Distributed intelligence on distribution SCADA systems

Abstract

Today's electric power systems must serve a vastly different load than only a few years ago. With this change comes a new set of performance problems and opportunities for system reliability. Fortunately, significant advances in microprocessor based controls are occurring to prevent this from happening. This paper discusses these advances with respect to the distribution system as they relate to distribution automation control, monitoring, and protection. The effects of applying this equipment along the distribution feeders as well as in substations are discussed. This paper also shows arrangements that offer improved overall system reliability. Practical examples and application guidelines based on communication protocols are given.<>
