| Abstract | Diplomski rad prikazuje realizaciju sustava upravljanja električnim motorima preko
PROFIBUS industrijske sabirnice korištenjem programibilnog logičkog upravljača te dva
frekvencijska pretvarača s pripadnim asinkronim motorima. Frekvencijski pretvarač Sinamics
parametriran je pomoću programskog paketa Starter, dok je frekvencijski pretvarač Simovert
parametriran pomoću programskog paketa Drive Monitor. Rezultati određivanja parametara
nadomjesne sheme asinkronog motora pomoću automatskog parametriranja frekvencijskog
pretvarača uspoređeni su s rezultatima dobivenim matematičkim metodama (pet metoda) na
temelju nazivnih podataka asinkronog motora. Upravljački program za korišteni PLC 300
napisan je u programskom paketu STEP 7. Naredbe (promjena brzine vrtnje, reverziranje,
puštanje u pogon) i algoritmi za upravljanje pogonom ostvareni su pomoću kreiranog
upravljačkog programa. Komunikacija između osobnog računala i PLC-a ostvarena je ethernet
kabelom. HMI sučelje za nadzor i upravljanje realizirano je pomoću programskog paketa WinCC
Explorer, gdje se pomoću grafičkih i tekstualnih prikaza daje uvid u statuse frekvencijskih
pretvarača i pripadajućih asinkronih motora te se omogućava upravljanje istim. Rezultati
upravljanja asinkronim motorima analizirani su pomoću valnih oblika struja, momenta, napona,
frekvencije i brzine vrtnje stroja. Valni oblici snimljeni su pomoći programskog paketa FDA
Configurator. |

| Parallel abstract (English) | This Master thesis shows the implementation of electric motor control systems via
PROFIBUS Fieldbus by using a programmable logic controller and two frequency converters
associated with asynchronous machines. The frequency converter Sinamics and the frequency
converter Simovert are configured by using the Starter and the Drive Monitor software package,
respectively. Parameter results of an induction motor equivalent circuit using auto-tuning of the
frequency converter are compared with the results obtained by mathematical methods (five
methods) based on the nominal data of the induction motor. Software used for the PLC 300 is
written in the STEP 7 programming package. Commands (i.e., speed reference, reversing,
commissioning) and algorithms to control the drives were achieved by using the created
software. Communication between the PC and the PLC is realised via an Ethernet cable. HMI
interface for monitoring and control is achieved by using the WinCC Explorer software package.
Graphical and textual display gives an insight into the status of frequency converters associated
with asynchronous machines and allows their control. Control of induction motors is analysed by
current, torque, voltage, frequency and speed waveforms of the induction motor. Waveforms are
recorded with the FDA Configurator software package. |
