Embodiment 1

[0043] Such as figure 2 It is a schematic structural diagram of the wind power generator system in Embodiment 1 of the present invention. A gyrotron with a length of 2,000 meters and a radius of gyration of 100 meters, other positions are straight lines, the length direction of the gyrotron is in the windward direction, the height of the gyrotron is designed to be 20 meters, the total length of the blades is 23 meters, and the width is 2 meters. The number of cars is about 250-350, as long as the power reaches nearly 40 megawatts when the wind direction is not parallel to the straight line and reaches 13 m / s.

[0044] image 3 It is a schematic diagram of the connecting structure of the blade and the trolley of the present invention. The blade in the figure is a whole. The blade is connected to the upper and lower rotating shafts 53 of the blade through the upper and lower blade handles 51, and then through the blade angle servo system 56 The control vane 55 rotates at a de...

Embodiment 2

[0054] Such as Figure 11 It is a schematic structural diagram of the vertical wind power generator system of Embodiment 2. In the picture, there is a polygonal gyroscopic body with a length of 2000 meters. The length direction of the gyroscopic body faces the wind. The height of the gyroscopic body is designed to be 20 meters. The total length of the blades is 23 meters, and the width is 2 meters. The number of trolleys is about 250-350. The power reaches nearly 40 megawatts as long as the wind direction is not parallel to the straight line direction and reaches 13 m / s. The device in Example 2 is the same as that in Example 1.

Embodiment 3

[0056] A circular gyratory body with a diameter of 2000 meters, the height of the gyratory body is designed to be 20 meters, the total length of the blades is 23 meters, and the system is 2 meters wide. The number of trolleys is about 400-450, and the wind speed reaches 13 meters per second. When and in any wind direction, the power reaches nearly 35 megawatts. The device in Example 3 is the same as that in Example 1.

Abstract

The invention relates to a wind turbine system and an electricity generation method of the wind turbine system. The wind turbine system comprises a convolution body surrounding a circle, a supporting part supporting the convolution body, a rail arranged on the convolution body, a plurality of connected trolleys, vanes connected with the trolleys, a plurality of generators fixed to the convolution body, a plurality of positioning devices installed on the convolution body and the trolleys respectively and used for sending and receiving signals, and electricity receiving devices which are installed on the trolleys and are capable of receiving power electricity, wherein the rotation angles of the vanes can be controlled to be adjusted, an automatic sailing driving instrument is arranged in each trolley, a wind indicator is installed at the top of each vane, the input end of each automatic sailing driving instrument is connected with the corresponding wind indicator, and the output end of each automatic sailing driving instrument is connected with a hydraulic servo mechanism. The wind turbine system can achieve industrial production and is designed in a modularized mode, the shape of the wind turbine system can be designed according to the landform of the installation site, and the wind turbine system is particularly suitable for a large wind turbine system.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to an industrially applicable large-scale wind power generation system and a power generation method thereof. Background technique [0002] In order to make better use of wind energy, people have designed various forms of wind power generation systems, classified from the structural form of the wind turbine rotation axis in space, mainly including horizontal axis wind turbines with the rotation axis arranged in the horizontal direction and the rotation axis A vertical axis wind turbine arranged in a vertical direction. [0003] The wind rotor of the existing vertical axis wind turbine adopts blades with a certain airfoil shape, such as figure 1 As shown, these blades are generally fixed on the cantilever that rotates around the center of rotation, and these blades are connected to the vertical shaft through the cantilever to form the wind rotor of the vertical axis wind turbine...
