Investigation of Water and Steam as the Working Fluids in a Fluid Amplifier Speed Governor for Turbine Generator Sets
[Technical Report, Final Report]

Pagination or Media Count:
The dynamic requirements of a steam-operated actuator for the steam valve can be satisfied with fluid amplifier circuits by the use of high gain feedback circuits. The efficiency compares favorably with electromechanical hydraulic systems. Present state-of-the art in fluid circuit technology limits the minimum actuator area to approximately 20 sq. in. for a 70 radsec. closed-loop bandwidth on the actuator stage. The practical problems associated with the actuator are the primary obstacles to the mechanization of the actuator stage.
