Description

Functional wind generation system

The present invention relates to a functional wind power generation system, and more specifically, it can be efficiently and compactly manufactured by breaking away from the complicated and expensive conventional giant wind power system, and in particular, the functionality capable of producing electricity even when the wind is not blowing. It relates to wind power generation systems.

Wind power is a power generation method that uses the power of the wind to turn a generator to produce electrical energy. A variety of wind power generators have been developed and are being used to produce electricity, from micro-sized tens of watts to super-large with millions of watts.

Since the 1990s, it has developed rapidly in Denmark and Germany, and is rapidly spreading around the world. Small ones are also installed on the roofs of buildings, but large ones are built on windy plains, hills and the sea.

Wind power generators are divided into horizontal axis generators and vertical axis generators according to the direction in which the rotating shaft of the blades is raised. Since vertical axis generators have low conversion efficiency, most wind turbines currently installed are horizontal axis generators. This generator has a blade and generator attached to the left and right of the horizontal axis. When the wind blows, the blades rotate, and this rotational force is converted into electrical energy by turning a generator through a shaft.

The amount of power generated by wind power is proportional to the cube of the wind strength. Since the wind becomes stronger as it rises higher from the surface of the earth, the amount of power generated increases as the height of the generator increases. If the wind is too strong due to a typhoon, etc., the blades rotate faster and damage to the generator may occur. In this case, the operation of the generator is stopped.

In windy places, wind power can produce electricity at a cost similar to that of thermal power. In addition, since it does not emit greenhouse gases that cause climate change, it has been widely distributed in Western Europe since the 1990s.

In the 2000s, it was rapidly distributed in the United States and China, and as of 2010, China and the United States surpassed Germany and Spain in Europe to become the world's first and second largest wind power generation countries. Although interest in wind power generation is high in Korea, it has not spread rapidly due to geographical, military, and administrative constraints.

On the other hand, as described above, although a wind power generator is widely used as a natural and eco-friendly power generation method, a typical wind power generator has substantially lower power generation efficiency due to structural limitations, and is subject to restrictions on installation locations.

Accordingly, in consideration of the installation location, it is sometimes installed on the sea as shown in FIG. 1 , but in order to produce electricity using the structure as shown in FIG. 1 , the scale must be huge, so that the construction or installation cost is inevitably increased.

In addition, when considering that the conventional system including FIG. 1 is difficult to produce electricity because the blades do not rotate when there is no wind, considering that the efficiency may be reduced compared to the cost of construction or installation, this There is a need to develop technology to complement it.
