The use of the supervisory control systems for remote control of Hydropower plants

U radu se nalaze opisani sustavi daljinskog upravljanja u hidroelektranama, kod kojih vrh upravljačke strukture predstavlja SCADA programska aplikacija. Tako su predstavljeni principi rada SCADA aplikacije, te urađen kraći pregled dva SCADA programska paketa. Posebno su opisani uvjeti koji moraju biti zadovoljeni kod izrade SCADA sustava za hidroelektranu, kao i naglašene komponente koje mora sadržati SCADA programski paket za izradu aplikacije za nadzor hidroelektrane. Detaljno je obrađen sustav daljinskog upravljanja HE “Miljacka” na rijeci Krki, sa prikazanim podsustavima i opisanim načinom rada. Na kraju je dan osvrt na sustav i njegove prednosti, te nedostatke. Dalje je prikazana SCADA u sustavu regulacije grupne snage triju elektrana sliva rijeke Drave. Završno je izveden pregled mogućnosti primjene SCADA sustava za zadaću nadzora U-Q regulacije EES-a, od lokalnih jedinica, pa do EES-a na razini države.Work presents supervisory control systems for remote control of Hydropower plants, in which is SCADA application the top of the control structure. So was presented the basics of SCADA work and given a short description of two SCADA packages. Separately was mentioned conditions which must be fulfiled by building a SCADA system for Hydropower plant, as well as the components which must be a part of a SCADA programming package used for building an application for Hydropower plant control. There was presented in detail the remote control system built in HPP “Miljacka” on river Krka, with all subsystems and description of work. In the end was given remark on the system and its advantages and disadvantages. Further was presented a SCADA in the system of a group power control on three HPPs on stream of the Drava river. Finally, the use of a SCADA system in the U-Q control of electric distribution system was presented, from local units till the electric distribution system on the state level
