Description
Technical field
The present invention relates to technical field of power systems, more particularly to a kind of control method of electric power system model versions of data
And device.
Background technology
For extensively, electric power mechanism generally possesses that several can be used and safeguard electrical network structure related data is
System, such as GIS-Geographic Information System (GIS), design system, CAD system, the asset management system, SCADA system, Outage Management Systems
(OMS), Distribution Management System (DMS), and EMS (EMS) etc..
Application and related function module in said system, a part are the homemade utility programs of electric power mechanism, and another
Part is then derived from commercially available into sets of plan, and is customized according to demand for localization.Wherein, electric network model manages this function mould
Block, so that it may so that the data message that electric network model file is included, in the interaction of each system, still keeps and real power network
The uniformity of framework.
Obviously, the key of model management is integrated and synchronous.And in the past, similar function is usually to integrate OMS
With the model data in DMS systems.Rule of thumb, it may also be used for expanding the application category of energy management and control system, example
Such as in OMS/DMS systems, GIS data is further integrated.For example, it can improve generalized information system enters line number toward OMS/DMS systems
According to the ability of migration, so as to reduce the time and spend less energy to establish and dispose an OMS/DMS system.
During most geographical hum patterns are toward integration in configuration of power network, in general, IEC TC57 WG13 can be selected
And the models of WG14 61,968 61970 carry out the Data Integration between system.These are handed over as the grid model data between system
The master pattern for changing foundation is collectively referred to as CIM.These data, can be simultaneously with operation of power networks during preloading
The change of mode, incremental update is carried out to model data.But this Data Integration plant maintenance person works measure larger, work
Make less efficient.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of power system mould
The control method and device of type versions of data, to solve the deficiencies in the prior art.
To achieve the above object, a kind of control method of electric power system model versions of data of the present invention, comprises the following steps：
Step 1: CIM file data is imported into model switching plane MEP；
Step 2: database is arrived into all CIM file data storages importeding into the model switching plane MEP
In, so that system can carry out Version Control to the data in database, the database is divided into three logical model regions, point
It is not：Working model area, full model area and permanet mold area；
Step 3: the working model area in database temporarily stores original CIM file data；
Step 4: the full model area in database is verified and closed to the newly-increased data for being stored in working model
And；
Step 5: in the model switching plane MEP, by platform call used in the retrieval language supported of database
Sentence, the markers attribute included to data in full model area are ranked up and screened, and most its result is sorted out at last, so as to real
The now version management based on timestamp.
In step 3, the working model area storage, and during model imports, by the topological attribute of equipment record
As foundation, the data for being stored in working model area with original from the data message that model file parses are compared, so as to
Analyze the change of electrical network structure increment, and the record mapped that in database.
In step 4, after the full model area is verified and merged to the newly-increased data for being stored in working model, pass through
Permanet mold area persistence in database；
The newly-increased data refer in power system according to changes of operating modes and the equipment alteration data of confirmation；
The verification method is as follows：During model imports, encode these using device coding, assets information and possess
The record attribute of uniqueness, the data for being stored in working model area with original from the data message that model file parses are compared
It is right, result is verified；
The merging method is as follows：The data in working model area are stored in original, comprising unique identification do not occur
This partial data of change is retained；Comprising the data that change of unique identification increased or deleted.
In step 5, data include power system device record, device attribute and device-dependent leading information；
The timestamp occurs to be updated simultaneously in model data version, and more new content includes for it：Version number, version name
The timestamp and annotation that title, types of models, model source, model summary info, version operator, version create.
A kind of control device of electric power system model versions of data of the present invention, including
Model switching plane MEP, for checking and data storage, and the version of checking data is automatically controlled, once data
By Version Control, data can export, by the other applications being employed in program or system (refer to Distribution GIS,
Computer aided design system CAD and DataBase management system) used；
Model switching plane MEP, for carrying out the version pipe based on timestamp to data in the full model area in database
Reason；
Database, it is divided into three logical model regions, is respectively：Working model area, full model area, permanet mold area；
Wherein, working model area, for temporarily storing original CIM file data；
Full model area, for the newly-increased data for being stored in working model to be verified and merged；
Permanet mold area, after the process that model imports terminates, encode these using device coding, assets information and possess only
The record attribute of one property, the data for being stored in working model area with original from the data message that model file parses are compared
It is right, result is verified；And during following data merge, the data in working model area are stored in original, are wrapped
This partial data that the unique identification contained does not change is retained；Comprising the data that change of unique identification
Increased or deleted；Most it is permanently stored at last by the full model area data after checking and merging in permanet mold area.
Above-mentioned working model area stores and analyzes the change of electrical network structure increment, and maps that in database
Record.
After the newly-increased data for being stored in working model area are verified and merged in above-mentioned full model area, pass through database
In permanet mold area persistence.
Above-mentioned model switching plane MEP carries out the version pipe based on timestamp to data in the full model area in database
Reason, wherein timestamp occur to be updated simultaneously in model data version, and more new content includes for it：Version number, version name, mould
The timestamp and annotation that type type, model source, model summary info, version operator, version create.
The beneficial effects of the invention are as follows：
The invention provides a kind of database, the database is divided into multiple logic regions, and the logic region is included extremely
A few working model logic region and a permanet mold logic region.Data are directed in working model logic region
Meanwhile the version information using timestamp as most basic key element is associated with the data imported.Then by the data inputted and
Related version information is stored in permanet mold logic region.Attendant's workload is alleviated, improves operating efficiency.
Design, concrete structure and the caused technique effect of the present invention are described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
