Liftable wind power generation device capable of achieving high-altitude automatic adjusting and keeping of relative position

Abstract

The invention relates to a high-altitude wind power generation device in the field of wind power generation. The wind power generation device comprises three parts including a high-altitude suspensiondevice, a traction cable and a ground recycling system. The high-altitude suspension device is a kite with multiple rotors, the high-altitude suspension device can be lifted up and down through the multiple rotors, and the multiple rotors can generate electricity. In the process of power generation at the high altitude, wind power can be generated by a sail, empennage windward area adjusting andswitching of the multiple rotors from the power generating state to the power consumption state to maintain the relative position of the suspension device at the high altitude, so that the high-altitude suspension device conducts suspension power generation within a certain space range. During multi-unit cluster distributed power generation, the high-altitude space utilization rate is improved, and it is ensured that the problems of position interference and cable entanglement cannot be caused when all units operate in coordination. In the manner, wind power generation is not limited by regions, and large-scale application can be achieved.

Description

Technical field [0001] The invention belongs to a high-altitude wind power generation device in the technical field of wind power generation. Background technique [0002] The global energy structure is dominated by fossil energy, a one-time consumption of non-renewable energy, which brings about global warming, smog and other environmental problems. Other renewable clean energy sources such as solar energy and wind energy have not been widely used, mainly because of high input-output ratio and poor economic efficiency. [0003] The total global wind energy reserves are large and the utilization rate is low. The current wind power plant is mainly an iron tower supporting the wind wheel structure. This structure has a limited installation height and can only obtain low-altitude and low-energy density wind energy within about 100 meters on the ground. Moreover, it can only be built in areas with high wind energy density, and coastal areas can only be built in shallow sea areas, so ...
