PROBLEM TO BE SOLVED: To provide electricity twice as much as by a conventional system by one tower of a wind power generation system. SOLUTION: Whereas a conventional wind power generation system has one windmill, this system uses two windmills having the same diameter such as a reverse-rotation windmill on the front side and a normal-rotation windmill on the rear side (the front side can be interchanged with the rear side), and generates power twice as much as that of the conventional one by operating two generators. |
