Abstract: A wind power generation system is presented that includes a number of wind power generation units on the supporting tower, each wind power generation unit is formed by one vertical axis wind rotor and one or more power generation unit(s). The rotation shaft of the wind rotor is coupled with the rotor shaft of the single generator set through a connector, or the rotation shaft of the wind rotor is connected with the rotor shafts of multiple generator sets through a transmission mechanism. A helical vertical axis wind rotor and a lineal vertical axis wind rotor constructed by a drag type blade and a lift type blade is incorporated having a disassembling and splicing design. With this configuration, the number of the generator sets connected to the single wind rotor in the power generation unit may be adjusted in real time in accordance to different conditions.

Abstract: The present invention relates to a wind power generation system. Said system is an array of a number of wind power generation units on the supporting tower, each wind power generation unit is formed by one vertical axis wind rotor and one or more power generation unit(s), in which the rotation shaft of the wind rotor is coupled with the rotor shaft of the single generator set through a connector, or the rotation shaft of the wind rotor is connected with the rotor shafts of multiple generator sets through the transmission mechanism. The present invention proposes a helical vertical axis wind rotor and a lineal vertical axis wind rotor constructed by the drag type blade and the lift type blade, and proposes a helical wind rotor with pure drag type blade as well as the disassembling and splicing design of the above wind rotor. The present invention is similar to a “building block” power generation unit whose design could be optimized according to the wind field to reach megawatts scale power output.
