As shown in Fig. 2, the course of work of the invention is described in detail:
The reading of SCD file and virtual terminator；
Virtual terminator table needs to pre-process virtual terminator table before reading in, including typical spacing materialization and IED title are returned
One changes, and so-called typical spacing materialization refers to when issuing virtual terminator table, is issued for typical spacing, and virtual terminator table is read
Enter whole station void to be read in circuit, thus typical spacing materialization be exactly to adding a prefix before typical spacing middle IED title, i.e., it is double
Number, is extended to specific interval.In addition in read-in process, it is desirable that the same IED title must be unique, such as main transformer high pressure
Side combining unit, the sometimes referred to as side main transformer 220kV combining unit, different IED names cause program can not automatic identification, and
The normalization of IED title is exactly to be searched entire virtual terminator table, replaced, and the title of the same IED is unified.
The comparison of virtual terminator table and SCD file；
It needs to establish IED title in IED title in virtual terminator table and SCD file before comparison and map.IED is in virtual terminator table
In indicated with Chinese character, the form in SCD file but with " English+number " indicates, and each producer IED naming method is not
It is identical to the greatest extent.Therefore the disunity needs of IED naming method establish a contingency table before comparison, and program is made to understand virtual terminator table
With the corresponding relationship of IED in SCD file.
Compare principle: it is different from traditional substation, there are the feelings of " multicast " in each IED signal exchange of intelligent substation
Condition, for publisher's virtual terminator, subscriber's virtual terminator may be multiple, and determine subscriber's virtual terminator of a LC, hair
Cloth side's virtual terminator will uniquely determine.Based on this, for a LC, if virtual terminator table is consistent with subscriber's virtual terminator in SCD file,
Then publisher's virtual terminator is centainly identical, otherwise judges this LC configuration error；If subscriber's virtual terminator exists in virtual terminator table,
It is not found in SCD file, is then judged to leaking even LC；If subscriber's virtual terminator exists in SCD file, in virtual terminator table not
It finds, is then determined as redundancy LC.Finally, setting counters count leakage connects, redundancy and mistake connect LC item number.
The comparison of SCD file modification front and back；
Unit is integrated when intelligent station increase-volume or defect elimination and needs to modify IED configuration file, is had modified which content, why is repaired
Change, change can or can not run other IED and have an impact, on the one hand these problems need to make a record.On the other hand operation people
Member should have discrimination capabilities, the firsthand information that cannot be provided by integrated unit merely, if integrator because of the hand reasons such as accidentally, accidentally
A LC is deleted, then consequence is hardly imaginable.Modification front and back SCD file is compared using the instruments of inspection of the invention, it is both clear
Difference, and check on to integrate the work of unit, improve functional reliability.
