Description

Technical Field

[0001] The present invention relates to the technical field of distribution network data analysis, and in particular to a distribution network graph model synchronization verification positioning analysis method and system. Background Art

[0002] In accordance with the development needs of integrated dispatching, a shared interaction mechanism is established between the distribution automation system master station and the GIS platform to reduce the complexity and workload of data maintenance, thereby achieving the goal of "one map" and "one network" for the entire network.

[0003] At present, the distribution network model data is becoming increasingly large, the accuracy is difficult to judge, and the maintenance work is difficult. The distribution network model data is pushed from the source GIS platform to the distribution automation system master station. After the distribution automation system master station parses the model, it forwards the model to the dispatching automation system master station for model splicing. Due to the coordination of multiple systems and the operation of multiple platforms, the problem of asynchronous model data often occurs, which leads to low levels of distribution network automation, low terminal remote control success rate, and low distribution self-healing rate.

[0004] In the previous working mode, the maintenance mode of the distribution network model was mainly for the distribution line team to discover problems and feedback when using the web to view the distribution network lines, and then the automation team would analyze and rectify them. The maintenance work was very passive and it was difficult to achieve normalized and efficient maintenance. In addition, the basic data quality of the distribution network model was poor, such as incorrect topology relationships, incomplete equipment parameters, and the overall efficiency of problem handling was low, which made it difficult to meet the dispatcher's requirements for monitoring the dynamic timeliness of the power grid, and it was also impossible to ensure the safe and stable operation of the distribution network. Summary of the invention

[0005] In view of the fact that the distribution network diagram data in the prior art is becoming increasingly large, the maintenance process is very cumbersome and passive, and it is difficult to achieve normalized and efficient maintenance. In addition, due to the involvement of multi-system coordination and multi-platform operation, the problem of asynchronous diagram data often occurs, which leads to a low level of distribution network automation, a low terminal remote control success rate, and a low distribution self-healing rate. In view of the current technical problems, the present invention provides the following invention content:

[0006] A distribution network graph model synchronization verification positioning analysis method, comprising the following steps:

[0007] Collect distribution line diagrams;

[0008] Analyze the power distribution line diagram;

[0009] The parsed distribution line model is combined with the updated graphic file to obtain the DFG model file and the SVG model file generated by the WEB system;

[0010] Synchronize DFG image template files and SVG image template files generated by the WEB system;

[0011] Compare the synchronized DFG model files and the SVG model files generated by the WEB system with the running DFG model files and SVG model files to generate a checklist of the latest model versions;

[0012] Check the latest version of the graphics and models in the list to see if the graphics and models of the distribution automation master station are updated synchronously.

[0013] Furthermore, the distribution line model includes SVG graphics and XML models.

[0014] Furthermore, the analysis of the power distribution line diagram mold body includes the following steps:

[0015] Receive SVG graphics and XML model information files;

[0016] Convert the parameter information filled in the SVG graphic and XML model information file into uniquely identifiable data.

[0017] Furthermore, the image model splicing specifically includes the following steps:

[0018] Identify the device ID of the distribution line model;

[0019] According to the corresponding device ID, the DFG image file and the SVG image file generated by the WEB system are matched and combined.

[0020] Further, monitoring whether the graphics update of the distribution automation master station is synchronized according to the latest graphics version verification list specifically includes the following steps:

[0021] Get the version and update time of DFG template files and SVG template files generated by the WEB system;

[0022] Compare the versions and update times of the DFG template file and the SVG template file generated by the WEB system;

[0023] If the versions and update times of the DFG model file and the SVG model file generated by the WEB system for the same feeder are inconsistent, the conclusion is judged to be abnormal.

[0024] A distribution network graph model synchronization verification positioning analysis system is used to execute the above-mentioned distribution network graph model synchronization verification positioning analysis method, including a GIS platform, a distribution automation system master station and a power grid operation management system, wherein:

[0025] The GIS platform publishes the distribution line model and sends the distribution line model to the distribution automation system master station;

[0026] The distribution automation system master station includes a real-time control area 1 and a production management area 3. The real-time control area 1 receives the distribution line model published by the GIS platform through the interface service area and generates an SVG model file; the production management area 3 synchronizes the DFG model file in operation; the distribution automation system master station compares the DFG model file and the SVG model file generated by the WEB system with the running DFG model file and SVG model file to generate a pre-released map;

[0027] The power grid operation management system reviews the version information of the pre-released diagram and the accuracy of the pre-released diagram.

[0028] Furthermore, the power grid operation management system also includes power outage application form management, and the power outage application form management obtains application results through automated review and scheduling review.

[0029] Furthermore, the automated review reviews version information of the pre-released graph.

[0030] Furthermore, the scheduling audit reviews the accuracy of the pre-released diagram.

[0031] The present invention discloses a distribution network graph model synchronization verification positioning analysis method and system. Through real-time monitoring of the distribution network graph model, abnormal graph model data can be discovered in real time, which greatly reduces the timeliness of distribution network graph model maintenance and improves maintenance efficiency. In addition, by comparing the time and version of receiving and publishing graph models in the real-time control zone 1 and the production management zone 3, abnormal graph models can be accurately located so that abnormal graph models can be quickly rectified, thereby transforming traditional passive maintenance into active maintenance, thereby improving maintenance efficiency and saving human resource costs.

[0035] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0036] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0037] A distribution network graph model synchronization verification positioning analysis method, such as Figure 1 As shown, the following steps are included:

[0038] Step S1, collecting distribution line diagram;

[0039] In an embodiment of the present application, the source GIS platform maintains the single-line diagram of the distribution line, and then pushes the distribution line diagram model to the distribution automation system master station. The collection of the distribution line diagram model mainly involves collecting the single-line diagram of the distribution line and the distribution line diagram model maintained by the source GIS platform.

[0040] The distribution line diagram model is divided into two parts: graphics and models. Graphics refer to the single-line diagram and ring network diagram of the distribution network logic connection displayed in the distribution master station, which describes the graphics and pictures of the distribution automation system. The model is a collection of distribution network equipment attributes and connection relationships in the distribution automation system master station to meet the application requirements of distribution network operation monitoring, control, analysis and calculation.

[0041] Step S2, analyzing the power distribution line model;

[0042] Further, in a preferred embodiment of the present application, step S2 specifically includes the following steps:

[0043] Step S210, receiving SVG graphics and XML model information files;

[0044] Step S220: Convert the parameter information filled in the SVG graphic and XML model information file into uniquely identifiable data.

[0045] GIS pushes SVG graphic files and XML model information files. During parsing, the parameter information filled in the model XML file pushed by GIS is converted into data that can be recognized and stored by the distribution automation system, which is convenient for subsequent graphic model splicing; in this embodiment of the application, the distribution automation system automatically parses the graphic model file.

[0046] Step S3, combining the parsed distribution line model with the updated graphic file to obtain a DFG model file and an SVG model file generated by the WEB system;

[0047] Graphic-model splicing is to match and combine graphics with model parameters to update the system single-line diagram. The master station of the distribution automation system uses the device ID of the graphic-model file as the identification condition for matching and splicing.

[0048] In the embodiment of the present application, DFG is a real-time control zone one graphic model file, SVG is a production management zone three graphic model file, and the generated SVG file is used to display the production management zone three graphic model.

[0049] Furthermore, in a preferred embodiment of the present application, the image splicing in step S3 specifically includes the following steps:

[0050] Step S310, identifying the device ID of the power distribution line model;

[0051] Step S320: According to the corresponding device ID, the DFG image model file and the SVG image model file generated by the WEB system are matched and combined.

[0052] Step S4, synchronizing the DFG image model file and the SVG image model file generated by the WEB system;

[0053] Step S5, comparing the synchronized DFG model file and the SVG model file generated by the WEB system with the running DFG model file and SVG model file to generate a latest model version verification list;

[0054] This project uses QT and C++ languages ​​to develop a program based on the LINUX system. According to the distribution network automation system, the real-time control area 1 receives GIS graphics, the synchronized DFG graphics files of the three production management areas, and the SVG graphics files generated by the real-time control area 1 WEB system, it monitors the dynamic changes of error logs and directories in real time, automatically obtains the arrival of the SVG and XML graphics currently receiving GIS, and the DFG and SVG graphics of the running graphics, as well as the update time, storage status, and generation time, generates a checklist of the latest graphics version, and promptly monitors the changes in terminal equipment when comparing the graphics versions of GIS and distribution automation systems to ensure consistency with the GIS version. At the same time, it realizes real-time monitoring of the arrival, import, and crossing of the three production management areas of red and black graphics, and real-time control of the web output of SVG in area 1, so as to promote the efficient review of power outage tickets of the Nanning power grid distribution network by automation personnel.

[0055] GIS operation and maintenance personnel publish red and black maps, transmit them to the interface server, then to the real-time control zone 1 WEB server, and finally to the production management zone 3 server; parameter comparison is performed at each link.

[0056] Step S6: Check the list based on the latest version of the graphics model to monitor whether the graphics model update of the distribution automation master station is synchronized.

[0057] Further, in a preferred embodiment of the present application, step S6 specifically includes the following steps:

[0058] Step S610, obtaining the version and update time of the DFG image model file and the SVG image model file generated by the WEB system;

[0059] Step S620, comparing the versions and update times of the DFG image model file and the SVG image model file generated by the WEB system;

[0060] Step S630: If the versions and update times of the DFG model file of the same feeder and the SVG model file generated by the WEB system are inconsistent, the conclusion is judged to be abnormal.

[0061] The judgment conclusion is exported in CSV file format for easy viewing by staff.

[0062] Furthermore, in a preferred embodiment of the present application, the power distribution line model includes an SVG graphic and an XML model.

[0063] A distribution network graph model synchronization verification positioning analysis system is used to execute the above-mentioned distribution network graph model synchronization verification positioning analysis method, such as Figure 2 As shown, it includes GIS platform, distribution automation system master station and power grid operation management system, among which:

[0064] The GIS platform publishes the distribution line model and sends the distribution line model to the distribution automation system master station;

[0065] The distribution automation system master station includes a real-time control area 1 and a production management area 3. The real-time control area 1 receives the distribution line model published by the GIS platform through the interface service area and generates an SVG model file; the production management area 3 synchronizes the DFG model file in operation; the distribution automation system master station compares the DFG model file and the SVG model file generated by the WEB system with the running DFG model file and SVG model file to generate a pre-released map;

[0066] like Figure 3As shown, the embodiment of the present invention also includes: when there is an abnormal change in terminal equipment on site, the GIS platform starts to draw a red map, the operation and maintenance unit reviews the accuracy of the red map, and if the review fails, it returns to the GIS platform to redraw it, and the operation and maintenance unit sends the red map that has passed the review to the central SOA platform. SOA, namely service-oriented architecture, is a component model that connects different functional units of an application (called services) through well-defined interfaces and contracts between these services. The interface is defined in a neutral way, and it should be independent of the hardware platform, operating system, and programming language that implements the service, which allows services built in various such systems to interact in a unified and universal way.

[0067] Combined with the primary equipment maintenance list of the power grid operation management system and the OCS three-zone WEB system, using the three-zone diagram calibration tool (diagram calibration tool, synchronization calibration tool and special character calibration tool), and using the DCS zone one SCADA system to schedule and review or remotely control the red diagram, the red diagram is converted into a black diagram, thereby publishing the official diagram.

[0068] The power grid operation management system reviews the version information of the pre-released diagram and the accuracy of the pre-released diagram.

[0069] In an embodiment of the present application, when the real-time control zone 1 sends data to the production management zone 3, the data is transmitted through a reverse isolation device. The reverse isolation device is a measure of the degree of isolation between the signal applied to the output end of the device and its input end, and is a measure of the interference of the reflected signal to the desired basic signal flow in the positive direction.

[0070] The three production management areas will also backfill the IP, which will be transmitted through the forward isolation device. The forward isolation is a measure of the degree of isolation between the signal added to the output end of the device and its input end, and is a measure of the interference of the reflected signal to the basic signal flow required in the positive direction.

[0071] Furthermore, in a preferred embodiment of the present application, the power grid operation management system also includes power outage application form management, and the power outage application form management obtains application results through automated review and scheduling review.

[0072] Furthermore, in a preferred embodiment of the present application, the automated review reviews version information of the pre-released image.

[0073] Further, in a preferred embodiment of the present application, the scheduling audit audits the accuracy of the pre-released graph.

[0074] The distribution network graph and model synchronization verification and positioning analysis system includes GIS source files, DFG files, WEB files, GIS and distribution master station production management three-zone synchronization verification results, GIS and distribution master station real-time control one-zone synchronization verification results, distribution master station production management three-zone, real-time control one-zone synchronization verification results, the latest version of the whole network GIS, graph and model data verification display, output and problem data analysis, etc., to achieve comprehensive inspection and verification from aspects such as parameter integrity, relationship validity, and topological connectivity, and intuitively display through visualization; support problem analysis and positioning, and promote efficient and high-quality graph and model interaction work. Analyze and verify the graph and model output by GIS, and quickly locate and repair the problems that arise, so as to improve the success rate of the distribution network master station graph and model import, ensure the accuracy of the distribution network master station data, and promote the safe and stable operation of the distribution network master station system.
