Description
Technical field
The present invention relates to a kind of based on the incorporate intelligent substation modelling of CAD artwork method.
Background technology
The modeling tool aspect of intelligent substation is mainly paid close attention in intelligent substation design at present, is main task with modeling results such as input, the SCD, the ICD that export IEC61850, CID only.These files mainly use for the engineering staff of IED producer, both do not consider to provide comprehensive intelligent substation engineering design result, do not consider design drawing and combining of IEC61850-SCL etc. again.Because designing unit does not have suitable or available design means, engineering design only limits to finish the degree of hardwire design, needed intelligent apparatus functional configuration of engineering construction stage, communicate configuration and relevant design data can not be provided, consequently cause to participate in, to decide through consultation voluntarily the function communicate configuration of logic aspect by a large amount of research and development personnel and constantly revise software code at the scene and debugging repeatedly that in the engineering construction stage of intelligent substation process of construction is very lack of standardization and the cycle is very long at present; Because logical layer function communicate configuration is definition voluntarily between the producer, its standardization and semantic consistance also can not get guaranteeing, have limited the interoperability performance of secondary device greatly, have increased the cost of intelligent substation operation maintenance and reorganization and expansion work.
In sum, the engineering design technology of conventional substation can not satisfy the needs of intelligent substation, and the design system and the solution of intelligent substation are also very immature at present.Publication number is that the patent " based on the graphical intelligent substation modelling method of CAD " of CN101989312A need propose a kind of graphical model method for designing based on CAD at intelligent substation design, this method is described the model of IEC61850 by pel piece attribute, and the pel piece that has an IEC61850 extended attribute by drafting is finished the design of intelligent substation system; Then, generate the XML database of describing the IEC61850 model, from the XML database, derive IEC61850 model description file SCD by pel piece attribute.
Publication number is the subject matter that the patent of CN101989312A exists: because pel piece attribute has bidimensionality, and the IEC61850 model has the multidimensional characteristic, as describe the IEC61850 model of multi-dimensional nature with the pel piece of two-dimensional characteristics, must earlier the IEC61850 model be divided into the pel piece that several have two-dimensional characteristics, and needs are expressed the mutual relationship between these pel pieces, this expression causes the figure line complicated unusually, and being the designer mostly, these complicated lines do not need to be concerned about, therefore cause whole design operation inconvenience, thereby reduced designer's operating efficiency.
Summary of the invention
For remedying the deficiencies in the prior art, the present invention proposes a kind of based on the incorporate intelligent substation modelling of CAD artwork method, this method directly use W3C's " generic resource describing framework RDF " the IEC61850 model is described, set up the mapping relations between pel and the rdf model, pass through graphing, realization is to the synchronous operation in rdf model storehouse, to finish the design of intelligent substation system.Then, generate IEC61850 model description file SCD by the rdf model storehouse.The incorporate realization design of this artwork is to be core with the model, and figure is represented for model in visibleization, so just can guarantee the consistance of figure and model.
For achieving the above object, the present invention adopts following technical scheme:
Based on the incorporate intelligent substation modelling of CAD artwork method, the performing step of this method is as follows:
A. define model RDF Schema: adopt the form identical to describe the IEC61850 model with RDF with IEC61970 CIM, provide the RDF Schema of IEC61850 model, to determine the structure of IEC61850 model object, the structure of described IEC61850 model object comprises model class, the incidence relation between model class attribute and the model class;
B. define primitive types in AutoCAD: by increase attribute in primitive types, the mapping relations of description and rdf model are to set up the one-to-one relationship of primitive types and model class;
C. graphical modeling: draw the example of each primitive types, set up incidence relation between its model object, generate the model object data at full station when finishing the design of whole transformer station by the line between each primitive types example;
D. according to IEC61850-6 to SCL syntax and semantics regulation, generate SCD, CID model file and be used to the form of the logical relation of constructing, debugging according to the model object data at full station.
In the described steps A, among the described step C, the performing step of graphical modeling is as follows:
1) on the AutoCAD drawing, draws the pel of primary equipment correspondence, generate the model object of primary equipment correspondence simultaneously, by drawing the modification that a time main wiring diagram is finished the primary system model object synchronously;
2) import the ICD file and set up corresponding different types of IED model data;
3) draw the IED pel on the AutoCAD drawing, system sets up the synchronized relation of IED model data and IED pel automatically; Draw the annexation between the IED pel simultaneously, obtain network service figure of transformer station and virtual secondary circuit figure, finish the synchronous modification of electrical secondary system model object automatically;
4) finish the design of whole transformer station, generate the model object data at full station simultaneously.
Beneficial effect of the present invention:
1) the present invention is based on the integrated secondary circuit design of finishing intelligent substation synchronously of artwork generates with model file, each pel is corresponding data object behind, by the graphic operation model, guaranteed the consistance of secondary circuit design, solved the not enough problem of current intelligent substation projected depth with model file.
2) finish and reach the designer who does not understand 61850 ins and outs and can finish transformer station model design.The designer need not be concerned about the model file interior details when the design secondary circuit, only need finish the secondary circuit design according to the design of traditional transformer station and can finish the model file generation synchronously.
3) role of designing unit in the intelligent substation building-up work and function have been strengthened: provide secondary communicate by letter integrated ability and the means of getting involved to design department, from the source, the secondary communication process of transformer station is controlled, be beneficial to the standardization and the standardization of the integrated work of transformer station secondary system, also be beneficial to the coordination that mode work is installed, be more conducive to the renewal of enlarging, transformation and the equipment of substation project from now on.
4) increased the visuality that substation operation is safeguarded: the SCD file that integrator provides has comprised the integrated information of total system, but relevant information is not simple and clear, for equipment installation and operation maintainer, the information of Network Transmission is opaque, the Installation and Debugging and the operation maintenance of the equipment of giving have brought great inconvenience, and the empty secondary circuit design of graphical design can be expressed the information transmission between the equipment in traditional secondary circuit mode.
5) in conjunction with traditional design personnel's custom, the graphical loop design of carrying out under based on the AutoCAD platform designer's operation of being more convenient for.
6) because primary system uses IEC61970 CIM model description model, can derive the data of supporting other application, increase the opening of method.
