Beschreibung
Zusammenfassung:	A water-injection control system is disclosed for a water supersaturation system installed in a gas turbine air intake system for augmenting gas turbine power output during operation at high ambient-air temperature, while maintaining the water content in the intake air within limits acceptable to the gas turbine as indicated by measured gas turbine operating parameters. The control system starts, stops, modulates, and limits water supplied to the supersaturating system based on the humidity or dew-point temperature of the ambient air, dry-bulb temperature of the ambient air, compressor inlet air flow, and gas turbine parameters indicating operation at or near maximum output.
