It was quite an interesting topic to work on Hydro Electricity Production and to investigate. We were guided by the Assistant Engineer DVC Panchet. We are really thankful to you and your coordinates for guiding and providing us with important data and pictures. Last but not the least I want to thank the almighty and my parents who provided me with enough courage and support. I also want to thank my fellow friends who also proved to be a helping hand upon completion of this project.
  4. 4. PAGE 2 OBJECTIVE Upon working on this Company like DVC it was quite impressive and helpful for me, which not only helped me to boost my practical knowledge but also helped me to face on how to work in an Industry and operate the machines. I also found out while working in DVC that the machines that were being used was Class A type machines, and it was indeed a First Class Industry. My training in DVC Panchet helped me in acquiring a vast knowledge on how to work in a Power Station.
  5. 5. PAGE 3 ABSTRACT:- As a result of the catastrophic flood of 1943, the Governor of Bengal appointed the Damodar Flood enquiry committee to suggest remedial measures. It suggested creating an authority similar to that of the Tennessee Valley Authority in the United States. W.L.Voorduin, senior engineer of TVA prepared a preliminary report that outlined a plan designed to achieve flood control, irrigation, power generation and navigation. As a result, Damodar Valley Corporation came into existence in 1948 for development and management of the basin as a whole. While Voorduin envisaged the construction of eight dams and a barrage, it was later decided to have only four dams at Tilaiya, Konar, Maithon and Panchet, and Durgapur Barrage. The first dam was built across the Barakar River at Tilaiya and inaugurated in 1953. Two years later, in 1955, the second dam across the Konar Riverwas inaugurated. The third dam across the Barakar at Maithon was inaugurated in
  6. 6. PAGE 4 1957, and the fourth dam across the Damodar at Panchet was inaugurated in 1959. The Damodar forms the border between Dhanbad district of Jharkhand and Purulia district of West Bengal, before meeting the Barakar at Dishergarh and flowing fully through West Bengal. Panchet Dam has been constructed a little above its confluence with the Barakar. While Dhanbad district is on the northern bank of Panchet reservoir, Purulia district is on the southern bank. Panchet Hill rises above Panchet Dam. The Panchet Dam is an earthen dam with concrete spillway. The reservoir taps a catchment area of 10,961 square kilometers (4,232 sq. mi). The average annual basin precipitation is 114 centimeters (45 in) and average annual run off is 4540 million m3 . At the dam site the maximum observed flood (June 1949) was 8558 m³/s. For the project the spillway design flood that was adopted was 17853 m³/s. Two units of 40 MW have been installed for power generation. The four DVC dams are capable of moderating floods of 651,000 cu ft. /s (18,400 m3 /s) to 250,000 cu ft./s (7,100 m3 /s). The Panchet Dam has a storage capacity of 170.37 million m3 to dead storage and 1497.54 m3 to top of gates. The reservoir covers an area of 27.92 km2 at dead storage level, 121.81 km2 at maximum conservation pool and 153.38 km2 at top of gates. Salient features of Panchet Reservoir:

DISCUSSION:- INTRODUCTION:- Hydroelectricity is the term referring to generated by hydropower, the production of electrical power the use of the gravitational force of falling or flowing water. It is the most widely used from of renewable energy. Once a hydroelectric complex is constructed, the project produces
  9. 9. PAGE 7 no direct waste, and has a considerably lower output level of the greenhouse gas Carbon Di-Oxide (co2) than fossil fuel powered energy plants. Worldwide, an installed capacity of 777 GVe supplied 2998 TWh of hydroelectricity in 2006. This was approximately 20% of the World’s electricity, and accounted 88% of electricity from renewable sources Hydroelectricity is electricity that made by the movement of water. It is usually made with dams that block a river or collect water that is pumped there. When the water start flow the huge pressure generates behind the dam forces the water down shafts that lead to turbine, this causes the turbine to turn, and electricity produced. IN a HYDEL POWER STATION there are two steps to produce the Electricity- 1) POWER GENERATION ENERGY CONVERTION:Here the potential energy of water is converted to kineticenergy (by opening of lock gate) & the kinetic energy converted to electrical energy (by help of alternator). ELEMENT: NAME WORK or OPERATION 1. Intake gate Controlling the water flow. 2. Lock gate Control the flow rate of water from reservoir. 3. Pen stoke Water flowing through it. 4. Impulse turbine Rotating the alternator shaft.
  10. 10. PAGE 8 5. Axial bearing & Radial bearing Coupling the turbine ,alternator shaft, provide protection from vibration &swaying sideways 6. Alternator Converting the mechanical power to electrical power. 7. Oil pressure tank Supplying compressed oil for opening & closing wicket gate & angle setting of runner blade. 8. Compressor Compressed the air in high (800PSI) pressure. 9. Governor oil pump Supply the oil to the oil tank. 10. Servo motor Controlling the angle of the runner blade & wicket gate. 11. Wicket gate Supply the water from pen stoke to runner blade. 12. Brush & slip ring Supply dc to alternator field winding 13. Air tank Store the compressed air. 14. Cooling Equipment Cooling the equipment. 15. Mechanical Break To stop the alternator rotation. 16. Battery Using for power back up. 17. Pressure Sensor To sense the pressure. 18. Temperature Sensor To sense the temperature. 19. E.O.T Crane To transfer the heavy equipment. 20. Wire For electrical connection. OPERATION: At first the oil from the oil tank supply to the oil pressure tank by help of G.O.P & the compressed air is also supply to it for getting required pressurized oil. Then oil is supplied to the servo motor for opening the wicket gate & angle setting of the runner blade. Then water flow through wicket gate & fall in the runner blade of impulse turbine which for the turbine shaft start to rotate.
  11. 11. PAGE 9 Due to axial & radial bearing armature shaft start to rotate. Now DC supply connected to the alternator field winding by brush & slip ring for excitation the field which for rotating magnetic flux will be created. Now the armature winding cut the magnetic flux and generating the emf in stator windingbecause E=d𝜙/dt (𝟇=Flux,E=emf) for that we get 11 kv 3 phase AC supply. 2)POWER TRANSMISSION INTRODUCTION: Here the generating power is transmitted for domestic, industrial & own axillaries’ purpose. EQUIPMENT: NAME TYPE OPERATION Transformer 11kv/415v,11kv/132kv,132kv/33kv,33kv/11kv Step up & Step down the voltage.

PAGE 11 i) Maithon&Kumardubi for industrial purpose. ii) Step down transformer for generating 11kv due to own axillaries’ and domestics purpose.in case of domestics purpose the 11kv is converted to 415 volt and supplied.in case of own axillaries’ the 11kv is used for AC supply in machine and after converting 415 volt charge the DC battery for DC supply due to power back up. 2.415v by a step down transformer: This 415 volt used for own industrial purpose. PRECAUTION Introduction: In order to ensure the proper running and working of the PowerStation we need to take certain steps that will be beneficial for us to run the PowerStation. Type of precaution: there are many type of precaution some are given below
  14. 14. PAGE 12 1. Fire precaution’s: Halon and carbon dioxide system for GT units. ii) Foam, Hydrant point (17no.s) for plant. iii) In every equipment a RTD is connected to sense the temperature and for protection we used alarm and trip configuration. 2. Power Continuity Precaution: In case of power failure continuity the power supply we used i) Diesel generator & Battery. ii) Inter connected grid. 3. High head precaution: In case of high water level a mercury sensor system is attached to sense the water pressure and according to the situation an alarm has been raised. 4. Lightning Precaution: Lighting arrester is used for save the equipment from lightning. 5. Plant worker precaution: For plant worker safety we used Helmet, High insulation Shoes, etc. CONCLUSION Advantages of Hydroelectricity: 1) The way the electricity is produced doesn’t harm the environment as much as fossil fuel like oil or coal. 2) Hydroelectricity is immense and safe and produces no waste and it causes no pollution.
  15. 15. PAGE 13 3) Hydroelectricity can be made very quickly and it is useful for times when demand is high. 4) Water that has been stored in a dam can be “let go” when needed, so the energy needed can be made quickly. Dis-advantages of Hydroelectricity: 1) The building of large dams to hold the water can damage the environment. 2) The huge place occupied by the dam causes land loss. 3) In the outlet of Hydel power station a huge amount of oil mixed in the dam water causes water pollution. For these reasons, Scientists are concerned about many problems with the dam, such as pollution, silt and the danger of the dam wall breaking to make this Hydel industry more scientific and customer friendly.
