The thermodynamic analyses of the triple-pressure reheat combined cycle gas  turbines with duct burner are presented and discussed in this paper. The  overall performance of a combined cycle gas turbine power plant is influenced  by the ambient temperature, compression ratio and turbine inlet temperature.  These parameters affect the overall thermal efficiency, power output and the  heat-rate. In this study a thermodynamic model was development on an existing  actual combined cycle gas turbine (CCGT) (In this case study, an effort has  been made to enhance the performance of the CCGT through a parametric study  using a thermodynamic analysis. The effect of ambient temperature and  operation parameter, including compression ratio and turbine inlet  temperature, on the overall performance of CCGT are investigated. The code of  the performance model for CCGT power plant was developed utilizing the  THERMOFLEX software. The simulating results show that the total power output  and overall efficiency of a CCGT decrease with increase the ambient  temperature because increase the consumption power in the air compressor of a  GT. The totals power of a CCGT decreases with increase the compression rate,  while the overall efficiency of a CCGT increases with increase the  compression ratio to 21, after that the overall efficiency will go down. Far  there more the turbine inlet temperature increases the both total power and  overall efficiency increase, so the turbine inlet temperature has a strong  effect on the overall performance of CCGT power plant. Also the simulation  model give a good result compared with MARAFIQ CCGT power plant. With these  variables, the turbine inlet temperature causes the greatest overall  performance variation
