5. ELEMENTS OF HYDRO POWER

6. FIRST ELEMENT :- DAMS

7. 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.

8. 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. What are Spill ways?

11. 2 nd ELEMENT:- INTAKE

12. 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. INTAKE:-

13. 3rd ELEMENT:- PENSTOCK Engr. UMAIR ALTAF 3nd ELEMENT:- penstock

14. PENSTOCK  conveying water from the intake to the power house.  concrete in low heads  steel is suitable for all heads

15. Penstock has:  Surge Tank  reducing water hammering in pipes which can cause damage to pipes.  thereby regulating water flow and pressure inside the penstock.

16. TRASH RACK  cleaning machine, which removes debris from water In order to save water ways and electromechanical equipment from any damage.  A head gate or valve should be installed below the trash rack to control flow and to allow the turbine to be inspected and repaired.

17. TRASH RACK

18. 4 th ELEMENT TURBINES

19.  its is to convert the K.E of moving water into mechanical energy  The water strikes and turns the large blades of a turbine, turbine is attached to a generator with shaft.

21. WICKETS GATE  key component in hydroelectric turbines that control the flow of turbines that control the flow of water from the Penstock to the turbine blades Penstock

22. 5TH ELEMENT GENERATOR

23. BASIC PRINCIPAL  Heart of the hydroelectric power plant.  The basic process is to rotate a series of gaint magnets inside coils of wire. This process moves electrons, which produces electrical current.

24. INSIDE THE GENERATOR:- 1. Shaft 2. Excitor 3. Rotor 4. Stator 1. Shaft 2. Excitor 3. Rotor 4. Stator Engr. UMAIR ALTAF

25. 6 TH ELEMENT:- TRANSFORMERS Engr. UMAIR ALTAF

26. transformer Its function is to step up the voltage and pass it out to the electrical grid or power house Its function is to step up the voltage and pass it out to the electrical grid or power house

27. 7 TH ELEMENT OUTFLOW / TAILRACE:-  After passing through the turbine the water returns to the river trough a short channel called tailrace.
