Abstract

U prvom dijelu ovog diplomskog rada opisani su način rada i osnovni dijelovi
frekvencijskog pretvarača VLT Automation Drive FC302. U nastavku je dana
usporedba dviju inačica funkcije za identifikaciju parametara motora
potkrijepljena mjerenjima napona i struja u laboratoriju na fakultetu. Glavni dio
rada bavi se analizom četiriju struktura upravljanja implementiranih u ovaj tip
frekvencijskog pretvarača, s posebnim naglaskom na VVCplus način
upravljanja. Opisane su blokovske strukture upravljanja, dane su usporedbe
vezane za dinamiku upravljanja i provedena su mjerenja struja i napona u
laboratoriju. U zadnjem dijelu rada opisan je postupak integracije
frekvencijskog pretvarača u nadređeni sustav upravljanja putem PLC-a i izrada
HMI sučelja za korisnika. Provedene laboratorijske vježbe opisuju osnovne
korake bitne za uspješno parametriranje i puštanje u rad, tipične primjene u
industriji i realiziranje složenijih zahtjeva pomoću Smart Logic i Scope funkcije.

Abstract (english)

The first part of this master thesis presents work principles and basic parts VLT
Automation Drive FC302 frequency converter. Next chapter is about
comparison between two versions of automatic motor adaptation (AMA)
function, supported by measurements in the laboratory. The main part of this
thesis is about the analysis of four control algorithms implemented in this
frequency converter, especially VVCplus control algorithm. Control algorithms
block structures are described, comparison of control dynamics is shown and
laboratory measurements are conducted. The last chapter presents the
integration of frequency converter into master control structure with PLC and
creating HMI user interface. Laboratory exercises describe basic steps for
succesfull parametrization and commisioning, typical industry applications and
solving more complex tasks using Smart Logic Controller.
