Description

Energy-saving power-assisted vertical axis wind power generation system

Technical Field

The utility model relates to a vertical axis wind power generation system.

Background

Wind power generation is one of clean energy sources, and is widely applied to the environment with more wind resources at present. The wind power generation equipment is structurally divided into: the wind power generation system comprises a horizontal axis wind power generation system with a rotating shaft of a wind wheel parallel to the wind direction, and a vertical axis wind power generation system with a rotating shaft of a wind wheel perpendicular to the ground or the direction of airflow. Horizontal axis wind power generation has been developed to 15 megawatts with tower heights in excess of 200 meters and impeller diameters in excess of 180 meters, which presents significant challenges to the design, installation, maintenance, and reliability of large wind power generation. On land, the increase of the power of the onshore wind turbine is limited due to the difficulty of transportation caused by the overlong blades; for an offshore wind turbine, under extreme weather conditions such as typhoon, irreversible damage can be caused to a high-rise wind tower and blades.

Because the vertical axis wind power generation system does not need to face the wind when the wind direction changes, the vertical axis wind power generation system is a great advantage in this respect compared with a horizontal axis wind power generation system, the vertical axis wind power generation system not only simplifies the structural design, but also reduces the gyroscopic force of the wind wheel when facing the wind. The vertical axis wind power generation system is divided into a resistance type and a lift type, the resistance type has low utilization rate of wind energy, and cannot be used for large-scale wind power generation. One reason that the conventional vertical axis high-power wind power generation system is not as popular as a horizontal axis fan is that the larger the power is, the larger the blade is, and the larger the weight of the blade is, the larger the cantilever beam structure is difficult to be. The efficiency of the existing vertical axis wind power generation system is relatively low.
