Abstract
Hibridni kao i električni pogon su ekološki prihvatljivija rješenja u usporedbi s konvencionalnim pogonom, a s obzirom na ograničene zalihe nafte, postaju sve popularniji. Stoga, je upravo hibridni pogon razmotren u ovom radu, točnije razmotrene su komponente energetske elektronike za hibridni šumski traktor s naglaskom na integraciju visokonaponskog i niskonaponskog energetskog sustava. U radu je dan pregled energetske elektronike za hibridna vozila te je predstavljen izbor svih komponenti potrebnih za hibridizaciju razmatranog vozila. Provedena je analiza troškova kako bi se odredila isplativost takve investicije. Nadalje, kao rješenje za integraciju visokonaponskog i niskonaponskog energetskog sustava predstavljen je paralelni rad više silaznih DC pretvarača. Također je predložen hijerarhijski sustav upravljanja radom pretvarača koji obuhvaća primarnu, sekundarnu i tercijarnu regulaciju. Rad takvog sustava ispitan je simulacijski i eksperimentalno. Rad je koncipiran u nekoliko poglavlja. U uvodu je ukratko opisana problematika rada. U drugom poglavlju nalazi se pregled značajki šumskog traktora. Treće poglavlje daje pregled energetske elektronike koja se koristi za hibridna vozila te komponenti koje su izabrane za razmatrani traktor. Četvrto poglavlje odnosi se na analizu troškova, a peto na rješenje za integraciju visokonaponskog i niskonaponskog energetskog sustava. Šesto poglavlje opisuje računalni model pretvarača. U sedmom poglavlju predstavljeno je rješenje za regulaciju paralelnog rada pretvarača, a osmo poglavlje sadrži eksperimentalne rezultate. Na kraju je dan osvrt na diplomski rad u cjelini.
Abstract (english)
Hybrid as well as electric propulsion are more environmentally friendly solutions compared to conventional propulsion, and given the limited oil reserves, they are becoming more popular. Therefore, the hybrid propulsion is considered in this paper, more specifically the components of power electronics for a hybrid forest tractor with emphasis on the integration of high voltage and low voltage power system. The paper gives an overview of power electronics for hybrid vehicles and presents a selection of all components required for hybridization of the considered vehicle. A cost analysis was conducted to determine the profitability of such an investment. Furthermore, as a solution for the integration of high-voltage and low-voltage power systems, the parallel operation of several buck DC converters is presented. A hierarchical control system of converter operation is also proposed, which includes primary, secondary and tertiary regulation. The operation of such a system was examined through the simulation and experimentally. The paper is conceived in several chapters. The introduction briefly describes the issues of work. The second chapter provides an overview of the characteristics of a forest tractor. The third chapter provides an overview of the power electronics used for hybrid vehicles and the components selected for the considered tractor. The fourth chapter deals with cost analysis, and the fifth with a solution for the integration of high-voltage and low-voltage energy systems. Chapter six describes the computer model of the converter. The seventh chapter presents a solution for regulating the parallel operation of the inverter, and the eighth chapter contains experimental results. At the end, a review of the thesis is given.
