Hydro Power Plant

There are several ways to produce electricity . The Most Common and cheap way to produce electricity is from water (Hydro Power Plant). hydroelectric and coal-fired power plants produce electricity in a similar way.

In Hydro Power Plant water is a power source use to turn a propeller (Commonly known as Shaft) called a turbine. Which then turns a metal shaft in an electric generator, which is the motor that produces electricity.

The theory is to build a dam on a large river that has a large drop in elevation. The dam stores lots of water behind in the reservoir. Near the bottom of the dam wall there is the water intake. Moreover, Gravity causes it to fall through the penstock inside the dam.

Thus, At the end of the penstock there is a turbine propeller, through which it turns by the moving water. The shaft from the turbine goes up into the generator, which produces the power.

While, Power lines are connect to the generator that carry electricity to your home. The water continues past the propeller through the tail-race into the river past the dam.

“A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity. The operation of a generator is based on the principles discovered by Faraday.

According to Faraday’s Law “when a magnet is moved past a conductor, it causes electricity to flow”.

In a large generator, electromagnets are made by circulating direct current through loops of wire wound around stacks of magnetic steel laminations.

These are called field poles, and are mounted on the perimeter of the rotor. The rotor is attach to the turbine shaft, and rotates at a fixed speed. When the rotor turns, it causes the field poles (the electromagnets) cuts and the current produced in the stator.

This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals.” Then the electricity transmit the consumers.
