Simulation of the Steam Injection of Gas Turbine

Dynamic model of the steam injected gas turbine was established in the modular modeling idea,the rotational inertia,cubage inertia and thermal inertia was considered,these models can be used commonly.The operating status of the systerm was simulated using the MATLAB software.The results indicte that the efficiency of the STIG cycle was heightened and the outlet temperature of the gas was reduced compared with the simple cycle.It's helpful for adding life of turbine and controling radiation of infrared ray.
