The diagram shows how electricity is generated in a hydroelectric power station. lbww
The flow chart shows the process of electricity being generated in a hydroelectric power station, and the ways to produce electricity from water are complex. At the first stage, the river is led to a high-level reservoir blocked by a dam. Under the dam, there is an intake, which uses the flow of water to produce electricity in the daytime and pump at night. After that, the water flows into the power station through a tube, and passes through reversible turbines. In the morning, water pushes ahead the turbines in order to operate generators. After this step, the generator helps to deliver electricity through the power lines to the National grid. Hence, in the evening, water which is stored in the low-level reservoir is pumped in the opposite direction and goes back into the high-level reservoir. Finally, the water will do this process again and again. In all, electricity production from water is rotating and recycled.
