The Integration Of EMS And WAMS Is Based On IEC 61970 Standard

It's essential to apply the Energy management system (EMS) and Wide Area Mesurement system into modern electric power system. At present, This two systems were developement independantly, therefore, in the operation process, the work staff have to both master and maintain this two systems, it will cost much human resources and material resources. Also, many subsystems were heterogeneous system that caused serious impact for data communication and information sharing between different databases. IEC61970 seiris standard has been defined common information model for electric power equipment that lay an important model foundation to data sharing between different subsystem and make the intergration of heterogeneous system are possilbe.This thesis work firstly proposed an intergrated architectur design principle for EMS and WAMS based on analyzation of CIM and data flow. This design principle were focus on unified platform, data structure and application function. Moreover, analyzed the model of EMS and WAMS. abstracted and established some new model class which included the Time synchronization device class, Phase measurement device class and PMU class by using UML, and estabished the unified information model for EMS and WAMS by analyzation of chrateristic of EMS and WAMS. At the last, implenmented this unified information model, completed the convertion from UML model to CIM RDF schema format, provided an unified format for different application system, implenmented the access of common database based on unified model of EMS and WAMS by means of using the Web Service method.
