Abstract
U disertaciji je predložena metoda za pouzdano otkrivanje kvara rotora trofaznog kaveznog asinhronog motora. Metoda je zasnovana na identifikaciji obeležja kvara rotora iz signala terminalnih veličina jednofazno napojenog trofaznog kaveznog motora u stacionarnom stanju pogona. Predložena metoda eliminiše potrebu za postojanja opterećenja motora, što je osnovna prednost u odnosu na rešenja iz literature. Sva teorijska razmatranja su praćena odgovarajućim rezultatima računarskih simulacija, da bi se potom sprovela eksperimentalna verifikacija i potvrdila efikasnost predložene metode. Takođe, predstavljen je postupak za kvantitativnu procenu oštećenja štapnih provodnika rotora.
In this Doctoral dissertation, a novel method for broken rotor bar fault detection in a three-phase squirrel-cage induction motor (IM) is introduced. The proposed method is non-invasive and it is based on the analysis of the IM terminal quantities in a single-phase steady-state operating condition. Compared to conventional fault detection techniques, the developed method does not require any loading on the motor, which is the main benefit of the method. The faulty condition of broken rotor bars was investigated analytically, while the effectiveness of the proposed method was proven by the variety of computer simulations and experimental results. Based on these results, a methodology for the quantification of broken rotor bars in the IM has been presented.
