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 generated electricity by using
water
energy through the hydroelectric power
station.
Overall
, the processing of generated electricity is divided into 5 stages and two different periods which are daytime and nighttime. During the day water
flows from a high-level to a low-level reservoir. However
, at night water
flows in the opposite direction.
According to
the figure, in the daytime water
from the river at a high-level reservoir passes through the opened dam and flows along the way to the power
station. Then
the generator is operated by the reversible turbines to transform the waterpower into electric power
and send it to power
lines. lastly
, the electricity is sent to the national grid.
On the other hand
, at nighttime, water
from the lower-level reservoir is pumped to a higher level by the reversible turbines. The dam is closed to collect the water
until the next day and uses accumulated water
as a raw material in the daytime process again.Submitted by jeanbabyfrog on
