Our system will evaluate the answer based on this AI-generated description.
The image depicts a diagram of a hydroelectric power station with labeled components, including a high-level reservoir, dam, intake (open during the day, closed at night), reversible turbines (operating the generator during the day, pumping water at night), power station with a generator, power lines connecting to the national grid, and a low-level reservoir. The arrows indicate the flow of water during the day and the flow of water or electricity during the night.
Given the complexity of the image, the above description may not be entirely accurate.

The picture illustrates generating process of electricity in hydroelectric station of power.
The components of electricity generating process include low-level reservoir, dam, intake, generator, power station, power lines connected to national grid, reversible turbines and low-level reservoir.
First, the water of river collected in high-level reservoir and secured by dam. Then water flow into electricity generator in daytime and water stocked in low-level reservoir. Power lines that pinned to national grid helps generating process.
At nightime, reversible turbines pump generated water in low-level reservoir to the high-level reservoir again. Power lines collect energy and electricity from water and send it to the national grid
