The diagram illustrates how a hydroelectric power station operates to generate electricity. Overall, the process is cyclical and involves sophisticated equipment and infrastructure.
Initially, water from a river is directed into a high-level reservoir, which is maintained by a dam. Below the dam, there is a valve that regulates water flow into the low-level reservoir via reversible turbines. These turbines play a dual role, producing energy during the day and facilitating the return of water to the high-level reservoir at night. During the daytime, water is released from the high-level reservoir, after which it flows through the turbines, and generates electricity. At night, the water collected in the low-level reservoir is pumped back up, ensuring a continuous supply.
The generated electricity is then transferred to the national grid through power lines connected to the generator. The entire process, thus, is efficient, utilizing both water movement and advanced turbines to maintain a steady supply of electricity
