ABSTRACT:
A control system for a marine turbine power plant is disclosed wherein the input signal to an electrohydraulic valve positioning circuit for ahead and astern turbines may be directly related to a desired valve position signal input set at a throttle lever. Hence, primary control is by a desired valve position signal. A speed feedback circuit is included and selectively applied to the desired valve position signal as a valve position trimming signal. Another input into the primary control or desired valve position is a malfunction proportional control signal which tracks boiler operation, shaft vibration and overspeed. The valve position signal is applied to the valve positioning circuit through a rate limiter which may be set at a fast, normal, or slow rate depending upon an input from a system interface board.
