The Study of Data Exchange Technology Among Control Center Systems

The background and existing problems about data exchanging among multi-systems in the control center are introduced. The best way of data exchanging among systems are setting up a common information data platform system (CIDPS) CIDPS, which is located in the II and III sections, ensures the data to be shared by the multi-subsystems in the control center. Two methods of realizing CIDPS are DATA-PROXY and DATA-ENTITY. After discussing, the conclusion is come to that the DATA-ENTITY CIDPS method is preferred for the dispatching automation systems. Standard IEC 61970 is the theoretical base of CIDPS and it is the interactive technology standard among CIDPS and other system. A distributed object technology is the technology guarantee of CIDPS. The power model of CIDPS is built according to CIM Standard. CIDPS offers CIS interfaces for other systems accessing data. The sub-system can get the various power system models, parameters or real-time data by GDA or HSDA interfaces, and for a graphics centric method, SVG (scalable vector graphics) is a good candidate for the exchange format. Lastly, an application of CIDPS named OPEN3000 is presented particularly.
