[0002] The secondary equipment of the substation often needs system transformation and equipment update due to the service life or function upgrade requirements. Especially with the integration of advanced functions such as one-button sequential control, the upgrade and transformation of the monitoring system has become particularly urgent. In actual operation, most of them rely on on-site upgrades and manual point-to-point by engineering personnel, but it is often difficult for substations to apply for power outage time, and the power outage commissioning and acceptance cycle is short. If there are engineering parameter configuration errors, improper SCD model configuration, anti-error logic and sequential control ticket setting problems, or communication compatibility problems between new and old equipment during the precious power outage period, it may lead to technical transformation delays and quality problems, especially within the limited power outage time, it is impossible to carry out comprehensive point-to-point testing and functional verification, which may cause safety hazards after the substation is put back into operation. Therefore, there is an urgent need for an efficient and reliable monitoring system upgrade and transformation solution to solve these problems. Summary of the invention

[0030] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, a method for upgrading and transforming a monitoring system of a smart substation in a factory includes the following steps:

[0032] (1) Back up the substation on-site monitoring system data, verify the data, and generate an on-site major version mark;

[0033] (2) Restore the backed-up data to the same type and version of monitoring system in the factory, generate the old monitoring system data in the factory, verify the data, and generate the major version mark in the factory;

[0034] (3) Export the intermediate files of the old monitoring system in the factory and import them into the new monitoring system in the factory to upgrade the monitoring system;

[0035] (4) Build a factory verification environment to verify the consistency of monitoring system data before and after the upgrade;

[0036] (5) On-site implementation

[0037] The following is a detailed description of each step in the in-plant implementation method for upgrading and transforming the monitoring system of smart substations:

[0038] Backup substation on-site monitoring system data:

[0039] The backup tool module in this system automatically discovers and marks key data based on the data structure and file path templates provided by the manufacturer to ensure the comprehensiveness and accuracy of the backup process. The graphical user interface (GUI) of the backup tool module is implemented, allowing operators to intuitively select specific data sets for backup and monitor the backup progress and status in real time. Real-time verification is performed on the backup data to ensure the integrity and accuracy of the data during the backup process. The CRC algorithm generates a unique checksum value for each file, which is then aggregated to form a large version mark. After the backup is completed, the backup tool module stores the checksum value together with the backup data, and uses AES-256 to encrypt the stored data to enhance data security.

[0040] Factory recovery:

[0041] Use the recovery tool module in this system to restore the backup data to the same type and version of the monitoring system machine in the factory. After the recovery process is completed, use the CRC check algorithm to check the recovered data again and generate the major version mark again. Verify the consistency of the data by comparing the major version mark generated by the on-site backup and the factory recovery. If the check values ​​match, it is confirmed that the data copy process is correct. In addition, the backup tool module records the logs of the backup and recovery operations in detail, including the operation time, operator, operation results and any abnormal information, to facilitate problem tracking and subsequent audits, to ensure the efficiency, security and reliability of the step of "copying the on-site monitoring system data to the factory", and to provide reliable data protection for the upgrade of the smart substation monitoring system.

[0042] In-plant upgrades:

[0043] Abstract and refine the functions of mainstream monitoring systems, and define a set of intermediate file standards that are compatible with information fields of monitoring systems of various versions and even manufacturers, and are used to export old systems and import new systems. By running the export tool module in the system, the one-click export operation of the old monitoring system data is realized to generate intermediate files. These intermediate files are copied to the new version of the monitoring system machine in the factory. Run the import tool module to complete the one-click import operation, thereby realizing the upgrade and transformation of the monitoring system. The import and export tools of the intermediate files are specifically mapped and customized by the manufacturer of the monitoring system according to the specific release version, and integrated into this system as a sub-function module.

[0044] Among them, the monitoring background intermediate file types include database intermediate files and graphic intermediate files. The database intermediate file contains primary equipment, calculation telesignaling, five-defense rules, operation tickets and operation terms, etc. The data in the file is separated by tabs. It specifically includes the device group table / interval table record DevGroup.txt, the logical node table record LogicNodeRecords.txt, the telesignaling table record YxRecords.txt, the telemetry table record YcRecords.txt, the gear table record DwRecords.txt, the primary equipment record DevRecords.txt, etc. Taking the device group table / interval table record as an example, five information fields are defined, including OID, device group name, interval name, virtual device existence, and device group alias. Interval records are matched by interval names, and those without interval names are updated by name matching to generate OID mapping; taking the logical node table record as an example, eight columns are defined, including OID, logical node name, IED name, whether to protect the node, number of telesignals, number of telemetry, number of remote controls, and device type number. Logical node records are matched by IED names, and those without IED names are updated by name matching to generate OID mapping; taking the telesignal table record as an example, 18 columns are defined, including OID, telesignal name, logical node telesignal, remote control number, terminal information, inversion, telesignal linkage REF, telesignal processing flag, direct transmission alarm level, direct transmission alarm name, device type name index number, telesignal logical node name index number, remote control logical node name index number, device name index number, measuring point name index number, dual telesignal discrimination time, logical node dual-position telesignal, and telesignal status. Telesignal records are matched by reference, and those without reference are updated by name matching to generate OID mapping. The graphic intermediate file format is a G format file, and the file content includes information such as the position of the graphic element (x, y), the reference of the graphic element associated signal, the graphic element associated signal ID, signal description, remote control reference, and the signal associated with the remote control.

[0045] The types of intermediate files of the gateway machine specifically include database intermediate files, channel intermediate files, and forwarding point table intermediate files. The contents of the database intermediate files include plant station information, voltage level, interval information, primary equipment, secondary equipment, telemetry, telesignaling, remote control and other information. The contents of the channel intermediate files include the address of the master and substation, the IP address of the AB network, the monitoring retention parameters and other information; in the forwarding point table intermediate file, telesignaling includes the forwarding table serial number, the name of the secondary equipment, the signal name, the upload type, etc.; remote control includes the forwarding table serial number, the name of the secondary equipment, and the signal name; telemetry includes the forwarding table serial number, the name of the secondary equipment, and the name of the telemetry signal.

[0046] In-factory verification:

[0047] Build a verification environment to fully verify the upgraded monitoring system to ensure the consistency of monitoring system information data before and after the upgrade and the reliability of the new system functions. The verification tool modules in this system include the bay layer device simulation module (supporting IEC61850, DL / T860 (CMS) protocol simulation), the dispatching master station simulation module (supporting 104 and extended protocol simulation), the monitoring system transmission module, and the multi-source offline verification tool. Perform offline static verification and online dynamic communication verification on the monitoring background and gateway machine respectively.

[0048] Offline static verification of the monitoring background: When upgrading and renovating within the factory, the new and old monitoring backgrounds export intermediate files respectively, including database intermediate files and graphic intermediate files. The content of the database intermediate file includes plant information, voltage level, interval information, primary equipment, secondary equipment, telemetry, telesignaling, remote control and other information; the content of the graphic intermediate file includes the position of the graphic element (x, y), the reference of the graphic element associated signal, the graphic element associated signal ID, signal description, remote control reference, and the signal associated with the remote control. Use the multi-source offline verification tool to perform consistency verification on the database intermediate files and graphic intermediate files of the new and old monitoring backgrounds respectively. If the consistency verification is correct, it means that the database information before and after the upgrade of the monitoring background is correct and the screen measurement point association is correct. If it is inconsistent, the corresponding consistency verification result file is output.

[0049] Offline static verification of gateway machines: When upgrading and modifying within the factory, the new and old gateway machines export intermediate files respectively, including database intermediate files, channel intermediate files, and forwarding point table intermediate files. The content of the database intermediate file includes plant station information, voltage level, interval information, primary equipment, secondary equipment, telemetry, telesignaling, remote control and other information; the content of the channel intermediate file includes the address of the master and substation, the IP address of the AB network, the monitoring retention parameters and other information; the content of the forwarding point table intermediate file includes the forwarding table sequence number, the name of the secondary equipment, the signal name, the upload type, etc. Use the multi-source offline verification tool to perform consistency verification on the database intermediate files, channel intermediate files, and forwarding point table intermediate files of the new and old gateway machines respectively. If the consistency verification is correct, it means that the database information, channel information, and forwarding table data before and after the gateway machine upgrade are correct. If they are inconsistent, the corresponding consistency verification result file is output.

[0050] Monitoring background online dynamic communication verification: Figure 2 As shown in the figure, in the online dynamic communication verification, the bay layer simulation tool imports the SCD of the old monitoring background to simulate the 61850 server functions of the bay layer devices such as protection and measurement and control devices, and can support the simulation of 300 or more IEDs (calculated based on 500kV smart substations). The bay layer device simulation tool parses the telesignaling and telemetry in the "background database intermediate file" as the point source, automatically triggers the telesignaling and telemetry change value, and exports the "simulation end full station data point change record" after all triggers are completed. The new monitoring background uses the data point change record module to automatically record the received telesignaling and telemetry, and exports the "background end full station data point change record" after the trigger is completed. The new monitoring background parses the remote control data in the "database intermediate file" and triggers batch sequential remote control. After all remote control commands are triggered, the "background end full station remote control record" is exported; the simulation system responds to the remote control command triggered by the new monitoring background, and exports the "simulation end full station remote control record" after receiving. Similarly, the "simulation end graphic data change record", "background end graphic data change record", "background end graphic remote control record", and "simulation end graphic remote control record" are generated. Run the multi-source offline verification tool of this system to perform consistency verification on the above pairs of record files. If the consistency verification is correct, the telemetry, telesignaling and remote control after upgrading the monitoring background will complete the communication verification. If it is inconsistent, the corresponding consistency verification result file will be output.

[0051] Online dynamic communication verification of the gateway machine: Under the premise that the offline verification of the intermediate files exported by the new and old monitoring systems is consistent, run the interval layer device simulation tool constructed by the present invention to parse the old monitoring background SCD. The interval layer device simulation tool will establish 61850 connections with the new and old gateway machines respectively, and the new and old gateway machines will be connected to the simulation master station constructed by the present invention respectively, and the data point change records of the new gateway machine and the interval layer simulation end will be generated online respectively, as well as the simulation master station record files and remote control record files corresponding to the new and old gateway machines. Figure 3As shown, the interval layer device simulation tool parses the telesignaling and telemetry in the "database intermediate file" as the point source, automatically triggers the telesignaling and telemetry change value, and exports the "simulation end data point change record" after all triggers are completed. The new gateway uses the data point change record module provided by this system to automatically record the received telesignaling and telemetry, and exports the "gateway end data point change record" after the trigger is completed. Then the new and old gateways are tested in a black box to verify the data consistency between the two. The interval layer device simulation tool parses the transfer table intermediate file of the new gateway, selects the telesignaling and telemetry as the point source, automatically triggers the telesignaling and telemetry change value, and sends the change data to the simulation master station. The simulation master station runs the data point change record module provided by this system to automatically record the received telesignaling and telemetry, and exports the simulation master station record file A and simulation master station record file B after all triggers are completed. Then the new gateway is tested in a black box for the remote control function. The simulation master station A parses the remote control data in the transfer table intermediate file as the point source, and automatically triggers the remote control to send the remote control to the old gateway. The interval layer device simulation tool responds to the received remote control and exports the remote control record file A after all remote control triggers are completed, and generates the remote control record file B in the same way. Run the multi-source offline verification tool provided by this system to perform consistency verification on each pair of record files mentioned above. If the consistency verification is correct, the telemetry and telesignaling remote control after the gateway machine is upgraded will complete the communication verification. If they are inconsistent, the corresponding consistency verification result file will be output. In addition, in the online verification of the gateway machine remote control, it is necessary to compare the transfer table intermediate file with the remote control record file to detect the problem of missed remote control sent by the master station. If the number of remote controls and IDs are consistent, it means that the dynamic remote control verification of the gateway machine has covered all remote control points in the transfer table intermediate file.

[0052] On-site implementation:

[0053] After the factory verification of the new monitoring system is completed, all import, export, transmission, and verification tools for factory upgrades and factory verification need to be deleted to ensure the purity of the new system restored on site and avoid misoperation after the system is connected to the network. During the on-site implementation phase, choose to replace the new machine upgraded in the factory or only restore its data backup to the site according to the upgrade requirements. If the latter is selected, the backup and recovery steps will be repeated, and the integrity and consistency of the data during the copy process will be ensured by comparing the major version mark, thereby achieving a seamless upgrade of the on-site monitoring system.
