A method for automatic connection of virtual circuits in smart substations

Abstract

The invention discloses an intelligent substation virtual circuit automatic connection method. Based on the primary main wiring diagram and the primary and secondary device associations, the IED is automatically matched to the secondary device roles associated with the typical interval defined by the typical interval virtual loop template file, and then the virtual loop connection is automaticallyestablished for the IED according to the virtual loop group and the virtual loop keywords in the template. Using this method in intelligent substation design and configuration, You can draw the primary wiring diagram once, and after the primary and secondary device associations are configured. The implementation tool automatically configures the virtual loop connection between IEDs, avoids the disadvantages of repeated configuration of the virtual loop and manual connection, significantly shortens the system integration time, and can automatically check the virtual loop of the SCD file that has completed the configuration of the virtual loop, and check whether there is any connection error or omission.

Description

technical field [0001] The invention relates to an automatic connection method for a virtual circuit of an intelligent substation, in particular to an automatic connection method for a virtual circuit of an intelligent substation based on primary and secondary equipment correlations, and belongs to the technical field of automatic operation and maintenance of electric power systems. Background technique [0002] The smart substation replaces the secondary circuit with optical cable and software logic, and uses the substation configuration description file SCD file to describe the secondary system configuration of the whole station, including the complete virtual terminal connection relationship between the secondary equipment, that is, the virtual circuit, so the configuration of the virtual circuit becomes intelligent. The focus of substation design and configuration. At present, the usual process of system integration is to first conduct a system design by the design insti...

Problems solved by technology

Therefore, in the design link and configuration link, the virtual loop connection of the whole station is repeatedly generated twice, one is reflected in the virtual terminal connection relationship table, and the other is reflected in the SCD configuration, and because the number of virtual loops in the whole station is large, manual connection It is easy to make mistakes, difficult to troubleshoot, and lays hidden dangers for subsequent debugging and testing work
