description: Â The topic of the final qualifying work: Â«Combined plant with a capacity of 500 MW: selection and justification of parametersÂ».Â The paper investigates the parameters of a combined-cycle gas plant based on a gas turbine plant with a gas temperature after the combustion chamber t3Â = 1400 Â° C.Â The study was carried out by the calculation method and consisted in the sequential calculation of the main units that make up the combined cycle gas plant. Calculations were carried out on the basis of the basic equations of processes and thermal balances of individual elements.Â The relevance of the work lies in the prospects for the use in the domestic power industry of stations with combined-cycle power units based on gas turbine installations with gas temperatures at the gas turbine inlet of about 1400-1600 Â°C, which correspond to those used in the world energy industry.Â As a result of the work performed, optimal parameter values were obtained for a combined-cycle gas plant with a three-pressure utilization circuit and intermediate overheating. The efficiency of the potential installation was 59.9%, the capacity was 482 MW (under ISO ambient conditions and a pressure in the condenser of 9 kPa).Â The results of the work can be used as a theoretical basis for the development of a domestic gas turbine installation and the design of a combined-cycle power unit based on it.
