Title: Energy management system survey of architectures

Abstract

Since the earliest days of computers, one trend has been continuous: the only thing that has grown faster than computer power is the demand for computer power. The challenge for system designers is to accommodate this type of growth in a manner that avoids replacing the whole system often. Three very different approaches are being used by the major suppliers today, but with a common them; functions are distributed to various computers and various types of computers to meet the diverse requirements of an EMS. Early control centers were built around a single computer or a redundant pair of computers. Most of the systems delivered before 1975 were based on the Xerox Sigma 5 and Sigma 9 computers, the premier real-time processors of their day. Xerox left the computer business, and suppliers adopted various minicomputers as the heart of their systems. The popular choices were the SEL (later Gould) 32 series, the Harris H series, the Modular Computer Systems MODCOMP IV and CLASSIC series, and the CDC 16-bit machines like the CYBER 18. Like the Sigma 5, these machines are all excellent real-time processors and could easily handle the requirements of early control centers.
