OpFlex Sliding Fuel Pressure Control features*

• Closed loop control using pressure and valve position feedback with logic to adjust the inter-stage pressure setpoint and balance what actually matters… valve operating limits to maintain stable and accurate fuel flow control.
• Advantages… allows continued operation with lower gas fuel supply pressure by accounting for all GT operating variation
  • ambient variation
  • fuel variation
  • future gas turbine hardware/control upgrades
  • actual fuel splits
  • combustor mode
• Refined protections to minimize impact to operations.
• Improved flexibility on automatic transfers to liquid fuel
