Integration of an operations information system into an energy management and control system

The Houston Lighting and Power Company Energy Management and Control System (EMACS) represents a departure from designs historically associated with energy management systems. The EMACS inherently provides a data collection system that is useful to a variety of other users not associated with system dispatching. To meet the needs of those users, the EMACS includes an operations information system (OIS) that can support programs and displays identical to those provided to power system dispatchers. The OIS, however, is intended to be used by personnel in distribution-zone offices, power plant control rooms, and a variety of other departments. The reasons for inclusion of the OIS as well as alternate implementation is discussed
