HYDRO ELECTRIC POWER PLANT: 

HYDRO ELECTRIC POWER PLANT

WHAT IS HYDRO POWER? The objective of a hydropower scheme is to convert the potential energy of a mass of water, flowing in a stream with a certain fall to the turbine (termed the "head"), into electric energy at the lower end of the scheme, where the powerhouse is located. The power output from the scheme is proportional to the flow and to the head. :

ELEMENTS OF HYDRO POWER

Slide 9: 

FIRST ELEMENT :- DAMS

The movement of water can be used to make electricity. Energy from water is created by the force of water moving from a higher elevation to a lower elevation through a large pipe (penstock). When the water reaches the end of the pipe, it hits and spins a water wheel or turbine. The turbine rotates the connected shaft, which then turns the generator, making electricity. :

A dam failure can have sever effects downstream of the dam. During the lifetime of a dam different flow conditions will be experienced and a dam must be able to safely accommodate high floods that can exceed normal flow conditions in the river. For this reason, carefully passages are corporated in the dams as part of structure. These passages are known as spillways.:

2nd ELEMENT:- INTAKE: 

2 nd ELEMENT:- INTAKE

A water intake must be able to divert the required amount of water in to a power canal or into a penstock without producing a negative impact on the local environment. :

3rd ELEMENT:- PENSTOCK

PENSTOCK “conveying water from the intake to the power house”. The water in the reservoir is considered stored energy When the gate opens the water flowing through the penstock becomes kinetic energy because it is in motion. :

4 th ELEMENT TURBINES

Slide 17: 

The water strikes and turns the large blades of a turbine, which is attached to a generator above it by way of a shaft. The most common type of turbine for hydropower plants is the Francis Turbine, which looks like a big disc with curved blades.

After passing through the turbine the water returns to the river trough a short canal called a tailrace. :

5TH ELEMENT GENERATOR

As the turbine blades turn, so do a series of magnets inside the generator. Giant magnets rotate past copper coils, producing alternating current (AC) by moving electrons. :

Inside the Generator:- The heart of the hydroelectric power plant is the generator. The basic process of generating electricity in this manner is to rotate a series of magnets inside coils of wire. This process moves electrons, which produces electrical current. :

As the turbine turns, the excitor sends an electrical current to the rotor. The rotor is a series of large electromagnets that spins inside a tightly-wound coil of copper wire, called the stator. The magnetic field between the coil and the magnets creates an electric current. :

6TH ELEMENT:- TRANSFORMERS: 

6 TH ELEMENT:- TRANSFORMERS

A transformer is a device that transfers electrical energy from one circuit to another through a shared magnetic field. A changing current IP in the first circuit (the primary) creates a changing magnetic field; in turn, this magnetic field induces a voltage VS in the second circuit (the secondary). The secondary circuit mimics the primary circuit, but it need not carry the same current and voltage as the primary circuit. Instead, an ideal transformer keeps the product of the current and the voltage the same in the primary and secondary circuits.:

TRASH RACK Almost all small hydroelectric plants have a trash rack cleaning machine, which removes material from water in order to avoid entering plant water ways and damaging electromechanical equipment.:

A SIMPLE OVER VIEW:-

Slide 31: 

Flowing water creates energy that can be captured and turned into electricity. This is called hydropower. Hydropower is currently the largest source of renewable power, generating nearly 10% of the electricity used in the United States. The most common type of hydropower plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which, in turn, activates a generator to produce electricity. But hydropower doesn't necessarily require a large dam. Some hydropower plants just use a small canal to channel the river water through a turbine.
