China's wind power equipment shuffling can not bypass

World Wind Power Network reports: Although the development of the wind power industry in China is not long, the problems exposed have caught the attention of the competent authorities.

Recently, 10 ministries and commissions, including the Ministry of Industry and Information Technology, jointly issued the article “Suppression of overcapacity and redundant construction in some industries, and guide the healthy development of the industry” (hereinafter referred to as “new document”), identifying six major industries such as wind power equipment and polysilicon as the next Step by step to curb the focus of macroeconomic regulation and policy guidance.

As a clean and renewable energy source, wind energy has been increasingly valued by countries around the world in the increasingly scarce conditions of the Earth's energy.

What is the current situation of China's wind power industry? How should wind power companies develop in the future? The reporter conducted an in-depth interview.

Potential oversupply in excess of development There is data showing that in September 2007 China released the "Mid-term and long-term development plan for renewable energy," it is proposed that by 2020, the total installed capacity of wind power is 30 million KW. By the end of 2008, there have been 11,638 wind turbines installed in China and the installed capacity has reached 12.17 million KW.

To this end, the competent authority revised the data and increased the installed capacity of the power supply in 2020 to 100 million KW. It is against this background that many countries in China have formed wind power investments that are rushing to the top, repeated introductions, and redundant construction. Industrial development has gradually evolved into overheating.

"The introduction of new documents is very timely and very necessary. China's wind power industry is not fully prepared before the development of the industry base is not solid, the management level is also very low, resulting in low efficiency, on the one hand is the repeated introduction of excessive construction of wind power equipment; On the other hand, most wind power plants continue to suffer losses, and such development will be a great waste of resources.” Zhu Junsheng, director of the Renewable Energy Professional Committee of the China Resources Resources Association, objectively evaluated the current situation in China during an interview with reporters. Wind power industry development status.

“But what we should pay attention to is that the new document is aimed at the level of equipment manufacturing, not for the entire wind power industry, and the regulation is not a limitation, but it should start with macro-control and policy guidance to ensure the future healthy development of the wind power industry. Zhu Junsheng said.

According to statistics, at present, there are more than 80 wind power plant manufacturers in China, and there are 50 blade plants and more than 100 tower manufacturing plants. Shi Pengfei, deputy director of the Wind Energy Professional Committee of the Chinese Renewable Energy Society, calculated the amount for the reporter. If the calculation is based on the power generation capacity of 500,000 KW per unit, the power generation scale will reach 40 million KW. However, the market capacity in China is less than 1/100. 4. From the data of last year, China’s wind power generation achieved 12 million KW in 2008, but it only accounts for 1.5% of the country's electricity, and the actual electricity consumption of the grid is only 0.3%.

“Although the current surplus is only a potential surplus, I think it is a good thing for the 10 ministries and commissions to issue new documents. On the one hand, China’s wind power industry has been developing since 2003, and although it’s not long but the development rate is very rapid, the new document focuses on To improve the quality and variety of products, on the other hand, early detection of development problems can be resolved early. From the perspective of mastering core technologies and the development of global cooperation, it is clear that China’s wind power industry needs to make up for many deficiencies,” Shi Pengfei told reporters.

It is not difficult to find a careful analysis of the new market into future development priorities. The new document focuses on regulating the future development of the wind energy industry. For example, the document stipulates that, in principle, no new approvals for the construction of a complete machine factory shall be approved or put on record, and it is forbidden to set up requirements for investors to use local wind power equipment in wind power project bidding and invest in the construction of wind power equipment manufacturing projects locally; establish and improve wind power equipment standards, The product testing and certification system prohibits backward technology products and non-entry product products from entering the market. There is no doubt that this will trigger the biggest change in the wind power industry since 2003.

A person in the industry who asked not to be named told reporters that the current domestic wind power equipment market is still in the early stages of development. The level of technology and quality of the products are uneven. Compared with international wind power giants such as Vestas, GE, etc. Big gap. If the document is strictly enforced, 40% of domestic production capacity will be eliminated.

Li Junfeng, secretary general of the Renewable Energy Professional Committee of the China Resources Utilization Association, said in an interview with reporters that the introduction of new documents will undoubtedly bring about reorganization and reshuffling of the industry, and those enterprises that do not possess core technologies and do not possess competitive advantages. Will be eliminated. The future wind energy industry will gradually realize the wide application of new technologies and new materials. Under the direction of the market, it will open up new application fields and open up international markets, which will become the direction of the company's efforts.

Fortunately, many domestic wind power equipment companies have already begun this attempt. Han Junliang, president of Sinovel Wind Power Technology Co., Ltd., said in an interview with reporters that the large-scale development of wind turbines is an inevitable direction of development, while the development of the wind power industry from land to sea is a major trend. After solving the technical and operational reliability, the Wind power will open up new markets. Just last month, China’s first batch of three domestically produced 3 MW offshore wind turbines independently developed by Sinovel Wind Power were successfully put into operation at the Shanghai Donghai Bridge’s 100,000 KW offshore wind farm, indicating that the technical level of offshore wind turbines in China is already in place. Global leadership.

Shi Pengfei also further pointed out that after the wind power manufacturing enterprises meet the domestic demand in the first step, the second step is to study the international situation, adapt to the rules of the game in different markets, and export the fan equipment to Europe, America, Southeast Asia, and Africa. Open up new battlefields for China's fan products.

As the vanguard of China's wind turbine industry, Xinjiang Goldwind Technology passed a 70% stake in Germany's VENSYS energy in 2008, and has taken a key step towards internationalization of technology. In the same year, it achieved a breakthrough of “zero” in overseas sales. Guo Jian, general manager of the company, said in an interview with reporters that in the future the global new wind power installation will still be mainly concentrated in Europe and North America, so the above-mentioned international market development has become a new strategic goal of Goldwind.

Han Junliang also told reporters that Sinovel’s future plan is to increase international revenues to more than 30% of the company’s total sales. At present, they are preparing to establish European and North American centers.

Strengthen the foundation should be hard work inside a wind power expert told reporters that the wind power industry is a new industry, through the introduction, digestion and absorption, the development time can be shortened, but the development process is impossible to leap, but also need to return to the basic aspects of industrial development . The promotion of wind power generation applications and the enhancement of competitiveness of wind power equipment manufacturers need to strengthen the research and development of new technologies. Compared with Western developed countries, there is still a big gap between China's power grid construction and the quality of wind turbines and components. Hefei Sunlight Power Co., Ltd. general manager, director of the China Renewable Energy Society Cao Renxian told reporters that the advantage of wind power is clean, non-polluting, its inadequacies in that it is a random energy, and its inherent instability will be on the grid The inconvenience of scheduling and management. For wind power generation, supporting forecasting measures and energy storage devices are also needed. Peak capacity adjustment is required and the entire power grid needs to be intelligent. In addition, the development of wind power in China is also facing a special difficulty, that is, China's wind resources are mostly concentrated in the western and northern regions, and power load centers are mainly in the southeast coastal areas, which also put forward higher requirements for power grid construction.

In addition, the quality of wind turbines and components also needs to be addressed through further technical research and development. “Overseas large-scale wind power development has a history of more than 30 years, and the wind power equipment used has undergone long-term, multi-faceted inspections, debugging and corrections. In recent years, China has only started the design and production of wind turbines through the introduction of technology, and the development speed of wind power has been accelerated. It also led to the blind expansion of some enterprises, there is not enough time for the equipment inspection and debugging.” Qin Haiyan, secretary general of the Wind Energy Professional Committee of the Chinese Renewable Energy Society, said in an interview: “At present, the generator set installed in China has not been in operation for a long time. It is not yet the high-quality period of mechanical equipment failure, but the existing data show that the key components such as spindles, bearings, gearboxes, and motors of domestically-manufactured domestically-manufactured units have repeatedly experienced quality and technical failures. In the year, the quality risks may be fully manifested."

Jiang Haifeng, chairman of Chongqing Gearbox Co., Ltd., believes that compared with wind power generators, the problem faced by wind power components is not overcapacity, but the development of parts and components industry can not keep up with the development speed of wind turbines. Key components also need to rely on imports. Jiang Haifeng said that China's wind power component companies should increase research and development efforts, improve product quality, and establish an influential brand image.

“From a technical point of view, the access threshold for wind power generation is relatively high, and it requires a profound accumulation at the technology and industry levels.” Zhang Lihui, partner of Qingyun Venture Capital, said in an interview with reporters, “Chinese companies are introducing technology at the same time. It should also be learned to digest and absorb these imported technologies. It is not enough to just 'shape' it, but it must also be 'really' to ensure the quality of the product and the stability of its operation."
