Description
Technical field
The invention belongs to power system automation technology field, and in particular to a kind of intelligent substation based on model decoupling
Reorganization and expansion change impact analysis method.
Background technology
Increasingly perfect with intelligent substation correlation technique, intelligent substation steps into the extensive practical stage, former
The network data flow for having the packed height coupling of directly perceived, separate data is substituted, the whole station being aggregated to form by each ICD
SCD file replaces direct basis of the design drawing as debugging, O＆M and reorganization and expansion.
SCD (Substation Configuration Description) is whole station CONFIG.SYS, and it is contained
Whole transformer station whole IED device configuration informations, communication information and virtual secondary circuit annexation.In the system integration and test stage,
It is all IED device configurations, the basis of interoperability checking, is equipment operation, daily O＆M, engineering in the substation operation stage
Manage the important configuration file relied on.Currently, SCD file can meet secondary equipment of intelligent converting station and the system integration well
The demand of application, it is the unified data source of whole station, describes the communication between all IED exemplary configuration and messaging parameter, IED
Configuration and transforming plant primary system architecture, and signal related information.
Intelligent substation technology determines that the O＆M process of intelligent substation configures highly dependent upon the SCL based on XML technology
File, such as SCD, CID, ICD file.When transformer station's reorganization and expansion is related to the modification and upgrading of SCD file, due to SCD file
The reason such as the coupling of different application type information and the configuration of equipment room Quadratic Imaginary loop complex relationship be present, it is difficult to define SCD file
Amended coverage, objectively cause the phenomenon of " pulling one hair and move the whole body ".
Therefore, when carrying out reorganization and expansion to transformer station and O＆M overhauls, it is necessary to further inquire into highly integrated SCD texts
The decomposition measure of part, there is provided isolating partition configuration information changes the means of coverage, reduces the complexity of SCD file application,
The scope that change for SCD file influences is analyzed, and can preferably properly protect measure, while is reduced unnecessary big
The power failure of area and debugging efforts repeatedly.
Such as the upgrading of certain engineering main transformer protection, model file renewal.Descend assembling to put again after SCD file renewal, complete master
Become protection and each side combining unit, the whole group checking test of intelligent terminal.Tranformer protection needs to jump section gap, segmentation simultaneously
Intelligent terminal is in running status, and according to theory analysis, we only need to verify the related equipment of Transformer Protection IED in SCD
Empty terminal situation of change, the independent checking of change be present.But in Practical Project, because configuration tool lacks necessary technology
Means go to verify, the scheme taken be still actual transmission checking tranformer protection can correct tripping correlation intelligent terminal, really
Recognize it is errorless after recover power transmission again.The method of this " seeing is believing " expand transformation the cycle, really using expand power failure range as
Cost, it is ensured that protection act behavior correctness.
And for example certain 220kV double-bus intelligent station Enlargement engineering line segregation, SCD file need to increase interval circuit guarantor newly
Shield, combining unit, intelligent terminal.Empty terminal line is connected after importing ICD files, the empty terminal loop of bus protection becomes
Change, it is necessary to which again lower fill process layer configuration file.Due to the impact analysis function after empty terminal change in existing SCD configuration tools
It is not implemented, assembling, which postpones us, under bus protection does not have effective means to go the configuration variation of intellectual analysis bus protection to influence ripple
And scope, unique uniformity verification method are whole group transmissions.For expansion spacing, original spacing devices are that operation is set
It is standby, to complete the drive experiments between reorganization and expansion equipment and operational outfit, it is necessary to operational outfit is stopped transport, this needs to expand power failure model
Enclose, even whole station has a power failure sometimes.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of intelligent substation reorganization and expansion change impact analysis based on model decoupling

Same Template Information, so it is beneficial to import newly-increased IED device model templates conflict comparison (i.e. in unrelated interval SCD texts
When part imports newly-increased model file, processing template conflict), described Template Information is in SCD file
DataTypeTemplates element informations, main content are the data type of Definition Model file, while unrelated gap model
SCD file with influenceing possess identical Header information in gap model SCD file, for file repair by described Header information
Change record, including version, modification time, modification people, modification reason, modification content etc., " identical " is meant at unrelated interval
Model SCD file preserves the partial information simultaneously with influenceing in gap model SCD file, it is therefore an objective to can inquire modification and go through
History information, while in gap model SCD file is influenceed, import after newly-increased IED device models, it is necessary to add modification note
Record, it is to need to handle part modification record in merging, is easy to write modification information when merging, for influenceing to be spaced between nothing to do with
Existing empty terminal information, is retained in two model files respectively between, (influences void be present between the nothing to do with interval of interval
Terminal related information, this partial information should be retained in two model files respectively, the empty terminal for being easy to limitation to complete
Configuration information) it is easy to limit this side joint receiving end；

S7.3：After completing female difference debugging, the soft pressing plate of bus differential protection expansion spacing SV receptions is exited, GOOSE exports soft pressing plate；
S7.4：Recover the soft pressing plate of bus differential protection function and the soft pressing plates of SV, exit the soft pressing plate of maintenance；
S7.5：Whether observation difference stream is abnormal, if without exception, the interval GOOSE that puts into operation exports soft pressing plate.
