FR2512887A1 - Electric generation for lower power consumption domestic heating - uses reduction gearbox to produce high torque at low speed from motor driven high speed by wind generator or mains - Google Patents

Abstract

The electric energy generation plant uses energy produced from low power sources such as wind generators or solar convertors, with the alternative of drawing energy from the mains supply when the other sources are not functioning adequately. The wind or solar sources generate a small electric power, sufficient to drive a motor which works into a reduction gearbox. The motor is driven at as high a speed as possible and the reduction gearbox produces at its output a relatively high mechanical torque at low speed to drive a large generator giving a power output much greater than the input power. This permits the reduction of the dimensions of the wind turbine and the mast mounted generating plant.

Description

 The present invention makes it possible, starting from a low-value electrical input power, produced either by an aerogenerator or by a source of solar energy> or quite simply the national grid, to have access via a motorcycle -reducer and generator located on the ground, to have an electrical power of use several times greater than that of input.

 In current wind turbines, the generator is integral with the rotation and drive device comprising the blades, the transmission axis, and sometimes mechanical acceleration systems.

All these assemblies being assembled in height on a pylon or mast.

 The mechanical power required to drive a GI generator is proportional to the size of the blades, the higher the power, the greater the surface swept by the blades. Similarly for the generators attached to the wind generator, the Congestion poses some problems because the speed of rotation of the generator is inversely proportional to the number of turns in the armature and the inductor, in order to have a high power generator with the lowest possible speed of rotation. dimensions of the generator will be very important, hence a considerable weight and a very difficult positioning at the top of the mast. To reduce this bulk, we intercalate between the transmission axis of the wind generator and the generator, mechanical accelerators, but this causes a very significant loss of power.

 So to obtain a high power output from the wind generator necessary for heating a home, large blades will be necessary or fragile, especially in the event of unfavorable weather conditions. 'the wind turbine is very difficult Qme if you have a' pylon or tilting mast.

 Sealing problems can also arise.

OPERATING PRINCIPLE.

With the help of an aerogenerator delivering a low electrical power, that being just necessary for the supply of a gear motor whose input rotation speed is as high as possible which allows to have in output from the gearbox a very high mechanical torque allowing the axis of another generator of higher power to rotate but with a much lower speed of rotation
In the case where the wind turbine produces electricity, the RI relay is avoided and the gearmotor is uncoupled from the network so as to use only the energy produced by the eolinne.

When the power cannot drive the wind generator, the network alone is used but with a consumption much lower than that of use.

It is obviously possible to use a solar energy source instead of the wind generator, which does not change the fundamental principle of the invention which constitutes a whole.

 It is also possible to continue the application and add a cascade of other gearmotor and generator sets.

 The device according to the invention has multiple applications: - In the case where the available power is insufficient for individual use.

-In the sense of saving energy since a low consumption of the network is necessary to heat a home, this saving can be even more significant in the case where one uses a backup source such as wind power or solar energy.

Claims (3)

 CLAIMS.  I. Set of electrical energy production associated with a low value energy source such as an aerogenerator, solar collector or national network, this energy will allow to drive a gearmotor having a very fast input rotation speed high which makes it possible to have at the output of the reducer a very high mechanical torque necessary for driving a power generator much larger than the input power but with a much lower rotational speed compared to that entry.  2. Electric power generation assembly according to claim I characterized by the fact that in the case where an adrogenerator is used as auxiliary power, (which in certain regions can become the main source of electrical energy) that the dimensions of the aerogenerator are much more; rnW reduced for the same power of use, therefore the reliability is increased.  3. Electric power generation assembly according to claim I, characterized by the fact that the gear motor and the generator can also be several hundred meters away from the wind generator or from any other input source.
