Chinese wind turbine blindly "great" worthy of vigilance

“For the current trend of large-scale wind turbines in China, Li Junfeng, deputy director of the Energy Research Institute of the National Development and Reform Commission, expressed his concern. He said: “When the 1.5 MW and 2 MW wind turbines are not fully matured, some of our industry authorities are In the process of setting industry standards and bidding, we advocate the promotion of 3 MW and 5 MW turbines, and even use large MW fans as the technical threshold for industrial support policies. Such blatant greed for innovation is worthy of caution. ”

According to reports, China’s wind turbines have entered the “megawatt-scale era” since 2005. In 2009, megawatt-class wind turbines became the mainstream in the market. In 2010, 2.5 megawatt-class wind turbines became the industry support standard. Some officials of the Ministry of Science and Technology even declared to the media that during the “Twelfth Five-Year Plan” period, 3-5 megawatts of land-based wind turbines and 5-10 megawatts of offshore wind turbines should be pushed.

Li Junfeng told reporters that China's wind power equipment technicians have started to develop 1.5 MW fans in Europe since the mid-1990s. Until today, 1.5 MW wind turbines and below accounted for more than 85% of the local market, and more than 2 MW wind turbines. Only 10%. R epow er went offline from the first 5 MW fan in 2004, and it is still less than 10 5 MW wind turbines put into operation today. In China, in the bidding for major wind power projects such as Hami in Xinjiang, the direct Sword refers to large wind turbines with a capacity of 2.5 megawatts or more, and the number involved more than 1,000 wind turbines.

“Apart from individual large wind turbine manufacturers, how many of the country can build 5 MW fans? Even large wind turbine manufacturers can build more than 50 a year? Does one company manufacture 1.5 MW fans for more than 5 years?” Li Junfeng reminded us that the development of wind power in China cannot blindly pursue "big crews" but must pursue "high efficiency." Fan manufacturers can't win with big wins, but they must be strong.

When talking about the special investigation launched by the National Energy Administration on wind power quality issues recently, Li Junfeng believes that this is an important measure taken by the government departments to promote the healthy development of China's wind power industry. “However, the accident rate of more than 10 units a year is not high compared with the large-scale development of the wind power industry. Foreign countries have similar problems in the development of wind power.” He said, “China needs to pay high attention to the quality of wind power that currently appears. But don't worry."
