The components of wind turbines are a Generator, Gear box, Controller, Power Cable, Brake, Blade, Rotor and others. Each of these components has high cost and electric power will not be generated without each one. So each wind turbine tower is expensive to erect, and keep in mind that after each tower produces the electric power it needs to be collected, regulated and transmitted into one system or power station for use or transmission to end users. This also adds big expense. When there is electrical and mechanical failures in each tower, maintenance personnel have to climb up risking their lives every time to fix the electrical problem and this also adds more cost to the running cost.
This project is about building a new wind turbine that is very efficient in generating electric power with very low cost in comparison to the existing technology.
The main working principle of this new mechanism is instead of each wind turbine tower generating electric power individually, the wind turbine towers (6 towers in this design) combine their mechanical energy that is converted from the wind via the turbine blades into one mechanical rotating shaft energy that is collected with a mechanical system to be directed in to one generator to produce electric power. This will save cost big-time because instead of using 6 generators, 6 gear boxes, 6 controllers, 6 power cables and etc, this system use 1 electric generator, 1 gear box, 1 controller, 1 power cable and 1 other component for every 6 wind turbine towers. It also saves electrical maintenance cost because the entire electrical system will be on the ground and the maintenance personnel or inspection team will not have to go up onto the tower. Combining the 6 into 1 also produces same amount of energy because as they combine each tower, the torque will increase in multiplication of the number of the combined system. The other advantage of the mechanism is electric power collection is reduced in 1/5 because there will be 1 generator for every 6 towers.
The transmission of the mechanical system is done by using a gear transmission system composed of mainly a bevel gear and sun-and-planet gear. The bevel gear is used first on the initial mechanical rotating shaft that is generated by the wind turbine blades from the wind to transfer the horizontal rotation shaft to a vertical 90 degree shaft which is found inside the erected tower. Then the bevel gears are also used again next to transfer the rotating mechanical shaft back to the horizontal axis. Then combination of bevel gear and sun-and-planet gear will be used at the third step to collect the entire mechanical rotating shafts of each wind turbine tower into a rotating shaft that is perpendicular to each incoming horizontal shaft which comes from the individual tower. Then this shaft will be connected to 1 gear box which finally will be connected to 1 generator.
