Abstract: On the basis of the requirement of real-time data transmission of a distributed power supervisory control system, this paper analyzes some different styles of implementation and proposes a real-time data transmission model implemented by CORBA notification service. Providing filter and QoS control policy, the proposed model is flexible. Furthermore, it can perform reliable and real-time data transmission.
