Higher thermal efficiency and operational flexibility are required for next generation thermal power plants to reduce CO2 emission and cope with the increase of power by renewable energy which is changeable depending on the weather. The Advanced Humid Air Gas Turbine (AHAT) system is expected to meet these requirements. The system concept and cycle performance of the AHAT system were verified by operational tests of a 3MW-class and a 40MW-class pilot plant so far. However, the operational flexibility of the system such as load change rate, start-up time, has not been clarified sufficiently by experiment and simulation. Therefore, we develop the dynamic simulation model of the system and analyze the start-up characteristics in this paper.
