| Claims The invention claimed is: 1 . A wind turbine system, comprising: A nacelle includes hub, rotor blades, gearbox, yaw drive system and the other components as in the horizontal axis wind turbine system. The generator is located on the ground of the tower. The rotation of the rotor in the nacelle will be transmitted to the generator on the ground via a vertical long axis perpendicular to the nacelle. The rotor is connected in the nacelle to a single right angle gearbox, which is connected to the vertical axis. This axis transmitting the rotation down to a double angle gearbox which is connected to 2 generators on the ground. 2. The wind turbine system according to claiml , wherein the nacelle includes all the components of the HAWT except the generator. 3. The wind turbine system according to claim 1 , wherein the generator is located on the ground of the tower. 4. The wind turbine system according to claiml , wherein the rotor is connected to the horizontal shaft of a single right angle gearbox in the nacelle. 5. The wind turbine system according to claiml , wherein the vertical shaft of the single right angle gearbox in the nacelle is connected to a long vertical axis perpendicular to the nacelle. 6. The wind turbine system according to claiml , wherein the long vertical axis is connected down on the ground of the tower to the vertical shaft of a double right angle gearbox. 7. The wind turbine system according to claiml , wherein the double right angle gearbox is connected to 2 generators on the ground. 8. The wind turbine system according to claiml , wherein the 2 generators are located on the ground, the direct drive generators will be more manageable in this invention. 9. The wind turbine system according to claiml , wherein the 2 gearboxes are of high gear ratio 1 : 100 this will overcome the reduction of torque resulting from moving the vertical axis and frictions inside the 2 gearboxes. 10. The wind turbine system according to claiml , wherein the rotor is still horizontal (HAWT) and generators are on the ground (VAWT), so this invention is the mixed wind turbine system (MSWT). |
MSWT
1 - Technical Field
The present invention relates to wind turbine systems.
2- Background Art
As already known from the prior art, that wind turbine is a device that converts kinetic energy from the wind into electrical power.
Main disadvantages are ...
- High costs for foundations and towers to carry heavy
generators.
- Difficult maintenance processes for generators at this height.
- The more powerful generators, the larger swept area / tower.
- Negative effects of cold and ice on the heavy generators.
3- Disclosure of Invention:
In mixed system wind turbine (MSWT)...
The nacelle will includes all the components as in HAWT
(Horizontal axis wind turbine) except the generator. The generator in MSWT will moved to the ground of the tower. The rotation of the rotor in the nacelle will be transmitted to the generator on the ground via a long vertical axis perpendicular to the nacelle. The rotor is connected in the nacelle to a single right angle gearbox, which is connected to the axis. The axis transmitting the rotation down to double angle gearbox which is connected to 2 generators on the ground.
The high step-up rotation of these 2 gearboxes will overcome the reduction of torque resulting from moving the vertical axis and frictions inside the 2 gearboxes.
Direct drive generators are more manageable in this invention.
Mixed system wind turbine (MSWT) providing ,
-Duplicates the electrical output for each tower.
-Reducing the high costs for foundations and towers.
-Facilitate the maintenance processes for generators.
-Reducing the swept area / power output / tower.
-Reducing the negative effects of cold and ice on the
generators.
