Wind Power Generation?
|
|
|
| |
 Technology to supply the electricity generated by converting the wind power into a rotating power to electronic devices
and users
Theoretically, 59.3% of the wind power can be converted into electronic energy but considering the efficiency of wingĄ¯s
shape, mechanical fraction, generatorĄ¯s efficiency, only 20~40% of them can be used as actual electronic energy.

Structure(Rotating Axes) Types |
|
|
| |
 |
Rotating axes are horizontal to the ground
Use wind at a high altitude
High aerodynamic efficiency
Affected by wind directions
Use for the Mid-Large Scale
ex)Propeller Type
|
 |
Rotating axes are vertical to
the ground
Not affected by wind
directions
Expensive materials, low
efficiency against horizontal
axes
Less than 100kW
ex) Darrieus Type, Savonius
Type

Advantages/Disadvantages of Wind Power Generation |
|
|
| |
 |
| |
Unmanned and remote control system require a low maintenance cost and almost no fuel cost
Since the windĄ¯s kinetic energy is used, it can be a solely and excellent alternative to fossil fuel, which can also
secure price-competitiveness against fossil fuel soon
No air pollution, clean and eco-friendly energy source
High initial cost but needs a short period of time for construction and installation
Due to the installation at a high height, the ground can be used for agriculture, stock-farming and others
In some areas, available for tourist attractions
|
| |
|
| |
|
| |
Since the generation is not possible in not windy areas, the installation is limited to certain areas
Sensitive to environmental change such as barriers so, thorough reviews are required for locations in developing.
Very high initial cost
Facility utilization rate is lower than other generators, may differ from locations.
Since the generation makes noise, a certain distance should be secured from villages. |
