Panoramic Information Modeling And Model Application Of Power Transmission And Transformation Equipments

Currently, the scale of power grid increased by leaps and bounds, added withobjective harsh environment.There is a great challenge to the security of power grid.Asset lifecycle management system can improve the management level of the electricequipment business.While, the analysis panoramic model of power transmission andsubstation equipment, which has ability of solving the problem of "islands ofinformation" in process of the system construction, repeatation of the modeling,incomprehensive information. At present, domestic and foreign research on thepropagation of the CIM model is relatively much, but in view of the model validation,they are seldom involved. Therefore, theory of Petri Net is used to test extended model.The work of this paper is mainly focused on:Firstly, difference between the power enterprise information integration methodshas been compared.Then this paper analyzes the needs of metadata integrationtechnology according to the full life cycle management system,studies establishingmethods and expanded principles of public information model in the power systemwith referring to IEC61970and IEC61968CIM standards and other power industrynorms.In accordance with the principles and methods,this paper also extends the CIMmodel by Rational Rose software.The panoramic information model constructs basedon UML,which mainly includes four aspects, namely, the basic model of the assets,the working model of assets, the model of on-line monitoring, the model of publicinformation and the model of service.Subsequently, this paper studies in-depth validation problem of the informationmodel, discusses the mapping methods of an extended information model to a Petrinet. Coveraged Tree and the Emergence Sequence theorys are used to verify the netstructure and semantics with the instance of activity diagram verification, whichincludes of electricity estimated system and equipment replacement applicationsystem, to ensure the validity of the model.Furthermore, this paper researches relatedtechnology of model applications, and discusses the field deployment of panoramicinformation model, lastly design a specific application program of this model.
