Hohai University, developed by the Chinese wind turbines achieved a major breakthrough in some key technologies with independent intellectual property rights of the 10 kW vertical axis wind turbine has already begun production, which will not only break a large number of core technologies and equipment imported from abroad situation, And our products will be exported to the European market.
Current domestic wind power machine manufacturing enterprises has reached more than 70, more than other parts of the world’s wind power 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 missing, become China’s wind power industry of the main obstacles. Therefore, the introduction of key technologies of wind generators basic research on China’s wind power development significance.
Hohai University, according to Professor Zheng Yuan, at present the 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 almost 100 meters altitude, the power exists yaw losses, which is high cost of domestic wind power one of the reasons. 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, to reduce noise pollution, and its wind energy utilization coefficient and the horizontal axis wind turbine fairly.
