Abstract

U ovom radu obrađene su teoretske osnove proračuna tokova snaga elektroenergetske mreže i obrađeni su određeni primjeri proračuna tokova snaga.
Opisani su matematički modeli proračuna tokova snaga na primjeru Gauss-Seidelove i Newton-Raphsonove metode kao i neke varijacije tih metoda.
U praktičnom dijelu zadatka koji je rađen u programskom alatu „NEPLAN“ provođene su i opisane simulacije tokova snaga različitih pogonskih stanja simulirajući sezonske promjene potrošnje.
Simulirani su i opisani primjeri različitih prijenosa električne energije između mreža, kao i primjer pojave Ferrantijevog efekta i primjer značajnog odstupanja napona u čvorištima.
Svi primjeri simulacije rađeni su na IEEE testnoj mreži od 24 čvorišta.

Abstract (english)

In this project theoretical basis of calculations of power flow and certain examples of the power flow are described.
Mathematical models of power flow calculation on the example of Gauss-Seidel and Newton-Raphson method and some variations of these methods are described.
In the practical part of the project that was done in the programming tool "NEPLAN", the power flows of different operating conditions, simulating seasonal changes in consumption, have been simulated and described.
There are simulated and described examples of various energy transmissions between networks, as well as an example of the appearance of Ferranti effect and example of significant deviations of voltage.
All examples of simulations are performed on the IEEE Reliability Test System of 24 nodes.
