The provided diagram illustrates the process by which power is produced in a hydroelectric power station.
Overall, it is evident from the diagram that the process by which electricity is generated in a hydroelectric power station is a multistep man-made process, which consists of 5 major stages.
In the first stage, sufficient water is transferred to an artificial reservoir, which is called high-level reservoir, which is obstructed by a dam. Afterwards, the dam is opened at only day time, allowing the water to flow toward power station with high current. Following this, high flow of water enables turbines, located on the beginning point of the power station, which run generator during day time. As generator runs, it starts producing electricity, which is then transmitted to the power lines, thereby supplying power to national grid.
In addition to this, water passing through the turbines are then moved to a low-level reservoir. Furthermore to this, the turbines act as pump during night time, thus pumping water to high-level reservoir from low-level. Then the process continues again.
