Procesni sustav HE Dubrava

Ovim radom želi se prikazati sustav Hidroelektrane Dubrava te način na koji on funkcionira. Stoga, ovaj rad, u svojoj suštini, prolazi kroz tehničke podatke glavnih dijelova strojarnice, same brane, procesne sustave te operatorsku stanicu. Naglasak rada je više na opisivanju sustava koji su potrebni da bi Hidroelektrana vršila svoju zadaću. Rad je koncipiran u nekoliko cjelina. U uvodu je ukratko opisana Hidroelektrana Dubrava, njezina lokacija, veličina te povijest izgradnje. U drugoj cjelini opisana je uloga komande lanca Varaždin koja obavlja daljinski nadzor i upravljanje hidroelektranama na Dravi s ciljem što boljeg iskorištenja voda, a u skladu s upravljanjem vodama u Hrvatskoj. U trećoj cjelini donose se osnovni tehnički podaci glavnih dijelova strojarnice kao što su proizvodne jedinice, upravljanje, signalizacija proizvodne jedinice, mjerenja. Četvrta cjelina donosi prikaz osnovnih tehničkih podataka glavnih dijelova brane. U petoj cjelini donosi se prikaz procesnog sustava Hidroelektrane, a u šestoj cjelini upoznajemo način rada Operatorske stanice. Sedma cjelina bavi se listom događaja i alarma, a osma prikazom ulaza i izlaza. Možemo zaključiti da je Hidroelektrana Dubrava višestruko korisna jer koristi potencijal rijeke Drave za proizvodnju električne energije, ujedno povećava zaštitu od poplava, poboljšava odvodnju, omogućuje gravitacijsko natapanje poljoprivrednih površina te omogućuje uvjete za razvoj sporta i rekreacije.This paper will show the hydro-electric power plant Dubrava's system and the way it works. Therefore, this paper, in its essence, is going through the technical details of the main parts of the turbine hall, the dam itself, process systems and the Operator's station. The emphasis of the paper is on the description of the systems that are necessary for the hydro-electric power plant to carry out its task. The work is divided into several sections. The introduction briefly describes the hydro-electric power plant Dubrava, its location, size and history of its construction. The second part describes the role of the command chain Varazdin that performs remote monitoring and management of hydro-electric power plants on the Drava with the aim of better utilization of water, and in accordance with the water management requirements in Croatia. Third section covers the basic technical specifications of the main parts of the turbine hall, such as the production units, operation, signalling of production unit and measurements. The fourth section provides an overview of key technical data of the main parts of the dam. The fifth section displays the process system of the hydro-electric power plant, and the sixth sections introduces the workings of the Operator's station. The seventh section deals with the list of events and alarms, and the eighth displays various inputs and outputs. It can be concluded that the hydro-electric power plant Dubrava is highly beneficial because it uses the potential of the Drava river to generate electricity. Further, it increases flood protection, improves drainage, enables gravitational irrigation of agricultural land and provides conditions for the development of sport and recreation
