In view of the independent development mode of the traditional dispatching automation system and the substation automation system

a service architecture based integrated solution for the communication between the dispatching system and the substation system is proposed. In consideration of the communication system between the dispatching center and the substation at the present stage

an investigation is launched from three aspects: the communication protocol

the substation basic platform

model and data. The service interaction between the dispatching center and the substation is achieved by adopting the service-based protocol. The dispatching center can get model

data and document from the substation by establishing an open substation base platform. According to the interaction model and the standardization of data between the dispatching center and the substation

the published models and data technical specifications are combed. This paper also proposes the transformation of the classified transaction model and the standardized data access frame

making the interaction even more flexible. Finally

the overall technical framework of the integration of the dispatching center and the substation is given.
