The diagram depicts the process of electricity production in a hydroelectric station. Overall, the procedure contains four rather simple stages.
It commences, when river water from higher-level reservoir flows down through intake, which is open at midday. Following this, water reaches the chamber the chamber with reversible turbine, which is directly connected to generator, and then is made to spin. Once the turbine has begun propelling, generator then starts producing
energy. Next, generated electricity is send through power lines for multipurpose usage.
Having left the turbine chamber, water then flows into low-level reservoir. The next step is that, turbine starts rotating in opposite direction and the reverse process begins. Finally, at night, water is pumped up back from low-level to higher-level
reservoir and this cyclic procedure happens constantly.
