THERMODYNAMIC ANALYSIS OF A COMBINED CYCLE POWER PLANT OF 450 MW NETO POWER

U radu je analizirani kombinirani plinsko parni turbinski ciklus. Opseg rada uključuje termodinamičku analizu zadanog ciklusa matematičkim modelima, ispitivanje utjecaja promjene pojedinih parametara na stupanj djelovanja ciklusa. Također je bilo potrebno pronaći optimalne vrijednosti parametara ciklusa kako bi se postigla najveća iskoristivost kombiniranog ciklusa. Za analizu ciklusa koristio se računalni paket Engineering Equation Solver, EES. Na platformi EES – a napravljen je računalni kod, te je korišten za crtanje dijagrama i optimizaciju ciklusa.This paper analyzes the combined gas-to steam turbine cycle. The scope of work includes the thermodynamic analysis of the given cycle in mathematical models, and examination of the influence of changes in individual parameters on thermal efficiency of the cycle. It was also necessary to find optimum cycle parameter values to achieve maximum utilization of the combined cycle. The Engineering Equation Solver, EES, was used for the analysis of the cycle. A computer code was made on the EES platform and it was used to draw diagrams and optimize the cycle
