DIMENZIONIRANJE VODNE KOMORE U DOVODNOM SUSTAVU HIDROELEKTRANE

Rad se sastoji od nekoliko dijelova. U prvom dijelu se nabrajaju dijelovi hidrauličkog sustava hidroelektrane i opisuju vrste vodnih komora. U drugom dijelu se opisuju gubici strujanja u dovodnom tunelu i tlačnom cjevovodu, razlozima zbog kojih do gubitaka dolazi i načinu na koji se računaju. U trećem dijelu određuju se dimenzije vodne komore. U posljednjem poglavlju prikazane su tranzijentne pojave u tlačnom sustavu u ovisnosti o promjeni opterećenja i upuštanju u rad.This thesis is divided into several parts. In the first part, the elements of hydraulic machinery of hydroelectric power plant are enumerated and the types of surge tanks are described. In the second part, head losses in the pressure tunel and in the penstock are discussed, the reasons why they occur and the way in which they are calculated. In the third part, the dimensions of a sruge tank are defined. In the last chapter, the graph of transient occurrences in hydraulic system is showing the dependence of a change in pressure when the turbine is starting to work
