Abstract

Mixing both vertical and horizontal types of wind turbine systems in order to maximizing the power output and minimizing the costs of power production and maintenance.

Description

Mixed System Wind Turbine (Vertical + Horizontal)
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.
