AVTOMATION OF OPEN WATER COOLING SYSTEM

V tej diplomski nalogi je opisana avtomatizacija odprtega vodnega hladilnega sistema. V začetku diplomske naloge je opisan celoten sistem in tehnološki opis naprave. Diplomska naloga podaja rešitev avtomatizacije takšnega sistema, ki zajema krmiljenje, regulacijo in nadzor. Krmiljenje je izvedeno s Siemens krmilnim sistemom S7-300 in nadzornim panelom TP270. V vsebini je opisana zgradba krmilnega programa razvitega s programom Step7 in razvojna aplikacija s programom WinCCflexible. Na koncu je podan potek zagonov in optimizacija sistema.This diploma thesis describes the automation of an open water cooling system. The beginning of diploma work describes the entire system and a technological description of the device. Diploma task provides automated solution including feedforward and feedback control, and supervision of the system. The control is carried out with control systems Siemens S7-300 and control panel TP270. The content of the control unit is build with the program Step7 and the development application of the program WinCCflexible. There is a description of startups and system optimization at the end of my work
