Wind power is the use of wind-driven windmill blades rotate, and then through the growth machine will increase the speed of rotation, to encourage generators. Wind power is in the world to form a craze for wind power without fuel problems, it does not produce radiation or air pollution.

Recently, developed by the Hohai University of China, wind turbines achieved a major breakthrough in some key technologies with independent intellectual property rights of 10kW vertical axis wind turbine has started production of wind turbines will not only break a large number of core technologies and equipment from abroad the introduction of the situation, and the Chinese products will be sold in the European market.

China’s wind power industry has developed rapidly, the current domestic wind generators machine manufacturing enterprises has reached more than 70, more than other parts of the world’s wind generator equipment manufacturers combined. However, the core technology and key components, the Chinese enterprises to go is to introduce line, the core technology and independent innovation capability deficiencies, resulting in high cost of wind power, becoming China’s wind power industry of the main obstacles. Therefore, the key technologies of wind turbines basic research on China’s wind power development significance.

Water Conservancy and Hydropower Engineering Hohai University, Associate Dean Professor Zheng Yuan said that the current large-scale wind turbines are horizontal axis wind turbine, the defect is designed to technically complex and weighing dozens of tons of the cabin to be installed in nearly 100 meters of altitude, There yaw power loss, etc., these are the domestic causes of the higher cost of wind power. The Hohai University, developed the vertical axis wind machines without the need for wind, there is no yaw power loss; blade design is simple, completely self-design; cabin and wheel gear box can be placed under the wind or on the ground, maintenance costs, lower; vertical axis wind turbine noise smaller than the horizontal axis wind turbines , to reduce noise pollution, and its wind energy utilization coefficient and the horizontal axis wind turbine fairly.
