The function of a hydro power plant energy is to use the potential energy of stored water and turn it first into mechanical energy and then electricity.
In this hydro power energy scheme, a collection system causes a drop of water that creates a certain potential energy accumulated. The passage of water through the turbine develops in it a rotary motion that drives the alternator and produces electric current.
The advantages of hydro power Energy Plants are evident:
1. Require no fuel, but they use a renewable form of energy, constantly replenished by nature for free.
2. It is clean, it does not pollute the air and not water.
3. You can often combined with other benefits such as irrigation, flood protection, water supply, roads, navigation, and decoration of the ground and even tourism.
4. The costs of maintenance and operation are low.
5. Engineering necessary to build a hydro power energy plant have considerable length.
6. The hydraulic turbine is a machine simple, efficient and secure, which can be started and stopped quickly and requires little monitoring is its maintenance costs, generally small.
