Fig. 2 is " 220kV double-bus route protection " GOOSE reception standard line schematic diagram based on " six is unified ".
Embodiment
Below the present invention program is described in detail.
The empty terminal matching process based on " six is unified " standard of the present embodiment comprises the steps:
1, Criterion equipment template
According to the empty terminal interface definition of " six is unified " authority file to all types of equipment, create the interface definition of all types of equipment, each device type comprises output data set dsGOOSE and dsSV and input data set dsGOOSEIn and dsSVIn, and (input data set is similar to output data set, the data acquisition of all input paths), merge input and output data set thus create standard device template, equipment standard template is the daughter element that the empty terminal of template connects, therefore need to ensure that the description with " six is unified " specification is completely the same, just can guarantee the correctness of subsequent check.
2, the empty terminal of Criterion connects template
The empty terminal of standard connects needs the standard device template completed based on previous step to carry out connection establishment, see accompanying drawing 1, accompanying drawing 2, consider different electric pressure, the otherness of the empty terminal interface of different main wiring mode equipment and the empty terminal line otherness brought, therefore, when drawing template establishment, the mode by 3 grades of indexes is stored.Wherein, electric pressure comprises: 10kV, 35kV, 66kV, 110kV, 220kV, 330kV, 500kV, 750kV etc.The mode of connection comprises: single busbar, single mother partition, single female 3 segmentations, double-bus, double-bus two segmentation, bus single-subsection, 3/2 wiring etc.Device type comprises: route protection, bus protection, tranformer protection, breaker protection, stub protection, mother (segmentation) protection, capacitor protection, change used (ground connection change) protection, reactor protection, merge cells, intelligent terminal etc.
The present embodiment; to the empty connecting terminals line template of 220kV double-bus route protection; need by 220kV double-bus the mode of route protection 3 grades of indexes store; to store content be this equipment as the SV of take over party connects and is connected with GOOSE; connecting at empty terminal in the establishment first of template needs manual line to complete, and therefore constantly sets up and is connected with the empty terminal of standard of improving the basis that template base is follow-up empty terminal line verification.
3, the coupling key word that the empty terminal of standard connects template is obtained
Line for each IED of SCD file carries out batch when verifying, how corresponding template is found to be maximum difficult point to each IED, the present invention proposes and solve according to the mode that IED describes and IEDname carries out matched and searched as key word, the extraction of key word creates when standard connects template in previous step extracts automatically.
In the present embodiment; to the empty connecting terminals line template of 220kV double-bus route protection; its empty terminal line needs to be stored by the mode of 220kV Shuan Muxian route protection 3 grades of indexes; key word then relies on storage index automatically to extract; consider that engineering is actual, IED describes extraction key word and is: 220kV line is protected.IEDname extracts key word: PL22, if can introduce the mode of connection, so key word and path indexing will form fixing and unique corresponding relation, then corresponding empty terminal can be found to connect template file by path indexing after the match is successful.
4, the parsing of SCD file
By the IED parsing module of SCD, obtain the IED list in all stations, resolve IED and comprise IED description and IEDname.By the Inputs parsing module of SCD, obtain the inputs information of IED in all stations, and find the mapping relations of the description of transmitter side and receiver side according to index path.
6, the selection of the mode of connection
In Practical Project, because in SCD file, IED description and IEDname only comprise electric pressure and device type, lack the description of butted line mode, therefore in template matches, lack the index of the mode of connection, and due to transformer station's generally maximum 3 electric pressures, provide the mode of artificial amendment interface can't to increase too many workload by default behavior process.
7, IED is connected the coupling of template with the empty terminal of standard
According to the IED list of resolving in SCD file, comprise IED and describe and IEDname, mated successively with the matching module of template by IED.Matching principle can need definition according to user, preferentially can describe according to IED and mate according to IEDname, also can preferentially according to IEDname again according to IED profile matching, or both mate simultaneously.
1) preferentially mate according to IEDname again according to IED description
First describe key word according to IED to mate, the match is successful then forms binding relationship; Mate unsuccessful, then mate according to IEDname, the match is successful then forms binding relationship; Mate unsuccessful, then information of pointing out that the match is successful.
2) preferential according to IEDname again according to IED profile matching
First mate according to IEDname, the match is successful then forms binding relationship; Mate unsuccessful, then describe key word according to IED and mate, the match is successful then forms binding relationship; Mate unsuccessful, then information of pointing out that the match is successful.
3) IED describes and mates with IEDname simultaneously
First describe key word according to IED to mate, the match is successful then mates IEDname, and the match is successful then forms binding relationship; Other situations then think that coupling is unsuccessful, prompting the match is successful information.
The present embodiment illustrates: to the qin line protection of PL2201:220kV south; describe key word " protection of 220kV line " and " 220kV is double bus scheme " according to IED, then can complete the matching relationship of " the qin line protection of 220kV south " and " 220kV double-bus route protection template ".Also the matching relationship of " PL2201 " and " 220kV double-bus route protection template " can be completed according to IEDname " PL22 " and " 220kV is double bus scheme ".
8, the correction of template matches
Template matches is not had successfully or the completing by manually revising link of matching error, thus ensure the accuracy of template matches.
The present embodiment, for the protection of PZ1001:10kV prepared auto restart, does not find corresponding template, and Auto-matching failure, mates with " 10kV mono-mother partition prepared auto restart template " by the mode manually revised.
9, empty terminal connects verification
Based on above step, the IED in SCD file sets up bundle relation with corresponding template, can carry out empty terminal and connect verification.Empty terminal verification verifies successively according to the empty terminal line of principle to all IED of profile matching, and generates check results.
10, check results is shown
Showing interface is intuitively carried out for empty terminal check results, color marking is carried out to difference section.
