In view of the process control of intercooled gas turbine

wet air condensation was put forward. Based on isopiestic and isothermal thermodynamics state change of wet air

wet air state change characteristic of intercooled gas turbine in the compressing and intercooling process was analyzed. The change relationship of state parameters of wet air which was compressed by low pressure compressor and cooled by intercooler was deduced. The conclusion was drawn that wet air can condense only in the intercooling process. The conditional discriminant of wet air condensation was found. Based on the feasibility of acquiring online measuring parameters

multi-parameter logic control method was founded by taking the static temperature after intercooling as the control target. Precision analysis of transformed control static temperature was carried out by combining with a project case. The results indicate the error is within 0.6‰. The control program applicable in project of intercooled gas turbine was developed

and the running control scheme under full conditions was presented.
