Design of Dual-Encoding System for Distribution Network Based on Service Oriented Architecture

One of the development direction of smart distribution network is to increase the integration of information in dispatching center and implement efficient data exchange and sharing,and information encoding is one of the important supporting technique for the integration.To meet the demands of distribution equipment management and dispatching operation,based on the research on applying the information integration to distribution system by service-oriented architecture(SOA) a dual-encoding system,i.e.,the equipment encoding and dispatch encoding,is proposed and the concepts of virtual transfomation substation and virtual switching substation are led in to carry out hierarchical partitioning of distribution network model.The concept and implementation of mutual mapping between the two sets of codes are put forward,and the accuracy of the encoding is ensured by self-checking.Finally,the development direction of coding technique in future is prospected.
