Integrated Modeling of Distribution Terminals for Distribution Internet of Things
In allusion to the problems that the current distribu-tion terminal information model based on IEC61850 is not enough to describe and cover the distribution Internet of Things(DIoT),the development oriented to the terminal micro applica-tion for the model is not considered,and there are shortcom-ings in flexible extension of functions for the model,an integ-rated information model of distribution terminals for DIoT was proposed.In this model,IEC61850,CIM and object model were integrated and expanded,and four top level ontologies of object,data,device and service were established by means of flat model hierarchy and ontology-based model abstraction method,which is suitable for distribution terminals plug and play under large-scale access situation and equipment informa-tion model interaction between cloud master station and termin-als.Also,this model helps to reduce the complexity of informa-tion interaction management between terminal micro-applica-tions,and to realize the integration function of distribution ter-minals,which can fully support the digital transformation of current distribution terminals.
