Presentation=sardar sarovar hydro power plant

  2. 2. ESSENTIAL FEATURES OF HYDROELECTRIC POWER PLANT <ul><li>Catchment area: - </li></ul><ul><li>The whole area behind the </li></ul><ul><li>dam draining into streak or </li></ul><ul><li>river across which the dam is </li></ul><ul><li>been built at a suitable space </li></ul><ul><li>is called catchment area. </li></ul>
  3. 3. 2) Reservoir : - The reservoir is employed to stored water, which is further utilizes to generate power. It may be generally of two types. a) Natural (e.g. SARDAR SAROVAR DAM) b) Artificial (dam) Water is held in upstream reservoir is called storage & behind a dam at a plant is called pondage. 3) Dam : - A dam is a barrier to confine or raise water for storage or diversion to create a hydraulic head. Dams are generally built are concrete for stone masonry, earth or rock fill or timber. 4) Spillways : - The rise of water level beyond the limit endangers the stability of dam structure. To relieve reservoir of the excess of after contribution, a structure is provided in the body of dam or near the dam or on the periphery of basin .this safeguarding structure is called spillway.
  4. 4. 6) Surge tanks : - A surge tank is a small reservoir or tank in which water level rises or falls to reduce the pressure swings so that they are not transmitted in full to a closed circuits. 7) Draft tubes : - The draft tube is a conduit, which connects the runner exit to the tailrace. 5) Conduits : - conduits are just simple channels of water that is they carry water from the turbine. They may be open like canals or closed like penstocks, tunnels and pipelines. 8) Penstock :-From the intake work are forebay water is taken to the turbine by a conduit system is known as penstock. There are two type of penstock. (a) Low pressure & (b) high pressure. High pressure penstock consists of channels or a pipe. Low penstock consists of a steel pipe which can take water under pressure.
  6. 6. POWER HOUSE There are two power houses for the Sardar Sarovar Project (SSP). (A) River Bed Power House (6 x 200 MW) and (B) Canal Head Power House (5 x 50 MW). Power benefits are shared among Madhya Pradesh, Maharashtra and Gujarat in the ratio of 57:27:16 respectively.
  7. 7. <ul><li>RIVER BED POWER HOUSE (RBPH) </li></ul>The RBPH is an under ground power house stationed on the right bank of the river having six number of Francis type reversible turbines each of 200 MW installed capacity. The T.G. Sets are supplied by M/S Sumitomo Corporation, Japan and M/S BHEL. The 400 KV Switchyard is indoor type having Gas Insulated Switch Gear and Bus-bars. Total Energy generation from this power house up to 31/12/2008 is 11058.456 MUs.
  8. 8. (B) CANAL HEAD POWER HOUSE (CHPH) The CHPH is a surface power station in a saddle dam on right bank of the reservoir having total installed capacity of 250 MW (5 x 50 MW). These units can be operated with minimum reservoir water level of 110.18 meters.
  9. 9. POWER BENEFITS <ul><li>The power from SSP is to be generated from a 1200 MW powerhouse </li></ul><ul><li>at the dam and a 250 MW powerhouse at the head of the canal. </li></ul><ul><li>However the power actually produced will be much less than the </li></ul><ul><li>installed capacity, mainly because increasing amounts of water will </li></ul><ul><li>be diverted into the canals, reducing the volume of water available to </li></ul><ul><li>flow through the turbines at the dam. </li></ul><ul><li>Pumping water to the Kutch and Saurashtra branch canals would </li></ul><ul><li>consume around 70 megawatts after allowing for the small amounts </li></ul><ul><li>of power generated by turbines in the canal system. </li></ul>
  10. 10. BENEFITS OF SARDAR SAROVAR DAM <ul><li>IRRIGATION : The Sardar Sarovar Project will provide irrigation </li></ul><ul><li>facilities to 17.93 lac ha. of land, covering 3112 villages of 73 talukas </li></ul><ul><li>in 15 districts of Gujarat. It will also irrigate 75,000 ha. of land in the </li></ul><ul><li>strategic desert districts of Barmer and Jallore in Rajasthan and </li></ul><ul><li>37,500 ha. in the tribal hilly tract of Maharashtra through lift. </li></ul><ul><li>DRINKING WATER SUPPLY : A special allocation of </li></ul><ul><li>0.86 MAF of water has been made to provide drinking water to 135 </li></ul><ul><li>urban centers and 8215 villages within and out-side command in </li></ul><ul><li>Gujarat. Water supply requirement of several industries will also be </li></ul><ul><li>met from the project giving a boost to all-round production </li></ul><ul><li>FLOOD PROTECTION : It will also provide flood protection to </li></ul><ul><li>riverine reaches measuring 30,000 ha. covering 210 villages and </li></ul><ul><li>Bharuch city and a population of 4.0 lac in Gujarat. </li></ul>
  11. 11. ADANTAGES OF HYDRO POWER PLANT: <ul><li>No fuel charges, </li></ul><ul><li>Running cost almost nil, </li></ul><ul><li>No stand by losses, </li></ul><ul><li>Highly reliable, </li></ul><ul><li>Efficiency does not decrease with time, </li></ul><ul><li>Construction and operation wise very simple, </li></ul><ul><li>Maintenance cost very less, </li></ul><ul><li>Starts quickly and synchronizes fast, </li></ul><ul><li>Minimum staff when plant is operational, </li></ul><ul><li>No ash problems thus pollution free, </li></ul><ul><li>Also useful in flood control and irrigation and drinking water </li></ul><ul><li>purpose, </li></ul><ul><li>Comparatively quiet long life </li></ul>
  12. 12. DISADVANTAGES OF HYDRO POWER PLANT: <ul><li>Higher initial cost, </li></ul><ul><li>Takes long time of erection, </li></ul><ul><li>Plants are setup at distant places so transmission losses increases, </li></ul><ul><li>Totally dependent on the availability of water, </li></ul><ul><li>Larger area required, </li></ul><ul><li>Period of installation time is high, </li></ul>
  13. 13. CONCLUSION <ul><li>By sardar sarovar hydro power plant we produce </li></ul><ul><li>maximum 1450 MW electricity. </li></ul><ul><li>As decided by the government out of them 16% </li></ul><ul><li>electricity given to the Gujarat. </li></ul><ul><li>In this power plant we can produce electricity by </li></ul><ul><li>two way. </li></ul><ul><li>One is RIVER BED POWER HOUSE (RBPH) and </li></ul><ul><li>another is CANAL HEAD POWER HOUSE (CHPH). </li></ul><ul><li>By RBPH we can produce 1200 MW electricity and </li></ul><ul><li>by CHPH we can produce 250 MW electricity. </li></ul>
