Abstract

1486199 Automatic control of steam turbine plant WESTINGHOUSE ELECTRIC CORP 4 Nov 1974 [6 Nov 1973 #] 47571/74 Heading G3N [Also in Division G4] A control system for a steam turbine power plant includes two digital computers one of which acts as a standby unit and has its input and output settings updated so that in the event of a malfunction of the operating computer a 'lumpless' changeover of control to the standby computer is obtained.
