What is a Vertical Axis Wind Turbine?

The vertical axis wind turbine does not need to face the wind when the wind direction changes. Compared with the horizontal axis wind turbine, the vertical axis wind turbine has a great advantage. It not only simplifies the structural design, but also reduces the gyro force when the wind wheel is facing the wind.

Although there are many types of wind turbines, they can be divided into two categories:

Wind power, like solar power, was originally developed to address emergency power supplies and remote areas, so it was not developed very quickly at first.

In the 1920s and 1930s,

Wind power in emerging markets is developing rapidly. Under the background of national policy support and tight energy supply, China's wind power, especially wind power equipment manufacturing, has also risen rapidly, and has become the most active place for wind power in the world. In 2006, 9% of global wind power funds were invested in China, with a total of 1.62 billion euros (approximately 16.27 billion yuan). In 2007, China's installed wind power capacity ranked fifth in the world. As of 2010, China's wind power installed capacity has reached 42,287MW, ranking first in the world. ^[1]

In 2002, China took the lead in the research of new vertical axis wind turbines, led by the Ministry of Military Communications, with a Shanghai company as the research and development main body, and a team of experts from Xi'an Military Power, Xi'an Jiaotong University, Tongji University, and Fudan University cooperated in The first new vertical axis wind turbine was produced in just one year. And in less than 5 years, it has expanded its power to 200W 100KW, which is a world leader. Other countries in the world have also carried out research and development of new vertical axis wind turbines. Japan began research in early 2002, and products were put on the market in early 2003 with powers ranging from 0.5 to 30KW. The United States, the United Kingdom, Germany, Austria, South Korea and other countries have also produced prototypes in 2006, ready to be put into large-scale production, the power is less than 10KW. ^[2]
