SCD can be used as the source of the model of scheduling station, is equally also the source of the model of automatic monitoring system of transformer substation.but in above-mentioned document, do not set forth the SCD model when changing, how does this process? when transformer station's reorganization and expansion, perhaps in debugging, later stage, various parameter configuration, debugging has all been done in a lot of situations, if the SCD model content changes (being referred to as the SCD iteration), supervisory control system should import the SCD file again, but this process can not be simply again definitely the process of " import-〉 generating database model ", no side, after supervisory control system imports model, the database configuration of before doing, debugging will be done one time again, this has been operable to subversive modification, in Practical Project is implemented, impracticable like this.Needing to solve the problem that increment SCD imports, is also the iterative processing of SCD.

Summary of the invention

A kind of when the present invention proposes the SCD of transformer station model and automatically changing SCD iterative processing method, for the monitoring system of electric substation based on IEC61850, when employing is changed generation supervisory control system transaction module automatically from full station SCD model, the processing method of SCD iteration is proposed.After avoiding SCD to change, the system parameters that whole coverings are configured, debug when guaranteeing that the SCD iteration imports, reduces to minimum to the disturbance of system.

The present invention adopts following technical scheme for solving its technical problem:

A kind of when SCD of transformer station model is changed automatically SCD iterative processing method comprises the steps:

1) in the SCD model file, set up the description of increment content;

2) set up SCD change model in supervisory control system, the key message during the last importing of record model;

3) during model conversion, analyze the object of change, then carry out the iterative processing of increment content;

4) after model imports end, from the anti-SCD model of looking into of monitoring model, with the no data deletion of redundancy.

In described step 1), the description of increment content comprises:

For secondary device, record the variation of IED, comprise Add, Update, Delete, the Rename operation of IED;

For primary equipment, the variation of intra-record slack byte (Bay) comprises Add, Update, Rename, the Delete operation of interval (Bay);

For the variation of transformer station (STA), electric pressure (VOL), communications setting (COM), all record their Add, Update, Rename, Delete operation;

For SCD modification each time, all record its version number.

Described step 2) comprising:

The table name that is uncovered when 1. being recorded in iteration and field name thereof;

2. set up the SCD version information, the last SCD version information that imports of record, to the effect that: SCD version number;

3. set up the SCD spacing sheet, record all the interval lists when importing last time, comprise name, the descriptor at interval;

4. set up interval IED table, name, the description of recording the IED of each headway management when importing last time;

5. set up interval LN table, record name, the instance number information of the LN of each the interval association when importing last time, affiliated IED;

6. set up the IED data set table, record the name of the data set that each IED when importing last time comprises;

7. set up the object data set table, record the name of each data set when importing last time, every object information, affiliated IED;

8. set up data set RCB table, record the name information of each the data set RCB when importing last time.

The object of analyzing change in described step 3) comprises:

A) the variation object of primary equipment according to the description of increment SCD content, determines to change object;

B) for secondary device, as follows object is determined to change in arbitrary interval:

1. the interval object before and after changing according to SCD analyzes the interval object in the change model;

2. analyze in SCD LN related under this interval, and analyze the LN of SCD management last time from the change model, determine the LN object that changes;

3. for each change LN, possible former because:

A) the LN name has changed, and as being only that variation has occured for instance number and prefix, being considered as name and changing, and is one and upgrades operation.Type changes, and is deletion and newly-built operation;

B) DO under LN has become, and has been considered as a signal object newly-built;

C) according to the data set table of IED, determine the variation list object of LN.

In described step 3), the iterative processing of increment content is as follows:

1. operational same record, major key changes, and human-edited's field information will keep; When the prosthetic edit field, need not to pay close attention to, directly cleaning gets final product;

2. major key is as the external key of another table or implicit association, and related variation will be processed, and adjusts field when prosthetic, need not to pay close attention to, and directly cleaning gets final product;

3. the association of the LN deletion action of SCD or first and second equipment changes, or some record that causes becomes discarded record, does corresponding operation;

The association of first and second equipment changes the following several situation that is divided into:

A) equipment variations of the LN association of certain IED, transfer to equipment B from device A, is operating as: at first this LN under sweep equipment A is related, then adds a LN under equipment B, and this LN association is come;

B) after the LN knot removal that certain equipment is corresponding, the LN that has added other types is related: at first this LN under sweep equipment A is related, then adds a LN under equipment B, and this LN association is come;

C) the LN node content of two primary equipment associations exchanges, and is equivalent to implication and changes, and the constraint of importing is no problem;

4. by the artificial record that adds, can not be cleaned out because of importing;

5. record the interference that is not subjected to above-mentioned any situation in table, need not special processing, before importing, directly remove all records, then add getting final product.

Beneficial effect of the present invention is as follows:

By the processing of SCD iteration, when the SCD content changing, do not need that subversive whole covering is debugged, adjusted parameter, avoid therefore and the system's hidden danger that produces.Make SCD model automatic mapping reach practical to the mode of Monitor and Control System.

Embodiment

Below in conjunction with accompanying drawing, the invention is described in further details.

The foundation of increment content:

The increment content of setting up the SCD model file is the first step of SCD iterative processing, and the SCD file itself is based on the XML form, utilizes under History the Hitem label to set up change record.The implication that increases change is as shown in the table.

For example, a SCD increment content record is as follows:

＜Hitem version=" 1 " revision=" 00 " what=" BAY Add interval 1 " when=" 2010-12-23 03:20:28 "/〉

＜Hitem version=" 1 " revision=" 01 " what=" BAY Rename interval 1 10 mothers measurements " when=" 2010-12-23 03:20:44 "/〉

＜Hitem version=" 1 " revision=" 02 " what=" BAY Rename 10 mothers are measured 10 mother when=" 2010-12-23 03:21:43 "/

＜Hitem version=" 1 " revision=" 03 " what=" BAY Update function 1 when=" 2010-12-23 03:21:45 "/

＜Hitem version=" 1 " revision=" 04 " what=" BAY Update measures when=" 2010-12-23 03:22:01 "/

<Hitem?version="1"?revision="05"?what="BAY?Update?None/.MMXU13:"?when="2010-12-23?03:22:08"/>

<Hitem?version="1"?revision="06"?what="BAY?Update?None/.MMXU14:"?when="2010-12-23?03:22:35"?/>

</History>

The lower Column Properties that the primary information change will be filled the Hitem label occurs in SCD:

The major release of version:SCD file increases progressively successively from 1, and step-length is 1, and the change of this property value is driven by the revision value, and after revision became 99 from 00, change again will be to the version carry, and the revision involution is 00, circulation successively;

The minor release/point release of revision:SCD file once increases progressively from 00, and step-length is 1, maximum 99, and each increment modification information correspondence a minor release/point release;

When: the time that the increment change occurs, the time of confirming with change is as the criterion;

What: modification information content.

Information format: InfoType+OperType+Name+[Oldname]

Wherein+corresponding space;

The InfoType corresponding types has IED, BAY, STA, VOL;

The OperType correspondence Add, Delete, Update, Rename;

The Name correspondence the current title of type;

Oldname only has Rename operation just to exist, corresponding the front title of Type Change;

The record format of communication configuration is different, and information format is as follows:

InfoType+OperType+SubnetworkName+Iedname+Appname

Wherein+corresponding space;

The InfoType corresponding types is COM;

The OperType correspondence Add, Delete, Update;

The SubnetworkName correspondence MMS subnet title;

The Iedname correspondence the IED title;

The Appname correspondence the title of accessing points;

What Content of Communication changed gives an example:

<Hitem?version="1"?revision="01"?what="IED?Add?UDM502-4"?when="2009-12-07?10:12:35"/>

<Hitem?version="1"?revision="02"?what="IED?Rename?UDM502?DUM502-4"?when="2009-12-07?10:16:04"?/>

<Hitem?version="1"?revision="03"?what="COM?Add?MMS?UDM502?S1"when="2009-12-07?11:01:23"/>

Supervisory control system is set up the change model:

Provide at the SCD model file on the basis of some SCD incremental records, also will set up additional importing record in supervisory control system, when being convenient to increment SCD importing file, analyze the increment content, as shown in Figure 1.

1) the SCD model file comprise whole transformer station once, secondary model, these contents are subsets of the whole parameter of supervisory control system.Supervisory control system also has other parameter except the SCD content that imports.After importing the SCD model, the supervisory control system parameter is to need artificial the adjustment a bit.Designed a form, which field of the concrete table of record when the SCD iteration, does not allow to cover for this reason.Such as: " description " attribute of primary equipment, this information is arranged in the SCD model file, but after importing the SCD file, supervisory control system sometimes as required, the description of certain equipment of manual amendment, the description of revising in supervisory control system can't be synchronized to the SCD file, like this, just can not describe the description that existed in the covering supervisory control system with the primary equipment of SCD when import SCD next time, otherwise the adjustment in supervisory control system has just been lost.

2) set up SCD version information table, the SCD version number when preserving the last the importing.Be convenient to whether change from highest level comparison SCD content when importing the SCD model.If system imports the SCD model for the first time, do full importing.If SCD version number is lower than existing version number, prompting is all removed former data again with the full mode that imports.All the other situations are just used the iteration lead-in mode.

3) set up the SCD spacing sheet, record all the interval lists when importing last time, content comprises: the name at interval, the description at interval.

4) set up the LN table, record LN name, instance number information, affiliated IED information when importing last time.

5) set up the IED data set table, record the name information of the data set of each IED when importing last time.

6) set up the object data set table, record name, each object information of the data set that each data set when importing last time comprises.

7) set up data set RCB table, record the information of each data set control block that imported last time.

Iterative processing

At first determine to change object.

1) the variation object of primary equipment according to the description of increment SCD content, determines to change object.

2) for secondary device, determine as follows to change object (to arbitrary interval):

3) change the interval object of front and back according to SCD, find the interval object in the change model.

4) analyze in SCD LN related under this interval, and analyze the LN of SCD management last time from the change model, determine the LN object that changes.

5) for each change LN, possible former because:

6) the LN name has changed, and as being only that variation has occured for instance number and prefix, being considered as name and changing, and is one and upgrades operation.If type changes, be deletion and newly-built operation.

7) DO under LN has become, and has been considered as an object newly-built.

8) according to the data set table of IED, determine the variation list object of LN.

After having determined the variation object, during concrete operation, adopt following alternative manner:

Operational same record, major key changes, and human-edited's field information will keep; If the prosthetic edit field need not to pay close attention to, directly cleaning gets final product.As shown in Figure 2:

If Table1 table, EDIT_INFO, IMPORT_INFO field are when initial the importing, all import initialize by SCD, but EDIT_INFO field, may be by artificial adjustment between system's operation, limber up period, and this field is to need to keep, and when the SCD iteration imports, can not cover the content of this field.

If the Table2 table, all fields import by SCD, and can not revise between system's operation, limber up period, directly this table are emptied when the SCD iteration imports, and then import to get final product.

Major key is as the external key (or implicit association) of another table, and related variation will be processed; If prosthetic is adjusted field, need not to pay close attention to, directly cleaning gets final product;

As shown in Figure 3, if Table2 shows to import because all information are from SCD, do not have the information of operation, debug phase modification, when the SCD iteration imports, directly the Table2 table is emptied, then, importing gets final product.

As shown in Figure 4, if there is the EDIT_INFO field that may adjust between operation, limber up period in the Table2 table, at this moment, need to upgrade major key and IMPORT_INFO field information.

The LN deletion action of SCD or the association of a secondary device change, or some record that causes becomes discarded record, do corresponding operation.

As: deleted certain equipment, deleted LN, edited LN etc., all can cause some protocol failure, wherein the association of a secondary device changes the following several situation that is divided into:

The equipment variations of the LN association of certain IED is transferred to equipment B from device A, is operating as: at first this LN under sweep equipment A is related, then adds a LN under equipment B, and this LN association is come;

After LN knot removal corresponding to certain equipment, added the LN related (processing mode is the same) of other types;

The LN node content of two primary equipment associations exchanges (be equivalent to implication and change, the constraint of importing is no problem);

By the record of artificial interpolation, can not be cleaned out because of importing;

If in table, record is not subjected to the interference of above-mentioned any situation, need not special processing, before importing, directly remove all records, then add getting final product.
