Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of virtual terminator automatic connection method based on SSD file, comprising the following steps:
Step 1, virtual terminator is respectively created for all types of IED and connects template.
The corresponding file of each template, from the convenience, the information content of storage, hierarchical relationship table of the maintenance management in later period
Up to upper consideration, virtual terminator connects template and uses XML file.
If all virtual terminator connection templates of the angle parsed from program all have a file, the memory of occupancy is parsed
It consumes excessive, and uses multiple file modes more suitable, the characteristics of according to virtual terminator, template should classify, specifically such as
Table one.
The IED of substation is classified according to function, including route protection, bus protection, tranformer protection, merging list
Member, intelligent terminal, observing and controlling etc. create virtual terminator according to different Main connection forms for every class IED and connect template, contains in each template
Empty circuit after having different voltages grade to connect with the virtual terminator of different main wiring modes does not have information friendship between each template
Fork, avoids the occurrence of redundant data, causes difficult in maintenance.
The classification of one template of table
The virtual terminator connection of SCD is stored using Inputs mode, and GOOSE and SV is divided to store the company of reception under each IED
Line, received line describe the virtual terminator of exterior I ED and the connection relationship of internal virtual terminator, therefore in virtual terminator connection template
Content include four layers, first layer be receiving side IED information, the second layer be GOOSE receive and SV receive, third layer be outside
IED, the 4th layer is virtual terminator connection relationship, specific as shown in Figure 2.
