20.500.12556/DKUM-54491 Določanje parametrov nadomestnega vezja in magnetno nelinearne karakteristike enofaznega transformatorja Determining the parameters of equivalent circut and magnetically nonlinear characteristics of one-phase transformer Cilj diplomske naloge je določiti parametre nadomestnega vezja in magnetno nelinearne karakteristike enofaznega transformatorja. Iz meritev prostega teka, kratkega stika in vklopa transformatorja bomo določili parametre nadomestnega vezja. Iz časovnih potekov napetosti in tokov bomo numerično izračunali magnetno nelinearno karakteristiko testnega transformatorja. Iz knjižice SysPowerSystem v Matlab/Simulinku bomo uporabili matematični model enofaznega transformatorja. S primerjavo med izmerjenimi časovnimi poteki in simulacijsko izračunanimi časovnimi poteki bomo ovrednotili dinamični model enofaznega transformatorja. The aim of the diploma work is to determine the parameters of equivalent circuit and magnetically nonlinear characteristics of single-phase transformer. From measurements of no load, short-circuit and switching transformer we will determine the parameters of the equivalent circuit. From time frames voltages and currents we calculate numerically the nonlinear magnetic characteristics of the test transformer. From the booklet SysPowerSystem in Matlab/Simulink, we use a mathematical model of single-phase transformer. By comparing the measured timing and simulation calculated time course will be evaluated dynamic model of single phase transformer.
