Optimization of gas turbine cycle

U ovom radu je analiziran plinsko-turbinski dio kombiniranog postrojenja. Kao referentni model, korišten je predložak rada asistenta na Katedri za energetska postrojenja i energetiku dr.sc.Mislava Čehila. U programskom paketu MATLAB napravljen je matematički model danog plinsko-turbinskog postrojenja koji obuhvaća modele kompresora, komore izgaranja i turbine. Algoritam rješavanja modela osigurava zadovoljavanje masenih i energetskih bilanci za zadano vanjsko opterećenje i temperaturu. Rezultati su uspoređeni s referentnim modelom te su prepoznati i objašnjeni uzroci promjene termodinamičke efikasnosti plinsko-turbinskog dijela postrojenja.This paper analyzes the gas turbine combined plant part. As a reference model, used the template work assistant at the Department of Energy and Energy dr.sc.Mislava Čehila. The software package MATLAB created a mathematical model of a given gas-turbine plant which includes models of compressors, combustors and turbines. The algorithm solving model provides satisfying mass and energy balances for a given external load and temperature. The results are compared with the reference model and are recognized and explained the causes of the changes the thermodynamic efficiency of a gas turbine part of the plant
