The present invention relates to the field of power supply path tracing, and in particular to a method for tracing power supply paths in important locations based on digital twins.
In view of the power maintenance command work of major events, the traditional venue power supply path traceability guarantee dimension coverage is not insufficient, the equipment status monitoring range is not comprehensive enough, the control implementation and supervision of power maintenance patrol watch and rush repair task as well as the effectiveness of on-site penetration command need to be improved.
The conventional twin construction of venues mostly employs an agile development model with actual on-site demands as a core, while the on-site modeling demand is often achieved by collecting manually and with the help of equipment, and the details are judged by human eyes and experience values. When the mapping of a single object in a digital space is restored according to the actual situation on the spot, there is a lack of linkage display between equipment; and if some equipment encounters abnormalities, it is difficult to determine the nodes causing the failure and the fault impact scope by tracing the power supply paths corresponding to the abnormal equipment. For example, a “Digital Twinning System for Power Plant” disclosed in the Chinese patent document with Publication No. of CN114926603A includes: a three-dimensional scenario layer, used for performing forward three-dimensional design and reverse three-dimensional design on a power plant to build a digital power plant; a digital twin implementation layer, used for performing three-dimensional element extraction on the digital power plant, establishing a mapping relationship between three-dimensional elements and codes of a power plant identification system, configuring a logical relationship between the three-dimensional elements with the established mapping relationship, and coupling the three-dimensional elements with multi-source data of the power plant according to the mapping relationship and the logical relationship to build a digital twin power plant; and a display layer, where the display layer is interactively connected with the digital twin implementation layer and is used to render and display the digital twin power plant. This solution needs to restore the mapping of a single object in a digital space according to the actual situation on the spot, which requires manual data collection and mapping, thus being time-consuming and laborious, and lacking linkage between equipment.
The present invention mainly solves the problem that it is time-consuming and laborious in the prior art due to the fact of requiring manual data collection and mapping in the case where the mapping of a single object in a digital space needs to be restored according to the actual situation on the spot. Provided is a method for tracing power supply paths in important locations based on digital twins, which hierarchically establishes digital twin scenarios, constructs a complete power supply path according to a signal flow relationship between power topology and equipment, and conducts power supply path tracing in the event of equipment failure to determine a scope of influence, thus being fast and accurate in tracing.

A method for tracing power supply paths in important locations based on digital twins in this embodiment can be applied to power maintenance locations of several conference venues such as integrated conference theme pavilions, conference exhibition halls and report halls. Microservice-oriented architecture design is employed. Based on the infrastructure of an integrated cloud platform, new business applications are added using the IaaS and PaaS capability components of the integrated cloud platform, and cloud deployment is carried out by means of node virtualization. The application scenarios and capabilities of the components are as follow:
An infrastructure layer provides general computing, memory, and network services. The computing service provides new business applications added based on computing environments such as virtual machines. The memory service supports data storage methods such as relational database storage, object storage, and file storage. A system bus provides a message queue. The network service provides dedicated network VPC, load balancing, virtual firewall and other capabilities.
User-side power distribution monitoring and analysis applications are based on the integrated scheduling graphics, models and data of a business central console, network configuration, as well as the graphics, models and data for user-side network configuration. Hot spot data is cached in a memory by using a cache database technology, which can greatly reduce the reading pressure on the central console.
In order to improve performance, the service layer internally applies RPC or Restful protocols for mutual invocation, and services are registered and discovered through a unified registration center for effective service management.
A system provides real-time data integration services, graph and model access and verification services in response to a central console, and provides real-time data release services and alarm services externally. Based on a message queue, the functions such as message conversion (conversion, enrichment, filtering), and message routing (synchronous/asynchronous, publish/subscribe, content-based routing, branching and aggregation) are completed to ensure the accuracy and timeliness of data integration.
The back-end application adopts microservice-oriented architecture design. The service governance and security management functions are provided by a cloud platform in a unified manner. API gateway is the only entry point for external service calls of a microservice system, and all clients and consumers access microservices through the unified gateway. Service governance and security management are provided by the cloud platform in a unified manner, following the principle of giving priority to components of the cloud platform, so as to ensure the stable and safe operation of services.
A front-end presentation layer adopts a front-end framework, combined with front-end generic components, so as to build application pages. The application pages for network distribution panoramic monitoring, fault alarm monitoring, and user panoramic monitoring are provided. Based on digital twins, the monitoring of basic data and real-time data such as power maintenance venues, substations, power transmission lines, power distribution equipment, monitoring devices, security resources, fault alarms, risk hidden dangers, inspection and repair tasks, weather scale, and geographical distribution is realized, the panoramic monitoring display is carried out by using the linkage of statistical chart, detailed lists, and three-dimensional simulation applications, and thus abnormalities are found in time, which facilitates a comprehensive understanding of the latest developments in tracing of low-voltage power supply paths of current holding objects.

That is, on the two-dimensional map of a regional scope where the important locations that require power maintenance are located, the corresponding power supply related locations (such as conference venues, switching stations, power distribution rooms, and substations) that need attention are displayed at the corresponding positions on the map by marking and rendering. The relative positional relationships between the locations can be expressed.
Based on a geographic information system, real-time visual monitoring is performed on key areas, the locations, statuses, key indexes and other information of the key areas can be analyzed in a manner of linkage, labeled and displayed, and the real-time situation of the key areas can be comprehensively monitored.
