Abstract

U završnom radu je analiziran pogon dizala. U tom slucaju je skladištenje regenerativne energije temeljeno na superkondenzatoru gdje je spoj spremnika energije i istosmjernog međukruga ostvaren preko dvosmjernog DC/DC pretvarača. Detaljno je analiziran princip rada istosmjernih pretvaraca za različta trošila za koja su snimljeni odzivi na laboratorijskom postavu. Simulacijski model sustava za pogon dizala izrađen je u MATLAB Simulinku iz čije je biblioteke preuzet model pogona sa sinkronim motorom s permanentnim magnetima. Model je nadograđen kako bi predstavljao sustav dizala. Upravljanje sklopkama istosmjernog pretvarača ostvareno je upotrebom PI regulatora.

Abstract (english)

In this thesis, an elevator drive with a supercapacitor-based regenerative energy storage system is analyzed. In this case, the energy storage is connected to the DC-link through a bidirectional DC / DC converter. The operation of the DC/DC converter is analyzed for different loads for which the tests were performed in the laboratory setup. The simulation model of elevator drive system was developed in MATLAB Simulink and the drive model with synchronous motor with permanent magnets was taken from MATLAB library. The model was extended to represent an elevator system. The DC/DC converter is controlled by a PI controller.
