This paper shows the thermodynamic performance of gas turbine systems with air humidification. We make sure that humidifying the air increases the power output and thermal efficiency although air humidification method does not influence to the thermal efficiency greatly under the same calculating conditions. Moreover, humidifying the air is more effective in regenerative cycle, such as AHAT, TOPHAT, REVAP, and HAT cycle. They all show high thermal efficiency near 50%HHV. This is because the exhaust heat can be recovered enough by humidifying and the compressor power is decreased by each method in these systems. Moreover, the result of parameter studies show that the best efficiency of each system is comparable and each system has optimum point of moisture amount to the thermal efficiency.
