SIMULATION OF THE REAL SHORT-CIRCUIT IN THE DISTRIBUTION NETWORK WITH MATLAB
KOMUNALNA ENERGETIKA / POWER ENGINERING, 27
The article deals with the simulation of the real short-circuit in the distribution network with Matlab. The purpose is to show how in simulation of the real short-circuit in software package Matlab determine model parameters. Assuming that we know all the parameters of network elements can in principle produce a model of the distribution network that is completely identical to the actual network. Nevertheless, we have in any real short circuit variables that need to be taken into account in the simulation. In conclusion, is by comparing the timings of effective short-circuit currents in single-phase, two-phase and three-phase short circuit, illustrate the correlation of simulation results and actual measurement.

IMPACT OF THE GENERATOR TO SHORT-CIRCUIT CONDITIONS IN THE DISTRIBUTION NETWORK
KOMUNALNA ENERGETIKA / POWER ENGINERING, 27
The article deals with the analysis of the impact of the generator to short-circuit conditions in the distribution network. The aim is to determine the effect of synchronous generator on short-circuit currents, which are at the point of connection baseline data for the design and sizing of individual network elements. Short-circuit currents will be in point of short circuit determined using a DMS software tool that is developed for the analysis of the actual situation in the network and also enables the calculation of the parameters of all types of short circuits. Analysis of the impact of the generator to the short-circuit currents in the distribution network is carried out in point near the generator and point away from the generator by comparing the results with the generator on and off.
