Embodiment

Below in conjunction with embodiment, the present invention will be further elaborated.

Intelligent substation SCL file difference comparative approach of the present invention, comprises the following steps:

1) key assignments of SCL file key element is defined

SCL file is a kind of file following XML standard, according to the definition of IEC61850-6 standard, SCL file is made up of elements such as Communication, SubNetwork, ConnectedAP, IED, AccessPoint, LDevice, DataSet, FCDA, GSEControl, SampledValueControl, Inputs, ExtRef, LN, DOI, DAI, forms a kind of structural language of nested, self-described, band relation.The first step of SCL file difference comparative approach is exactly the key word of definition key element, also key assignments (Key Value) is referred to as, this key assignments is a property value or the combination of several property value of corresponding SCL key element, unique in the territory of an element, in order to identify different entry.The key assignments that in the SCL file that table 1 is definition, key element is corresponding.

The key assignments of table 1SCL file key element

SCL key element	Key assignments
		Communication	Communication
SubNetwoik	name
		ConnectedAp	iedName+apName
Address	Address
		GSE	ldInst+cbName
SMV	ldInst+cbName
		IED	name
AccessPoint	name
		LDevice	inst
DataSet	name
		FCDA	index
GSEControl	name
		SampledValueContro1	name

Inputs	lnputs
		ExtRef	intAddr
LN	prefix+lnClass+lnInst
		DOI	name

In table, each name uses in the element fields corresponding with it, and name key assignments as corresponding in IED key element is the name attribute of IED element fields, and the name key assignments that DOI key element is corresponding is the name attribute of DOI element fields.

2) according to the key assignments of SCL file key element of definition, SCL File Mapping is become a series of bivariate table structure that is nested, band major key, the entry of often opening bivariate table can with " major key-key assignments " right formal modeling; Here major key refers to the index entry of a tables of data, has the feature of uniqueness.

3) comparison of otherness between the bivariate table carrying out being with major key.

Between bivariate table with major key, the comparative approach of otherness is specially, and is first sorted according to Major key by the bivariate table that two SCL documents map, and forms " major key-key assignments " of ascending order arrangement to list; Again according to Major key, " major key-key assignments " after two SCL documents sequences is carried out intersection comparison to list (mapping SCL element).Concrete grammar is: as occurred that major key increases in same comparison domain, be then judged to be that SCL file key element increases item; As occurred, major key reduces, be then judged to be that SCL file key element deletes item; As occurred, major key is identical, then determine whether identical according to key assignments, if difference, is judged to be amendment.

When major key is identical, the comparison criterion of carrying out intersection comparison according to key assignments is listed in table 2,

The comparison criterion of the comparison item that table 2 major key is identical

In table, the comparison criterion of each SCL key element is its property value in corresponding key or the combination of several property value.

As an embodiment, Fig. 1 gives IED key element rear otherness comparison procedure before changing in SCL file.

In figure, carry out ascending order arrangement according to name key assignments, after change, between PL5022A and PB5023A, add PB5031A key assignments item, show that creating IED key element increases item PB5031A; Between PL5022A and PL5032A, decrease PL5022B key assignments item, show that creating IED key element deletes a PL5022B; Key assignments PL5032B item is identical, desc comparison criterion item, protects B to become 500kV days intelligent 5621 lines protect A, show that IED key element there occurs amendment by 500kV before changing days intelligent 5621 lines; Key assignments PM5002B item is identical, desc comparison criterion item is also identical with type comparison criterion item, because SCL is nested definition, containing AccessPoint element in IED key element, so continue the comparison item of comparison Accesspoint element, in Accesspoint comparison list, decrease M1 between G1 key assignments and S1 key assignments, this shows to create deleted entry, by that analogy, if the name key assignments item in Accesspoint comparison list is identical, continue comparison desc comparison criterion item

Further, according to the Software tool SCL Compare that the exploitation of SCL file difference comparative approach compares to different editions configuration file, can according to the structure of the class of configuration file definition, adopt the method compared by semanteme, more traditional txt text is more optimized by character alignments, and be applied to 220kV transformer station, in 110kV transformer station and 500kV transformer station, effectively improve efficiency and the correctness of the amendment of intelligent substation SCD configuration file, and the management to different revision configuration file in specification test process.

Below disclose the present invention with preferred embodiment, so it is not intended to limiting the invention, and all employings are equal to replacement or the technical scheme that obtains of equivalent transformation mode, all drop within protection scope of the present invention.
