Description

The describing method of the IEC61850 model file based on CIM/E

Technical field

The present invention relates to power automation technical field, be specifically related to a kind of based on CIM/E'sThe describing method of IEC61850 model file.

Background technology

Along with the development of intelligent grid technology, electric substation automation system and dispatching patcherContact increasingly closely, both integral fusion are one of important directions of current power System Development.But current aspect the modeling of electric substation automation system and dispatching patcher, transformer station's end is generalAll over adopting IEC61850 model tormulation mode, the formalized description work of semantic model is by power transformationThe configuration language SCL that stands completes; And IEC61970 standard is followed in dispatching terminal modeling, adopt baseIn the model description method of CIM/XML or CIM/E. Therefore, transformer station's end and dispatching terminalModel the disunity set up, and indigestion each other, thus, bring model to be total toEnjoy, hindered both integral fusion, thereby suppressed technological progress and the intelligence of power systemThe development of electrical network.

Substation configuration description language SCL be IEC61850 ?be used in 6 standards describing and communicating by letterRelevant IED structure and parameter, communication system architecture, switch gap functional structure and they itBetween relation, in order to realize versatility, self-described, and the object that can expand arbitrarily, SCLThe grammatical norm of expandable mark language XML followed in language on grammer, by defining eightXMLSchema file, strict regulations the tree-shaped layers of all self-described documents taking it as standardThe full details of aggregated(particle) structure. In actual substation project application, the power transformation of SCL language descriptionThe model file of standing meets the actual demand of engineering application completely, but along with intelligent substation engineering is builtIf carry out in a deep going way, the transformer station model file of SCL language description is increasingly huge, thus, alsoThe system processing speed of bringing is slow, object granularity is too little, model file redundancy too much,Structure is too complicated, be not easy to the series of problems such as engineering staff's direct reading.

In recent years, transformer station's end and the skimble-scamble problem of dispatching terminal model obtain people's height graduallyDegree is paid attention to, and both at home and abroad research institution has proposed multiple solution, comprise direct unified model,Public semantic model, Model Mapping, System Seamless Communication Architecture etc. But, all exist separately notFoot, specific as follows,

(1) directly unified model is by formulating new unified standard, can meet IEC simultaneously61970 and IEC61850 modeling demand, its shortcoming is existing standard to change larger,Implement very difficult;

(2) public semantic model is to merge IEC61850 on IEC61970CIM/XML basisModel, new model can be understood IEC61970 and IEC61850 standard simultaneously, but still at presentIn conceptual phase, there are no practical application;

(3) Model Mapping is on the basis that existing standard is understood, and increases Model Mapping and joinsPut file, by " translation " function of this configuration file, realize the mutual of two kinds of master patternsConversion;

(4) System Seamless Communication Architecture is similar to Model Mapping, and this scheme " is turned over configuration fileTranslate " function is placed in middle-agent's gateway, transformer station's end and dispatching terminal by with middle-agent's netThe communication of closing, implementation model information mutual.

And (4) two schemes (3), though there are some pilots application, main or IEC61850Model conversion is IEC61970CIM/XML model, consider these two kinds of file formats all based onThe syntactic structure of XML, thus there is the efficiency not high problem described, along with intelligent substation notDisconnected development, transformer station model file is increasingly sophisticated, and the process of Model Mapping conversion also will constantly changeEnter perfectly, the workload of exploitation is huge, and follow-up maintenance work is also difficult to continue follow-up.

CIM/E language is the new main website end modeling language that Guo Tiao center is tried hard to recommend in recent years, at present,Domestic existing many dispatching patchers can be resolved this language institute's established model and generate system number separatelyAccording to storehouse, CIM/E language design is followed simply, efficiency, practicality, object, relation, name sixLarge principle, can be used for describing transformer station model in theory completely. Domestic, existing some mechanismsPropose relevant solution, mainly concentrate on Model Mapping, the aspects such as standard expansion. ConsiderTo IEC61850 ?in 6 standards, the description that XMLSchema file is detailed the grammer of SCL,Therefore, how based on CIM/E language, IEC61850SCLSchema file to be described again,Realize CIM/E language description transformer station model and transformer station's end and dispatching terminal model and merge, beThe current problem that needs solution.
