Can domestic wind turbines prop up wind power prosperity?

The development of thermal power is limited. Power generation companies have joined the wind power industry. It seems that the booming wind power industry can really flourish.

The development of clean energy must first be supported by technology and equipment. The development of the closely related industrial chain is the key to the prosperity of the wind power industry.

The bottleneck is still

Energy saving and emission reduction and ecological environmental protection have always been the hot issues of the society, and have also become the focus of attention of the “two sessions” in 2009. In his government work report, Premier Wen Jiabao emphasized that efforts should be made to strengthen energy conservation, emission reduction and ecological environmental protection efforts, including the development of a recycling economy and the active development of clean energy such as nuclear power, wind power, and solar power. Clean energy includes renewable energy sources such as hydropower, wind power, solar energy, bioenergy (biogas), and tidal energy. As its name suggests, renewable energy does not have the potential for energy depletion. In recent years, China’s clean energy, especially wind power, has indeed achieved rapid development. According to the "2008 National Electric Power Industry Statistics Express" released by the China Electricity Council, in 2008, the installed capacity of wind power has reached 12 million kilowatts, which has doubled in three consecutive years and achieved the 2010 target in advance. It is expected that 20 million kilowatts will be reached in 2010. In 2008, wind power infrastructure investment increased by 88.10%, wind power generation was 12.8 billion kilowatts, an increase of 126.79%. In fact, not only domestic, clean energy with wind power and nuclear power as the leader will become the largest precision turntable bearing in the production of tile shafts in the world. Manufacturing hot spots. It is reported that global clean energy investment has increased from 30 billion U.S. dollars in 2004 to 155 billion U.S. dollars in 2008. As we all know, in the situation where traditional fossil energy is scarce and environmental protection issues are becoming more and more prominent, clean energy has the advantages of not only meeting human energy needs but also having environmental protection and changing the entire economic development mode. In this context, wind power should be transported. And students.

However, there is still a long way to go for energy saving and emission reduction and ecological environmental protection. There are still many restrictive factors in the development of clean energy such as nuclear power, wind power, and solar power. Among them, the lack of independent core technologies has always been the bottleneck of the development of clean energy, and the development of wind power industry. Of course it is no exception. As the purchase order cost of wind turbine equipment accounts for about 75% of the development and construction cost of the entire wind power market, the localization of wind turbines is the key to reduce the one-time investment in wind power and is the key to the economic operation of wind turbines. It is also a breakthrough point for the development of wind power. At present, the localization rate of wind power equipment manufacturing in China is only 53%, and quality efficiency is really unsatisfactory. Naturally, it cannot adapt to the development of the wind power industry, resulting in a cost of up to 8,000 to 10,000 yuan per kilowatt of wind power equipment, and the maintenance cost remains high. Wind power operators can only “lose money to earn money” if they can achieve the main components of wind turbines, such as gearboxes, generators, and blades, all achieve localized mass production. The cost per kilowatt of wind power equipment is reduced to 4,000 yuan to 5,000 yuan. Yuan, then wind power has the strength to compete with coal power, of course, wind power development is even more powerful.

Breaking the topic localization

In late February of this year, the National Energy Administration held a seminar on wind power technology and equipment in Dalian, Liaoning Province. Zhang Guobao, deputy director of the National Development and Reform Commission and director of the National Energy Administration, pointed out at the meeting that if we want to change the energy structure, actively develop renewable energy such as wind power, and continuously increase the proportion of clean energy in China’s primary energy consumption, we must increase independent innovation. We will work hard to break through the bottleneck that restricts the development of the wind power industry and occupy the commanding height of the development of a new round of energy industry. Zhang Guobao also pointed out that the localization rate of wind power equipment is low, and it is still unable to adapt to the development of the wind power industry. The technical level of key equipment such as inverters and wind power bearings needs to be improved. To solve these problems, related companies can not be satisfied with the purchase of foreign drawings and simple imitation, but on the basis of digestion and absorption continue to achieve new innovation, launch new products. At this symposium, it was noticed that Dalian City announced plans to build China's largest wind power equipment production base. At present, Dalian has become one of the national megawatt-class wind power main equipment production bases. It has basically formed a 1.5 megawatt machine system integration as a leader to increase speed, motors, bearings, electronic control equipment, hubs, and mainframes. Such as supporting the wind power equipment manufacturing industry chain. The newly formulated wind power industry plan in Dalian is to form a 100 billion yuan industrial chain and build Dalian into the largest wind power equipment production base in China. In the Dalian wind power industry chain, Wafangdian Bearing Group Co., Ltd. (hereinafter referred to as "Watz axis") has publicized its flag and proposed to build the world's largest wind power bearing manufacturing base. Wind power bearing is one of the important supporting equipment for wind turbines. Due to the complex force and vibration of the wind power bearing, it must bear a large impact load, and the installation cost of yaw and pitch bearing is large, and it needs to reach the same life as the host for at least 20 years, while the domestic wind power bearing is in a long one. In this phase, it relies on foreign imports, which is expensive and increases the cost per kilowatt of wind power equipment. In recent years, the ZW axis has been aimed at the world level and has been market-oriented in order to revitalize the high-end supporting bearings in 16 key areas of the equipment manufacturing industry. It has implemented technological transformation with strong input, high level, and rapid output, and has now formed 1.5 trillion domestically. The all-round mass production capacity of watts, 2.1 MW, and 3 MW wind power bearings fully meets the advanced level of internationally imported wind power bearings.
