Abstract :
A combined cycle power plant consists of gas turbines, heat recovery steam generators, steam turbines and power generators. The power output of a gas turbine depends on the ambient temperature. Temperature control is important for preventing excessive temperature in the turbine. A single-shaft combined cycle unit is used in this study to investigate the effect of temperature control in its output control response when operates near its rated capacity. Gas turbine thermodynamic relations obtained from practical combined cycle unit operations are used to develop a flow diagram to simulate the steady state gas turbine parameters variations and unit load change curves can be obtained. Simulation results obtained in this study are helpful for understanding the temperature effects on the combined cycle unit outputs
