FIELD OF THE INVENTION:
-This invention relates to the field of Renewable Energy sources.
-More particularly, this invention relates Electricity generation with the help of Wind
Mill.
-More particularly, this invention relates to Portable Wind Hovered horizontal axis wind
turbine which can generate electricity even at low wind velocity at remote locations away
from main power grid or electricity lines.
BACKGROUND OF THE INVENTION:
In many countries wind energy has become an indispensable part of the electricity generation mix. The opportunity for ground based wind turbine systems are becoming more and more constrained due to limitations on turbine hub heights, blade lengths and location restrictions linked to environmental and permitting issues including special areas of conservation and social acceptance due to the visual and noise impacts. In the last decade there have been numerous proposals to harness high altitude winds, such as tethered kites, airfoils and dirigible based rotors. These technologies are designed to operate above the neutral atmospheric boundary layer of 1300 m, which are subject to more powerful and persistent winds thus generating much higher electricity capacities. This work presents an in-depth review of the state-of-the-art of high altitude wind power, evaluates the technical and economic viability of deploying high altitude wind power as a resource.
The Problems in the existing methods of wind turbine :-
1. Wind power must still compete with conventional generation sources on a cost basis. Depending on how energetic a wind site is, the wind farm might not be cost competitive.
2. Even though the cost of wind power has decreased dramatically in the past 10 years, the technology requires a higher initial investment than fossil-fueled generators.
3. Good wind sites are often located in remote locations, far from cities where the electricity is needed. Transmission lines must be built to bring the electricity from
the wind farm to the city. However, building just a few already-proposed transmission lines could significantly reduce the costs of expanding wind energy.
4. Wind resource development might not be the most profitable use of the land. Land suitable for wind-turbine installation must compete with alternative uses for the land, which might be more highly valued than electricity generation.
5. Turbines might cause noise and aesthetic pollution. Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape.
6. Turbine blades could damage local wildlife. Birds have been killed by flying into spinning turbine blades. Most of these problems have been resolved or greatly reduced through technological development or by properly sitting wind plants.
PRIOR ART:
The use of wind turbines to generate electricity is well known in the prior art. These turbines generally include a super pressure balloon, Horizontal axis wind mill, A kite, Tethers, etc. Generating electricity from renewable energy sources has received a great deal of attention in the past few years. Yet conventional wind power generation have significant disadvantages. For example, wind speed and direction vary, making the amount of electricity generated by a wind turbine inconsistent. Presently in this method we use a balloon to keep a wind mill in suspended form in the air at high altitude. As at high altitude wind velocity is maximum so that more amount of power generation will be done by using small capacities of wind mills.
OBJECTS OF THE INVENTION:
- An object of the invention is that to provide portable wind mill and hence it can
be easily useful for electricity generation.
Another object of the invention is to generate electricity at location which suffered from natural disaster like earthquakes, floods etc.
- Yet another object of the invention to develop new method of renewable and
sustainable energy generation.
- Yet another object is to have cheap efficient electricity generation method.
- Yet another object is for surveillance.
Yet another object is for decoration, advertisement, etc.
SUMMARY OF INVENTION:
According to this invention, there is provided a system for wind hovered horizontal axis wind mill system comprises:
- The kite which is useful for providing drag and lift force for wind mills.
The Helium Balloon to take kite system at higher altitude and steady in the air .
- DC motors for electricity generation attached to kite.
The connection wire from generators attached to main storage device.
- When we take kite at higher altitude in the air due to drag and lift force wind
blades starts rotating.
Typically, in this existing system modifications are done for improving efficiency of wind mill by taking advantage of high altitudes air. Current system doesn't require stationary tower for mounting the wind mill, so the problem of vibrations and heavy foundation is removed.
