Abstract
The invention relates to a message correctness judging method of an IEC61850-based model file, which is technically characterized by comprising the steps of: firstly, analyzing the IEC61850-based SCD (Security Coding Device) model file, classifying model file information, carrying out packet capturing analysis on a message sent by a device, then comparing classifying information of the model file with packet capturing analysis information, distinguishing the message by the analysis device from corresponding information in the model file, and giving an analysis report. The invention has the advantages that a GOOSE (Generic Object Oriented Substation Event) sent by an intelligent substation secondary device can be intelligently analyzed, and the working efficiency of an intelligent substation in a joint debugging process is effectively increased. In addition, the invention can provide an analysis method for functions such as intelligent alarm and the like in advanced application functions of the intelligent substation.
Description
Technical field
Whether correct, based on the message correctly property method of discrimination of IEC61850 model file if the present invention relates to a kind of GOOSE message that is used to judge that the intelligent substation secondary device sends.
Background technology
Intelligent substation has obtained widespread use at present, and the key feature of intelligent substation is the configuration of whole station model file and the application of GOOSE network.Most of energy concentrates in the test of interconnecting in the debug process of intelligent substation, and the essence of the test of interconnecting is exactly whether the GOOSE message that sends of comparison substation secondary device can be received by other substation secondary devices.
At present, in the debug process of intelligent substation, all be that the artificial GOOSE message that carries out is caught; Analyze the difference of relevant information in information and the model file in the message again, the method inefficiency is owing to be artificially error message to be searched; Accuracy is not high yet, is prone to make mistakes.
Summary of the invention
The object of the invention just is to provide a kind of message correctly property method of discrimination based on the IEC61850 model file; It has solved shortcoming of the prior art; The correctness of can real-time online judging the various information of GOOSE message; Accomplish the judgement of relevant information fully based on computer program, for the intelligent substation commissioning staff provides a kind of quick, reliable GOOSE message correctly property analytical approach.
The technical solution adopted for the present invention to solve the technical problems is:
The present invention is based on the message correctly property method of discrimination of IEC61850 model file, it utilizes industrial computer in the intelligent substation, accomplishes following steps:
A, at first; GOOSE in the SCD file in the IEC61850 model file at the whole station of intelligent substation partly analyzes classification; Comprise: source, characteristic and the version number of AppID, GOID, GOCBRef, DataSet, ConfRev, priority, VLANID, GOOSE message; Extract the characteristic of these parameters, form the model file comparison database;
B, secondly; GOOSE message to substation secondary device to be tested sends is caught; The GOOSE message information that analysis captures; The GOOSE message is located: if in the GOOSE message that captures, have in any three contents and the model file comparison database certain GOOSE data set content consistent, i.e. the GOOSE message that judgement captures is consistent with the characteristic of certain GOOSE data set in the model file comparison database;
C, last; After the GOOSE message that captures is positioned; The GOOSE message information that captures is confirmed to compare with the consistent GOOSE data set information of this GOOSE message that captures one by one with in the model file comparison database; Judge inconsistent information: what relatively back GOOSE parameter attribute was consistent is correct message, otherwise is error message.
Beneficial effect of the present invention does: the inventive method can real-time online be judged the correctness of the various information of GOOSE message; Accomplish the judgement of relevant information fully based on computer program; For the intelligent substation commissioning staff provides a kind of quick, reliable GOOSE message correctly property analytical approach, its meaning mainly shows:
(1) proposition, is sorted out the information that needs are considered through the relevant information in the model file is analyzed based on the notion of IEC61850 model file comparison database, and reliable correlation data source is provided;
(2) for the debugging of intelligent substation provides fast, reliable GOOSE message correctly property analysis means.In the intellectuality that has truly embodied intelligent converting station debugging.The present invention also can be utilized in the ADVANCED APPLICATIONS function of intelligent substation, for functions such as intelligent alarm provide analytical approach.
Description of drawings
Fig. 1 is an implementing procedure block diagram of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is elaborated: detecting with certain 220kV intelligent substation is example.
At first, the whole station model file at this station is analyzed, extracted the GOOSE message characteristic information, form the model file comparison database.
Secondly; GOOSE message to the 220kV route protection PCS931 at this station sends is caught; APPID is 0001, and VLANID is 2, and configuration version number is 1; The GOOSE message characteristic information of 220kV route protection PCS931 because these three information are stood therewith in the model file comparison database is consistent, assert that therefore the characteristic information that this GOOSE message that captures is 220kV route protection PCS931 in the model file comparison database is consistent.
Then; GOOSE message characteristic information in characteristic informations such as source, characteristic and the version number of the AppID in the GOOSE message that captures, GOID, GOCBRef, DataSet, ConfRev, priority, VLANID, GOOSE message and the model file comparison database compares; Carrying out correctness one by one differentiates: carrying out correctness judgement back discovery; Information in the GOID of the message that captures and the model file comparison database does not match; The information of GOID in the model file comparison database is 0001, and the GOID information of the message that captures is 0003.
Be depicted as implementing procedure block diagram of the present invention like accompanying drawing 1, its main system adopts the industrial computer in the intelligent substation, and control section uses dsp processor, and big capacity hard disk is used in data acquisition.
Claims (1)
1. based on the message correctly property method of discrimination of IEC61850 model file, it is characterized in that, utilize industrial computer in the intelligent substation, accomplish following steps:
A, at first; GOOSE in the SCD file in the IEC61850 model file at the whole station of intelligent substation partly analyzes classification; Comprise: source, characteristic and the version number of AppID, GOID, GOCBRef, DataSet, ConfRev, priority, VLANID, GOOSE message; Extract the characteristic of these parameters, form the model file comparison database;
B, secondly; GOOSE message to substation secondary device to be tested sends is caught; The GOOSE message information that analysis captures; The GOOSE message is located: if in the GOOSE message that captures, have in any three contents and the model file comparison database certain GOOSE data set content consistent, i.e. the GOOSE message that judgement captures is consistent with the characteristic of certain GOOSE data set in the model file comparison database;
C, last; After the GOOSE message that captures is positioned; The GOOSE message information that captures is confirmed to compare with the consistent GOOSE data set information of this GOOSE message that captures one by one with in the model file comparison database; Judge inconsistent information: what relatively back GOOSE parameter attribute was consistent is correct message, otherwise is error message.
