As shown in Figure 2, the course of work of the present invention is described in detail:
Reading in of SCD file and empty terminal;
Empty terminal table needs to carry out pre-service to empty terminal table before reading in, comprise typical interval to specialize and the normalization of IED title, when so-called typical interval is specialized and is referred to lower apprehensive terminal table, be spaced apart example with typical case to issue, and empty terminal table is read in and will be read in empty loop, full station, therefore typical interval is specialized is exactly that i.e. two numbering, is expanded to concrete interval to adding a prefix before IED title in typical interval.In addition in read-in process, require that same IED title must be unique, such as main transformer high-pressure side merge cells, be sometimes referred to as main transformer 220kV side merge cells, different IED names causes program automatically to identify, and the normalization of IED title is searched whole empty terminal table, replaced exactly, the title of same IED is unified.
The comparison of empty terminal table and SCD file;
Need IED title in IED title in empty terminal table and SCD file to set up before comparison to map.IED represents with Chinese character in empty terminal table, but represent with the form of " English+numeral ", and each producer IED naming method is not quite similar in SCD file.Therefore the disunity of IED naming method needs before comparison, set up a contingency table, makes program understand the corresponding relation of IED in empty terminal table and SCD file.
Comparison principle: different from traditional transformer station, there is the situation of " multicast " in each IED signal exchange of intelligent substation, for the empty terminal of a publisher, the empty terminal of subscriber may be multiple, and determine the empty terminal of the subscriber of a LC, the empty terminal of publisher will uniquely be determined.Based on this, for a LC, if empty terminal table is consistent with the empty terminal of subscriber in SCD file, then the empty terminal of publisher is necessarily identical, otherwise judges this LC configuration error; If the empty terminal of subscriber exists in empty terminal table, do not find in SCD file, be then judged to Lou to connect LC; If the empty terminal of subscriber exists in SCD file, do not find in empty terminal table, be then judged to be redundancy LC.Finally, counters count is set and leaks company, redundancy and wrong even LC number.
Comparison before and after SCD file amendment;
When intelligent station increase-volume or defect elimination, integrated unit needs amendment IED configuration file, have modified which content, why revises, and change can or can not run other IED and have an impact, and these problems need to make a record on the one hand.Operations staff should possess discrimination capabilities on the other hand, and can not rely on merely the source book that integrated unit provides, if integrator is because of reasons such as hand mistakes, deleted a LC, then consequence is hardly imaginable by mistake.Adopt the instruments of inspection of the present invention to SCD file comparison before and after amendment, the two difference clear and definite is also for the work of integrated unit is checked on, and improves functional reliability.
In addition, intelligent station increases sharply in number in recent years, the file of SCD file becomes an important process, from newly-built station puts into operation, to defect elimination, increase-volume, enlarging, which LC the file of amendment front and back SCD file, have modified each time, all will have a detailed record, and empty in-circuit testing instrument contributes to setting up this archives.
