A NEW FLOATING WIND ENERGY GENERATOR
KEYWORDS: Floating wind farm, wind turbine, wind power, electrical generator
This new wind turbine is floating at high altitudes and consisted of several parts The first part is a cicular inflatable structure as seen in the image Fig1 This circular part that is filled with a lighter than air gas and is floating over the ground at a high altitude This structure has four aluminum rings These ring keeps the strengthen the the circular structures There are four aluminum bars also as diameter of the the circular structure The diamtere of structure is 10 meters The thinkess of the structure is 4 meters .
Fig. 1. The circular structure filled with helium gas lighter than air gas keeps is floating at a high altitude.
The second part is a metal bar connects the center of circular structure to ground based generator as seen in Fig2 This metal bar is made of compressed carbon It is light weight and strong It acts as the shaft of the circulart structure and when the circular structure turns the bar also turns.
Fig. 2. The shaft of the ciruclar structure which is a strong light weight bar.
The third part is a electrical generator positioned on the ground and it is turned by the metal bar as its prime mover as shown in Fig3 It is a permanent magnet electrical generator The generator is fixed on the ground The genertor shalf is connected via joint to the carbon-bar (shaft of the circular structure) This joint allows the bar to rotate the electrical generator shaft at different angles Because the shaft of the circular structure is not vertically connected to electrical generator shaft Depends on the wind speed the ciruclar structure causes the carbon-bar aligns at different angles compared to the ground.
Fig. 2. The ground-based electrical generator that is rotated by the shaft of the circular structure.
The third part is the Gas Filled Savonius Style (GFSS) wind turbine are connected to the circular structure and they turn it GFSS are cylandrical shap structure that is filled with ligher than air gas This type of wind turbines are savious shape wid turbine It turns around its horizontal axis GFSS has diamtere of 3 meters and length of 6 meters The GFSS wind turine not only pull the circular structure but also turns around itself because a small permanent magnet generator is connected to the shaft of this GFSS wind turbine One one of such GFSS wind turbine connected to the circular structure shown in Figure 4.
Fig. 3. Gas Filled Savonius Style (GFSS) wind turbin connected to the circular structure.
In fact totally 7 GFSS wind turbines are connected to the cicular structure Once the wind blows, these turbines not only rotate around and generates electricty but also they pull the circular struture and rotate it as well as shown in Fig5.
Fig. 4. Seven GFSS wind turbines connecred to the ciruclar structure.
As seen in Fig6, the GFSS wind turbines are floating at a higher altitude than the circular structure They are tetherd to the cicular structure Each GFSS wind turbine is connected to the cicular structure using two tethers as shown in Fig 6.
Fig. 5. The seven GFSS wind turbines rotate altogether the ciruclar structure causes rotation of the carbon-bar rotates the ground based generator.
The generated electricity by the generator of the GFSS wind turbin transferred to the circular structure via the tethers and then from there is tranfered to ther ground via that bar becase a cable also is inside of the bar At the ground station, two electrical brushes get the electrical energy from the bar In fact the long bar transfer both electrical and also machnical energy.
Fig. 6. The carbonbar transfers both electrical energy and mechanical energy from the floating circular structure to the ground.
Considering a 10 meter diameter circular structure and thinkess of 4 meters, with GFSS turbine with diamtere of 3 meteres and lenght of 6 meters, the generated electricty at wind speed of 30km/h will be 18KWh. At very high speed the deviation angle of whole floating wind turbin to the ground will be low but it still will be at a high altitude and generates electricty according to calculations. A floating wind farm using such new floating windturbin also designed and its output power stimated. A wind farm with area of 1km x 1km with 200 number of such wind turbine can generate 3600Kwh in wind speed of 30k/h.
The proposed wind turbine occupy lower area as it is floating at higher altitude and only the ground is on the ground occupy a small area Also this new wind turbin can be used to make floating wind farms that has minimum enviromental beauty effect Because this wind turbin floating at higher altiutude and not visible from the ground This new wind turbin also generate more energy as it benefits high altitude winds that has higher wind speed and more consistent wind speed.
Due to greenhouse problem of the fossile fules which are limitted as well, there is a active seeking for extraction of renewable energies because electrical energy consumption also increasing worldwide Renewable energy generation technologies including wind power, solar power, water power, biomass, and nuclear power has several problems of cost or low efficiency To alleviate these problems a new airborn floating wind turbine propsoed The wind turbin floats at high altitude and generates electrical energy The propsoed floating wind turbine system parts explained in detail and it output power estimated and also a floating wind farm using such floating wind turbine also considered and its output power estimated Finally advantage of this floating wind turbine are explained.
