Combined cycle power plants are crucial for the production of electric power. They are becoming increasingly necessary for electric power generation. This study modeled the Sulaymaniyah Combined Cycle Power Plant 1500 MW in Chamchamal for three combinations of C6+ (C6, C7, C8) by energy and material balance in Excel and then simulated by Aspen HYSYS. Additionally, the effects of the mass flow rates of natural gas and air on gas turbine power, as well as the mass flow rate of water on steam turbine power, were investigated. The calculation results in Excel for the combination (47% C6, 36 % C7, 17 % C8) showed a strong correlation with real data collected from the power plant. According to optimum results, the combined-cycle efficiency is 58.91%. The optimum gas turbine power was achieved at a natural gas flow rate of 7.65 kg/s and an air flow rate of 423 kg/s. The optimum steam turbine power is obtained for more than 28 kg/s of water.
