Wind power starts again, and the collective needs to make up a missed lesson

the eagerly awaited 12th Five Year special plan for the development of wind power technology has recently been issued. It's time to calm down and make up classes collectively. The heartfelt sigh of a wind power enterprise executive also represents the views of most people in the industry. In 2011, China's newly installed wind power capacity was 17.6309 million KW, accounting for 43% of the world's newly installed capacity that year, and continued to maintain the global leading position. In the same year, frequent wind turbine accidents cast a shadow on this scenic industry. The problems exposed in the process of explosive growth, such as weak technological autonomy, imperfect public service systems such as wind power standards and testing, have forced China's wind power industry to adjust its pace and carry out reassembly

a smooth journey is hard won.

the rapid development of the wind power industry first benefits from the strong support of national policies. At the same time, the increasing awareness of independent innovation of China's wind power enterprises ensures the endogenous driving force of development

in late April, I came to Shaanxi Luneng Jingbian wind farm located in Jingbian County, Yulin City, Shaanxi Province. The scene of dozens of typhoons on the hillside rotating in the wind in the Loess sand fog is shocking. After the project is put into operation, it can provide 90million kwh of clean electric energy to electricity. Xiaoyaofeng, the head of the wind farm, said as he looked up at the fan

from the start of small-scale demonstration projects in the mid-1980s to now becoming the world's largest wind power country, China's wind power industry has been advancing by leaps and bounds. By the end of 2010, China had jointly built more than 800 wind farms, built the first 100MW offshore wind power project in Asia, more than 20 developers with large-scale wind farm construction capacity, and more than 20 enterprises with megawatt wind turbine mass production capacity

at the recent 6th China (Shanghai) International Wind Energy Exhibition and seminar, hedexin, chairman of the wind energy professional committee of the China Renewable Energy Society, said that Chinese enterprises accounted for four of the top 10 wind turbine manufacturers with new installed capacity in the world in 2011. In 2011, 12 Chinese enterprises' wind power equipment products entered the international market, and 5 enterprises developed wind farms abroad

the rapid development of wind power industry first benefits from the strong support of national policies. The renewable energy law of the people's Republic of China passed in 2005 has laid a solid foundation for the development of China's wind power industry by making the development and utilization of renewable energy a priority area of energy development, arranging funds to support relevant scientific and technological research and industrial development, and encouraging and supporting renewable energy and power generation. For another example, in 2009, the national development and Reform Commission issued the notice on improving the electricity price policy of wind power generation through RS232 port, which divided the country into four types of wind energy resource areas, and formulated the electricity price of wind power benchmark accordingly, which is conducive to promoting more diversified investors to participate in wind power operation

at the same time, the increasing awareness of independent innovation of China's wind power enterprises ensures the endogenous driving force of development. The 12th Five Year special plan for the development of wind power technology (hereinafter referred to as the "plan") points out that under the guidance of the 11th five year plan, domestic scientific research institutions and enterprises have mastered the industrialization technology of 1.5MW to 3.0MW wind turbines. The manufacturing capacity of domestic blades, gearboxes, generators and other components has approached the international advanced level, meeting the supporting needs of mainstream models, and began to export; The research and development of bearings, converters and control systems with high added value and high-tech content has also made significant progress and began to supply the domestic market

recently, the blade testing center of our company passed the static load test of 62 meter 5MW blade under the certification of GL, which is also the first 5MW blade in China to pass the GL certification. At the same time, Zhu Weixin, manager of the administrative department of Zhongfu Lianzhong Composite Materials Group Co., Ltd., also couldn't help sighing that this success has condensed the painstaking efforts of too many people

take the opportunity to rebuild internal skills

the comprehensive background of tighter national policy regulation, narrower market space and prominent technology gap has given China's wind power industry, which has been galloping for a long time, a breathing opportunity for adjustment

in August, 2011, the National Energy Administration issued 18 important technical standards urgently needed by the development of the wind power industry, such as the technical code for the design of large wind farms, covering many fields such as large wind farms, offshore wind power construction, and wind turbine condition monitoring, which further raised the technical threshold of the wind power industry. In the same year, the issuance of the Interim Measures for the management of wind power development and construction formally incorporated the approval of wind power into the national unified planning. The local governments that could have independently approved wind farms below 50000 kW could no longer easily approve wind power projects. In view of the frequent wind turbine accidents and the series of problems that occurred in the wind power industry, the national wind control measures effectively curbed the deviation trend of the wind power industry

at the same time, due to the expansion of industrial capacity and the slowdown of growth rate, 60% of the enterprises in the whole wind power industry chain experienced a profit decline in 2011. In this dilemma, many enterprises began to target overseas markets with great potential. But it's not easy to get out. China's wind power started late, and there is still a large gap compared with the international advanced level. Qihesheng, Secretary General of wind energy equipment branch of China Agricultural Machinery Industry Association, said

the plan points out these gaps: the independent design and innovation ability of advanced wind power equipment needs to be strengthened; Basic data such as wind resources are not perfect, and key technologies such as wind farm design, consolidation and operation need to be improved; The public testing system of wind power industry has just started, and the wind power standards, testing and certification system need to be further improved; The basic theoretical research of wind power needs to be deepened, and there is a lack of independent innovation; The discipline construction and talent training of wind power need to be strengthened urgently; The research and development of small and medium-sized wind turbines and the non parallel access technology of wind power need to be further improved

the comprehensive background of tighter national policy regulation, narrower market space and prominent technology gap gives China's wind power industry, which has been galloping for a long time, a chance to breathe and adjust. In this regard, hedexin suggested that China's wind power industry should improve its ability of independent innovation, control the manufacturing quality of wind power products, ensure the safe operation of the wind power industry, adopt diversified models to develop wind power, strengthen international exchanges and cooperation, and promote Chinese enterprises to go global

in addition to going out, moving to the sea has also become a strategic choice for many wind power enterprises. During the 11th Five Year Plan period, China has started the development of offshore wind power. The first offshore project, Shanghai Donghai Bridge Wind Farm, installed 34 domestic 3.0MW wind turbines, which were all realized and generated power in June 2010; In September, 2010, the National Energy Administration organized and completed the first round of bidding for offshore wind power concession projects, with a total capacity of 1million kW. Located in the coastal and intertidal areas of Jiangsu Province, it is about to enter the rapid development and large-scale development. Therefore, the offshore net profit of 28.3 billion days of power generation in the claw stage of the virus is bound to become the main battlefield of competition for wind power enterprises. This competitive platform with higher scientific and technological content will also put forward higher requirements for the innovation ability of China's wind power enterprises. To this end, many sensitive wind power enterprises have begun to take advantage of the opportunity of industrial adjustment to rebuild their innovation skills
