Decoulped Inlet This mode is typically used when the two controlled parameters during normal operation are turbine inlet pressure and extr/adm pressure (or flow). In this operating mode the turbine’s HP and LP valve actions are de-coupled to allow control of a turbine’s inlet pressure without interaction from extr/adm flow changes. With this mode of operation, turbine extr/adm pressure, is controlled by only moving the LP valve. Although turbine load is not controlled with this configuration, it is limited based on the turbine operating limits programmed. The turbine’s HP and LP valve actions are, however, still coupled to control turbine extr/adm pressure/flow without interaction from turbine inlet pressure or flow changes. Turbine inlet pressure is controlled by moving both the HP and LP valves simultaneously, thus no change in extr/adm pressure is created. For a change in either process the valves are repositioned to create a net effect of no pressure or flow change on the other process. With this mode of operation: ? Turbine inlet pressure can be controlled through either the 505E’s Auxiliary or Cascade PIDs. ? Extr/Adm pressure/flow can only be controlled through the 505E’s Extr/Adm PID. Decoupled Exhaust This mode is typically used when the two controlled parameters during normal operation are turbine extr/adm pressure (or flow) and exhaust pressure (or flow). In this operating mode the turbine’s HP and LP valve actions are de-coupled to allow control of a turbine’s exhaust pressure without interaction from extr/adm flow changes. With this mode of operation, turbine extr/adm pressure is controlled by only moving the HP valve. The turbine’s HP and LP valve actions are, however, still coupled to control turbine extr/adm pressure without interaction from turbine exhaust pressure or flow changes. Turbine exhaust pressure is controlled by moving both the HP and LP valves simultaneously, thus no change in extr/adm pressure is created. 

For a change in either process the valves are repositioned to create a net effect of no pressure or flow change on the other process. With this mode of operation: ? Turbine exhaust pressure can be controlled through either the 505E’s Auxiliary or Cascade PIDs. ? Extr/Adm pressure can only be controlled through the 505E’s Extr/Adm PID. Decoupled HP & LP This mode is typically used when the two controlled parameters during normal operation are turbine inlet pressure (or flow) and exhaust pressure (or flow).
