O hidrocentrala este o centrala electrica folositpentru a transforma energia mecanica produs

de apa n energie electrica.

Tipuri de hidrocentrale

cu o cadere mica de apa - < 15 m, debit mare;

cu o cadere mijlocie - 1550 m, cu debit mijlociu;

cu o cadere mare 502.000 m, cu un debit micde apa.

Generatoare

Tipuri de generatoare:

Generatoare sincrone= masina de curentalternativ la care turatia motorului este egala

cu cea a campului invartitor, indiferent desarcina.

Generatoare asincrone= orice masina decurrent alternativ, care la frecventa data a

retelei, functioneaza cu o turatie variabila cu

sarcina.

Turbine hidraulice

DefinitieO turbinhidraulic este o masina de for care transform energia hidraulica (a apei)

n energie mecanic prin intermediul unui rotor prevzut cu palete.

O turbin este format din:

Stator, n care energia primar (energia potenial n cazul fluidelor incompresibile,respectiv energia internn cazul fluidelor compresibile) este transformat n energiecinetic.

Rotor, format dintr-unul sau mai multe discuri echipate cu palete, discuri fixate pe unarbore, cu care se rotesc solidar.

Tipuri de turbine hidraulice:-Turbina Pelton-Turbina Francis-Turbin Kaplan-Turbina Bulb

-Turbina Michell-Banki
