Abstract:
Diplomsko delo obravnava dva načina zagona asinhronskega elektromotorja. V prvem delu smo za mehki zagon motorja uporabili napajalnik ALTISTART 3. V drugem delu pa smo za mehki zagon uporabili frekvenčni pretvornik COMBIVERT 56. Meritve smo izvedli pri različnih obremenitvah motorja. Za obremenitev motorja smo uporabili aktivno breme sestavljeno iz asinhronskega stroja in frekvenčnega pretvornika. Cilj diplomske naloge je bil izdelati program za harmonično analizo meritev in analizirati vhodni tok, tok v motor, napetost na motorju in moment motorja. Program za analizo in izrise je napisan v MatLab-u. Vse meritve v zvezi z diplomsko nalogo so bile izvedene v Laboratoriju za aplikativno elektromagnetiko na Fakulteti za elektrotehniko, računalništvo in informatiko v Mariboru.

Title:
HARMONIC ANALYSIS OF VOLTAGE AND CURRENT FOR SOFT START OF INDUCTION MOTOR
Abstract:
The diploma thesis deals with two ways to start induction motor. In the first part we used power supply ALTISTART 3 for soft start of electric motor. In the second part we used frequency converter COMBIVERT 56 for the same start. All measurements were made with different load of a motor. For motor load we used active load which was composed from induction motor charging from frequency converter. The goal of this diploma thesis was to make a program for harmonic analysis of measurements and to analyse input current, current into the motor, motor voltage and motor torque. The program for the analysis and plots is written in MatLab. All work connected with this diploma thesis has been done in the Applied Electromagnetics Laboratory of the Faculty of Electrical Engineering and Computer Science in Maribor.
