Abstract

V industrijskih omrežjih vedno bolj narašča število naprav, ki predstavljajo vir harmonskega popačenja napajalne napetosti. Pri umeščanju takšnih naprav v zaključena industrijska omrežja je treba upoštevati vpliv naprav na ostalo omrežje, kot ga predpisuje standard SIST EN 61000-2-4[1]. V diplomskem delu sta opisana osnovni namen in izvedba harmonske analize v izbranem zaključenem industrijskem omrežju. Poleg osnovne naloge kompenziranja jalove moči je v nalogi prikazan vpliv dvojnega kompenzacijskega filtra na napajalno napetost v izbrani priključni točki. Podan je predlog za učinkovito kompenzacijo jalove moči osnovne harmonske komponente in kompenzacijo tokov harmonskih komponent višjega reda. V zaključku so podane ugotovitve različnih vplivov na napajalno napetost v izbrani priključni točki, ob izbrani filtrski kompenzacijski napravi.

Secondary title:	ANALYSIS OF VOLTAGE HARMONIC DISTORTION IN AN INDUSTRIAL ELECTRICITY NETWORK
Secondary abstract:	In industrial networks the number of devices that represent a source of harmonic voltage distortion is increasing. In the placement of such devices in closed industrial networks it is necessary to consider the impact of these devices on the rest of the network devices as prescribed by the standard SIST EN 61000-2-4 [1]. This thesis describes the basic purpose and implementation of harmonic analysis of the selected closed industrial network. In addition to the basic functions to compensate reactive power, this diploma thesis shows the influence of dual compensation filter on the supply voltage at the selected connection point. The thesis proposes and efficient fundamental harmonic component reactive power compensation, as well as compensation of higher order harmonic currents. In the conclusion, the findings related to the impacts caused by the chosen filter compensation devise on supply voltage at the given connection point are discussed.
