Abstract
Rad se zasniva na proračunu faktora snage i snaga u zadanom sustavu. Na osnovi zadanih podataka, dobivenih simulaciom u ATP-u raspisao se svaki valni oblik napona i struje radi crtanja grafova u Microsoft Exscelu. Iz grafova se vidi kako se razlikuje svaki harmonik jedan od drugoga te kako utječu na rezultantni valni oblik. Da bi se dobile ukupne snage računaju se snage svakog harmonika te u konačnici se zbroje i dobiju se prividna, jalova trenutna i snaga distorzije te se na kraju dobije faktor snage. Ovaj postupak se proveo na dva zadana slučaja. Iz dobivenih rezultata se vidi faktor snage ne iznosi jedan kao u idealnom slučaju nego iznosi nešto manje što znači da u krugu imamo reaktivnih elemenata koji utječu na kvalitetu električne energije.

Parallel abstract (English)
The work is based on a calculation of the power factor and power in a given system.Based on material data obtained by simulation in ATP, each wavefrom of voltage and current is numerically written for drawing graphs in Microsoft Excel .From the graph you can see difference between each harmonic and how they affect the resulting wavefrom. To obtain total power, we calcute power each harmonic and then add them up to get the apparent raective,current and power disortion and eventually gain power factor.This procedure is carried out on two default cases. The obtained results show that the power factor value is not one as in an ideal situtation, but is slightly less, which means that we have reactive elements in circuit that affect the quality of electricity.
