The illustration demonstrates the generation of electricity in a hydropower electric station.
The procedure is generally divided into two parts based on the activity of the plant during the day and night. Overall, the primary step of energy generation occurs only in the daytime, while the other takes place at night.
In the first step, water from the river is collected in a high-level reservoir. Following this, during the daytime, the dam is opened, resulting in the downward flow of water towards the reversible turbines. These turbines operate the generator, which produces electricity. The generator is connected to a national grid through a series of power lines. The water is then collected in a low-level reservoir.
At night, the collected water is pumped back to a higher level from the lower-level reservoir by the mechanism of the reversible turbines. Furthermore, once the water reaches the dam, the dam is closed. During the daytime, the same procedure commences again.
