Description
Technical Field
The invention relates to the field of configuration file management and control of intelligent substations, in particular to an automatic loading method and system for configuration files of an intelligent substation.
Background
The intelligent substation system configuration file (SCD file) comprises the configuration of the intelligent electronic equipment in the whole substation, communication parameters and substation information, and the virtual terminal connection in the file reflects the corresponding connection relation of the secondary equipment in the substation, and is the key of the transmission of the electric quantity information in the whole substation and the core of a secondary system. The SCD file side confirmed by professional engineers can be loaded into a corresponding equipment system, and the accuracy and consistency of the SCD file are the key points of safe and stable operation of the intelligent substation. When a gap file needs to be modified when reconstruction and extension are carried out on site or other work needs to be carried out, the gap file needs to be exported and modified on the original SCD file, the change of an actual circuit connecting line cannot be seen after the SCD file is modified, and only a manufacturer manually compares a code and a virtual terminal connection table to ensure the correctness. The consistency aspect emphasizes that the version of the SCD file loaded into the secondary device needs to be consistent with the final version of the SCD file to be manufactured and modified, and any modification change affects the connection correspondence of the secondary device in the station.
In the prior art, technical personnel mainly use direct connection equipment of a personal notebook computer to load the SCD files after the loading of the SCD files is completed through software, and the traditional manual method has the following defects: (1) the phenomenon of modifying while debugging and optionally modifying generally exists in the field debugging process, and the SCD file flows to equipment manufacturers and debugging and operation scheduling departments, so that the consistency and the correctness of the SCD file loaded into the equipment are difficult to ensure; (2) the notebook computer used as a loading tool has a safety risk, once the SCD file is infected with a virus, a large-area network security incident may occur, and the existing secondary equipment is not basically configured with a virus checking and killing function, which brings a great potential safety hazard.
Although researchers have proposed a series of improved management and technical methods for enhancing the management and control of the SCD file, and maintaining the consistency of the version number and CRC check code, the chinese patent application for invention (CN 109285086) "an intelligent substation SCD file management and control system" discloses a management and control system for the SCD file of an intelligent substation including a workstation for operating and managing a configuration file, an engineer workstation, a IED for process level configuration and CRC monitoring, wherein the SCD file in the configuration file management server is compared with the CRC check code of the SCD uploaded by the IED for process level configuration and monitoring, and then the SCD file in the workstation for operating and managing the configuration file is modified if the CRC check code is wrong, it is likely that the modified SCD file is not the desired version and thus it is still difficult to ensure consistency, in fact the most efficient operation is to modify the SCD file directly from the secondary device. In addition, in the manual open loading mode of the existing SCD file, the consistency and the correctness of the SCD file are always influenced by the openness in the loading process. The problem to be solved is to further reduce the openness, reduce the manual intervention from the confirmation of the SCD file of the final version to the loading process of the device and improve the automation and safety controllable level of SCD loading.
