Description
Technical field
The invention belongs to technical field of electric power automation, be specifically related to a kind of method that CC2000 model conversion imports D5000 system.
Background technology
Traditional electric power monitoring system and infosystem are all set up independently information model according to oneself specific demand, when different systems carries out message exchange, need to translate model or change, unmatched models such as between system A and system B, when carrying out exchanges data so between system a and systemb, the data of system A are after system B, and the data model translation of system A first will be become the model corresponding to self by system B, and then by data to entering in system B.If need the system of message exchange more than two, then carrying out information sharing between different system just needs, through a large amount of model translation or conversion, to cause the wasting of resources.Therefore International Electrotechnical Commission IEC defines a kind of electric system Common Information Model CIM (CommonInformation Model).Common Information Model CIM is the important tool of electric power enterprise application integration, it comprises public class, attribute, relation etc., its class (Class) and object (Object) are abstract, may be used for many electric system application, it is the soul of logic data structure, definable information exchange model.
Common Information Model CIM is unified, but different producers, different systems are different to its understanding, the data layout supported also is had any different, and the data layout that in the present invention, CC2000 supports better is the data layout that CIM/XML, D5000 support better is CIM/E.
XML data document format comprises preamble (prolog) and root element (root element) two requisite parts.
Preamble include to the version of the XML standard that document is followed and use the statement of coding, preamble is very simple, as <? xml version=" 1.0 " encoding=" UTF ?8 "? >;
Root element contains the actual content of XML document, and these contents are included within beginning and end mark.
Element (element) is included in the container between beginning and end mark.The name of beginning label definition element also comprises any attribute of this element.In example such as, Class is masurium, and ID is its attribute.
<rdfs:Class rdf:ID＝"Bay">
The end mark of this element is </rdfs:Class>.
ID attribute quotes other node elements in CIM RDF Schema document for enabling Class element.The element of ID=" Bay " can be quoted by other elements, as " #Bay " by the mode adding No. # before this property value.
Because CIM/XML language exists some problems, as described, efficiency is too low, data importing/derivation speed is slower, therefore, on the basis of inheriting XML language advantage, creates a kind of new and effective Language for Electric Power System Model Description---E language.
The basic function of E language uses 4 conventional sign (<, >, @, #), support 3 kinds of describing modes (horizontal tabular form, single-column type, row), there is stronger descriptive power, most of data model and data interchange format in electric system can have been described efficiently, implement fairly simple.The expanding function of E language inherits CIM overall framework, inherits OO thought, inherits XML dirigibility, inherits the high-level efficiency of facing relation technology, inherits the convenience of Excel, and representation function is very powerful.
Because bilingual form is different, two system CC2000 and D5000 communicate each other and carry out translating and changing with regard to needs.
