The diagram below shows how electricity is generated in a hydroelectric power station. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates the process of generating
electricity
in a hydroelectric power
station, which operates differently during the day and night. During the day, water
flows from a high-level reservoir
through a dam to generate electricity
, while
at night, water
is pumped back from a low-level reservoir
to the high-level reservoir
for reuse.
In the daytime, water
is released from the high-level reservoir
through an intake that remains open. The water
flows downhill to the power
station, where it turns reversible turbines, generating electricity
. This
electricity
is then
transferred to the national grid via power
lines. After passing through the turbines, the water
is stored in a low-level reservoir
.
At night, the process is reversed. The intake is closed, and the turbines are used to pump water
from the low-level reservoir
back to the high-level reservoir
, ensuring that the system is ready to produce electricity
again during the day. This
cyclical process allows for continuous power
generation.Submitted by d.adeliasong on
