The image displays a labeled diagram of the structure and operation of a hydroelectric power station, including a dam with a high-level reservoir feeding into reversible turbines that operate as a generator during the day and pump water into the high-level reservoir at night; the turbine connects to a power station that produces electricity for the national grid, and there is also a low-level reservoir beneath the power station; a specific part is labeled as intake (Day: open, Night: closed). There are no numerical data points or percentages.

Given the complexity of the image, the above description may not be entirely accurate.

The diagram display the manufacturing process of electricity in a hydroelectic power station.

Overall, there are four stage to complitition the process ,and the main step are storing water ,managing flow and the operation of turbines and generator.

Firstly,the water is pickup through the river and stored in a high level reservoir behind a dam. During the day time, dam is opened and allow the reserved water to flow towards the Reversible turbines.

Simultaneously, the speed of water flow rotated a turbine and operate a generator to produce electricity from the water flow. The generated electricity is then transmitted to the national grid via power lines.After passing through the reversible turbine ,the water flow pumed and stored into the low level reservior. These all process is done on day time.But at the night hours, the reversible turbine acting as a pump for low level reservior and transported water back into the high level reservior for recreating this process.
