Abstract: Simulation studies as well as field experiments were made to investigate the humanengineering aspects of control room, of the weak current type, of an electric power station.The topics under study were: (1) General layout of the control room in relation to perceptual-motor performanceof the human operators. (2) Comparison of work efficiency of operators in strong current and in weakcurrent control rooms. (3) Evaluation of the design of emergency signal system. (4) Comparison of two modes of signal presentation. (5) Coloration of the instrument panel and its bearing on the efficiency of vigi-lance tasks. This study was an appraisal of the man-machine system in the control room of anelectric power station; some general rules were also drawn thereof for improving controlroom designs.
