Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present invention sets up unified model operation management center, and any model maintenance operation of dispatching center is all undertaken by this model Operation and Maintenance Center, can realize easily source maintenance and the whole network of electric network model and share, and forms the large electric network model that a whole network is unified.
Integrated Model management is the full electric network model of safeguarding unity with the target of safeguarding, from model memory technology angle, Integrated Model is safeguarded and is mainly divided into centralized stores pattern and distributed store pattern.The memory module that the present invention adopts two kinds of memory modules to mix.Wherein centralized stores mode scheme figure as shown in Figure 1, the centralized and unified storage of whole electric network model is carried out at the whole network operation management center, network model and the real time data of remote maintenance oneself administration on the computing node of oneself of each dispatching center, or the maintainer at operation maintenance center is by cloud computing platform maintaining network model, realize unified storage and the centralized maintenance of whole electric network model, guarantee the uniqueness of the whole network model, and unified model share and access service mechanism is provided.Distributed store conceptual scheme as shown in Figure 2, distributed store pattern model file is kept at dispatching center's node of current maintenance, each dispatching center safeguards local to one's name network model and the real time data of compass of competency as required, the model access services providing according to service bus, towards the whole network update service that supplies a model, realize the unified logic of the whole network model.
Mix memory module: the whole network model operation management center has the large electric network model of a unification, the electric network model that dispatching systems at different levels are used is stored in this locality as the subset of the whole network model, carrying out interlock in real time with the whole network model upgrades, each dispatching center provides model raw data at the corresponding levels, and passes to model operation management center with CIM/E in form.Specific as follows:
1) model subregion is safeguarded with interlock and is upgraded:
Each regional power grid regulation and control center can regulate and control in central dispatching automated system one's respective area model is safeguarded respectively in the corresponding levels.Regional model after safeguarding is uploaded to model maintenance node, and this node can be unified splicing to model and upgrade with interlock, forms up-to-date large pessimistic concurrency control.
2) large pessimistic concurrency control is unified safeguards and synchronizes renewal:
In addition, also can to large pessimistic concurrency control, carry out the maintenance of univesral distribution formula at model maintenance node, then the model of safeguarding is synchronously updated to distributed data base, and be published to each regional control center.
These two kinds of modes are freely selected by client, and how the interlock of model real-time synchronization is upgraded.
The distributed maintenance of electric network model provided by the invention and overall shared system figure as shown in Figure 3, comprise the regional dispatching center, the whole network model operation management center, the many edition management systems of model and the server that communicate successively; And described regional dispatching center is initiated subscribe request by client end interface to server.
The whole network model operation management center adopts model maintenance node, described model maintenance node comprises that maintenance merges module and historical models is browsed node, and described model maintenance and merging module are used for model splicing, model modification maintenance, model is synchronous and historical models recovers; Described historical models is browsed node for browsing and check old version model.
Model maintenance node needs installation database, completes the functional steps such as splicing, warehouse-in of model.
1. model modification is safeguarded: mainly comprise: database model table is revised (model table tries not to revise, if really need to revise, must accomplish that the whole network is unified) and model data is revised.
2. model is synchronous: model maintenance node is except offering the whole network model after merging historical models memory node, the model of revising after safeguarding can also be exported as to CIME file, offer memory node, while guaranteeing that model changes or upgrades, memory node can obtain up-to-date model file.
3. historical models recovers: generally, model maintenance node sends to model memory node by the model of safeguarding, but once model in model maintenance node goes wrong and (makes mistakes as revised, or generation maloperation etc.), can send request to model memory node, obtain the updated model that memory node is preserved, and it is synchronously updated to model maintenance node.If want the model in Maintenance Point to return to certain version of historical models, also can send corresponding request to memory node.
The many edition management systems of model are included in distributed data base, support release maintenance, user management, and the version that supplies a model detects and accesses, the many edition management systems of described model comprise model memory node, and described model memory node is for storing old version model, externally historical models inquiry being provided and issuing the updated model after maintenance by area.Server is used for controlling users' at different levels access rights, and authority is managed.
The present invention also provides the implementation method of the distributed maintenance of a kind of electric network model and overall shared system, and its process flow diagram as shown in Figure 4, comprises the steps:
(1) dispatching center, each department provides the file of MODEL C IM/E separately, and the model maintenance node of dispatching center completes the work such as border maintenance, splicing and equivalent merging of model, forms the whole network MODEL C IM/E file.
(2) and with the version submit operation of the whole network MODEL C IM/E file trigger model, deposit the whole network model of redaction in distributed data base, and form new version.The many edition management systems of model are supported release maintenance, user management, and the version that supplies a model detects and access function.
(3) dispatching centers at different levels initiate subscribe request by client end interface, server controls users' at different levels access rights, and by the many edition management systems of model, issued models at different levels and the substation model of corresponding CIM/E file layout.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although the present invention is had been described in detail with reference to above-described embodiment, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present invention, and do not depart from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of claim scope of the present invention.
