    Abstract: A trip control system for use with, for example, turbines, includes a porting manifold that supports and provides fluid to two or more trip manifolds, each of which includes a bleed circuit having two or more bleed valves connected in parallel between a trip header line and a return or dump line to bleed the hydraulic fluid pressure from the trip header line to thereby cause a trip. The bleed valves of each of the tripping manifolds are actuated by one or more control valves under control of a controller. The trip control system is doubly redundant in that the trip control system includes redundant trip manifolds operating in parallel so that each of the trip manifolds is able to be used to independently engage a trip of the turbine and each of the trip manifolds includes redundant sets of valves and other trip components that enable the trip manifold to operate to engage a trip of the turbine in the presence of a failure of one of the sets of components on a trip manifold, or while various components of the trip manifold are being tested.
