Abstract
Abstract In a supervisory control computer system of a compound generating plant, an output permission selecting switch for a man-machine interface means such as CRT, T/W or the like is installed corresponding to gas turbine generating facilities and steam turbine generating facilities, and condition of the output permission selecting switch is added to output requirements to the man-machine interface means, thereby selection of output/stop is performed per each of the generating facilities.
