- 3. Hydroelectric power (often called hydropower) is considered a renewable energy source. A renewable energy source is one that is not depleted (used up) in the production of energy. Through hydropower, the energy in falling water is converted into electricity without "using up" the water. Hydroelectric power (hydropower) systems convert the kinetic energy in flowing water into electric energy. INTRODUCTION
- 4. TYPES OF HYDRO POWER PLANT As per height of water or water head, the hydroelectric power plant can be divided into three categories: a.Low Head b.Medium Head c.High Head
- 5. INTRODUCTION ABOUT UPPER SINDG HYDRO ELECTRIC PROJECT Upper Sindh II Hydroelectric Project is located in the Sindh Nallah & Wangath Nallah rivers of Jhelum in the state of Jammu & Kashmir. The power project has a total installed capacity of 105 MW, So the type of project is Major. The river, where the water is sourced for the project is Sindh Nallah & Wangath Nallah Rivers of Jhelum. Indus River is the basin of the project. The power project is erected in the North HE region of the country and the power project is completed in 2002. The power station is owned by Jammu and Kashmir Government and the operating company is Jammu and Kashmir Power Development Corporation. The beneficiary union territory of the plant is Jammu & Kashmir. The structure type of power house is Weir and the name of the Weir is Upper Sindh - II Weir. The power house built for the purpose is Upper Sindh II Power House, which is now Operational and the type of PH is Surface. The completion of the power project is happened in 2002. The type of Turbine built in the power house is Francis. The maker of both Turbine and Generator of the power house is by the BHEL, India. There are three units in operation and all the units have a capacity of 35 MW each.

- 7. SELECTION OF SITE In site site selection of hydroelectric plant following point we should keep in mind: 1. Water Availability. 2. Storage of Water. 3. Site Selection for Hydroelectric Power Plant According to the Availability of Water Head. 4.Distance from the Load Center. 5. Accessibility of the Site. 6. Pollution of Water Resource. 7. Sedimentation. 8. Large Catchment Area. 9. Site Selection for Hydroelectric Power Plant According to the Availability of Land.
- 8. ESSENTIAL ELEMENTS OF HYDRO POWER PLANT 1.Forebay 2.Intake structure 3.Penstocks 4.Surge tank 5.Turbines 6.Draft tube 7.Tail race 8.Power House
- 9. FOREBAY Enlarged body of water provided in front of penstock Provided in case of runoff river plant and storage plant. The Main function is to store water that is rejected by plant. Power house located closed to dam penstock directly take water from a reservoir, reservoir act as forebay. INTAKE STRUCTURE Water conveyed from forebay to penstocks through intake structures. Main components are the trash rack and gate. Trash rack prevent entry of debris.
- 10. PENSTOCKS open or closed conduits which carry water to the turbines. made of reinforced concrete or steel. Concrete penstocks are suitable for low heads less than 30mtrs. steel penstocks are designed for any head. thickness of penstocks increases with head or water pressure penstocks gates are fixed to initial of penstocks, and flow of water is controlled by operating penstock gates. Either buried in ground or kept exposed. SURGE TANK Additional storage for near to turbine usually provided in high head plants. located near the beginning of the penstock. As the load on the turbine decreases or during load rejection by the turbine, the surge tank provides space for holding water. surge tank over comes the abnormal pressure in the conduit when load on the turbine falls and acts as a reservoir during increase of load on the Surge Tank.
- 11. TURBINES turbines are used to convert the energy water of falling water into mechanical energy. water turbine is a rotary engine that takes energy from moving water. flowing water is directed on to the blades of a turbine runner, creating a force on the blade. Since the runner is spinning, the force acts through a distance n this way, energy is transferred from the water flow to the turbine. The principal types of turbines are: Impulse turbine,Reaction Turbine and francis turbine. TURBINE USED IN UPPER SINDH HYDRO POWER PROJECT FRANCIS TURBINE The Francis turbine is a reaction turbine, which means that the working fluid changes pressure as it moves through the turbine, giving up its energy. The turbine is located between the high- pressure water source and the low-pressure water exit, usually at the base of a dam. Francis turbines are the most common water turbine in use today and can achieve over 95% efficiency. HEAD : 45- 400 METER FLOW RATE :10-700 m^3/s
- 12. DRAFT TUBE is a pipe or passage of gradually increasing cross sectional area, which connect to the exit to tail race. it reduces high velocity of water discharged by the turbine. draft tube permits turbines to be installed at a higher level than the tail race level, which help the maintenance and repair of turbines. TAIL RACE Tail race tunnel or channel are provided to direct the used water coming out of draft tube back to the river. important criteria of designing the tail raceis kind of draft tube, the gross head and geographical situation of the area. Tail race is designed in such a way that water hammer is minimized when water leaves the draft tube. POWER HOUSE Power house contains the electro-mechanical equipment i.e. hydropower turbine, Generator, excitation system, main inlet valves, transformers, Switchyard, DC systems, governor, bus duct, step-up transformers, step down transformers, high voltages switch gears, control metering for protection of systems.
- 13. WORKING Initially the water of the river is in Catchments Area. From catchments area the water flows to the dam. At the dam the water gets accumulated. Thus the potential energy of the water increases due to the height of the dam. When the gates of the dam are opened then the water moves with high Kinetic Energy into the penstock. Through the penstock water goes to the turbine house. Since the penstock makes water to flow from high altitude to low altitude, Thus the Kinetic Energy of the water is again raised.
- 14. ADVANTAGES No fuel charges. Less supervising staff is required. Maintenance & operation charges are very low. Running cost of the plant is low. The plant efficiency does not changes with age. It takes few minutes to run & synchronize the plant. No fuel transportation is required. No ash & flue gas problem & does not pollute the atmosphere. These plants are used for flood control & irrigation purpose. Long life in comparison with the Thermal & Nuclear Power Plant.
- 15. DISADVANTAGES The initial cost of the power plant is very high. Takea s long time for construction of the dam. Generally, Such plants are located in hilly areas far away from the load center & thus they require long transmission lines & losses in them will be more. Power generation by hydropower plant is only dependent on the natural phenomenon of rain. Therefore at the time of drought or summer session, the Hydro Power Plant will not work.
