Abstract
Tema ovog rada je simulacija regulacije protoka napojne vode u suvremenim termoenergetskim postrojenjima. U radu je izveden matematički model dinamike napojnog čvora koji se sastoji od dvije napojne pumpe, napojnog ventila i pripadnog mimovodnog ventila s pripadajućim dionicama cjevovoda. Simulacija sustava napajanja s odgovarajućim regulacijskim podsustavom protoka napojne vode simuliran ju u programskom paketu MATLAB, odnosno dodatku programa SIMULINK. Za potrebe rada razrađen je pojednostavljeni matematički model preko kojeg su izražene promjene masenog protoka, tlaka, entalpije i brzine vrtnje pumpe. Rezultatima simulacije prikazuje se promjena masenog protoka, brzina vrtnje pumpe i prirast tlaka ovisno o varijaciji ulaznih veličina i koeficijenata, odnosno otvorenosti ventila, koeficijenta protoka i ložišta te referentnog protoka.
Abstract (english)
The subject of this paper is simulation of the feed water flow control in modern thermal power plants. Feed water node consist of two feed water pumps, feed water valve, bypass valve and corresponding piping sections. The mathematical model of the feed water flow control was simulated in the MATLAB software package and addition SIMULINK program. For the purpose of this paper, a simplified mathematical model was developed based on mass flow, pressure, enthalpy and pump speed. The simulation results show the change in mass flow rate, pump speed and pressure gain depending on the variation of input sizes and coefficients, i.e., valve openings, flow coefficient and fuel flow and reference flow.
