The flow diagram illustrates the production of electricity in a hydroelectric power station with water.
Overall, electricity is generated in two steps : fistly , flow of water to generate electricity (day), and secondly, flow of water during pumping (night)
In the beginning, the fist process : Flow of water to generate electricity is realized.
The water from river is stored in a high-level reservoir . Once the Dam is opened the day , the water flows to generator who due to turbines generates electricity . Next , electricity is carried off through power lines to National grid.
Furthermore, after this process, the water is magazined in a low – level reservoir until the night . The second process starts with : Flow of water during pumping. Then, the water is pumped by reversible turbines to the river , afterwards into high- level reservoir.
