Power Quality - Flickers

U sklopu ovog diplomskog rada opisan je problem naponskog treperenja. Opisani su izvori i posljedice naponskog treperenja, opisana je europska norma EN 50160, rasprostiranje naponskog treperenja u nekoj točki mreže i metode ublažavanja naponskog treperenja. U radu se osim detaljnog teoretskog opisa problema naponskog treperenja nalazi i analiza rezultata mjerenja naponskog treperenja u kotlovnici postrojenja za preradu drva. Mjerenje naponskog treperenja u kotlovnici postrojenja za preradu drva je obavljeno Flukeovim uređajem 1745 Power Quality Logger a analiza je napravljena na računalu u programu PQ Log. Analizom mjerenja naponskog treperenja nisu utvrđeni razlozi naponskog treperenja u kotlovnici, ali su određene metode ublažavanja naponskog treperenjaIn this study the problem of voltage fluctuations is described. The sources and effects of voltage fluctuations, the European standard EN 50160, Propagation of voltage fluctuations at some point in the network and methods of mitigating voltage fluctuations are described. The study except a detailed theoretical description of the problem of voltage fluctuations contains of analysis of measurement of voltage fluctuations in the boiler plant for in plant for wood processing. Measurement voltage fluctuations in the boiler plant is done device by Fluke 1745 Power Logger, and the analysis is made on the computer in the program PQ Log. The analysis of the measurements of voltage fluctuations not identify the main sources of voltage fluctuations in the boiler room, but are determine methods to mitigate voltage fluctuations are determined
