Guoneng Wind Power Masters the Core Technology of Megawatt Vertical Shaft Blower

“Using the vertical axis, power generation can be started at a wind speed of 1.8 m/s; using a conventional horizontal axis requires 4 m/s. This undoubtedly broadens the scope of use of wind power.” May 27, 2010, Xu Jin Quan said in the Zhongguancun exhibition area of ​​the 13th China Beijing International Science and Technology Industry Expo that “The vertical axis data does not exceed 15 dB compared with the noise of 75 dB in traditional wind power systems.”

From the professor of Shanghai Jiaotong University to the chief designer of Guoneng Wind Power Company, Xu Jinquan felt “difficulty in the industrialization of scientific and technological achievements”, and at the same time he identified “the vertical axis will be the development direction of future wind power generation” and “the cost is only The original 1/3-1/2, more stable power generation and higher reliability."

At present, China vigorously promotes the development of the new energy industry and regards it as a major strategic measure for adjusting energy strategies, transforming development methods, and promoting sustainable economic and social development. However, China's new energy technology base is relatively weak and the overall level is not high. Wind power, solar power and other core technologies and some key components are mainly dependent on imports.

To achieve rapid and healthy development of the new energy industry, we must vigorously carry out technological innovation and achieve breakthroughs in core technologies. The 1MW vertical axis wind power generation system developed by Guoneng Wind Power with independent intellectual property rights can reduce the investment per unit of kilowatts by about 50% compared with the conventional horizontal axis wind turbines, and can continue to be stable after the wind speed exceeds the rated wind speed. The output power. The vertical axis wind generator has the advantages of easy maintenance, simple blade design and manufacturing, low cost, and no need for wind devices.

Xu Jinquan introduced that, compared with the traditional horizontal-axis wind power system, the vertical axis wind power system has a higher utilization rate of the wind field, which can be up to 5 times higher than the traditional system. The vertical axis wind power system has the advantages of no noise and no cut-out. The inefficiency mode of the traditional system, “the wind turns to the hour and the wind stops,” avoids the impact of the current on and off the grid.

Guoneng Wind Power has mastered the core technology for the development of megawatt-class vertical axis fans, which will accelerate the upgrading of China's wind power industry and enhance China's international competitiveness in the field of new energy. State Grid Corporation of China decided to make full use of the advantages of the China Electric Power Research Institute and jointly develop a large vertical axis fan with Guoneng Wind Power. China Electric Power Research Institute has signed an agreement with the shareholders of Guoneng Wind Power Co., Ltd. and established a wind power equipment research and development center with Guoneng Wind Power Co., Ltd. to jointly promote the development and industrialization of large-scale vertical axis wind turbines.

The deputy mayor of Beijing, Mr. Lou Zhongwen, believes that Guoneng Wind Power Co., Ltd. promotes its own development through technological innovation, which is conducive to driving Beijing's green energy industry to become stronger and bigger, and promote the economic and social development of Beijing.

According to the forecast of the International Energy Agency, the total installed capacity of wind power in the world will reach 1.26 billion kilowatts by 2020, and the total annual power generation will account for 12% of the total global power generation in 2020. In recent years, the wind power equipment manufacturing market has developed rapidly. The annual production value is about 60 billion yuan. At present, the 1MW vertical axis wind power system has been established in Pinggu, Beijing.
