## Abstract (Croatian)

U diplomskom radu napravljen je matematički model Bloka K u termoelektrani – toplani (TE - TO) Zagreb. Model obuhvaća proračun dvije plinske turbine jednakih karakteristika, proračun dva generatora pare na otpadnu toplinu s dva kruga pare jednakih karakteristika, proračun parne turbine te proračun izmjenjivača topline C4 i C6 za područno grijanje. Matematički model izrađen je u programskom jeziku Visual Basic for Application (VBA) za program Microsoft Excel. Razradom proračuna omogućeno je da sva rješenja budu fizikalno moguća te da rješenja budu u postavljenim uvjetovanim granicama. Prikazani su rezultati za tri odabrane temperature (-24°C, 15°C, 37°C) na opterećenjima od 60% do 100%.

## Abstract

This thesis presents a mathematical model of unit K in cogeneration plant TE – TO Zagreb. The mathematical model includes calculation of two gas turbines with the same characteristics, calculation of two heat recovery steam generators with two steam pressure levels, calculation of the steam turbine and the calculation of two heat exchangers C4 and C6 for district heating. A mathematical model was developed in Visual Basic for Application (VBA) for Microsoft Excel. Development of the model allowed for all solutions to be physically possible and that the solutions are within the set of boundary conditions. Results are shown at three environmental temperatures (-24°C, 15°C, 37°C) and for loads from 60% to 100%.
