Description

technical field

[0001] The invention relates to a multi-layer stacked combined wind power generation system in the technical field of wind power generation. Specifically, it relates to a novel vertical wind power generation system with multiple layers of wind power machines superimposed and combined. Background technique

[0002] With the occurrence of the world energy crisis, the use of wind kinetic energy as a new energy source has become a hot spot in the development of modern society. The generator set and speed increaser of the traditional three-blade wind turbine are installed at a height of 70 meters to 120 meters above the top of the tower, and the long and heavy wind blades are hung obliquely on the side, and a large counterweight is required. Considering that the wind blades, speed increaser, generator set, counterweight and the heavy engine room have a weight of hundreds of tons, which are supported at high altitude by the tower, the wind blowing will generate a ...
