BACKGROUND OF THE INVENTION
[0001 ] Hydro electricity is another term for power generated by harnessing the power of moving water. Not necessary falling water, just moving water. There are many famous such generating stations in the world, not the least of them at Niagra Falls, Grand Coulee and Boulder Dam. These are just a few of the many examples of energy produced by falling water. On the other hand, a small mill set in the rapids of a fast moving stream is also an example of it in action, on a lesser scale. The truth is that any steady current of flowing water from a river or other waterway can be converted to power.
HOW 1$ HYDRO ELECTRICITY GENERATED
[0002] Power is generated or "manufactured' in large power generating stations using the same basic principle as a small grist mill yet on a much larger and vastly improved scale for better efficiency. These electrical generators are attached to massive turbine devices which spin at great speeds as a result of water rushing through them. These power station turbines are much more efficient at extracting the kinetic energy from the moving water and converting that energy it into power through these generators.
[0003] The Hydro Electricity extracted from water depends not only on the volume but on the difference in height between the source and the water's outflow. This height difference is called the head. The amount of potential energy in water is directly proportional to the head. To obtain very high head, water for a hydraulic turbine may be run through a large pipe called a penstock.
[0004] For instance, energy is derived to make power by the force of water moving from a higher elevation to a lower elevation through a large tube "otherwise known in technical terms as a "penstock". When the water reaches the end of the penstock, it turns a water wheel or 'turbine" at enormous speeds. The turbine rotates via a connected shaft to an electrical generator, and this generator creates electricity, ft is the turbine and generator working in combination that converts 'mechanical energy' into 'eclectic energy'. The water that makes it possible is a renewable energy resource, just like the wind that turns the turbine attached to a generator.
[0005] Hydro Electricity may be extracted from water but it depends not only on the volume of water but also on the difference in height between the top of the penstock and where the water spins the turbine. This difference in height is often referred to as the 'head'. From this 'head', it can be determined the exact amount of potential energy that can be converted. Therefore, it is advantageous to build power dams as high as possible to convert the maximum energy from mechanical energy.
[0006] while many Hydro Electricity generating stations supply world power grids, some projects are created for private business purposes. For example, aluminum manufacturing companies require large amounts of power. And there are many other examples of industries that use hydro electricity in their manufacturing operations.
[0007] While hydro electricity seems relatively clean and safe in comparison to burning fossil fuels (coal or oil or natural gas), nearly all large hydro electric installations in North America have significant had impacts on nearby environmental habitats once they are brought online. This is because they significantly impede the flow of water in rivers and lakes at the point where the generating dam is installed. In turn, this causes significant increases in water in rivers and lakes at the point where the generating dam is Installed, in turn, this causes significant increases in water levels in corresponding upstream water systems while at the same time creating much lower water levels downstream. Hydro-Electric Energy; Flowing water is used to push turbines which generate electricity. Several steps can be taken to maximize the power provided by hydroelectric plants like storing water by using a dam to increase the height the water will fall and thus giving the water a higher potential energy, thus increasing the flow of water (speed) by diverting part of the waterway to other paths or using the natural drop of the waterway to power the Hydro-Electric plant. The flow to a lower level, causes electric generation; therefore, the higher mass flow rate (amount) of water per time period * speed), the more energy generation that can occur. For prior art reference is made to Fig.1.
[0008] Dam - Most hydropower plants rely on a dam that holds back water, creating a large reservoir. Often, this reservoir is used as a recreational lake, such as Lake Roosevelt at the Grand Coulee Dam in Washington State.
[0009] Intake - Gates on the dam open and gravity pulls the water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe.
[0010] Turbine - The water strikes and turns the large blades of a turbine, which is attached to a generator above it by way of shift. The most common type of turbine for hydropower plants is the Francis Turbines, which looks like a big disc with curved blades. A turbine can weigh as much as 172 tons and turn at a rate of 90 revolutions per minute (rpm) according to the Foundation for Water & Energy Education (FWEE).
[0011] Generators - As the turbine blades turn, so do a series of magnets inside the generator. Giant magnets rotate pas copper coils, producing alternating current (AC) by moving electrons. (You'll learn more about how the generator works later).
[0012] Transformer - The transformer inside the powerhouse takes the AC and converts it to higher-voltage current.
[0013] Power lines - Out of every power plant come four wires; the three phases of power being produced simultaneously plus a neutral or ground common to all three. (Read How Power Distribution Grids Work to learn more about power line transmission). [0014] Outflow - Used water is earned through pipelines, called tailraces, and re- enters the river downstream.
SUMMARY OF THE INVENTION
[0015] Hydroelectricity or hydroelectric power is the electricity obtained by harnessing the power of water flowing down from a high level. It is a timeless and renewable resource.
[0016] Huge generators convert the potential energy of falling or fast moving water into electrical energy. The potential energy of the water is first convened into mechanical energy and then into electrical energy.
[0017] Water, usually stored in dams, is led down through large pipes or tunnels to lower levels, and in the course of the fall, the water rotates turbines. The mechanical energy produced is converted to electricity by the generators connected to it. The structure that houses the turbines and generators is called the powerhouse. Transformers change the alternating current produced by the generators into current of very high voltage for easy transmission through long distances.
[0018] Hydropower is one of the three principal source of energy used to generate electricity, the other two being fossil fuels and nuclear fuels. Hydroelectricity has certain advantages over these other sources: it is continually renewable thanks to the recurring nature of the water cycle, and causes no pollution. Also it is one of the cheapest sources of electrical energy.
[0019] ltaipu Dam between Brazil and Paraguay, which is 190 meters high and generates more than 12,600 MW, is the largest hydropower dam in the World. (The 185 metre Three Gorges Dam, now being constructed in China on the upper Yangtze River, would take its place by 2009, producing 18,200 MW of power). The Grand Coulee Dam, located near Spokane, Washington, is the largest hydropower darn in the United States, producing 6,480 MW. The Rogan Dam, in Russia, the tallest in the world, is 335 metres high. The Orovilie dam, (ocated in California, the tallest in the United States, is 235 metres high.
[0020] Let us assume that at a very low speed of water flow the previous water turbine is not capable of producing electricity. As per the presently invented Cyclonic Hydro Power Plant is a modified water turbine through which the water flow irrespective of speed is slow or fast will enter the set of specially designed disc and convert into high pressure. Another major fact is that its installation cost will be much cheaper than the previous water turbine and also the maintenance cost will be much cheaper. The effect of the water pressure which hits the rotor blades works in between 90 degree and splash out 0-50 degree and splash out 0-50 degree outwards. The result will be constant production of electricity all the time.

DESCRIPTION AND WORKING OF THE VARIOUS PARSTS.
1. Set of fixed blades:
[0026] The full assembly is divided into required number of concentric set of fixed blades. The number and size of the concentric set of fixed blades are different. The concentric sets of fixed blades are designed to get equal torque on concentric parts for a particular design velocity.
2. Set of rotating blades:
[0027] Though the diameter and the division of the set of rotating blades is similar to that of the assembly of fixed blades but unlike fixed blades they are designed for maximum momentum change. This assemble of rotating blades is placed behind the fixed blade system and is directly connected to the shaft which in turn is attached to the dynamo via a coupling through a gearbox. This system of rotating blades utilizes the water converged by the fixed blades. 3. Ball Bearing:
[0028] It is used to support the moving shaft on the fixed blade frame. This technology is generally used to reduce friction. Due to the presence of impurities in water, the ball bearing, on which all the parts rotates (except front blades) smoothly should be covered by the double "Z" and the rubber seal protection.
4. Shaft:
[0029] The basic function of the shaft is to feed the dynamo with the angular velocity attained by the rotating blades. The various parts of the generator are connected along the length of the shaft with or without the use of ball bearing.
5. Gears:
[0030] Gears are provided to convert the high torque of the rotor blades to the necessary RPM. It is placed between the shaft and the coupling. The gears that should be provided here is of the step-up-type.
6. Brakes:
[0031] Brakes are provided on the low speed shaft to govern the speed of the shaft. Brakes helps control the output RPM of the shaft.
7. Coupling:
[0032] The coupling connects the shaft with Hie dynamo.
8. Dynamo:
[0033] This part of the generator is used to convert the mechanical energy (angular velocity) attained by the rotating blades into electrical energy. 9. Structure of the blades of the fixed blades:
[0034] The blades of the fixed disc change the direction of the flowing water at an angle of about 85 through the perimeter The fixed blades convert the motion of the incident water into cyclonic water at its exit
10. Structure of the blades of the rotating blades:
[0035] Rotating blades utilize maximum energy of the incident water from the fixed blades. The incident water experiences a momentum change, which exerts a pressure on the blades, which results in the circular motion of the blades. There are two types of blades used. One type of blades is placed radically from the center which utilizes most of the energy of the water incident from the fixed disc. The blades are nearly semi cylinder in shape.
[0036] The other type of blades is placed on the circumference. The water is directly incident on these blades, which brings about the circular motion of the disc at high speed. This process can improve the speed of the rotating disc.
11. Frame to hold the front disc:
[0037] This is the main framework of the generator. It supports the front disc as well as the other fixed parts of the generator.
12. Base of the whole structure:
[0038] Base of the whole structure is made quite strong so that not only it can withstand the dead weight of the generator bui also can take care of the huge moment coming due to the flowing of the water.
13. The point of water incidence:
[0039] his is the point where the water is coming at angle of 90 degrees and creates a pressure on rotating disc to rotate it at high speed and also increase the speed of rotation.
