Brief description of the drawings
Fig. 1 is the flow chart of the online check method of electric network model for intelligent grid scheduling system of the invention.
Specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in figure 1, the online check method of electric network model that system is dispatched for intelligent grid of the invention, including it is following
Step,
Step（A）, Model Checking rule base and configuration operating process are set up, comprise the following steps,
（A1）Model Checking rule base is set up, including model real-time check rule and model check rule, the model reality afterwards
Shi Jiaohe rules, including model parameter missing is checked rule, model parameter mistake check rule, model parameter and deviates normal value school
Core rule；The model checks rule afterwards, including the topologically correct property of model checks rule, the relating attribute correctness of model
Check rule, the correctness based on electric power system planning and check rule；
（A2）The process mode of on-time model check, including procedure below are set up,
（1）Process mode is checked in thing, Selection Model real-time check rule is checked in this mode；
（2）Process mode is checked afterwards, and Selection Model is checked rule and checked afterwards in this mode；
（A3）Operating personnel's list of operating maintenance is set up, and is bound with process mode；
Step（B）, the electric network model based on CIM checks the structure of object, is to be mapped as calculating by by model record in data
Realized in CIM electric network models object in machine, including CIM Object Creations class, CIM object properties class, CIM object class, specific table
It is now as follows：
CIM Object Creation classes, such mainly includes CimSchema and CimObjFactory classes.Wherein CimSchema classes master
Be used to reading CIM/RDFS fileinfos, CimObjFactory classes are used to applying calculator memory, establishment specify based on
The electric network model object of CIM/RDFS；CIM object properties classes, such mainly includes CimType classes, CimAttr classes,
CimProperty classes, wherein CimType classes define the CIM class names of electric network model object and the parent and subclass of the CIM classes
Information, CimAttr classes define the CIM attribute informations of electric network model object, and CIM attribute informations dtd--data type definition, such as
INT types, STRING types, many-one association, one-to-many association etc., CimProperty classes are used to define and obtain electric network model pair
The property value of elephant；CIM object class, main class is CimObject classes, and such is the CIM electricity constituted based on the above two class
Implementing for pessimistic concurrency control object, all attribute informations based on CIM of the electric network model object can be obtained by such；
Step（C）, on-time model safeguard check statistical analysis, on-time model provide be based on personnel, the time, three dimensions of model
Modeling statistics analytic function, on-time model is checked by human users' information during check, checks information time, and check
Object, according to personnel, time, in three dimension storages of model scope to database, for subsequent query analysis.
In sum, the online check method of electric network model that system is dispatched for intelligent grid of the invention, by setting up
Model Checking rule base and configuration operating process, automation operation maintenance personnel are entered according to the check rule and flow that pre-define
Row model maintenance works, according to the stage of model maintenance in the pattern of Model Checking, it is online check flow be divided into thing check and
Check afterwards, it is that, to submitting the real-time check for recording to, it is to selected model scope after model is put in storage to check afterwards to be checked in thing
Overall check, it is considered to the complexity of electric network model, in order to improve the efficiency checked afterwards, it is proposed that based on CIM electric network models
The construction method of object is checked, CIM electric network model objects in computer is mapped as by the way that model in data is recorded, so that efficiently
