Start up of hydro power plant

U ovom diplomskom radu prikazana je podjela hidroelektrana te su opisani njeni osnovni dijelovi. Opisane su hidrološke karakteristike, karakteristike akumulacije pada te energetske karakteristike hidroelektrana. Pomoću karakteristika hidroelektrane se odabire prikladna turbina. U radu je također prikazan pregled postupka puštanja hidroelektrane u pogon. Prikazana su ispitivanja koja se vrše prilikom pokretanja agregata i njegovog puštanja u pogon. Jedna od glavnih ispitivanja su prva mehanička vrtnja turbine, zalet generatora do nazivne brzine te nagli ispad generatora. Navedene su klase generatora s obzirom na njihovu veličinu te je dan popis ispitivanja koja se vrše u tvornici i na terenu za svaku klasu. Osim generatora, prikazana su ispitivanja koja se vrše na blok-transformatoru elektrane. Na kraju rada su dane standardne sheme relejne zaštite za male hidroelektrane, te za srednje i velikeThis graduate thesis is provides classification of hydro power plan and describes its basic parts. Thesis also shows hydrological characteristics, the accumulation characteristics, and the energy characteristics for hydro power plant. Based on those characteristics, a suitable turbine is selected. The thesis also provides an overview of te process of commissioning and start-up of the hydro power plant. One of the main tests are the first rotation of the turbine, run of the generator to rated speed and load rejection test. In paper are shown the generator classes in terms of their size, and a list of factory tests and field test carried out for each class. In addition to the generator, the step-up transformer factory test and field test, are presented. In final chapter are illustrated some of the standard protective relay shemes for small hydro plants, and for large electrical equipment located in medium and lagre hydro power plants
