Zusammenfassung:	PURPOSE: A system and method for determining gas turbine firing and combustion reference temperatures having correction for water content in combustion air are provided to be operated by a wet compression system and to improve the control and sequencing of a gas turbine which is operated in different condition from an actual design level of water content. CONSTITUTION: A system and method for determining gas turbine firing and combustion reference temperatures having correction for water content in combustion air are composed of a system adjusting a gas turbine(10) combustion temperature control algorithm and combustion reference temperature algorithms based on exhaust gas temperature, turbine pressure ratio and compressor discharge temperature for water content in the air entering a compressor(12) differing from the design water content of ambient air. The water content in the ambient air is calculated by a control system(30) from measured data from a dry bulb temperature sensor(40) and a wet bulb temperature or humidity sensor(42). 주변 공기의 설계 물함량과는 다른 압축기(12)로 들어가는 공기내의 물함량에 대하여 배기 가스 온도, 터빈 압력비 및 압축기 방출 온도에 근거한 가스 터빈(10) 점화 온도 제어 알고리즘 및 연소 기준 온도 알고리즘을 조정하는 시스템이 개시된다. 주변 공기내의 물함량은 건식 벌브 온도 센서(40)와 습식 벌브 온도 또는 습도 센서(42)로부터의 측정 데이터로부터 제어 시스템에 의해 계산된다.
