Pretul de cost al unui hidrogenerator este sensibil influentat de parametrii constructivi adoptati sau calculati.
Cele mai importante variabile care intervin in proiectarea generatorului sincron destinat microhidrocentralelor, sunt patura
de curent, densitatea de curent din infasurarea statorica si marimea intrefierului. In lucrare s-a analizat, influenta
variabilelor mentionate asupra costului generatorului sincron, pentru hidrogeneratoare avand aceeasi putere dar cu turatii
diferite. Concluziile rezultate ofera informatii esentiale pentru etapa de proiectare a hidrogeneratoarelordestinate MHC.

Abstract
A hydrogenerator’s cost price is considerably influenced by the used and computed design values. The most
important parameters in the design of micro hydro power plants synchronous generators are the power blanket, the current
density in the statoric winding and the air gap size. In this work we analyze the impact of these parameters on the cost
price for a family of hydro power plant synchronous generator where the power is the same but the rotations vary. The
conclusions we take offer information essential to the design phase of these micro hydro power plant hydrogenerators.
