The diagram demonstrates the process of electricity production in a hydroelectric power station.
Overall, the given hydropower system is broadly distributed into day and night alternating stages. The process begins with water flows from the river into a high-level reservoir and ends with the transmission of electricity to the national grid.
A dam is a large barrier constructed to raise the level of water in the high-level reservoir and channel its flow. In the day time, the moving water goes through the diurnal-opened intake to generate energy. The flow of water spins the turbine. This turbine is connected to a generator which produces electricity when the turbine drives. The generated electricity is then sent to a national grid through power lines while the excess water is stored in a low-level reservoir.
At night, the station operates in a reversible method. The turbine pumps water in a low-level reservoir into a higher one which is closed during the night. The river water is stored at the upper level and later it flows down, starting the cycle again.
