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.

Claims

1. A supervisory control computer system of a compound generating plant, comprising:

(a) a data input/output device for inputting data of gas turbine generating facilities and steam turbine generating facilities of the compound generating plant;

(b) an operation unit for receiving an output from the data input/output device;

(c) a memory connected to the operation unit for storing data of the gas turbine facilities and the steam turbine facilities;

(d) a plurality of display devices for indicting a message, a system diagram or the like based on output from the operation unit;

(e) an operator console for performing the display mode of the display devices through the operation unit; and

(f) indication permission selecting switches of the display devices installed corresponding to each of the generating facilities and connected to the operation unit for preventing a change in the display devices concerning the respective generating facilities.

2. A supervisory control computer system of a compound generating plant constituted by a plurality of gas turbines and steam turbines, comprising:

(a) a data input/output device for inputting data of gas turbine generaitng facilities and steam turbine gnerating facilities of the compound generating plant;

(b) an operation unit for receiving output from the data input/output device;

(c) a memory connected to the operation unit for storing data of the gas turbine facilities and the steam turbine facilities;

(d) a standing display device for indicating a message, a diagram or the like based on an output from the operation unit concerning an operating turbine generating facility;

(e) a non-standing display device for displaying information based on output from the operation unit concerning a non-operating turbine generating facility; and

(f) a plurality of switches corresponding to the generating facilities for selecting either the standing display device or the non-standing display device for displaying information of the generating facilities on the respective display devices in accordance with operating or non-operating status of the generating facilities.
