Abstract
A control system for a steam turbine includes an operator's panel and a programmed digital computer which generates valve position signals for the turbine throttle and governor valves. Mode select signals are generated at the panel and the computer includes a mode selector which provides for structuring the control system to implement external synchronizer, load runback, automatic turbine startup, operator automatic, manual and other mode selections.
