Abstract

U ovom radu detaljno je opisan princip rada besprekidnih izvora napajanja (UPS-ova) te njihova uloga u velikim sustavima napajanja. S obzirom na način izvedbe, napravljena je njihova podjela te opis odabrane vrste UPS-a. Vrsta komunikacije između PLC-a i UPS-ova je Modbus. Postoji više vrsta Modbusa, ovisno o načinu povezivanja i o strukturi poruke. U ovom radu korišten je Modbus TCP/IP koji je vrsta Modbus komunikacije preko Etherneta. U konačnici, napravljen je softver temeljen na svemu prethodno istraženom, koji omogućava spajanje sedam UPS-ova na jedan centralni PLC te prikaz podataka s UPS-a na jednom zajedničkom nadzorno upravljačkom sustavu (SCADA). Da bi se potvrdila funkcionalnost softvera, napravljen je niz simulacija kao i testiranje na samim uređajima.

Abstract (english)

This paper describes main principles of uninterruptible power supplies (UPSs) and their role in big power supply systems. Considering ways of constructions, they are separated in few groups. In this project, communication protocol between PLC and UPSs is Modbus. There are different types of Modbus depending on way of establishing communication and message structure. In this work, type is Modbus TCP/IP, which is the type of communication over the Ethernet. After all, software for connecting seven UPSs to one central PLC is made and described, so as supervisory control and data acquisition on central SCADA. Different simulation softwares are used to test the functionality of software before testing on UPSs.
