Three-dimensional space dense layout vertical axis high-power wind turbine system

Abstract

The invention provides a three-dimensional space dense layout vertical axis high-power wind turbine system which comprises a cylindrical wind gathering tower, wherein the wind gathering tower is arranged in a perpendicular manner; a plurality of layers of platforms are arranged in the wind gathering tower in the perpendicular direction; a plurality of stages of wind generating sets are arranged on each layer of the platform in the radius direction from inside to outside; an annular air passage is arranged on the periphery of each stage of the wind generating set; the annular air passages in the same radius direction are connected in a penetrating manner; a windward hole is formed in the outer vertical face of the cylindrical wind gathering tower and communicates with the annular air passage on the outermost side through a tapered bell-mouth shaped air passage to form a group of communicated air passages. The wind gathering tower is hollow, and two groups of air passages in the same diameter direction communicate with each other. Due to the funnelling effect, wind enters the wind turbine system from the windward hole, the wind power is greater when the wind enters the wind turbine system gradually, and wind can enter the other group of air passages in the same diameter direction from one group of air passage to utilize wind energy to the maximum. The three-dimensional space dense layout vertical axis high-power wind turbine system is high in installed capacity and generating efficiency, small in occupied area, long in service life, and wide in application prospect.

Description

technical field [0001] The invention relates to a high-power wind power generation system with a vertical axis and a three-dimensional dense layout, belonging to the technical field of wind power generation. Background technique [0002] A wind power generation system is a technology that converts wind power into rotational force to generate electricity, and is a system that converts wind energy into mechanical energy and drives a generator to generate electricity. According to the State Grid of China, the global clean energy market has a market share of 50 trillion US dollars. [0003] Wind power generation systems are generally divided into horizontal axis wind power generation and vertical axis wind power generation. Horizontal axis wind power generation has high efficiency, but it is greatly affected by wind direction; vertical axis wind power generation is not greatly affected by wind direction, but its efficiency is not high compared with horizontal axis wind power ge...
