20.500.12556/RUL-187558 NAPREDNI SISTEM ZA DOLOČANJE IN ANALIZO NAPAK NA TRIFAZNIH SISTEMIH ADVANCED SYSTEM FOR FAULT DETECTION AND ANALYSIS IN THREE-PHASE SYSTEMS Pričujoče magistrsko delo je nadaljevanje razvoja vezja za ugotavljanje napak na trifaznih sistemih. Že na dodiplomskem študiju smo se s to temo ukvarjali in pripeljali razvoj do te točke, da lahko sočasno zajemamo signale napetosti in tokov. Tema magistrskega dela predstavlja nadaljevanje tega razvoja, pri čemer je njen cilj cel sistem popeljati na višjo raven, od koder se lahko integrira v proizvodnjo. Kot je bilo že prej omenjeno, vezje zajema signale napetosti in tokov ter na njihovi podlagi določi, ali sistem deluje pravilno. Vezje meri tri napetostne kanale in tri tokovne kanale, saj je namenjeno diagnostiki trifaznih sistemov. Za vzorčenje signalov skrbi mikrokrmilnik, podatke najprej digitalizira, obdela, razdeli na koščke in nato posreduje računalniku. Računalnik potem te podatke sestavi nazaj v originalne vrednosti, jih obdela in na koncu uporabniku prikaže trenutno stanje stroja. This master thesis is a continuation of the development of a circuit for detecting errors in three-phase systems. We have already been working on this topic during our undergraduate studies and have brought the development to the point where we can simultaneously capture voltage and current signals. The topic of this master thesis is to continue development and take the entire system to a higher level from where it can be integrated into production. As mentioned earlier, the circuit captures voltage and current signals and based on them, determines whether the system is working properly. The circuit measures three voltage channels and three current channels, as it is intended for diagnosing three-phase systems. The microcontroller is responsible for sampling the signals, first digitizing the data, processing it, dividing it into pieces and then transmitting it to the computer. The computer then assembles this data back into its original values, processes it and finally displays the current state of the machine to the user. trifazni motorji razsmerniki računalniško vodeni stroji digitalni filtri hitra Fouriereva transformacija STM32 Raspberry Pi three-phase motors inverters computer-controlled machines digital filters fast Fourier transform STM32 raspberry Pi true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-09-11 11:00:03 2026-09-11 11:00:12 2026-09-14 03:32:16 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 63426 Lokar_Teo_-_NAPREDNI_SISTEM_ZA_DOLOCANJE_IN_ANALIZO_NAPAK_NA_TRIFAZNIH_SISTEMIH.pdf Lokar_Teo_-_NAPREDNI_SISTEM_ZA_DOLOCANJE_IN_ANALIZO_NAPAK_NA_TRIFAZNIH_SISTEMIH.pdf 1 3176EEB340B42DB713B198C76399E4B8 f973b88e2f50c07ba403a394955509036a2d9668180447dd31b6bf1cd06bc9a8 3179a327-adbf-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=247233 Fakulteta za elektrotehniko 0 0 0
