Abstract

U radu je simuliran elektromotorni pogon manjeg putničkog električnog broda. Pogon se sastoji od izvora napajanja (baterije), frekvencijskog pretvarača i asinkronog motora. Ključne dimenzije motora određene su analitički, nakon čega je motor modeliran u programskom paketu MagNet. Provedene su dvije vrste simulacija, Transient 2D with Motion i Time-Harmonic simulacija. Programski paket MagNet zatim je povezan s programskim paketom MATLAB. Korištenjem skripti pojednostavljen je i automatiziran postupak izvođenja simulacija što je iskorišteno za izradu mapa motora. Nakon toga, u programu MATLAB izvršen je proračun kretanja broda. Na temelju podataka iz mapa motora, funkcijom fmincon minimiziran je iznos struje potreban da bi motor razvio traženi moment. Parametri gibanja broda i radna karakteristika motora prezentirani su tablično i grafički.

Abstract (english)

In this thesis, an electric drive of a small passenger ship is simulated. The drive consists of a source of power (battery), a frequency converter and an induction motor. After all the key parameters had been calculated, the motor was modeled in MagNet simulation software. Two types of simulations were performed, Transient 2D with Motion and Time-Harmonic simulation. Afterward, MagNet software was integrated with MATLAB programming language. The running of simulations was simplified and automated by using scripts. The results of simulations were retrieved and then used to make electric motor maps. Calculations of ship movement were performed in MATLAB. Based on data from motor maps and by using the fmincon function, stator current necessary to produce the required torque was minimized. Ship movement parameters and motor performance are presented in tables and graphically.
