In a steam turbine control system, the mechanical/hydraulic input to a mechanical control link within a servo enclosure controlling the steam supply valves to the turbine is replaced by an electrical/hydraulic control system while retaining all mechanical/hydraulic connections between the servo enclosure and the steam valves. A hydraulic cylinder is coupled to a control link in the servo enclosure which operates the steam valves. The cylinder is actuated by a servo control valve for modulating the flow of steam to the turbine. A fast trip valve forms par...
In a steam turbine control system having mechanical or hydraulic input to a mechanical control link within a control valve servo enclosure and which controls the output of said enclosure to an actuator of a steam valve for supplying steam to a turbine, a method of converting from a control system having the mechanical or hydraulic input to a control system having electrical/hydraulic input, comprising the steps of: disconnecting the mechanical or hydraulic input to said mechanical control link; coupling a hydraulic actuator to said link; coupling an elec...
