Analysis of the modern electrified rail network

U ovom radu se opisuje električna vuča koja ima široku primjenu u industrijskim sustavima kao i sustavima željezničkog prometa. Opisivalo se njezine karakteristike počevši od povijesnog razvoja, sustava napajanja i elektromotornih pogona. Analizu i simulaciju su provedeni u programu zvanom DIgSILENT PowerFactory-u. U simulaciji je korišten model 14 Bus System testnog sistema. Provedeno je pet slučajeva u kojima su asinkroni motori bili uključeni ili isključeni na sabirnice koje su odabrane za promatranje. Za svaki slučaj u simulaciji, su snimljeni grafovi i postavljene tablice. Na grafovima se nalaze valni oblici struja, stupčasti grafikoni napona na sabirnicama ,te djelatna i jalova snaga na promatranim sabirnicama. Rad je priveden kraju uz adekvatan zaključak.This paper describes electric traction which has wide application in industrial systems as well as railway transport systems. Its characteristics were described, starting with its historical development, power supply system and electric motor drives. Analysis and simulation were performed in a program called DIgSILENT PowerFactory. The model 14 Bus System test system was used in the simulation. Five cases were conducted in which asynchronous motors were switched on or off on the busbars selected for observation. For each case in the simulation, graphs were recorded and tables were set. The graphs show the waveforms of currents, bar graphs of voltages on the buses, and the active and reactive power on the observed buses. The work was completed with an adequate conclusion
