Preliminary case studies on common information exchanges for power system management

This paper discusses the applicability of common information exchanges based on IEC standards as well as conventional and state-of-the-art methodologies for power system management, and clarifies necessary improvements for the information exchange process as case studies. A SCADA and telecontrol system require an integrated information model with device, system configuration and information exchange model components. A special protection system can easily determine power system stability or system separation by utilizing an abridged substation model as topology information. Remote operation and maintenance of protective relays can be also simplified by employing standardized information exchanges.
