Beschreibung
Zusammenfassung:	Systems (10), program products, and methods for adjusting operating limit (OL) thresholds (144B, 144D) for compressors (12) of gas turbine systems (11) based on mass flow loss (130) are disclosed herein. The systems (10) may include at least one computing device (100) in communication with the gas turbine system (11), sensor(s) (106) measuring operational characteristic(s) of the gas turbine system (11), and a pressure sensor (104) measuring an ambient fluid (20) pressure surrounding the gas turbine system (11). The computing device(s) (100) may be configured to adjust operational parameters of the gas turbine system (11) by performing processes including determining a mass flow loss (130) between an estimated, first mass flow rate (124) and a calculated, second mass flow rate (128) for the compressor (12) of the gas turbine system (11), and adjusting an OL threshold (144, 144A, 144C) for the compressor (12) of the gas turbine system (11) based on the mass flow loss (130). The OL threshold (144, 144A, 144C) for the compressor (12) may be below a predetermined surge threshold (140) for the compressor (12).
