ABSTRACT

Power Consumption has gone at such a high extent that every country is looking for the alternative resources for generation of electricity. Power Generation is becoming the utmost priority of every developing nation. As it is directly serving their Industry and Indirectly their growth in the world. So the countries are searching different alternatives to generate as much power and electricity as possible .As the Science is progressing it is giving a lot of benefits to the mankind, so the people are thinking different ways for generating power and electricity Science has produced such devices which have revolutionized the whole tradition of living. Hydroelectric power is electricity generated by hydropower. Hydropower is harnessed through the gravitational force of falling or flowing water. On a worldwide standpoint, it is the most widely used form of renewable energy, supplying 2998 TWh of hydroelectricity in 2006 and even more today. Hydropower has been used for centuries by humans. The electricity is typically created when the water is passed over large mechanical turbines, the water pressure forces the turbines to turn, the mechanical energy created is then converted into electricity. In this report emphasis of our research is to study hydroelectricity how it is produced and its advantages and disadvantages

Introduction

* Hydroelectric power is electricity generated by hydropower. Hydropower is harnessed through the gravitational force of falling or flowing water. On a worldwide standpoint, it is the most widely used form of renewable energy, supplying 2998 Tw of hydroelectricity in 2006 and even more today. Hydropower has been used for centuries by humans. The electricity is typically created when the water is passed over large mechanical turbines, the water pressure forces the turbines to turn, the mechanical energy created is then converted into electricity Literature

Hydro comes from the Greek word for water. Hydro-electricity, or hydro-power, is usually generated by turbines in a dam in a river. The dam means that a great body of water builds up in the river valley behind the dam. This is released through the turbines when electricity is needed. 

Smaller than dams are barrages across the mouths of rivers which capture water from high tides and release it to generate electricity. Smaller still are turbines in river and tidal streams which do the same thing. [2] THEORY

Power is Computed
* Before a hydroelectric power site is developed, engineers compute how much power can be produced when the facility is complete. The actual output of energy at a dam is determined by the volume of water released (discharge) and the vertical distance the water falls (head). So, a given amount of water falling a given distance will produce a certain amount of energy. The head and the discharge at the power site and the desired rotational speed of the generator determine the type of turbine to be used. * The head produces a pressure (water pressure), and the greater the head, the greater the pressure to drive turbines. This pressure is measured in pounds of force (pounds per square inch). More head or faster flowing water means more power. * To find the theoretical horsepower...
