Abstract
A programmed digital computer control system determines the turbine steam flow changes required to satisfy the speed and load demand made on the operation of a large electric power stream turbine for which substantially constant throttle pressure steam is generated. Load control is directed to plant electric power generation and it is based on feedforward valve positioning operation with feedback multiplication calibration for plant load and/or turbine speed error. Changes in the turbine operating level are limited by dynamic constraints applied by the computer.
