20.500.12556/RUL-107904 Nadzorni sistem za energetsko varčno obratovanje sistema ogrevanja, prezračevanja in klimatizacije Supervisory system for energy efficient operation of heating, ventilation and air conditioning system Magistrsko delo se osredotoča na predstavitev razvoja in delovanja nadzornega sistema (ang. supervisory, control and data aquisition, s kratico SCADA) za vodenje in nadzor procesov sistema ogrevanja, prezračevanja in klimatizacije (ang. heating, ventilation, and air conditioning system, s kratico HVAC), razvitega v sodelovanju s podjetjem Metronik d.o.o. Cilj in namen magistrskega dela je bralcu na razumljiv način predstaviti glavne vidike vodenja sistema HVAC, razvoja funkcij vodenja in nadzora ter uporabo sistema SCADA za nadzor industrijskih procesov. V prvem delu magistrskega dela je vključena predstavitev ključnih fizikalnih vidikov sistema HVAC, opis njegovih osnovnih elementov, ki so členi v procesu ogrevanja, prezračevanja in klimatizacije ter predstavitev funkcionalnosti sistema HVAC kot celote. Ker delovanje sistema HVAC pri večjih industrijskih zgradbah ni ekonomično, usklajeno in optimirano brez ustreznega avtomatskega vodenja ter nadzornega sistema, se je zaradi potrebe po nadzoru dogodkov, vodenju procesov in arhiviranju zajetih podatkov ter njihove analize na objektu postavil nadzorni sistem SCADA, katerega osnovni pojmi, funkcionalnost, osnovni gradniki (gradniki sistema vodenja, komunikacijska infrastruktura) in arhitektura so predstavljeni v nadaljevanju splošnega opisa sistema. Drugi del magistrskega dela se osredotoča na podrobnejšo predstavitev razvitega krmilno-regulacijskega nivoja, izvedenega s programirljivimi logičnimi krmilniki (s kratico PLK) proizvajalca GE Automation, kar zajema predstavitev delovanja krmilnikov PLK in opis razvitega krmilniškega programa za potrebe vodenja. Podrobneje je predstavljen tudi razvoj in delovanje nadzornega sistema SCADA, postavljenega na centralnem nadzornem računalniku ter uporabniški vmesnik za nadzor na panelih na dotik Weintek. Magistrsko delo vsebuje tudi predstavitev načina dokumentiranja sistema po smernicah dobre avtomatizirane proizvodne prakse, kar omogoča boljši nadzor nad razvojem in funkcionalnostjo sistema ter končno testiranje in validacijo nadzornega sistema. The thesis focuses on the presentation of the development and operation of the supervisory, control and data acquisition system (SCADA) for the supervisory and control of the processes of heating, ventilation and air conditioning (HVAC) developed in cooperation with company Metronik d.o.o. The objective and purpose of the project is to present the main aspects of HVAC system control, development of supervisory and control functions and the use of the SCADA system in a comprehensible way. The first part of the work includes the presentation of the key physical aspects of the HVAC system, a description of its basic elements that are part of the heating, ventilation and air conditioning process and the presentation of the functionality of the HVAC system as a whole. Since the operation of the HVAC system in large industrial buildings is not economical, harmonized and optimized without proper automation and control system, the SCADA system is installed at the facility due to the need for process control, event monitoring, archiving of captured data and data analysis. The SCADA system basic concepts, functionality, basic elements (sensors, actuators, communication infrastructure) and architecture is presented in the general description of the system. The second part of the work focuses on a detailed presentation of the developed control level of the system, implemented with programmable logic controllers (PLC) of company GE Automation, which includes the presentation of the operation of PLC controllers and a description of the developed control program. The second part also includes a detailed description of the development and operation of the SCADA system installed on the central control computer and description of the user interface for Weintek touch panels. The thesis also includes a description of documentation methods based on the guidelines of good automated manufacturing practice (GAMP), which results in better control of the development and functionality of the system, and better control on the final testing and validation of the control system. sistem SCADA sistem HVAC vodenje nadzor uporabniški vmesnik programirljivi logični krmilnik podatkovna baza SCADA system HVAC system control supervisory human machine interface programmable logic controller database true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2019-06-04 08:46:11 2019-06-04 08:46:19 2022-08-20 03:43:29 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 45701 Gorencic_Gregor_-_Nadzorni_sistem_za_energetsko_varcno_obratovanje_sistema_ogrevanja,_prezraceva.pdf Gorencic_Gregor_-_Nadzorni_sistem_za_energetsko_varcno_obratovanje_sistema_ogrevanja,_prezraceva.pdf 1 AC1F468F787E0C64D90446FDAC1E8669 4185e7de058a29704dae5c2ee9beb244b9fa2cfafbe7357797a83d282b188405 8853fc3d-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=118796 Fakulteta za elektrotehniko 0 0 0
