Chinese companies build the world’s first high-power vertical axis wind turbine

China's large state-owned enterprises have developed the world’s first 1 MW vertical axis wind power prototype with completely independent intellectual property rights and are currently conducting production prototype testing.

On April 26th, more than a dozen new projects and projects to be built including the Zhongguancun New Energy Industrial Park were unveiled at the 2011 China Merchants Press Conference in Pinggu Qiaokou Town, Beijing. This indicates that a green industrial town is quietly rising in the Pinggu District of Beijing, China, where the ten thousand mu of peach blossoms are competing. The reporter learned from the conference that the most important project in the Zhongguancun Guoneng New Energy Industrial Park is the construction of China's high-power vertical axis wind power equipment manufacturing base. Megawatt-class vertical axis wind power generation technology is the most advanced and advanced technology for the global use of wind energy.

Compared with the traditional “big windmill” horizontal-axis wind power generation technology, the vertical-axis wind turbine looks like a “Tibetan prayer wheel”. Although the volume is small, the advantages are obvious: First, the efficient use of the wind farm is only used. One-third of the area; Second, the power generation efficiency is as high as 85% compared with the level of more than 15 percentage points; Third, the structure is simple, light weight, easy maintenance; Fourth, wind resistance up to 50 meters / second, equivalent to anti-14 Grade wind; 5, the investment cost is reduced by about 30%; 6, the equipment has a long service life; 7. The noise pollution is low; 8. The raw materials of the manufacturing equipment can be recycled.

Xu Jinquan, chief engineer of Guoneng Wind Power Co., Ltd., is Professor of Mechanics at Shanghai Jiaotong University. He was employed by a central enterprise in 2010 and came to work in Beijing. On the morning of April 26, Xu Jinquan spoke remarkfully to reporters about the “attractiveness” of vertical-axis wind turbines: Because of the use of permanent magnet generators, a megawatt generator set can eliminate the need for an external power supply. Start, as long as the first wind speed can start generating electricity. According to the new magnetic levitation support theory, generators weighing up to 8 tons basically do not generate friction during operation, not only have high power generation efficiency, but also have low noise pollution. The entire unit runs quietly, only about 15 dB...

Jiang Dalong, chairman of Guoneng Wind Power Co., Ltd., revealed that the new wind turbine equipment manufacturing project plans to invest 1.5 billion yuan. After the project is put into production, it is estimated that the annual output value will reach 5 billion yuan.
