  1. contents • INTRODUCTION. • HYDRO POWER PLANT IN INDIA. • WORKING. • ELEMENTS OF HYDRO-ELECTRIC POWER PLANT. • CLASSIFICATION. • TYPES OF TURBINES. • ADVANTAGES & DISADVANTAGES. • CONCLUSION

  2. introduction • Hydroelectricity is the term referring to electricity generated by hydropower. • The production of electrical power through the use of the gravitational force of falling or flowing water.

  3. HYDRO POWER PLANT IN INDIA • First Hydro Power Plant was constructed at Mysore in 1902 named as “ SHIVANASAMUDRA ” having capacity 4.5 MW. • Second Hydro Power Plant was constructed at Maharashtra in 1914 named as “ KHOPOLO ” having capacity 50 MW. •  The present installed capacity is  37,367 MW; 21.53% of total Electricity Generation in India.

  4. WORKING

  5. TURBINE & GENERATOR COMBINATION

  6. Elements of hydro-electric power plant • Storage Reservoir • Spillway • Surge tank • Penstock • Tail Race

  7. CLASSIFICATION Hydro-Electric power plants are classified according to: • Availability of water head. • Low Head. • Medium Head. • High Head • Type of load they supply. • Base Load. • Peak Load.

  8. Types of turbine Mainly water turbines are of three types: • Pelton Wheel • Specific Speed – 10-50 rpm. • Head above 200 m. • Francis Turbine • Specific Speed – 60-300 rpm. • Head 30 m – 200 m. • Kaplan Turbine • Specific Speed – 300 – 1000 rpm. • Head less than 30 m.

  9. THE THREE GORGES DAM, CHINA (22,500 MW)

  10. ADVANTAGES • No fuel charges. • Maintenance & operation charges are very low. • Running cost of the plant is low. • The plant efficiency does not changes with age. • Takes few minutes to run & synchronize the plant. • No fuel transportation is required. • No Pollution. • Used for flood control & irrigation purpose. • Long life.

  11. disadvantages • Requires large area. • Initial cost is high. • Takes long time for construction of Dam. • Requires long transmission lines. • Power generation mainly depends on rain.

  12. conclusion • Hydroelectric power was one of the first renewable sources of energy, and therefore the most developed currently. • Overtime other renewable sources of energy will develop and become competitive, offering a wider variety of affordable renewable energy. • Hydroelectric’s market growth in the United States seems to have reached a plateau and is unlikely to see significant growth in the future.
