Abstract
Ovim diplomskim radom definirana je kvaliteta električne energije i njeni mjerljivi pokazatelji. Pobliže je opisan problem strujnih i naponskih harmonika koji u suvremeno doba postaje sve veći. Opisan je pojam nelinearnog trošila koji uzrokuje nastanak harmonika. Također, opisana je matematička analiza i navedeni su izvori harmonika i posljedice koje njihovo prisustvo u mreži uzrokuje. Nadalje, napravljen je pregled aktualnih normi bitnih za definiranje sigurnih razina harmonika u mreži. Date su metode za ublažavanje utjecaja harmonika od kojih je najvažnija ugradnja aktivnog filtera. Aktivni filteri podijeljeni su prema nekoliko kriterija, te su opisane njihove razlike i način rada. Na posljetku je provedeno ispitivanje rada aktivnog filtera u zgradi fakulteta uz pomoć generatora harmonika kojim je simulirano više trošila s različitim karakterističnim spektrima. Izmjerene vrijednosti analizirane su i donesen je zaključak o primjeni aktivnog filtera za filtriranje harmonijskih struja i napona.
Abstract (english)
This master’s thesis defines the quality of electrical energy and its measurable indicators. The issue of current and voltage harmonics, which is becoming increasingly significant in modern times, is described in detail. The concept of a nonlinear load, which causes the occurrence of harmonics, is explained. Additionally, a mathematical analysis is presented, along with sources of harmonics and the consequences of their presence in the network. Furthermore, an overview of current standards relevant to defining safe harmonic levels in the network is provided. Methods for mitigating the impact of harmonics are given, with the installation of an active filter being the most important. Active filters are categorized based on several criteria, and their differences and modes of operation are described. Finally, an examination of the active filter's performance in a university building was conducted using a harmonic generator, simulating multiple loads with different characteristic spectra. The measured values were analyzed, and conclusions were drawn regarding the application of the active filter for filtering harmonic currents and voltages.
