The diagram shows the process of a hydroelectric power station to produce electricity. Overall, it is a linear process consisting of three main stages : collecting, generating, and finishing.
The first step is what we call, the collecting stage. At this point, dam will gather water from the river and it is saved inside a high-level reservoir at night. During the day, collected water will be continued and proceeded to the generator machine. To the next stage is generating, functioning inside the power station. It is helped by a fundamentally reversible turbines to operates during the day, whereas at night, the high-level reservoir will stored back the water because the turbines processed to pump it.
Meanwhile, finishing occurs after the machinery fragments’ completed their job. Finally, formed electricity continues to the provided power lines where it is then proceeded for the national grid. However, the processes are repeated for the main energy sources. During the day, water that is used will continue to the low level reservoir whereas during the day, the direction is reversed back into the high level reservoir.
