Three-dimensional space omni-directional energy collecting vertical-axis high-power wind power generation system

Abstract

The invention provides a three-dimensional space omni-directional energy collecting vertical-axis high-power wind power generation system which comprises a cylindrical wind collecting tower arranged vertically. A plurality of layers of platforms are arranged in the wind collecting tower in the vertical direction. A core unit is arranged in the center of each platform. Air ducts are arranged on the periphery of each core unit in the radial direction. A plurality of stages of wind generating sets are arranged in each air duct from inside to outside. Windward ports are formed in the outermost sides of the air ducts, namely the external wall of the cylindrical wind collecting tower. Each air duct is of spiral structure and shrinks gradually from outside to inside, and wind force becomes higher inwards after wind enters the air ducts through the windward ports due to the funneling effect, so that the installed capacity of the wind generating sets gradually increases towards the core area, and the installed capacity of the core unit in the center is the maximum. According to the three-dimensional space omni-directional energy collecting vertical-axis high-power wind power generation system, the installed capacity is large, the occupied area is small, the power generation efficiency is high, a combined wind power generation mode in which wind energy is utilized most efficiently, and the maximum single-set installed capacity, the maximum integration degree and the optical cost performance are achieved is achieved, and broad application prospects are achieved.

Description

technical field [0001] The invention relates to a three-dimensional omnidirectional energy-gathering vertical axis high-power wind power generation system, which belongs 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 wi...
