Abstract

U ovom su radu istražene mogućnosti automatiziranja elektromagnetskog proračuna parametara sinkronog generatora s istaknutim polovima (sinkronog hidrogeneratora) primjenom metode konačnih elemenata.
U okviru rada izrađena je aplikacija za automatiziranje proračuna korištenjem gotovog programskog paketa MagNet Infolytica. Automatizirana je izrada modela sinkronog hidrogeneratora, određivanje magnetske slike stroja za prazni hod, određivanje krivulja praznog hoda i uzbudne struje praznog hoda, određivanje sinkronih reaktancija, te određivanje karakteristike opterećenja, uzbudne struje za nazivnu radnu točku kao i prikaz magnetske slike stroja za istu.
Opisani su postupci automatizacije, te je proveden proračun na primjeru izvedenog sinkronog hidrogeneratora s razlomljenim brojem utora po polu i fazi.

Abstract (english)

Possibilities to automate electromagnetic analysis of the salient pole synchronous generator by the finite element method has been explored.
An application has been created for automation of the analysis by Infolytica’s MagNet software. It automates the salient pole synchronous generator model building within MagNet, as well as magnetostatic analysis of the generator at no load, induced voltage characteristic at no load and field current for rated voltage at no load, determination of saturated direct and quadrature axis synchronous reactances. The field current at rated load and load charcteristic has also been automated.
The procedures for automation have been described and the application‘s operation has been tested in case of the existing synchronous generator.
