Independent GT load and exhaust temperature control to customize startup and operational load paths, enabling lower fuel burn and faster combined cycle starts (requires AutoTune MX).
Shortened start-up time to full speed-full load to reduce fuel cost, reduce emissions and capture additional revenue. Enables 10-15 minute simple cycle start times.
Combined control software and valve hardware system to enable purge to be conducted during prior shutdown, followed by isolation of the fuel manifold with a valve system, such that purge can be skipped on start-up, enabling 15+ min. combined cycle start time savings (NFPA-85 compliant).
Simplified start permissives, automated system pre-start checks (various pumps, fans, valves), and HMI start-up sequence screens to reduce the number of failed starts.
Reduce your gas fuel supply pressure (P2) requirements during start-up and operation to better accommodate low or fluctuating pressure, and possibly enable reduced gas compressor usage. Additionally, Sliding Fuel Pressure Control can reduce likelihood of trips or runbacks.
Automated start-up control, revised permissives, and rotor stress management using Model-Based Control to enable fast, repeatable steam turbine start times.
Model-based control of attemperation flow to better regulate steam temperature during start-up and transients, enabling more stable operation, fewer trips, and improved efficiency.
Automation of the HRSG blending process to better manage steam temperature and flow when bringing additional gas turbines online in combined cycle plants. This enables more stable operation, fewer trips, and more energy production for the lead gas turbine.
Improved setpoint management and tuning of HRSG drum level control to enable more stable operation during starts and transients, and fewer trips.
Model-based control of Selective Catalytic Reduction (SCR) system ammonia flow to enable enhanced operation during start-up and transients, resulting in less ammonia slip and lower overall NOx emissions.
Automated fast cooldown process using temperature matching logic in reverse, to safely reduce ST cooldown times by 50% or more, enabling critical path maintenance activities to begin 24 to 36 hours sooner.
Advanced combustion control to enable low visible emissions above full speed no load and reduced cumulative start-up NOx emissions.
