Hydroelectric Power Plant Flow Diagram. 1 the dam sometimes only weir 2 the intake or headworks 3 the pressure tunnel 4 the surge tank 5 the penstock 6 the power house 7 the tailrace. Hydro plants are the most widely used 18 20 percent global electricity consumption form of renewable sources of energy according to a survey.
Layout and working of hydroelectric power plant the above image shows the typical layout of a hydroelectric power plant and its basic components. These three most essential elements are coal air and water. At night the water flows back in the other direction towards an initial reservoir and the river.
This reservoir creates sufficient water head.
Overall the production of hydroelectricity is cyclical and consists of four main parts. First of all the dam stores river water behind it in the upper reservoir that has. The amount of power and therefore energy that you can generate is proportional to the head and the flow. Hydroelectric power station needs huge amount of water at sufficient head all the time.
