Advanced SCADA concepts

摘要

The typical utility system planner faces a wide variety of concepts and applications to consider when procuring a supervisory control and data acquisition (SCADA) system. The system's performance requirements are influenced by an arena of rapidly advancing technologies and a highly competitive business environment. Unlike other elements of the electric utility industry, these changes are not evolving specifically for the SCADA industry; they are being driven by other technology forums, with a profound impact on the SCADA system of the future. This article explores some of these concepts and suggests technology and business issues to consider when planning for the SCADA system of tomorrow. In particular the authors discuss the application of SCADA technology to a fully integrated substation system. They discuss substation controllers, substation design and operation, the substation protection interface, and the substation information system.
