Abstract
Rad je podijeljen u nekoliko zasebnih, no međusobno proetih cjelina. Nakon uvoda u 2. poglavlju dan je pregled postojeće normizacije i legislative. U 3. i 4. poglavlju opisano je najčeće nazivlje i definicije te prikazan pojmovnik iz područja kvalitete električne energije i elektromagnetske kompatibilnosti. Poglavljem 5. obuhvaćena su poznata saznanja o kontinuiranim i diskretnim smetnjama. U 6. poglavlju analiziraju se podaci dobiveni mjerenjem u NN i SN mrei. Pojedini kontinuirani pokazatelji kvalitete se zdruuju i normaliziraju te se temeljem relevantne znanstveno-stručne literature postavlja metoda i vri proračun jedinstvenog indeksa kvalitete električne energije za ovu vrstu smetnji. Za diskretne smetnje napravljen je pregled sveobuhvatne prakse i predloenih metoda za karakterizaciju diskretnih događaja te proračun indeksa događaja, mjesta mjerenja i sustava. U 7. poglavlju učinjen je proračun tokova viih harmonika i frekvencijska analiza na dijelu EE mree napajane iz jedne TS 110/10 kV. Podaci dobiveni mjerenjem uspoređeni su sa računalnim simulacijama koje su provedene za različita opterećenja nelinearnih tereta u EE mrei.
Abstract (english)
This work has been divided in a several individual but mutually imbued parts. After introduction paragraph the second paragraph, give a review of actual norms and legislation. In third and fourth paragraph the most common terms and definitions were described as well as power quality and electromagnetic compatibility related expression dictionary. Paragraph fifth comprises known facts about continuous and discrete disturbances. In sixth paragraph results of middle voltage network and low voltage network measurements were analyzed. A particular continuous power quality index was grouped and normalized and a one method for calculation of unified power quality index, based on a relevant scientific literature, is established. As for discrete disturbances, a one survey of overall praxis with suggested methods for discrete events characterization and calculation of event index, site index and system index is given. Paragraph seventh covers propagation of harmonics and frequency analysis of a part of power networks feed from a one substation 110/10 kV. Measurement results were compared with computer simulation results. Different electric power levels of nonlinear sources were modeled an also taken in a computer simulations.
