Abstract
Ciklokonverter je jedan od najzastupljenijih pretvarača frekvencije koji je djelovanjem i obilježjima opisan u ovom radu. Za bolje razumijevanje problematike rada, prvo je definirana električna energija, elementi njezine kvalitete i standardizirane norme koje propisuju klasifikacijska društva. Zatim su objašnjeni principi rada statičkih pretvarača frekvencije i vrste koje se najviše koriste u sustavu brodske elektropropulzije. Glavni dio rada je posvećen samom opisu rada ciklokonvertera u blokirnom spoju i s kružnom strujom. Naglasak je najviše stavljen na harmonična izobličenja u elektroenergetskoj mreži i elektromotoru koja nastaju posljedičnim radom ovog pretvarača. Uz to, napravljena je i analiza rezultata rada pomoću simulacijskog modela u programskom paketu Matlab/Simulink iz koje se jasno vidi utjecaj viših harmonika u frekvencijskom spektru mrežnog i izlaznog napona i struje pri različitim izlaznim frekvencijama.
Abstract (english)
Cycloconverter is one of the most common frequency converters, which is described in this thesis by its action and characteristics. To better understand the problems of its impact, first and foremost, electricity, its quality elements and standardized norms prescribed by classification societies are first defined. Then, the principles of operation of static frequency converters and the types that are most used in the ship's electro-propulsion system are explained. The main part of the thesis is dedicated to the description of the operation of cycloconverters in blocking mode and with circulating current. Emphasis is placed most on the harmonic distortions in the power grid and the electric motor that result from the consequent operation of this converter. In addition to this, an analysis of the work results was made using a simulation model in the Matlab / Simulink software package, which clearly shows the influence of higher harmonics in the frequency spectrum of input and output voltage and current at different output frequencies.
