ABSTRACT:
A steam generator in an electric power generating system is controlled by controlling turbine steam flow with control signals generated by a programmed digital computer system during startup, synchronization and load operation. The digital computer control signals are generated as a function of monitored turbine system conditions and parameters, the digital computer having means for interrupting the normal computing of the control signals when predetermined operating conditions are monitored. Turbine system parameter signals are periodically scanned and operated on so as to condition them for use in generating the control signals.
