The windward power generation area includes a wind power generation unit. With the wind power generation system of the invention, the wind power generation unit can be replaced or maintained easily if the wind power generation unit breaks down, and thus the invention can reduce the maintenance cost and manpower and enhance the efficiency of using green energy.

## Background
FIELD OF THE INVENTION
The present invention relates to a wind power generation system, and more particularly to a management system for managing a group of wind power generation units and capable of replacing or maintaining the wind power generation units easily.
BACKGROUND OF THE INVENTION
As new developing countries rise, there are increasingly more middle-class people who pursue a better quality of life and consume lots of power, and such a huge consumption leads to an increasingly higher demand of energy, and thus the price of oil rises rapidly, and the environmental pollution becomes a serious issue. Obviously, developing and applying a new clean and green energy demands immediate attentions and feasible solutions.
In present conventional green energy sources such as solar power generation systems, wind power generation systems and even tidal power generation systems, all green energy sources other than the wind power generation system are still at the stage of improving the efficiency of generating power or at a theoretical stage. The conventional wind power generation systems are generally large systems installed in an open area. For example, a large wind power generation system is installed along a seashore. However, if such large-sized wind power generation system breaks down, the maintenance cost is very high, and more importantly, the maintenance process is very troublesome and even requires a super-large hoist for removing and reinstalling the system after the maintenance is made. It is pity, but yet common to see abandoned governmental large wind power generation systems, and such outcome is definitely not the original intention of protecting environment. Furthermore, tremendous governmental expenditures are wasted.
Therefore, it is an important subject for this invention to develop a wind power generation system capable of replacing, maintaining or repairing the wind power generation units easily to reduce maintenance cost, time and effort, so as to improve the application and efficiency of green energy.
SUMMARY OF THE INVENTION
In view of the shortcomings of the conventional wind power generation systems, the inventor of the present invention based on years of experience to conduct extensive researches and experiments, and finally developed a wind power generation system in accordance with the present invention to overcome the shortcomings of the prior art.
Therefore, the primary objective of the present invention is to provide a wind power generation system, in hope of achieving the effects of reducing maintenance cost, time and effort as well as improving the application and efficiency of green energy.
To achieve the foregoing objective, the present invention provides a wind power generation system comprising: at least one windward power generation area, being a hollow structure, and having a wind power generation unit; at least one maintenance and repair area, for maintaining and repairing the wind power generation unit; a transmission system, connected to the windward power generation area and the maintenance and repair area, for conveying the wind power generation unit; and an auto-management system, for managing the windward power generation area, the maintenance and repair area and the transmission system.
The wind power generation system definitely can achieve the effects of reducing maintenance cost, time and effort as well as improving the application and efficiency of green energy.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic view of a wind power generation system in accordance with the present invention;
FIG. 2A is a perspective view of a horizontal-axis wind power generation unit in accordance with the present invention; and
FIG. 2B is a perspective view of a vertical-axis wind power generation unit in accordance with the present invention.



DESCRIPTION OF THE PREFERRED EMBODIMENT
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings.
With reference to FIG. 1 for a wind power generation system in accordance with the present invention, the system comprises at least one windward power generation area 10, at least one maintenance and repair area 20, a transmission system 30 and an auto-management system 40. The windward power generation area 10 is a hollow structure for allowing wind to flow smoothly without turbulence, and comes with dimensions of 3 m×3 m×3.5 m (Length, Width, and Height). The windward power generation area 10 includes a wind power generation unit 12 which is a horizontal-axis wind power generation unit (as shown in FIG. 2A) or a vertical-axis wind power generation unit (as shown in FIG. 2B). The maintenance and repair area 20 is provided for maintaining and repairing the wind power generation unit 12 and can be disposed at any position of the wind power generation system. Taking the intensity of wind into consideration, we generally set the maintenance and repair area 20 at a weak wind position, preferably a position near the ground, in order to use the wind effectively. The transmission system 30 is also a hollow structure that will affect the direction of wind to produce turbulence. The transmission system 30 is connected to the windward power generation area 10 and the maintenance and repair area 20 for conveying a damaged wind power generation unit 12 from the windward power generation area 10 to the maintenance and repair area 20, and then conveying the repaired wind power generation unit 12 from the maintenance and repair area 20 back to the windward power generation area 10. The auto-management system 40 is provided for managing the windward power generation area 10, the maintenance and repair area 20 and the transmission system 30. In a preferred embodiment of the invention, the windward power generation area 10 includes a power generation detector, such that if the power generation detector detects a low power generation of the windward power generation area 10, the situation of low power generation will be reported to the auto-management system 40, and the auto-management system 40 will issue a command to the wind power generation unit 12 installed in the windward power generation area 10 and transmit the command from the transmission system 30 to the maintenance and repair area 20 for performance the maintenance and repair, and then the repaired wind power generation unit 12 will be conveyed from the maintenance and repair area 20 back to the windward power generation area 10.
In summation of the description above, the invention overcomes the shortcomings of the prior art by installing at least one windward power generation area, at least one maintenance and repair area, a transmission system and an auto-management system, such that when the wind power generation unit breaks down, the wind power generation unit can be replaced or repaired easily to reduce maintenance cost, time and effort, so as to improve the application and efficiency of green energy. The invention complies with the patent application requirements, and thus is duly filed for patent application.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
