The present invention relates to a novel wind turbine power system. More particularly, this invention pertains to a wind turbine power system having a twin directional turbine / generator / alternator (with or without permanent magnets A/C, D/C machine) wherein the rotor and stator (which may be of different types including but not limited to flange/fly wheel types of rotor and stator) is moving in opposite direction such that, if rotor moves clock wise at the same time stator moves anti-clockwise and vice versa in order to generate more energy despite of lesser wind velocity. BACKGROUND OF THE INVENTION

With the depletion of hydrocarbon fuels and increasing emphasis on environmental impact, alternative sources of energy have been sought. One source of alternative electrical energy is wind machines. Such wind machines have a number of disadvantages.

Due to increase in the carbon emission in the environment, it has become necessary to opt for green energy which is now-a-days achieved through many ways like solar, wind, tidal, etc. In all these practices we can produce pollution free energy but there are some major drawbacks to them. One of them is that it is not economically viable. For e.g.: about 8 to 10 years are required to recover the cost of one windmill. In general the existing windmills produce about 30 % energy of their installed capacity throughout the year (kw/h basis) however there is no consistency because of the fluctuation of the wind speed -as per the geographical distribution. As shown in following power ^■ curves. - Windmills are designed to produce energy at its full capacity with a wind velocity of about 50kmph (approx). Wind is not constant anywhere in the world. In the entire year, the wind does not even flow at about 50 kmph [or more] speed for the span of about 15 to about 20% of the total time [total calculation] If wind, velocity drops at 50% (25kmph), then the turbine produces 1/5 or 1/6 energy of the installed capacity and that is why the turbine produces about 30% energy [kw/h annual basis] of their installed capacity, hence they are not commercially viable.

DEAT AILED DESCRIPTION OF THE INVENTION

Throughout the following description specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily ¹ obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense.

As shown in figures the present invention is directed to a novel wind turbine power system. More particularly, this invention pertains to a wind turbine power system having a twin directional turbine / generator / alternator (with or without permanent magnets A/C, D/C machine) wherein the rotor and stator (which may be of different types including but not limited to flange/flywheel types of rotor and stator) is moving in opposite direction such that, if rotor moves clock wise at the same time stator moves anticlockwise and vice versa in order to generate more energy despite of lesser wind velocity.

As shown in figure 1, there is provided a main static shaft (12) which is devoid of rotation and fixed by a nut (60) with the structure or base plate (32). Before fixing this static shaft(12) to the base plate(32),we have to fit bearing (26) on the static shaft(12), on this bearing(26) lower flange(44) of the stator body is mounted and bearing(26) is tightened by the nut (58), on the lower side of said flange (44), a commutator (46) and brush (38) is attached.

To this static shaft (12), there is one more bearing (48) on which the main hollow rotor shaft (16) is mounted vertically, followed by another bearing (50) which are mounted on the top of the same rotor shaft. Further a nut (28) is tightened to hold the bearing (50) on the main shaft (12).

The stator body (20) with the stators (22) is mounted on the lower flange (44) with the plurality of bolts (30). The upper flange of the stator body (18) is couples with the stator body with the bolts (30) and between this flange and the main hollow rotor shaft (16) there is one bearing (52) fixed.

The second hollow rotor shaft (14) holds bearing (52) and said shaft coupled with the main rotor shaft (16) with the plurality of bolts (30) there provided a fixed flange (40), a commutator (36), and brush (38) to the shaft (14). On the top of this shaft (14) one more bearing is fixed (54) by a nut (62).

In said vertical axis wind turbine, the previously mentioned twin directional generator/alternator/turbine (fig.l) is used. In said design, the turbine is fixed (70) on the vertical shaft (82) which is extended downwards and coupled between flange (32) and vertical pole (80), flange (84) is used for coupling said shaft (82) to flange (32). Further, one end of a set of blade (76) is fixed to stator body flange (44) and the other end of the same set is fixed to the vertical shaft (82) with the help of bearing (78). The setting of said blades is made such that they will rotate in the opposite direction to rotor blades. Further, static shaft (72) is extended upwards and coupled with main static shaft (12) with the help of flange (74). Further one end of other set of blade (66) is fixed to the rotor flange (40) and the other end is fixed to the shaft (72) which is extended upwards again with the help of bearing (64). The setting of said blades is made such that they will rotate in opposite direction to stator blades (76).

There will be a supporting structure (68) provided which will hold and give extra strength to the complete assembly of this wind turbine and arrow (86) and (88) which is shown in the drawing depicts the direction. In a given arrangement if permanent magnet is used then there will be only one commutator in the said arrangement when the said arrangement is used as a vertical axis, the axial load action downwards is taken up by the thrust bearings, Radial loads can cause dynamic unbalance of rotor and thrust bearing alone can not take up the radial loads, hence an additional bearing which is also refer to as guide bearing is provided to said arrangement of turbine. More than one guide bearing is used as per the design and loads thereby number of bearings changed accordingly.

The said arrangement provided with a wiring harness (34) which connects to the rotor and commutator / stator and cummutator. Another wiring harness (56) connects to the grid or direct use of energy of the said system. There air gap (42) is provided between the rotor (24) and the stator (22).

While a number of exemplary aspects and embodiments have been discussed above, those of skill in the art will recognize certain modifications, permutations, additions and sub-combinations thereof. It is therefore intended that the following appended claims and claims hereafter introduced are interpreted to include all such modifications, permutations, additions and sub-combinations as are within their true spirit and scope.
