Method and system for incorporating an emission sensor into a gas turbine controller

A method for determining an estimated operating emission level (72) for an exhaust of a gas turbine (19) comprising the steps of: periodically determining an estimated emission level (72) from an output of emissions transfer algorithm (74) wherein said algorithm includes a trim factor (K); determini...

Beschreibung
Zusammenfassung:	A method for determining an estimated operating emission level (72) for an exhaust of a gas turbine (19) comprising the steps of: periodically determining an estimated emission level (72) from an output of emissions transfer algorithm (74) wherein said algorithm includes a trim factor (K); determining a current trim factor (K) based on a ratio of a current output (76) of a healthy (82) emission sensor (78) monitoring the exhaust and of the estimated emission level from a prior determination (Z), and applying a prior trim factor (84) previously applied to determine the estimated operating condition of the emission sensor is unhealthy.
