Abstract
U radu su analizirane metode za mjerenje fazora u uređajima numeričke relejne zaštite korištenjem Fourierovih filtara. Obrađene su značajke Fourierovih filtara s obzirom na duljinu impulsnog odziva. Metode za korekciju utjecaja eksponencijalno padajuće istosmjerne komponente odabrane su s obzirom na domenu korekcije (frekvencijska ili vremenska domena) i složenost njihove implementacije. Metode su analizirane optimizacijom odziva amplitude mjerenog fazora, s obzirom na parametre signala kvara. Definirana su mjerila kvalitete za ocjenu efikasnosti eliminacije utjecaja eksponencijalno padajuće istosmjerne komponente. Svaka od razmatranih metoda primijenjena je na stvarne signale kvarova.
Abstract (english)
This thesis presents analysis of phasor measurement methods in digital protective relays by using Fourier filters. Characteristics of Fourier filters have been investigated with respect to their impulse response length. Methods for suppression of exponentially decaying DC offset have been chosen with respect to type of correction domain (frequency or time domain) and numerical effort. Methods are analyzed by optimization of measured phasor amplitude response with respect to the fault signal parameters. Performance indices are defined in order to estimate suppression efficiency of exponentially decaying DC offset. Each investigated method is applied on real fault signals.
