How to make wind turbines in line with China's national conditions

"Wind electric" appearance is not accidental. From the supply side, wind power equipment, assembly of low-skilled threshold and up to 30% of the excess profits rate is driving the influx of large number of state-owned and private enterprises the key factor, which is almost 90 years since warlords and crazy story on the production lines of pirated VCD ; from the demand side, the existing power enterprises of non-rational impulse to invest, but also local governments to pursue political achievements of the intrinsic motivation.

But in terms of energy security throughout the country, to develop wind power in itself is not a bad thing, because it can not only ease the situation of China¡¯s energy shortage; more importantly, clean energy future, the key to crack China¡¯s energy dilemma. Nuclear power is one of the options, of course, but by no means the only option, because of its raw materials and oil, could not escape from the long term dependence on imports, be controlled by others situation.

Wind power generator for the first time since 1986 entering the country has been little interest. Because nothing is, and solar energy, biomass and other new energy sources, like wind power in terms of cost and market price of coal on the loss - when people have not yet considered to be also the environmental cost of the habit, if the post-treatment costs into account, the coal is actually not really cheap. In recent years, as global warming and carbon emissions and other environmental problems have attracted worldwide attention, particularly in the central introduction of a "Renewable Energy Law" and the relevant financial supporting measures, the investment scale of China¡¯s wind power is significantly accelerated.

But even so, wind power generation currently accounts for the proportion of China¡¯s total generating capacity of less than 0.5%, said that China is still at the initial stage of wind power by no means an exaggeration. By the end of 2009, China¡¯s wind power installed capacity has reached 20 million kilowatts of energy, the scale ranks third in the world, behind the United States and Germany. Since even the land area of 23 Chinese provinces, but the German is not too large "surplus", then the Chinese wind power industry, from the "excess" premature.

In fact, the public letter to the Department has been talking about wind power industry, "excess capacity", the first layer of meaning refers to the wind turbines equipment manufacturing enterprises serious than the actual annual supply of wind power installed capacity; and deeper levels of meaning refers to a lack of self - intellectual property behind the wind power machine equipment overcapacity. At present, China 80 family traditions of electrical equipment manufacturing enterprises in more than 90% comes from a higher price from abroad for processing and assembly drawings follow suit.

Based on these "Exotic" drawings imitation of wind power equipment, as the Miao Minister said, is mainly based on Europe and the United States offshore conditions in China¡¯s southeast coast may also not a big problem, one to the inland water and land hard on the clothes, and can only be reduced to the wind electric field to act as the landscape, "flowers." Therefore, when running at full capacity most of the wind power companies do not suitable for China¡¯s inland areas to use wind power equipment, thus inevitably the overcapacity.

The problem is that just encompassed the five northwestern provinces and autonomous regions of the country¡¯s most abundant wind energy. Thus, for China¡¯s wind power industry development prospects also view: we must see the moment the facts behind the technology re-introduction, but also China¡¯s wind power industry¡¯s future. According to the author knowledge, some with their own domestic R & D capability of wind power equipment manufacturers have been increasing through the protective cover to solve the sand area of wind generators equipment, and short life span of the problems; while those who rely solely on drawings to buy foreign companies, but subject to foreign "shall not be altered arbitrarily drawing design" of the additional terms, which can not be matched by improvements.

As for the power enterprises blindly launched the phenomenon of wind farms, but also not "incurable" Yinyefeisi more is not necessary. Development and Reform Commission, Ministry of Public letter to the competent departments and other energy sources should be based on the actual situation in different regions to develop technical standards to improve the wind turbines equipment bidding threshold. If the foreign equipment manufacturer disdain for the Chinese domestic market to re-tailor the design of wind power equipment, then I¡¯m sorry, it can only make a market with independent intellectual property rights of domestic equipment manufacturing enterprises to share.

In contrast, to let local governments learn to "know one¡¯s place" down the more difficult - in order to dispel their engaging in "image projects" inertia, it will have on the current system for appointing officials to conduct in-depth assessment and reform, which is obviously not a simple technical problems.
