20.500.12556/RUL-139606 Nadzorni sistem in krmiljenje asinhronskih motorjev SCADA system and induction-motor control Cilj naloge je narediti nadzorni sistem, ki vključuje uporabo programirljivega logičnega krmilnika (PLK) (ang. programmable logic controller - PLC) in frekvenčnega pretvornika za krmiljenje asinhronskega motorja. Nadzorni sistem bo omogočal spremljanje stanja naprav v sistemu, spreminjanje parametrov delovanja motorjev, preklapljanje med ročnim in avtomatskim načinom delovanja in pa odkrivanje morebitnih napak v sistemu. V diplomski nalogi so v prvem delu opisane vse komponente sistema, ki je narejen na demonstracijskem panelu. Predstavljeno je, kako se vzpostavi povezava med PLK-jem znamke Siemens in frekvenčnim pretvornikom proizvajalca ABB. Povezava je vzpostavljena preko protokolov PROFIBUS in PROFINET, ki sta med najpogosteje uporabljenimi komunikacijskimi protokoli v industriji. V nadaljevanju je opisan primer uporabe frekvenčnega pretvornika in upravljanje sistema preko nazornega sistema Siemens SIMATIC WinCC V7. Nadzorni sistem operaterju omogoča komunikacijo s strojem in s tem nadzor nad procesom. Poleg tega pa tudi hrani in obdeluje podatke in sporoča sistemske napake. V diplomski nalogi je prikazno, kako se uvozi spremenljivke s krmilnika v nadzorni sistem Siemens SIMATIC WinCC V7, kako se barva ikone glede na vrednosti spremenljivk sistema (stanje sistema), odpiranje oken za upravljanje naprave in prikaz alarmov. Menim da je naloga uspela, saj sistem izpolnjuje zastavljene zahteve delovanja, ki si bile navedene v poglavju 2.1.V šestem poglavju lahko vidimo da se ikone pravilno barvajo glede na stanje sistema in da nas v primeru napake nazorni sistem obvesti. Naloga je primerna za učenje začetnikov v avtomatiki, saj opisuje izdelavo nadzornega sistema, ki vključuje uporabo PLK-ja in frekvenčnega pretvornika za krmiljenje asinhronskega motorja. The aim of the task is to make a control system that includes the use of a programmable logic controller (PLC) and a frequency converter to control an induction motor. The control system will enable monitoring of the condition of devices in the system, changing the parameters of engine operation, switching between manual and automatic mode and detecting possible faults in the system. In the first part, the diploma thesis describes all the components of the system made on the demonstration panel. It is presented how to establish a connection between a Siemens PLC and an ABB frequency converter. The connection is established via the PROFIBUS and PROFINET protocols, which are among the most commonly used communication protocols in the industry. The following is an example of using a frequency converter and operating the system via the Siemens SIMATIC WinCC V7 demonstration system. The control system allows the operator to communicate with the machine and thus control the process. In addition, it also stores and processes data and reports system errors. The diploma thesis shows how to import variables from the controller into the Siemens SIMATIC WinCC V7 control system, how to color the icon according to the values of system variables (system status), open device management windows and display alarms. I think that the task was successful, because the system meets the set operating requirements, which were stated in section 2.1. In the sixth chapter we can see that the icons are colored correctly according to the state of the system and that in case of error the visual system informs us. The task is suitable for beginners to learn in automation, as it describes the construction of a control system that includes the use of a PLC and a frequency converter to control an induction motor. programirljivi logični krmilnik asinhronski motor nadzorni sistem programsko orodje TIA Portal Siemens SIMATIC WinCC V7 programmable logic controller asynchronous motor SCADA Program tool TIA Portal Siemens SIMATIC WinCC V7 true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2022-09-05 14:50:00 2022-09-05 14:50:07 2022-09-16 04:11:21 0000-00-00 00:00:00 2022 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 57601 120307971 Zorman_Miha_-_Nadzorni_sistem_in_krmiljenje_asinhronskih_motorjev.pdf Zorman_Miha_-_Nadzorni_sistem_in_krmiljenje_asinhronskih_motorjev.pdf 1 31B3142E07080C4BA5930A02F99259B5 64529d09ccb68d4e64615e672b2c095874bd0b8b1545604ba0e33a2c52f79bba 3957d66b-2d19-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=160192 Fakulteta za elektrotehniko 0 0 0
