Abstract

U radu je napravljena usporedba dva pristupa modeliranju dinamike jednostavnog sustava koji uključuje spremnik topline sa spiralnim izmjenjivačem. Razvijeni dinamički modeli validirani su na temelju eksperimentalnih podataka. Eksperiment je proveden u Laboratoriju za energetska postrojenja. U prvom dijelu rada opisan je predmetni sustav i njegove osnovne komponente. Opisana je oprema za upravljanje i praćenje procesa te princip procesne regulacije u sustavu. U drugom dijelu rada razvijena su dva detaljna matematička modela sustava. Razvijeni modeli potom su validirani. U završnom dijelu rada međusobno su uspoređeni rezultati simulacija temeljenih na modelima s koncentriranim i distribuiranim parametrima. Simulacije su izvedene u programskom paketu MATLAB, odnosno dodatku programa SIMULINK.

Abstract (english)

The paper compares two approaches to modeling the dynamics of a simple system that includes a heat storage tank with a spiral exchanger. The developed dynamic models were validated on the basis of experimental data. The experiment was conducted in the Laboratory for energy plants. The first part of the paper describes the subject system and its basic components. The equipment for managing and monitoring the process and the principle of process regulation in the system are described. In the second part of the work, two detailed mathematical models of the system were developed. The developed models were then validated. In the final parto f the paper, the results of simulations based on models with concentrated and distributed parameters were compared. The simulations were performed in the MATLAB software package, i.e. the SIMULINK program add-on.
