The diagram illustrates the operation of a hydroelectric power station, demonstrating how electricity is generated through the flow of water.
Overall, there are two primary stages: how electricity is produced during the day with water flowing downwards, and how it is pumped back up at night.
In detail, water stored in a high-level reservoir behind a dam, sourced from a river, is released through an intake opening during the day. Once the water is released, it flows downwards through turbines, which direct it to a generator. The movement of water then forces blades located at the bottom of the generator to rotate, converting kinetic energy into electricity. After this, the energy is distributed to the national grid through power lines, supplying people with sustainable power.
At night, the turbines are reversed, drawing stored water from the low-level reservoir back up to the high-level reservoir. When the pumped water enters the high-level reservoir, the intake is closed to prevent water from flowing, allowing the process to begin again the next day. This setup is not only efficient but also provides a consistent power supply to residents.
