ADMISSION or EXTR/ADM Control The procedure for enabling the Extr/Adm PID with Admission or Extraction/Admission applications is the same. In all cases it is assumed that an external trip valve or a trip-and- throttle valve is used to completely stop any admission steam from entering the turbine upon a system shutdown condition. Admission (Adm) or extraction/admission (Extr/Adm) control can be enabled and performed after one of the three starts has been performed. After a start-up, the HP and LP valve limiters should normally both be fully open. If either limiter is not fully opened, it will interfere with automatic governor operation. To perform a bumpless transfer into Adm or Extr/Adm control the pressures on each side of the Adm trip valve or T&T valve should be matched. The following procedure allows a bumpless transfer into Admission or Extraction/Admission control to be performed.
Adm or Extr/Adm Enabling procedure: 1. Verify that all “Extr/Adm enable permissives” are met (listed above). 2. Match the Extr/Adm setpoint to that of the pressure on the plant side of the Extr/Adm T&T valve. (Skip this step if Setpoint Tracking is used.) 3. Vary the Extr/Adm Demand setpoint to match the turbine’s internal Extr/Adm pressure to that of the pressure on the plant side of the Ext/Adm T&T valve. 4. Open the Extr/Adm Trip-and-Throttle valve. 5. Enable Adm or Extr/Adm control. All the functions required to bumplessly enable and disable Adm or Extr/Adm control can be performed through the 505E keypad, contact inputs, or Modbus. To perform the above procedure from the 505E’s keypad, press the Ext/Adm key to view the Extr/Adm control screen (adjust setpoint), press the Scroll Down key to display the “Extr/Adm Demand” screen (adjust to match pressures), then press the Scroll Up key to display the Extr/Adm Status screen (press the “Yes” key to enable the function). The 505E only accepts an enable command if all related permissives are met (see enable permissive list above). An enable/disable command may be given from the 505E keypad, a contact input, or through Modbus. The last command given from any of these three sources dictates the state of the Extraction control.
When a contact input is programmed to function as an enable/disable command a closed state represents an enable command and an open state represents a disable command. This contact can either be open or closed when a 505E trip condition is cleared. If the contact is open it must be closed to issue an enable command. If the contact is closed, it must be opened and re-closed to issue an enable command. The following procedure allows Adm or Extr/Adm control to be disabled in a controlled manner: Adm or Extr/Adm Disabling procedure: 1. Disable Adm or Extr/Adm control. (At this point the Extr/Adm Demand setpoint will step to the Extr/Adm PID’s last position, take control of the process from the PID, then ramp back to the setting that was used to enable Extr/Adm control. This setting should be at or close to the zero flow level.) 2. If necessary manually adjust the Demand setpoint to reach zero Extr/Adm flow. 3. Close the Extr/Adm Trip-and-Throttle valve.
