and blocked by a dam.In the first stage,the intake,which is at the bottom of the dam,will open to let

water

flow into the reversible

turbines

.

Following

this

,the

water

flow makes the

turbines

rotate and drive the generator to work,which is on the top space of the

power

station.In the final stage,the

power

lines will transport the

electricity

conducted by the generator to the National grid. When it comes to the night,the

water

stocked in the low-level

reservoir

will be pumped back into the high-level

reservoir

by the reversible

turbines

through the same tubes.Subsequent to
