Research On Data Access Of Active Distribution Network System Based On WCF Technology

In order to maximize the initiative of active distribution network and effectively realize the sharing of data resources in active distribution network,shielded power management system(EMS),power production management system(PMS),marketing management system(EPM)and dispatching management system(operation management system)are adopted.for other heterogeneous databases in the five major application systems bring about differences,to solve the problem of unified access,access and integration of the active distribution network to the databases of the five major power application systems.Based on the SOA architecture and object relationship mapping technology,combined with the component model of data access,this paper applies WCF encapsulation technology to realize the design and implementation of data access for five major application systems,so as to realize the efficient operation of active distribution network system?Mainly carry out the following aspects of work:1.The existing problems in the construction of active distribution network system are analyzed,especially the problem of data interaction with five major power application systems,and then the idea and solution of data access component development are put forward?2.Establish the data access component model of active distribution network,and establish the implementation method,framework and technology of active distribution network data access component?3.Design and implement the data access component model,define the access interfaces of five major power application systems using WCF technology,and elaborate the data access of five major power application systems respectively?4.Using WCF technology,the host hosting of data access service in active distribution network system and the management and implementation of communication node connections in five major application systems are realized?5.An application example of Active Distribution Network Data Component Access(EMS)power management system is introduced.
