabinets and line layouts are arranged at the corresponding positions, so as to complete the three-dimensional digital twin of the distribution room scene.

[0043] Model the supporting distribution substations of the power supply protection site, including the building structure, primary equipment, key secondary equipment, and auxiliary control equipment. The modeling level granularity reaches the L3 level, and the DTID label production is completed. The relevant tower lines and station buildings are modeled and data matched for the power supply path of the venue, and the two-dimensional and three-dimensional linkage matching of the power supply path is completed. The protection level and voltage classification information of each protection line are displayed, and the chart effect optimization classification of each protection line is realized. The relevant chart information is displayed according to the different protection levels of the station end, including the basic information of the station end, the chart display of power load, and the effect of the primary wiring diagram.

[0044] The digital twin scenarios are constructed hierarchically from the macro regional scenarios and specific location scenarios respectively. This can monitor the power supply relationship of each power supply path in the region at a macro level, and can also carry out targeted information supervision of the distribution network equipment in each scenario.

[0045] S2: Obtain the device information including the IP address uploaded by each distribution network device from the control center of the corresponding area; allocate the distribution network device to the corresponding spatial position in the two-dimensional digital twin scene and the three-dimensional digital twin scene according to the monitoring device information.

[0046] S201: Obtain device information uploaded by the distribution network device from the regional control center.

[0047] The monitoring device information includes IP address, type, model, number and indicator parameters of the corresponding type (such as the switching state of a switch, the current value of an ammeter, etc.).

[0048] The system supports viewing distribution substations, distribution network lines, distribution network equipment, voltage levels, feeders, substations, real-time telemetering and other basic information. It supports monitoring the power supply topology of the distribution network based on the primary single-line diagram and displays the energized status of the distribution equipment. It integrates the operating status of the user-side switch station, internal distribution room, internal box-type transformer electrical equipment, temporary power equipment at the venue, etc., including online monitoring data.

[0049] S202: Allocate the network distribution device to a corresponding place in the two-dimensional digital scene according to the IP address in the device information of the network distribution device.

[0050] Each site corresponds to a different IP address, and the site to which the corresponding data belongs is determined based on the IP address uploaded by the distribution network device.

[0051] S203: For the network distribution devices in each location, match the device type and number of the device information with the network distribution devices in the three-dimensional digital scene, and match the device information to the corresponding spatial position.

[0052] Each device has its own unique code. According to the type of distribution network equipment and its number, the location of the field survey or the on-site image information obtained by the camera, the corresponding device data can be matched to the corresponding actual spatial location.

[0053] S3: Connect each distribution network device according to the existing topology diagram to form a preliminary power supply path, control the distribution network devices to send marking instructions to the upstream distribution network devices respectively, and the distribution network devices send the marking feedback to the control center to optimize and correct the preliminary power supply path to form several equipment power supply paths.

[0054] S301: Obtain the corresponding distribution network topology map in the area from the control center of the area, connect the distribution network devices in the digital scene according to the distribution network topology map, and obtain a preliminary power supply path.

[0055] The power topology map of the corresponding area is generally stored in the control center of the area. According to the stored power topology map, each place in the constructed two-dimensional digital scene is taken as a node and connected to form several preliminary power supply paths.

[0056] Furthermore, for each venue, each power supply path is refined according to the power topology diagram, and each device in the venue is connected to improve the preliminary power supply path.

[0057] S302: Acquire each terminal distribution network device in the preliminary power supply path, control each distribution network device to send a marking instruction to the upstream distribution network device respectively, and the distribution network device sends a marking feedback to the control center after receiving the marking instruction.

[0058] The marking instruction is a tag whose name includes the unique number of the terminal distribution network device; the initial value of the marking instruction is 0; in this embodiment, the expression of the instruction marking is: flag(X), where X is the unique number of the terminal distribution network device.

[0059] After receiving the instruction tag sent by the downstream distribution network device, the distribution network device adds one to the value of the instruction tag to obtain the corresponding tag feedback; the tag feedback is a tag whose name includes the unique number of the corresponding terminal distribution network device and the unique code of the distribution network device that sends the instruction tag.

[0060] The expression of flag feedback is flag(X_Y), where Y is the unique code of the distribution network device that sends the command tag.

[0061] That is, flag(X_Y) = flag(X) + 1 The distribution network equipment collects all the tag feedback and sends it to the control center.

[0062] like Figure 2 As shown, the instruction tag is passed as follows: 1) The terminal distribution network device sends a command tag with an initial value of 0 to the upstream distribution network device.

[0063] 2) For the distribution network device that receives the command tag, the command tag is increased by one to form a tag feedback, and the command tag with the value increased by one is passed to the remaining distribution network devices that have not sent the command tags to it and are connected to it.

[0064] 3) The command mark is passed cyclically until there is no object to which the command mark can be passed in all the distribution network devices.

[0065] The connection relationship between distribution network devices is determined through the transmission of information flow, which is used to improve the topology diagram and ensure the reliability of the power supply path.

[0066] S303: The control center collects tag feedback from each distribution network device, and forms a topological connection relationship between distribution networks according to the content of the tag feedback.

[0067] The control center of the region will be classified according to the expression of the marked feedback and arranged from large to small values; and several groups of topological connection relationships will be obtained.

[0068] The tag feedbacks with the unique code X of the same terminal device are grouped into one category; for the distribution network devices with the same value in the same category, the connection object is determined according to the distribution network device Y that sends the instruction tag, thereby obtaining the corresponding topological connection relationship.

[0069] S304: Compare the topological connection relationship of the marked feedback with the distribution network topology diagram, optimize and supplement the preliminary power supply path, and form a plurality of equipment power supply paths.

[0070] Traverse all topological connection relationships to determine whether the same topological connection relationship exists in the preliminary power supply path; if so, remove the corresponding topological connection relationship; otherwise, proceed to the next step of new conflict judgment.

[0071] Determine whether the topological connection relationship conflicts with the existing preliminary power supply path. If so, remove the corresponding topological connection relationship; otherwise, form a device power supply path according to the topological connection relationship.

[0072] S4: When the distribution network equipment is abnormal, trace the power supply path where the distribution network equipment is located to determine the fault path and faulty equipment.

[0073] S401: Collect and obtain device information uploaded by each distribution network device in real time, compare the indicator parameters in the device information with the corresponding threshold value, and determine whether the distribution network device is abnormal.

[0074] S402: When the distribution network equipment is abnormal, trace the source upward according to the equipment power supply path, and determine the faulty power supply node based on the distribution network equipment status of each power supply node in the equipment power supply path.

[0075] like Figure 3 As shown in the figure, the process of tracing back to the source according to the power supply path of the device is as follows: 1) If there is only one abnormal power supply path in the same time period, the most upstream power supply node with the abnormal device in the power supply path is determined as the faulty power supply node.

[0076] 2) If there is more than one abnormal power supply path in the same time period, it is determined whether the abnormal power supply paths have the same power supply node.

[0077] If not, the most upstream power supply node with the abnormal device in the power supply path is determined as the faulty power supply node.

[0078] If it exists, the power supply node with the same path is extracted, and the device information of the abnormal device in the corresponding power supply node is fed back.

[0079] S403: Determine the impact scope of the fault according to the power supply paths of all devices associated with the faulty power supply node; locate the spatial position of the faulty device and perform power protection operations.

[0080] Determine whether the abnormal devices of the same power supply node in each power supply path are the same. If so, extract the same abnormal devices and determine them as faulty devices; otherwise, check each abnormal device separately and determine the abnormal device most upstream in the power supply path as the faulty device.

[0081] Each power supply path can be traced back to its source at the same time, and the fault location can be quickly determined through the common fault node. The determination is more intuitive, which is conducive to the determination of emergency faults at important moments and improves the scheduling speed of subsequent maintenance.

[0082] After the faulty device is identified, all downstream power supply paths associated with the faulty device are marked as the fault impact range.

[0083] The faulty power supply nodes of the fault path and the fault impact range are displayed in the two-dimensional digital scene; the location of the faulty equipment is displayed in the three-dimensional digital scene.

[0084] Visually display the impact range and specific location of faulty equipment caused by equipment failure, providing clear and intuitive guidance for logistics power supply guarantee.

[0085] The scheme of this embodiment constructs digital twin scenarios in a hierarchical manner from macro regional scenarios and specific venue scenarios, respectively. It can supervise the power supply relationship of each power supply path in the region at a macro level, and can also conduct targeted information supervision on the distribution network equipment in each scenario. According to the power topology and the signal flow relationship between the equipment, a complete power supply path is constructed, and the power supply path is traced to the source when the equipment fails, and the impact range is determined. The tracing is fast and accurate. For each power supply path, the source is traced upward at the same time, and the fault location is quickly determined through the common fault node. The determination is more intuitive, which is conducive to the determination of emergency faults at important moments and improves the scheduling speed of subsequent maintenance. The impact range and specific location of the faulty equipment caused by the equipment failure are displayed visually, providing clear and intuitive guidance for logistics power supply guarantee.
