The diagram below shows how electricity is generated in a hydroelectric power station. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram illustrates how electric
power
is produced in an electric station, powered by water
.
Overall
, it can be seen that this
is a cyclic man-made process, which contains water
storage at a high level, water
flowing downwards, necessary for electric power
production, low-level storage and pumping water
back up for reuse.
Firstly
, the water
is poured from a river into a high-level reservoir, limited by a dam with an intake at the bottom. During the day, the water
passes through it and goes downhill, reaching the reversible turbines, helping them to operate a generator in the power
station. Thus
electricity is generated and spread among Power
lines and then
reaches the National grid.
The rest of the water
is collected in low-level containers and during the night is pumped out through the turbines uphill, reaching the high-level tank once again. It is then
ready to be involved in the process again.Submitted by delulcheva on
