Definitions

  • the present invention relates to electricity generation in already existing hydro electric power generating dam with sufficient number of generators working in it where my newly invented electricity generation system and method is added and the generation of electricity is increased to a very large extent.
  • Para 5 Electricity generation by use of solar energy is pollution free, renewable, available in plenty but till today it is costlier and not much achieved to meet our needs but day will come when it will come cheaper.
  • p a ra 6 Electricity generation by use of wind energy though renewable even if it satisfies the 100% need of a country, suddenly for a few day if wind is not there, at that time the electricity need of a country is to be met only by the generation from other sources, when there is wind again, the other sources to that extent need not run and either coal, gas, on oil or even water stored in an hydro electric dam can be saved. So even though to what ever extent the wind -energy is developed, W;ithout depending on it alone, the country should be ready to meet its 100% needs with other sources.
  • the one source which I have invented a system and method for large amount of electricity generation capability is the power generation in an hydroelectric dam.
  • the limitation to this is the water source availability of a country.
  • Para 11 Imagine for example a dam having maximum water storage height as 120 feet at a particular instant, when the stored water height is 15 feet in the dam, further when the water comes in the river, from the river water entrance point (the waterhead zero feet) it slowly drops in height by 105 feet and the water level of the dam comes up till the dam is filled to 120 feet.
  • this drop in height of the water from zero feet to the lower level of 105 feet downwards the water head lost within the dam is also a source of energy to be extracted and converted to electrical energy.
  • Para 17 Referring to the Publication Dinamaiar Tamil daily in Tamil Nadu south India in the case of mettur dam if taken as example.
  • Fig 2 The dam top view is shown.
  • fig 3 is showing the preparation of the dam in the back water of the dam at the river water entrance point to construct a water tank the hatched area I is dug to the depth of 90 feet from the maximum water storage level of dam to arrange the water jet in it (SI NO 24) and in front of the hatched area to provide pillars after construction to support the structure that will bear the arrangement to carry the hydroelectric generators in the hanging position the hatched area III is dug as in SI No 30.
  • SI NO 24 the maximum water storage level of dam
  • the HPG should be used it to generate power to handle the increased quantity more than 20000 cusecs the HPG the MW capacity has to be more than 200 mw but for the this the big size water tank construction expense, the increased capacity HPG expense and its erection structure expense all will be more. After meeting heavy expenses the river water excess flow should be available for a long period to get profit for so much expense.
  • the hatched area is cut to the width sufficient to carry 20,000 Cusecs to the place inside the dam where the sloping floor height is 30 feet from the dam bottom level (it is l/4 th of the total height)
  • the natcnecl area 11 is du 9 t0 a depth of 10 feet from the earth top. Through this water enters the water tank when the river water is blocked by shutters put up in the river entrance point to the dam as shown in fig 4 SI No. 39.

  • a small gap of 1 or 2 feet height is provided as shown in this 8 SI. No 106 so that to maintain constant water head inside the pipes the water level in the hatched area SL No 103 is always full and a small quantity of water will be overflowing to the dam through the SI No 106. It is taken care that the water goes out of all jets is slightly less than the quantity of water getting into the hatched area IV from the river. This excess water only goes through the opening 106.

Abstract

La présente invention concerne un procédé de génération d'électricité par utilisation d'une génératrice hydroélectrique en position suspendue à l'intérieur du barrage avec aptitude de réglage de niveau. Dans le barrage hydroélectrique existant, à l'intérieur du barrage, dans les eaux de remous du barrage, au niveau du point d'entrée d'eau de rivière du barrage, en construisant un réservoir d'eau, un jet d'eau peut être agencé. Ce jet d'eau peut faire en sorte qu'une génératrice hydroélectrique maintenue à l'intérieur du barrage juste au-dessus du présent niveau d'eau du barrage, fonctionne et que de l'électricité soit produite. Cependant, lorsque le niveau d'eau change vers le bas ou vers le haut la génératrice peut également être déplacée vers le bas ou vers le haut et verrouillée en position pour arrêter la vibration et il est possible de faire en sorte qu'elle fonctionne. En utilisant le procédé ci-dessus, le nombre d'unités d'électricité produites dans le barrage hydroélectrique peut être augmentée en grande mesure.
