Trip manifold assembly for turbine systems

A system, comprising:

• a plurality of stop valves coupled to a turbine system;
• a hydraulic power unit (HPU) configured to deliver a flow of fluid to the plurality of stop valves to regulate the turbine system;
• and
• a trip manifold assembly (TMA) communicatively coupled to the plurality of stop valves and the HPU, comprising:
• a plurality of block valves configured to receive the flow of fluid from the HPU, wherein the plurality of block valves are disposed so as to provide for a plurality of parallel output flow streams exiting the plurality of block valves;
• a plurality of parallel solenoid valves configured to admit the flow of fluid to actuate the plurality of block valves, a plurality of dump valves, and a plurality of relay valves of the TMA, wherein the plurality of relay valves is respectively coupled to each of the plurality of solenoid valves, wherein the plurality of dump valves is respectively coupled to each of the plurality of solenoid valves and each of the plurality of relay valves, wherein the dump valves are actuated by the relay valves, and wherein the plurality of dump valves is configured to depressurize a trip header of the TMA as an output to operate the plurality of stop valves to interrupt an operation of the turbine system.

A system, comprising:

• a trip manifold assembly (TMA), comprising:
• a plurality of block valves configured to receive a flow of fluid from a hydraulic power unit (HPU), wherein the plurality of block valves are arranged so as to provide for at least one output flow stream exiting the plurality of block valves;
• and
• a plurality of solenoid valves configured to admit the flow of fluid to actuate the plurality of block valves;
• wherein the plurality of block valves are arranged so as to provide for at least two or more parallel output flow streams exiting the plurality of block valves;
• wherein the plurality of block valves are arranged in a plurality of groups of two block valves per group so that each group of the plurality of groups of block valves enables a redundant flow control over a different one of the plurality of parallel output flow streams exiting the respective group of block valves such that when the TMA depressurizes via the plurality of dump valves, all of the parallel output flow streams of the plurality of parallel output flow streams close even in the event that one of the two block valves in each group of block valves is not operational, wherein each solenoid valve of the plurality of solenoid valves is configured to actuate two block valves in different groups of the plurality of groups of block valves;
• wherein the TMA is configured to regulate the flow of fluid to control the operation of the plurality of stop valves as a mechanism to interrupt an operation of the turbine system.
