Fig. 2 is a structural representation of apparatus of the present invention.
Embodiment
For ease of understanding the present invention, be described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of transformer substation virtual terminal that the present invention proposes connects configuration method of calibration, and detailed process is as follows:
S101, from SCD file, extract the connection configuration information of the empty terminal of IED;
Connecting the verification of configuration for realizing the empty terminal of Intelligent transformer station, first needing with IED(IntelligentElectronic Device, intelligent electronic device) extract the connection configuration information relevant to this IED for unit.
Being the transmission of GOOSE and SV control information transmission in communication network and receiving corresponding relation of empty terminal arrangement coupled reaction between IED.And SCD(Substation Configuration Description, substation configuration description) file is as the integrated product of system configuration, contain the system configuration information that full station is all, comprise IED and send GOOSE (Generic Object Oriented Substation Event, transformer substation case towards general object) and SV(sampled value) messaging parameter of control information, the receivable GOOSE message and SV message content etc. coming from other device of IED.What can extract from SCD file specifically mainly comprises GOOSE transmission information, GOOSE reception information, SV transmission information, SV reception information four class, shown in table specific as follows in order to describe single IED void terminal connection configuration information:
Table 1GOOSE sends information
Table 2GOOSE receives information
Table 3SV sends information
Table 4SV receives information
S102, utilize the connection configuration information generating identification symbol of the empty terminal of IED;
The verification of configuration is connected for realizing empty terminal, the empty terminal arrangement information of the IED for extracting is needed to generate unique identifier, the configuration information of what this identifier was unique the identify empty terminal of current I ED, any change of the empty terminal information of IED finally all will reflect in identifier.
Utilize the connection configuration information generating identification symbol of the empty terminal of IED, concrete steps can be:
Obtain CRC(Cyclic Redundancy Check) check code, with CRC check code for identifier.
First, the connection configuration information of empty for the IED extracted terminal can be expressed with the form of binary stream, binary stream can be one section of internal storage data in computer program, or the binary data file on disk, and concrete form can be selected voluntarily by computer program.
Secondly, connection configuration information and the CRC generator polynomial of the empty terminal of the IED after Binary Conversion is utilized; During generator polynomial, can select to be widely used and standardized 32 CRC generator polynomials, such as, X32+X26+X23+...+X2+X+1 or X32+X28+X27+...+X8+X6+1.Certainly, also CRC generator polynomial can not be specified, as long as safeguard that the computer program of check code adopts same generator polynomial.
Finally, by 32 of binary data and agreement for CRC generator polynomial is applied in algorithm, corresponding CRC check code, and identify the empty terminal of IED with this and connect configuration.
S103, the connection utilizing identifier to verify the empty terminal of IED configure.
Based on the identifier generating algorithm accessible site of CRC check code in Intelligent transformer station system configuration utility, also can be used as independently computer software to run, no matter run in what manner, software is all to reflect that the SCD file of full station system configuration information is for data source, when system configuration changes, then upgrade corresponding identifier.
For identifying the change of the connection configuration of the empty terminal of single IE, be required to be each device in transformer station and all generate corresponding identifier, the identifier of generation can write in SCD file in the attribute characterizing IED configuration version (configVersion).
Equally, for the empty terminal characterizing full station connects configuration, the empty terminal of comprehensive all IED can connect configuration information, and the empty terminal applying CRC algorithm to obtain full station connects configuring identifier, the identifier of generation can write in the version property of SCD file; Wherein, the path of opening the version property of SCD file is Header->History->Hitem-Great T.GreaT.GTVersion attribute.
Identifier generates or after having upgraded, extracts by IED configuration tool, and under be filled in device, this identifier of application of installation identification, and showing in device liquid crystal panel.
Thus, the step utilizing identifier to verify the connection configuration of the empty terminal of IED is specifically as follows:
Identifier is write in SCD file in the attribute characterizing IED version;
SCD file with identifier is converted to CID(Configured IED Description, the IED of instantiation describes) file;
Each IED, from CID file, obtains corresponding identifier;
When the identifier of each IED changes, then upgrade corresponding identifier;
When the identifier of each IED does not change, then do not upgrade corresponding identifier.
The present invention by obtaining SCD file from IEC61850 model, and SCD file, as the integrated product of system configuration, contains the system configuration information that full station is all; The connection configuration information of the empty terminal of IED can be extracted thus; Then the connection configuration information of the empty terminal of IED is utilized to generate the identifier of unique identification IED; The connection configuration of the empty terminal of IED is verified according to each identifier; Fill up in Intelligent transformer station implementation process the blank that effectively cannot verify empty terminal and connect configuration, the efficiency that the design and running that can improve Intelligent transformer station is safeguarded, reduce the risk of errors of digital transformer substation operational management, ensure safe operation of power system.
Please refer to Fig. 2, the present invention also proposes a kind of transformer substation virtual terminal and connects configuration calibration equipment, comprising:
Configuration information extraction unit 201, for extracting the connection configuration information of the empty terminal of IED from SCD file;
Identifier generating unit 202, for the connection configuration information generating identification symbol according to the empty terminal of IED; The empty terminal arrangement information of identifier unique identification current I ED; Concrete, identifier generating unit 202 converts the connection configuration information of empty for IED terminal to binary data; Utilize connection configuration information and the CRC generator polynomial of the empty terminal of the IED after Binary Conversion, obtain CRC check code, with CRC check code for identifier;
Verification unit 203, for the connection configuration according to the empty terminal of identifier verification IED.Concrete, identifier writes in SCD file in the attribute characterizing IED version by verification unit 203; Convert the SCD file with identifier to CID file; Each IED, from CID file, obtains corresponding identifier; When the identifier of each IED changes, then upgrade corresponding identifier; When the identifier of each IED does not change, then do not upgrade corresponding identifier.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
