Human-factors review of electric-power-dispatch control centers. Volume 1. Survey results summary. Interim report

Human factors is a systems-oriented interdisciplinary specialty concerned with influencing the design of systems, equipment, facilities, and operational environments to promote effective system operations through emphasis on efficient and reliable operator performance. Phase I of this project evaluated a sample of 13 contemporary electric power control centers by conducting site surveys; these surveys included checklists, guided interviews, photography, direct physical measurement, and technical discussions with operators, management, and supervisory personnel at each site. The project evaluated the information available to the operator and the physical interface between the operator and power systems, as well as the operational setting in which tasks are performed. Guidelines for the application of human factors principles are given where applicable. Particular attention was given to the design of the cathode-ray tube (CRT) interface, the data base, facility lighting, training, manning, and work stress. Several potential areas for further study are identified. Volume 1 is a summary report of the findings of the dispatch control center human factors survey.
