Description

Technical Field

[0001] The present invention relates to the application field of digital twin substation technology, and in particular to an automatic update method and system for interval renaming of a substation digital twin system. Background Art

[0002] Under the background of the transformation of substations to intelligent and green ones, and the acceleration of the construction of a new substation operation and maintenance mode of "unmanned operation + centralized control", in order to achieve information security between different equipment in smart substations, the equipment deployment in smart substations is divided into four major areas, among which safety areas I and II are production control areas, which mainly complete the monitoring and control functions of substation equipment, and operate substation monitoring systems, synchronous phasor measurement, intelligent recorders, comprehensive application services and other systems; safety areas III and IV are intelligent operation and maintenance information management areas, which are mainly used for dispatching production management and operation and maintenance automation information management, and operating auxiliary control, online inspection, digital twin and other systems. The deployment of multiple systems in the four major areas is complicated and works at the same time, each of which processes business and connects to various master stations, which puts higher requirements on the ability of comprehensive data processing and collaborative adaptation between systems.

[0003] During the implementation of the smart substation project, due to the unified device model, backup measurement and control devices will be used in the station to configure non-operational intervals. However, the interval names of non-operational intervals have not been determined, so the monitoring system of the substation is generally named after the backup intervals. When a large number of backup intervals are changed to operational intervals, the operation and maintenance personnel need to rename the backup interval names according to the specific dispatching interval names. In addition, the daily maintenance and interval transformation of smart substations will also require the renaming of substation interval names, which brings about the work of synchronously modifying the related information related to the interval name changes in various on-site operation and maintenance systems. At the same time, manual verification and inspection are required, which is cumbersome and redundant, and prone to incorrect changes and omissions. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides an automatic update method and system for interval renaming of a substation digital twin system, so as to solve the technical problem of automatic update of substation interval renaming.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions.

[0006] The present invention first discloses an automatic update method for interval renaming of a substation digital twin system, the method comprising the following steps:

[0007] Step 1: Deploy a digital twin system in Zone III of the intelligent substation. Based on the SCD and SDD model files, establish the device twin models of the intelligent substation, and obtain the four-remote point quantity mapping based on the forwarding point table RCD file, and associate the information class attributes of the device twin models;

[0008] Step 2: When on-site bay renaming is required for the intelligent substation, modify the bay renaming and the association of the monitoring system in the monitoring system of Zone I of the substation, and generate a bay renaming information file. Use the system configuration tool integrated in the monitoring system to modify the SCD and SDD model files involved in the bay renaming, and send the bay renaming information file, SCD, and SDD model files to the integrated application host in Zone II of the substation through SFTP;

[0009] Step 3: Run the integrated data service system on the integrated application host, regularly monitor the received bay renaming information file, realize the associated update of the diagram and the library, and automatically generate a new forwarding point table RCD file. Push the bay renaming information file, SDD, SCD model files, and the generated RCD file to the specified file storage directory in Zone III through the forward isolation device;

[0010] Step 4: Use the file processing service of the digital twin system to regularly monitor the file types passed by the forward isolation device into the specified file storage directory. Automatically start processing the bay renaming information file and the RCD file after receiving the file. Update the naming and description information of the device twin models according to the renaming information file, and update the attribute description information of the corresponding attribute points of the devices in the database based on the RCD file. Automatically update the visualization content of each business application module at the front end of the system when the data synchronization of the bay renaming is completed.

[0011] The present invention further includes the following preferred solutions:

[0017] After the interval renaming modification of the monitoring system of the intelligent substation, the generated interval renaming information file includes the interval name before modification and the interval name after modification.

[0018] In Step 4, the automatic start of the processing of the interval renaming information file and the RCD file further includes:

[0019] Step 4.1: When the digital twin system monitors and receives the interval renaming information file, automatically complete the line-by-line traversal of the interval renaming information file, and compare the interval name field in each line of content with the interval name in the substation model tree of the twin system. When the interval name before modification does not exist in the twin model device tree, no processing is performed, and continue to traverse the next line; when the interval name before modification can be mapped to the interval name in the twin model device tree, perform the replacement of the name and associated content;

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] The embodiments described in this application are only a part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] The present invention provides an automatic update method and system for interval renaming of a substation digital twin system. Based on the renaming information file generated by the interval renaming of the monitoring system in Zone I of the intelligent substation and the automatically updated model file, they are transmitted to the integrated application host in Zone II through SFTP connection, and a remote point table configuration file is automatically generated. The three files are transmitted to Zone III through a forward isolation device. The substation digital twin system monitors the renaming file types in the file storage directory pushed by the isolation device in real time. After receiving the relevant files, it automatically starts the traversal and retrieval of the renaming files, updates the interval renaming of the device twin model under the system, and updates the device description attributes under the renamed interval according to the remote point table configuration file, so as to ensure the consistency between the device model and visualization information of the substation digital twin system and the actual substation, meet the goal of the digital twin system for the full life cycle management of substation equipment, and effectively assist data collaboration in the on-site operation and maintenance stage, optimize the interval name modification process, so as to improve the efficiency and accuracy of data synchronization of each system during the substation on-site commissioning and transformation process.

[0037] See Figure 1 As shown, the present invention discloses an automatic update method for interval renaming of a substation digital twin system, including the following steps:

[0038] Step 1: Deploy a digital twin system in Zone III of the intelligent substation, establish a device twin model of the intelligent substation based on the SCD and SDD model files, and obtain the four-remote point quantity mapping based on the forwarding point table RCD file to associate the information class attributes of the device twin model.

[0039] As Figure 2 shown, according to a specific embodiment, in Step 1, deploying a digital twin system in Zone III of the intelligent substation further includes:

[0040] Step 1.1: Realize the data collection and storage of multiple systems in Zones I, II, and III based on various forms of data interfaces such as standard specifications and E files, realize the integrated unified management of the whole station equipment data, and support multiple applications such as panoramic monitoring, intelligent operation and maintenance, and key equipment status assessment and prediction of the substation that meet the business function requirements of substation operation and maintenance.

[0041] Step 1.2: Establish communication between the digital twin system and the monitoring system of the substation based on the IEC104 standard specification to obtain real-time data such as "remote signal" and "remote measurement" of the substation operation.

[0042] Step 1.3: Establish communication between the digital twin system and the integrated data service system of the integrated application host in Zone II based on the E file transmission method through the isolation device to obtain files such as the result information of the substation equipment model association and status analysis.

[0043] Step 2: When on-site bay renaming is required for an intelligent substation, perform bay renaming modification and associated modification of the monitoring system in the monitoring system of Zone I of the substation, and generate a bay renaming information file; use the system configuration tool integrated in the monitoring system to modify the SCD and SDD model files involved in the bay renaming; send the bay renaming information file, SCD, and SDD model files to the integrated application host in Zone II of the substation via SFTP.

[0044] According to a specific embodiment, the associated modification of the monitoring system includes associated modifications of the real-time database, graphical interface, alarm, report, integrated five-prevention, and sequence control.

[0045] Among them, after the monitoring system of the intelligent substation performs bay renaming modification, the generated bay renaming information file includes the name of the bay before modification and the name of the bay after modification.

[0046] In Step 2, cross-zone synchronization of files from Zone I to Zone II is achieved through SFTP. First, start the SFTP server and implement the SFTP synchronous file function. In the automatic update process of bay renaming, from this step onwards, subsequent steps can be automatically completed.

[0047] Step 3: Run the integrated data service system on the integrated application host, regularly monitor the received bay renaming information file, achieve associated updates of the diagram and the database, and automatically generate a new forwarding point table RCD file; push the bay renaming information file, SDD, and SCD model files, and the generated RCD file to the specified file storage directory in Zone III through the forward isolation device.

[0048] The integrated data service system of the integrated application host develops functions for automatic retrieval of bay renaming information file updates and automatic loading and invocation of bay renaming to achieve the function of automatic update of the diagram and the database.

[0049] Step 4: Use the file processing service of the digital twin system to regularly monitor the file types in the specified file storage directory passed in by the forward isolation device. After receiving the files, automatically start processing the bay renaming information file and the RCD file, update the naming and description information of the device twin model according to the renaming information file, and update the attribute description information of the corresponding attribute points of the device in the database based on the RCD file; automatically update the visualization content of each business application module on the system front-end when the data synchronization of bay renaming is completed.

[0050] In a preferred embodiment, the updated visualization content includes interval descriptions in the panoramic monitoring substation equipment list, monitoring alarm information, three-dimensional device corresponding description information, etc.

[0051] Among them, the automatic start of the processing of the interval renaming information file and the RCD file further includes:

[0052] Step 4.1: When the digital twin system monitors and receives the interval renaming information file, automatically complete the line-by-line traversal of the interval renaming information file, and compare the interval name field in each line of content with the interval name in the substation model tree of the twin system. When the interval name before modification does not exist in the twin model device tree, no processing is performed and the next line is continued to be traversed; when the interval name before modification can correspond to the interval name in the twin model device tree, perform the replacement of the name and associated content.

[0053] Step 4.2: Automatically complete the traversal and replacement of the content of the RCD file. Since the updated content of the RCD file is limited to the point table description information, match the twin model device attributes according to the four-remote information position during the traversal process, and replace the description information when the corresponding information is found.

[0054] In addition, in a further specific embodiment, when the digital twin system modifies the system model and the device point position description information according to the interval renaming information file and the RCD file, the front end of the system can normally access and display the application before the interval renaming. After the update is automatically completed, the front-end application is automatically updated.

[0055] The beneficial effects of the present invention are as follows. Compared with the prior art, the present invention provides an automatic update method and system for interval renaming of a substation digital twin system. Based on the renaming information file generated by the interval renaming of the intelligent substation area I monitoring system and the updated model file, the file update process is automatically started to complete the update of the model and description information of the digital twin system, so as to ensure the consistency between the device model of the substation digital twin system and the actual substation, meeting the goal of the digital twin system for the full life cycle management of substation equipment. Through the automatic transfer of files among various communication methods in each area of the substation station control layer, the problem of the heavy workload of synchronously modifying the associated information related to the interval name change in each on-site operation and maintenance system caused by the need to rename the substation interval due to daily maintenance, interval transformation, etc. in the intelligent substation is solved, reducing the workload of operation and maintenance personnel during system maintenance, reducing the operation and maintenance difficulty, improving the integration of the system, effectively assisting data collaboration in the on-site operation and maintenance stage, optimizing the interval name modification process, and improving the efficiency and accuracy of data synchronization in each system during the substation on-site commissioning and transformation process.
