In this embodiment, the first substation configuration description file is a substation configuration description file before the substation is rebuilt, and the second substation configuration description file is a substation configuration description file after the substation is rebuilt, that is, the second substation configuration description file is a configuration description file to be used by the substation.
The Substation Configuration description file may be referred to as an SCD (Substation Configuration description, SCD) file for short, and describes each isolated intelligent electronic device in the intelligent Substation and logical connections among the intelligent electronic devices, and also describes example configurations and communication parameters of all the intelligent electronic devices, communication configurations among the intelligent electronic devices, and a primary system structure of the Substation, so as to completely describe how each isolated intelligent electronic device is integrated into a fully functional Substation automation system. Therefore, the substation configuration description file can be used as an important basis for the operation configuration of the secondary system of the substation, and in the reconstruction and extension project of the substation, the real-time control and analysis of the substation configuration description file can make more accurate judgment on the daily operation and fault diagnosis of the substation and perform maintenance operation on each electrical device and the secondary protection circuit in the substation in time.

The device information includes information of the secondary device, and the information of the secondary device may include a device name, a device description, a manufacturer, a device model, a virtual terminal check code CRC, a model version, and the like. It should be noted that the secondary device is a device that is not directly connected with the electric energy in the substation, and is generally an auxiliary device that controls, protects, monitors, measures, and adjusts the operation of the primary device in the substation, and the primary device is a device used in a main system of power generation, transmission, and distribution in the substation, such as a generator, a transformer, a circuit breaker, a disconnector, a bus, a power cable, and a transmission line.
In this embodiment, the file specification of the second substation configuration description file is self-checked by using the device information obtained from the first substation configuration description file and the second substation configuration description file.
More specifically, in an example, a configuration file of a secondary device in the substation may be obtained from the device information, and a file specification of a configuration description file of the second substation is self-checked according to the configuration file.
The self-check may include at least one of a static check, a consistency check, and a virtual loop review. The present embodiment does not limit the sequence of each inspection in the self-inspection link.

In this embodiment, the line protection is a line having a circuit protection function in a substation and including a plurality of secondary devices. The association relationship between the intelligent electronic equipment and the newly added line protection is that the newly added intelligent electronic equipment and the newly added line protection have a common circuit protection function, and the newly added intelligent electronic equipment and the newly added line protection have a direct or indirect connection relationship. Namely, the target intelligent electronic device has a direct or indirect connection relation with the newly added line protection, and has the same protection function with the secondary device in the newly added line protection.
And S1203, taking a line interval formed by the newly added line protection and the target intelligent electronic device as an extension line interval.

In this embodiment, the essence of the extension line interval is a newly added line interval after the substation is reconstructed and extended, and the extension line interval includes newly added line protection and target intelligent electronic equipment. For example, the target intelligent electronic device in the 220kV extension line interval may include a line protection unit, a merging unit, and an intelligent terminal; target intelligent electronic devices in a 500kV incomplete string-to-complete string (extension line interval) may include line protection, line voltage combining unit, side switch protection, side switch current combining unit, side switch intelligent terminal, and so on.

In this embodiment, in order to perform omnidirectional line protection on the extension line interval, two sets of intelligent electronic devices can be usually arranged in the extension line interval, and the two sets can be mutually standby, so that the circuit fault can be conveniently solved in time. The extension line interval in this embodiment may be a line interval with a double-set configuration, for example, a line interval configured by A, B two manufacturers exists, the a sets of intelligent electronic devices in the extension line interval all belong to the a manufacturer, the B sets of intelligent electronic devices in the extension line interval all belong to the B manufacturer, and there may be a large difference between the a set of intelligent electronic devices and the B set of intelligent electronic devices, for example, there is a difference in device types, there is a difference in device data templates, and so on.
Therefore, if it is detected that the double-set configured intelligent electronic devices exist in the extension line interval, the set a of intelligent electronic devices and the set B of intelligent electronic devices in the extension line interval need to be distinguished, non-added line protection matched with the set a of intelligent electronic devices and non-added line protection matched with the set B of intelligent electronic devices can be preferentially determined in the first substation configuration description file respectively, and then the same type of line interval is determined according to the two different line protections and the two sets of intelligent electronic devices.
And S140, verifying the configuration description file of the second substation according to the difference between the extension line interval and the line interval of the same type.
In this embodiment, the extended line interval and the line interval of the same type are respectively compared with the intelligent electronic device, the access node and the virtual circuit, the difference between the extended line interval and the line interval of the same type is determined, and the configuration description file of the second substation is verified according to the difference between the extended line interval and the line interval of the same type.

The tree structure diagram of the exemplary line protection sub-node information shown in fig. 4 includes three access points S1, G1, and M1, where each access point has a plurality of pieces of LDevice sub-node information, and each sub-node includes a plurality of sub-nodes.
