Integrated Modeling between Smart Substation and Dispatch Automation System

Abstract – Based on technical supporting systems for smart grid dispatch and smart substation system and according to the functional demand of dispatch master station to the substation, an integrated modeling scheme for coordinated sharing of models/images and seamless communication between dispatch master station and smart substation is proposed, by which practicable converting rules between IEC 61850-based model and IEC 61970-based model are drafted; a unified data model-based mapping approach for IEC 61850-based model and IEC 61970-based model is put forward; by means of splitting/merging technique of models and self-converting technique of Ids of graphs and so on, the integrated modeling between dispatch master station and smart substation is implemented; utilizing message bus service of dispatch master station and manufacturing message specification (MMS) protocol stack, the IEC 61850 protocol-based communication at dispatch master station side is attained, thus the coordinated sharing of models/imag...
