[0057] When a monitoring backend database file exists, the Object measurement point class data list in the database file is parsed to obtain the path and signal description information corresponding to different data in the list. Based on the data path in the list, the signal paths in the corresponding IED model file above are traversed to find the same path.

All remote signaling and telemetry signal data reference paths and corresponding signal descriptions are compared to generate a consistency comparison result of the monitoring backend database model.

[0059] The specific comparison method is as follows: When a monitoring backend database file exists, parse the list of Object measurement point data in the monitoring backend database file, which are remote signaling, telemetry, and remote control signals, and obtain their paths and corresponding signal descriptions. The signal path includes IED name information. Based on this, traverse the corresponding IED models in the above database, find the same path, compare the signal descriptions of the two, record the description, give the conclusion that the comparison is correct when the descriptions are the same, give the conclusion that the comparison is incorrect when the descriptions are different, and generate the final comparison result.

For a reference address with the "subEna" attribute, find all data attributes that start with "sub" in the reference's data attributes, and exclude the attributes "subEna", "subQ" and "subID". The remaining attributes are data attributes that meet the conditions for issuing the command, i.e., replacement attributes. The reference address that meets the above conditions and attributes is used as the replacement address.

The DLT860-based client function communicates with the substation bay-level equipment, obtains the model files of the bay-level equipment, and can issue replacement service commands to the bay-level equipment for remote signaling and telemetry setting, and can cancel setting. The DLT860-based client function communicates with the substation monitoring host and the integrated application server, obtaining the database files, screen files, and replacement log files of the monitoring host through file service functions, and obtaining the substation configuration description (SCD) file stored on the integrated application server through file service functions. The IEC104-based client function simulates communication between the master station and the substation real-time gateway, obtaining the remote control configuration description (RCD) file of the real-time gateway through the ASDU extended service function. The system performs model consistency comparison between the monitoring system and the interval layer devices based on the database file or SCD file of the monitoring host and the model file of the interval layer devices. It also performs communication consistency comparison between the monitoring system and the interval layer devices based on the replacement record file and trigger signal record file of the monitoring host. Furthermore, the system performs model consistency comparison between the real-time gateway and the interval layer devices based on the RCD file of the real-time gateway and the model file of the interval layer devices. Finally, it performs communication consistency comparison between the real-time gateway and the interval layer devices based on the IEC104 signal records and trigger signal records received by the analog master station.

[0099] By comparing the database files of the monitoring host with the model files retrieved from the interval layer devices, and comparing the SCD files with the model files retrieved from the interval layer devices when the monitoring host database files are unavailable, model consistency comparison between the monitoring host database and the interval layer devices is achieved. Data replacement service commands are triggered on the interval layer devices according to the information rules in the monitoring host's database files or SCD files, setting the remote signaling and telemetry signals of the interval layer devices and generating trigger records. These trigger records are then compared with the replacement record files obtained from the monitoring host, achieving communication consistency comparison between the monitoring host database and the interval layer devices. Similarly, data replacement service commands are triggered according to the information rules in the monitoring host's graphical files, setting the remote signaling and telemetry signals of the interval layer devices and generating trigger records. These trigger records are then compared with the replacement records obtained from the monitoring host, achieving communication consistency comparison between the monitoring host graphics and the interval layer devices.

[0100] The client function, based on the IEC104 protocol, communicates with the real-time gateway. It obtains the Remote Configuration Description (RCD) file from the real-time gateway by extending the ASDU service function. By comparing the RCD file with the model file retrieved from the bay-level equipment, it achieves model consistency comparison between the real-time gateway and the bay-level equipment. Following the information rules in the RCD file, it triggers replacement service commands to set the telemetry and telecontrol signals of the bay-level equipment. Simultaneously, it receives IEC104 messages via a simulated master station, comparing the triggered and received signals to achieve communication consistency comparison between the real-time gateway and the bay-level equipment.

[0101] The commissioning system includes a fully domestically developed software and hardware platform, meeting the requirements for domestic production of next-generation domestically controllable substation equipment. The system can simulate a multi-channel IEC104 master station and a DLT860 client, integrated into the substation monitoring system's acceptance and commissioning interface. It enables signal triggering from actual primary and secondary equipment, and checks the information values ​​received by the multi-channel IEC104 master station within the system. Information acceptance and confirmation operations are performed for each signal. The system records the change time of remote signaling information received by the multi-channel IEC104 master station, records the telemetry confirmation values ​​of the multi-channel IEC104 master station, and records the personnel and time of information acceptance, generating traceable acceptance records and reports.
