The distributed object technology and its application in the next generation of a power dispatching automation system are introduced. Standard IEC 61970 is to found common information model (CIM) for the power system objects and to form component interface specifications (CIS) for logical information exchanges among all applications. Standard IEC 61970 is the theoretical basis of data models and distributed object technology is the technology guarantee of implementing this system. Each application, each service or each sub-system can be described as one or more components. All components are interconnected by an integration framework, which is composed of object request broker (ORB) bus, namely the core of common object request broker architecture (CORBA). In this paper, the background of developing a next generation of a power dispatching automation system complying with Standard IEC 61970 is reviewed. On the basis of a lot of testing data about CORBA performance, the feasibility of adopting CORBA-based distributed object technology is discussed. Constructing integration framework of the system and encapsulating the existing applications or programs are two main methods about CORBA applications. Lastly, the whole system structure and its design scheme of the dispatching automation system are presented and analyzed.
