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 shows a hydroelectric
power
station and the way electricity is generated. In general, water comes to the generator from the river in the day and after some levels, it turns turbines so that generator in there produces the service.
As can be seen from the diagram, the water from the river, which is stored behind the dam in the High-level reservoir, is the main character of this
process. Firstly
, it enters the flow through the intake under the dam in the day, after it passes it reaches the power
station where electricity is generated, there are reversible turbines that the liquid turns them and they operate the generator, and after that, water goes to the low-level reservoir. After processes in the power
station, the electricity is leaded
to the national grid through the Correct your spelling
led
power
lines. At night the process is reversed, and the reversible turbines are used to pump the liquid back into the high-level reservoir, and at the end
, the intake behind the dam is closed until it is opened the next day.Submitted by Farzaneh Ka on
