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 function process of one particular hydroelectric power station.
The whole procedure of generating energy can be divided into two stages. During the daytime the river flows into a high-level pool, going through the intake of a dam and
then
downhill in order to generate electricity. After reaching the power station, river water
is used to activate the reversible turbines which operate the generator to generate power, transported to the National grid via powerlines. Finishing the whole process, water
will flow to a low-level storage, where it will be preserved.
At night the system works completely reversely. Water
from the pool at the high altitude will be pumped into the storage at the low altitude using reversible turbines. After that, the intake of the dam will be closed so that water
can be stored at a higher altitude, which is used to complete to procedure during the day. Hence
the cycle is formed.
According to
the chart, it is obvious how the electricity is generated using the system.Submitted by 1762832590 on
