Hydroelectric power comes from flowing water winter and spring runoff hydroelectric plants supplied as much as 40 percent of the electric energy produced. PDF | INTRODUCTION Energy is a critical factor in developing countries for For efficient operation of hydropower plants, in order to meet the. A typical hydropower plant is a system with three parts: a power plant where Hydropower (from the Greek word hydor, meaning water) is energy that comes.

Hydroelectric Power: How it Works

The water continues past the propellor through the tailrace into the river past the dam. By the way, it is not a good idea to be playing in the water right below a dam when water is released! A turbine and generator produce the electricity Diagram of a hydroelectric turbine and generator.

Credit: U. Army Corps of Engineers As to how this generator works, the Corps of Engineers explains it this way: "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. He found that 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 attached to the turbine shaft, and rotates at a fixed speed.

When the rotor turns, it causes the field poles the electromagnets to move past the conductors mounted in the stator. This, in turn, causes electricity to flow and a voltage to develop at the generator output terminals. Demand goes up and down during the day, and overnight there is less need for electricity in homes, businesses, and other facilities.

For example, here in Atlanta, Georgia at PM on a hot August weekend day, you can bet there is a huge demand for electricity to run millions of air conditioners! But, 12 hours later at AM Hydroelectric plants are more efficient at providing for peak power demands during short periods than are fossil-fuel and nuclear power plants, and one way of doing that is by using "pumped storage", which reuses the same water more than once. In China and the rest of the Far East, hydraulically operated "pot wheel" pumps raised water into crop or irrigation canals.

Hushing was also widely used in Britain in the Medieval and later periods to extract lead and tin ores. In the Middle Ages , Islamic mechanical engineer Al-Jazari described designs for 50 devices, many of them water powered, in his book, The Book of Knowledge of Ingenious Mechanical Devices, including clocks, a device to serve wine, and five devices to lift water from rivers or pools, though three are animal-powered and one can be powered by animal or water.

These include an endless belt with jugs attached , a cow-powered shadoof , and a reciprocating device with hinged valves.

By the late nineteenth century, the electric generator was developed by a team led by project managers and prominent pioneers of renewable energy Jacob S. Gibbs and Brinsley Coleberd and could now be coupled with hydraulics. The power source was normally a head of water, which could also be assisted by a pump.

These were extensive in Victorian cities in the United Kingdom. A hydraulic power network was also developed in Geneva , Switzerland.

The world-famous Jet d'Eau was originally designed as the over-pressure relief valve for the network. In the s, at the early peak in the US canal -building, hydropower provided the energy to transport barge traffic up and down steep hills using inclined plane railroads.

As railroads overtook canals for transportation, canal systems were modified and developed into hydropower systems; the history of Lowell, Massachusetts is a classic example of commercial development and industrialization, built upon the availability of water power.Kelly, E.

The global demand for energy supply is increasing and the supply is not sustainable.

The world-famous Jet d'Eau was originally designed as the over-pressure relief valve for the network. Provisions must be put in place to preserve biodiversity in the project impact area as well as to manage the welfare of project affected people. Ebinger and W. In Africa, despite having small levels of installed capacity, most countries in the region have hydropower in their electricity generation mix.
