Abstract

U radu je opisan utjecaj nelinearnih trošila na mrežu. Prikazan je pregled standarda i preporuka koji propisuju udio viših harmonika napona i struje u distributivnoj mreži. Opisana je podjela aktivnih filtara prema načinu spajanja, brzini odziva i kompenziranoj varijabli. Objašnjeni su principi rada shunt, serijskog i serijsko-paralelnog aktivnog filtra. Upravljanje shunt aktivnim filtrom je izvršeno pomoću diskretne Fourierove transformacije i impulsno širinske modulacije. Serijski filtar koristi upravljanje fazno zaključane petlje i impulsno širinsku modulaciju. Serijsko-paralelan aktivni filtar ujedinjuje upravljanja serijskog i shunt aktivnog filtra za istovremenu kompenzaciju harmonika napona i struje.

Abstract (english)

The paper describes the influence of nonlinear loads on power system. Standards and recommendations which limit the percentage of voltage and current harmonics in the power system are presented. The paper gives classification of active filters based on power-circuit connection, power, response speed and compensated variable is described. The principles of operation of the shunt, serial and serial-parallel active filter are explained. Control of the shunt active filter is performed using discrete Fourier transform and pulse width modulation. The serial filter uses phase locked loop control and pulse width modulation. The series-parallel active filter combines control algorithms of a serial and a shunt active filter for individual voltage and current harmonic compensation.
