Abstract
Hidroelektrana je postrojenje u kojem se potencijalna energija vode pretvara u kinetičku energiju njenog strujanja, potom u mehaničku energiju vrtnje vratila turbine te konačno u električnu energiju u sinkronom generatoru. Sinkroni generator pretvara mehaničku energiju turbine u električnu energiju. Pogonska stanja sinkronog generatora su prazni hod, opterećenje, kratki spoj, te krajnja stanja otočni rad (rad na vlastitoj mreţi, napajanje samo vlastitih trošila), i paralelni rad (više paralelno spojenih generatora koji imaju konstantan napon i frekvenciju). Da bi napon i frekvencija bili konstanti potrebno je regulirati uzbudnu struju i brzinu vrtnje turbine. Za paralelno priključivanje sinkronog generatora na mreţu potrebno je provesti postupak sinkronizacije za koji je potrebno zadovoljiti sljedeće uvjete: redoslijed faza generatora i mreţe mora biti jednak, iznosi napona, frekvencije i fazni kutovi napona generatora i mreţe moraju biti jednaki. Energetske karakteristike hidroelektrane su: instalirana snaga, maksimalna snaga, raspoloţiva snaga, stupanj djelovanja turbine i generatora, moguća godišnja proizvodnja itd. Te karakteristike se razmatraju da bi se odredila optimalna raspodjela opterećenja meĎu agregatima.
Abstract (english)
The hydroelectric power plant is a plant in which the potential water energy converts into the kinetic energy of its current, then into the mechanical energy of the turbine shaft rotation and ultimately into the electric energy in the synchronous generator. A synchronous generator converts the mechanical energy of the turbine into the electric energy. The synchronous generator operating state is an idle state, load, short circuit, and final operating states are island mode (operation on its own network, stand-alone generators), and parallel mode (parallel generators with constant voltage and frequency). To keep the voltage and frequency constant, it is necessary to regulate the excitation current and turbine speed. For parallel connection of the synchronous generator on a network, it is necessary to perform the synchronization process for which the following conditions have to be met: the order of the generator and network phase must be equal, the voltage levels, the frequency and phase angles of the generator voltage and the network must be equal. The hydroelectric power features are: installed power, maximum power, available power, turbine and generator efficiency, possible annual production, etc. These characteristics are considered to determine optimal load distribution among aggregates
