Simulation of Dynamic Behavior of Single Phase Transformers in SimPowerSystemu

Transformator je elektriĉki ureĊaj koji pretvara izmjeniĉne napone i struje jednih veliĉina unapone i struje drugih veliĉina. Glavni djelovi transformatora su namoti i jezgra. Transformatorje ekonomiĉan stroj sa jako malo gubitaka. Matlab je multifunkcionalni sloţeni programskisustav te ujedno i programski jezik visoke razine. Za simualciju jednofaznog transformatorakorišten je potprogram SimPowerSystems. Sympowersistems je jedan u nizu software-skin alataza fizikalno modeliranje. Uz pomoć SimPowersystema dobivene su ulazne i izlazne snage,naponi i struje. Nakon mjerenja u tri pogonska stanja transformatora dobiveni su grafovi kojinam opisuju sam transformator. Pogonska stanja transformatora su prazni hod, opterećenje,kratki spoj.Transformer is electrical device that converts electrical voltages and currents of some size involtages and currents of other sizes. Main parts of transformer are windings and the core.Transformer is effective machine whit few casualties.matlab is multifunctional complex softwaresystem and also high level programming language.For the simulation of single-phase transformeris used subroutine of Matlab called SimPowerSystems. Sympowersystem is one of manysoftware tools for physical modeling. Whit the help of Sympowersystems i received input andoutput powers, voltages and currents. After measurements in three operating conditions oftransformer were obtained graphs that describe transformer himself. Three operating conditionsof transformer are idling of transformer, transformer load and short circuit of transforme
