Abstract
U ovom diplomskom radu opisan je matematički model za proračun preliminarne konstrukcije turbine s radijalnim ulazom radnog fluida (u daljnjem tekstu radijalna turbina) za rad u geotermalnoj elektrani. Elektrana je izvedena kao jednostavni Rankine-ov ciklus s organskim radnim fluidom (u daljnjem tekstu ORC). Definirani matematički model za preliminarnu konstrukciju radijalne turbine uključen je u matematički model geotermalnog ORC postrojenja u svrhu provođenja istovremene optimizacije parametara ORC-a i radijalne turbine. Funkcija cilja optimizacije je neto dobivena snaga postrojenja. Optimizacija je provedena za 6 kombinacija neovisnih varijabli optimizacije za slučaj da radijalna turbina nema difuzor i za slučaj da radijalna turbina ima difuzor. Proračun i optimiranje izvedeni su u programskom paketu EES (Engineering Equation Solver). Proračunom su definirane preliminarne vrijednosti geometrijskih veličina turbine. Analizom rezultata utvrđen je utjecaj pojedinih ulaznih varijabli na optimalnu radnu točku radijalne turbine i ORC-a, te na veličinu i učinkovitost turbine.
Abstract (english)
In this master’s thesis, a mathematical model for preliminary design of a radial-inflow turbine (RIT) in a geothermal power plant is defined. The power plant is designed as a simple Rankine cycle with an organic working fluid (Organic Rankine Cycle, ORC). The defined mathematical model for the preliminary design of the RIT is integrated in the mathematical model of the geothermal ORC plant for the purpose of conducting simultaneous optimization of the parameters of the ORC and the RIT. The optimization objective function is the nett generated power of the plant. The optimization was carried out for 6 combinations of independent optimization variables for a turbine with a diffuser and a turbine without a diffuser. Calculations and optimization were performed using EES (Engineering Equation Solver) software. Preliminary values of the turbine geometry were defined by the calculation. The analysis of the results determined the influence of individual input variables on the optimal operating point of the RIT and ORC, as well as the influence on the size and efficiency of the turbine.
