Hydroelectric power plant 2500 W : Hydrelec 2500
This power station is the reduced model of
a hydro-electrical power station driven by
a Pelton turbine. It is composed of all the
components needed to simulate a river with a
penstock pipe and the production of electrical
energy through a Pelton turbine
Didactics hydroelectric plant is geometrically
similar representation of the actual plant. The
hydraulic quantities and electrical powers
are reduced in order to be compatible
with the infrastructure and equipment of
establishments.
The operation, behavior and setting methods
are nevertheless similar to what occurs in the
real system.
The components of the educational system
such as the turbine and generator are directly
from the industrial world and are commonly
used in real micro hydro projects.
This approach allows to users of the system
under actual operating conditions of a micro
hydro.
