Description

Technical Field

[0001] This application belongs to the field of power distribution network visualization technology, and specifically relates to a power distribution network visualization display method and a power distribution network visualization display device. Background Technology

[0002] In traditional power distribution network visualization systems, there are two main types of graphical display tools: one is a single-line diagram display, which is usually developed in-house; the other is a geographic map display, which typically uses commercial geographic information systems such as MapInfo, ARCInfo, and Smalllord.

[0003] Single-line diagram tools primarily display the logical relationships of electrical connections, without concern for specific locations, focusing only on topological connections and corresponding measured values ​​and switch open / closed states. Graphs also include trend graphs such as curves and bar charts. Dispatchers use the data displayed on the graphs to understand the operation of the distribution network. Geographic information maps display the geographical location and terrain of equipment, facilitating equipment inspection and understanding the location and direction of pipelines. The main characteristic of these two types of graphic display technologies is that, based on the graphs (single-line diagrams or geographic maps), they simultaneously display data information of power equipment, such as: active power, reactive power, current, voltage, phase angle, and the open / closed states of switches and disconnectors.

[0004] These two types of diagrams can reflect the actual operation of the power distribution network in a realistic and intuitive way, but they do not perform further analysis. The dispatcher must manually search and retrieve whichever screen or data they need. The disadvantages are: manual selection is required, which is time-consuming. In emergencies, the dispatcher may not be able to keep up. Important information cannot be proactively provided to the dispatcher. There is no analysis function, and the data format is relatively simple.

[0005] Therefore, it is desirable to have a technical solution to overcome or at least mitigate one of the aforementioned defects of the prior art. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0045] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Figure 1 This is a flowchart illustrating a distribution network visualization method provided in one embodiment of this application.

[0047] like Figure 1 The methods for visualizing the power distribution network shown include:

[0048] Step 1: Obtain the main and distribution network connectivity model;

[0049] Step 2: Obtain the 10KV distribution network topology connection diagram;

[0050] Step 3: Obtain comprehensive information;

[0051] Step 4: Generate a distribution network visualization diagram based on the main distribution network connectivity model, the 10KV distribution network topology connection diagram, and comprehensive information.

[0052] Step 5: Obtain viewpoint location information;

[0053] Step 6: Based on the viewpoint location information, generate a visualization map based on the power distribution network visualization map.

[0054] The distribution network visualization method of this application integrates comprehensive information, the main distribution network connectivity model, and the 10KV distribution network topology connection diagram to generate a distribution network visualization diagram, which solves the problems of manual selection and time consumption in the prior art.

[0055] In this embodiment, step 1: obtaining the main and distribution network connectivity model includes:

[0056] Step 11: Obtain the main network model, the main network model information including the main network outgoing switch information;

[0057] Step 12: Obtain the 10kV feeder distribution network model;

[0058] Step 13: Based on the main grid outgoing switch information, obtain the feeder and end feeder segment information associated with the 10kV feeder distribution network model;

[0059] Step 14: Modify the information of the end feeder segment to connect the main grid model and the 10kV feeder distribution network model.

[0060] In this embodiment, the main network model is obtained through EMS; the 10kV feeder distribution network model is obtained through a GIS system.

[0061] In this embodiment, the comprehensive information includes equipment certification information, user information, and material information.

[0062] User information includes things like the community's power distribution information, such as transformer supply status.

[0063] Material usage information, such as power outage data and power-on data.

[0064] In this embodiment, generating a distribution network visualization diagram based on the main distribution network connectivity model, the 10KV distribution network topology connection diagram, and comprehensive information includes:

[0065] The main distribution network connectivity model, the 10KV distribution network topology connection diagram, and comprehensive information are integrated into merged information.

[0066] A power distribution network visualization map is generated based on the integrated information.

[0067] Specifically, data fusion is based on the CIM (Common Information Model). Initial data extraction involves exporting all data from the database tables, while incremental data is synchronized to the Kafka message queue in real-time and near real-time via Oracle OGG. Kafka is a high-efficiency message queue implementation. By subscribing to Kafka message queues, downstream systems can obtain real-time data changes from the online Oracle system, providing a data foundation for business systems.

[0068] Step 1: First, manage the integration of GIS map and model file information with equipment-related parameters maintained in PMS to achieve "map-data consistency".

[0069] Step 2: The marketing system can obtain the relationship between users and distribution transformers, thereby realizing the association between users and circuits, that is, realizing the splicing with the feeder model to form an integrated power distribution network model.

[0070] Step 3: Integrate power outage and measurement data. Real-time collection of power outage and measurement data is completed through the WebService interface. The analysis of the entire line, branch lines, and distribution transformers is completed through topology. Real-time power outage information is displayed by combining the geographic information system and the power consumption model of the distribution network. The extraction of measurement data is completed through ETL technology. Each node of the measurement data is calculated to form the distribution network anomaly information of T-1.

[0071] In this embodiment, step 6: generating a visualization map based on the viewpoint location information based on the distribution network visualization map includes:

[0072] Step 61: Obtain the viewpoint height and direction based on the viewpoint position information;

[0073] Step 62: Obtain the field of view range based on the viewpoint height and direction;

[0074] Step 63: Obtain fusion information within the field of view based on the field of view range;

[0075] Step 64: Obtain the generated power distribution network visualization diagram;

[0076] Step 65: Render the distribution network visualization map based on the fusion information within the field of view to generate a visualization map based on the viewpoint location information.

[0077] For example, see Figure 3 First, determine the quadtree index within the current view range based on the current viewpoint height and direction.

[0078] For quadtree indexed data outside the viewport, unload PagedLods. Simultaneously, traverse all model data indexed within the current viewport to create PagedLods. Assign appropriate LOD models based on the distance from the graphics to the viewpoint, and set the display distance of the LOD model based on its size and complexity. At lower viewpoints, the display distance of the LOD can be appropriately reduced to improve rendering speed.

[0079] The amount of graphic data that needs to be loaded is determined based on the viewpoint distance.

[0080] Check if the data exists in the cache. If it does, pass the graphics memory pointer to the rendering pipeline. Otherwise, read the data via I / O and then pass the memory pointer to the rendering pipeline.

[0081] The distribution network visualization method in this application utilizes the IEC61968 / IEC61970 technical specifications, which can establish digital models and topology models of distribution networks in any province, city, or even the whole country.

[0082] This application integrates basic data from multiple business departments such as marketing, operation and maintenance, dispatching, and safety supervision to achieve multi-source data fusion; and utilizes spatiotemporal big data analysis methods to intelligently analyze and dynamically display the operating status of the distribution network in real time.

[0083] This application uses real-time calculation and real-time asynchronous rendering core algorithms to dynamically render the operating status of a single map of the province's power distribution network.

[0084] This application combines equipment and spatial information based on a geographic information system to meet the requirements of 3D visualization of resources; establishes a scheduling digital model to realize the splicing of main and distribution networks; establishes a marketing data model to realize the association between users and circuits to form an integrated power consumption model of the power distribution network; and establishes a user acquisition digital model to realize real-time access to power outage and power on-time data and near real-time access to measurement data, so as to complete the timely update of power outage and power on-time information and the display of abnormal equipment information.

[0085] By stitching together data models from different business departments and addressing problematic data, and by fully integrating basic data from multiple business departments such as PMS, dispatching, procurement, marketing, and safety supervision, the system ultimately achieved a unified power grid map display and business applications for distribution network operation based on the Siji Map.

[0086] Through core algorithms of real-time calculation and real-time asynchronous rendering, the operation status of a single map of the power distribution network in the entire province is dynamically rendered, and the spatiotemporal data interaction and visualization of the power grid are efficiently realized.

[0087] The system automatically monitors abnormal changes in line losses and intelligently analyzes possible causes from three aspects: abnormal data collection, distribution network anomalies, and file changes. It proactively issues supervisory work orders to the mobile terminal of the power supply station manager, realizing a single line for automatic monitoring, intelligent analysis, proactive management, and closed-loop management of abnormal line losses.

[0088] This application integrates with production and marketing operations, using power outages and other events as entry points and work plans as the source, to complete a seamless safety supervision process that includes on-site surveys, work permits, work execution, safety supervision, work evaluation, and assessment, achieving 100% safety control over key aspects of distribution network maintenance operations.

[0089] This application queries and locates the application location according to customer needs. Based on the power supply radius, available equipment capacity, attribute information, negative list, line corridor, etc., it automatically generates three business expansion consultation alternatives, visualizes the power supply path, and intelligently calculates the project cost.
