Energy management and control system for Iowa-Illinois gas and electric company

A new control center for energy generation, transmission and distribution (both gas and electric) at Iowa-Illinois Gas and Electric Company improves operator control of the systems and eliminates most manual record-keeping. The system uses two Xerox Sigma 5 computers, each with an effective memory of 96,000 words and back-up stored memory of 12 million bytes. Using analog and digital inputs supplied by Westinghouse REDAC remote processors, the system permits automatic response to many system changes, displays information to permit operator action, and effectively cuts response time even when operator intervention is necessary. On-line graphic and alphanumeric displays provide overviews of the total system or detailed studies of system segments, as necessary. All energy management accounting systems, including off-line analysis, record-keeping and reporting functions, are performed automatically.
