3INTRODUCTION HYDRO POWER email@example.com 1) One of the most widely used renewable source of energy for generating electricity on large scale basis is hydropower2) The power obtained from river or ocean water is called as hydropower3) Hydropower is the renewable source of energy since water is available in large quantities from rain, rivers, and oceans and this is will be available for unlimited time to come
4HISTORY firstname.lastname@example.org - In the 1700's, hydropower was broadly used for milling of lumber and grain and for pumping irrigation water- Appleton, Wisconsin became the first operational hydroelectric generating station in the United States, in 1882, producing 12.5 kilowatts (kW) of power- The total electrical capacity generated was equivalent to 250 lights- Still in use today, Niagra Falls was the first hydropower site developed for a vast quantity of electricity- The largest and last masonry dam built by the U.S. Bureau of Reclamation was the Roosevelt Dam in Arizona between ; its power output has increased from 4,500 kW to 36,000 kW

6Based on the Nature of Load Based on the Head of Water Available1) Low head hydroelectric power plants2)Medium head hydroelectric power plants3) High head hydroelectric power plantsBased on the Nature of Load1) Base load hydroelectric power plants2) Peak load hydroelectric power plants
7CHAPTER 2 PRINCIPLE OF HYDRO POWER PLANT WATER CYCLE The continuous cycle in which water changes from watervapor in the atmosphere to liquid water through condensationand precipitation and then back to water vapor throughevaporation, transpiration, and respirationVAPORATION PRECIPITION RAINWater energies: Kinetic energy , Potential energyPROCESS / STAGES1) Water in reservoir2) Fall in turbine blade3) Shaft rotation4) Electric generation5) Flow back of waterWater cycle in the hydraulic power plant

12DAM firstname.lastname@example.org 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.
13TYPES F DAMS ON THE HEAD LEVEL Low head hydroelectric power plants (>30 m)Medium head hydroelectric power plants ( 30 m to 300 m)High head hydroelectric power plants (more than 300 m , up to 1000m )

firstname.lastname@example.org 7) Transformer 8) Tailrace Two coils: the supply coil and the outlet coil.7) TransformerConverts the alternating current to high voltage current.Voltage required for various applications is 110V or 230V.Numbers of turns in outlet coil are double of supply coil, the voltage produced is also double.8) TailracePipeline to drain the waterThe potential energy of water in the tailrace has been used to generate electricity
16INTAKEA 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.
17PENSTOCK conveying water from the intake to the power house. Of concrete in low headsOf steel iis suitable for all heads
18TRASH RACK cleaning machine, which removes debris from water In order to save water ways and electromechanical equipment from any damage.Set steel bars on edge to the flow of water and space about 1“ apartA head gate or valve should be installed below the trash rack to control flow and to allow the turbine to be inspected and repaired.
20CASE STUDY OF “HIRAKUND DAM” Built across the Mahanadi riverabout 15 km from Sambalpur in the state of Orissa in India.Built in 1956Length is about (26 km)It was the first major multipurpose river valley project started after India's independence.SALIENT FEATURES(A) HYDROLOGICAL :-(a) Catchment Sq. Kms (32200 sq miles)(b) Rain fall(mm) - Original RevisedHISTORYTop dam level R.L M. (R.L.642 ft.)Dead storage level R.L M (R.L 590 Ft)N: Installed Capicity = MW

25ADVANTAGES & DISADVANTAGES OF HYDRO POWER PLANTAdvantages1) No fuel required2) Cost of electricity is constant3) No air-pollution is created4) Long life5) Cost of generation of electricity6) Can easily work during high peak daily loads7) Irrigation of farms8) Water sports and gardens9) Prevents floods
26DISADVANTAGES email@example.com 1) Disrupts the aquatic ecosystems2) Disruption in the surrounding areas3) Requires large areas4) Large scale human displacement5) Very high capital cost or investment6) High quality construction7) Site specific8) Effects on environment9) Safety of the dams
