Example Embodiment

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 As shown, the present invention includes a tower column 2 that is perpendicular to the ground, and the bottom of the tower column 2 is connected to the ground through a support 1 . Two groups of power generation modules are arranged from top to bottom on the tower column 2, wherein each group of power generation modules includes a pair of wind wheel sets 4 arranged up and down, the upper wind wheel set 4-1 and the lower wind wheel set 4-2. A generator 7 is provided between. One of the wind wheel sets 4 includes a wind wheel hub 5 mounted on the tower column 2 , and also includes a plurality of main blades 10 that are evenly mounted on the wind wheel hub 5 through support rods in the circumferential direction. The wind wheel hub of the upper wind wheel set 4-1 is connected with the rotor 3 of the generator 7, and the wind wheel hub...

Abstract

The invention discloses a vertical shaft multi-state dual-blade bidirectional rotation wind driven power generation device which comprises a tower column, wherein an even number of wind wheels are arranged on the tower column; two wind wheels form a group, and a power generation module consisting of a power generator is arranged between the two wind wheels in one group; each wind wheel comprises a wind wheel hub arranged on the tower column and plurality of main blades circumferentially and uniformly arranged on the wind wheel hub through a supporting rod; in each power generation module, the wind wheel hub of one wind wheel is connected with a power generator rotor, and the wind wheel hub of the other wind wheel is connected with a power generator stator; an auxiliary blade is arranged on one side of each main blade; and the auxiliary blades are connected with wind wheel hubs through auxiliary blade angle adjustment rods. Each power generator body and each stator which are integrated rotate around each rotor along opposite directions. Therefore, the rotating speed of each power generator is high, so that the output efficiency is high, and the power generation amount of the unit volume of each wind wheel is increased.

Description

[0001] technical field [0002] The invention relates to a wind power generating device and its power generation control method. Background technique [0003] At present, in the field of wind power generation, the more commonly used generators are horizontal axis wind generators and vertical axis wind generators. The horizontal axis wind turbine is greatly affected by the wind direction. When the wind direction changes, the rudder needs to be used to adjust the windward direction of the wind power generation system. Its mechanical structure is complex and the energy loss is large during the turning process of the wind rotor. [0004] Vertical axis wind turbines are less affected by changes in wind direction and have a higher utilization rate of wind energy. However, in the vertical axis wind power generation device in the prior art, only one generator can be used for a group of wind rotors, and the power generation per unit volume is relatively small. In addition, the bl...
