摘要：This paper presents the results of optimization of the design parameters of the combined cycle power plant, which was conducted using a genetic algorithm. Thermodynamic calculations were made for the objective function, which was the power of the steam turbine. The process of optimization was divided into three structures of combined cycle power plants: single-pressure (1P), double-pressure with steam reheater (2 PR) and triple-pressure with steam reheater (3PR). Each system was optimized in two versions: with and without steam extraction in the turbine in the steam cycle, for the integration of the systems with a CO2 separation and compression unit (CCS). The resulting values of power and efficiency of the optimized systems are summarized and compared with each other. A sensitivity analysis was performed for the 2PR and 3PR systems in the versions with steam extraction. The impact of energy consumption in the process of desorption in the CO2 separation unit on the decrease in efficiency of combined cycle power plants was also examined.
