The future development of wind turbines must focus on specialization and quality

The 6MW wind turbine prototype independently developed by Sinovel Wind Power will go offline in June this year, which will make China the second country after Germany to independently manufacture 6MW wind turbines. At the same time, another domestic wind turbine manufacturing giant Goldwind also plans to complete the design of the 6MW permanent-magnet direct-drive wind turbine unit and the detailed design of the components in 2011, and complete the first prototype installation by the end of June 2012.

Therefore, the “2010-2015 China Wind Power Industry Investment Analysis and Prospect Forecast Report” published by China Investment Advisors pointed out that the large scale of wind power equipment has always been considered as a major direction for the development of domestic wind power equipment industry in the future. In recent years, major domestic wind turbine manufacturing companies are accelerating the research and development of large-scale wind turbines (above 5MW), trying to seize the commanding height of the future wind turbine equipment industry competition. Sinovel and Goldwind, two leading domestic wind turbine industry leaders, plan to complete the research and development and prototype installation of 6MW wind turbines in the past two years. This move directly promotes the acceleration of domestic wind turbines' large-scale trend.

Li Shengmao, a senior research fellow at China Investment Consulting Co., Ltd., pointed out that the focus of the current domestic wind farm construction has gradually shifted from land to sea. This is the main reason why domestic wind turbine companies are increasingly optimistic about large wind turbines. At present, most of the regions with rich onshore wind resources in China have already built wind farms or have relatively clear construction plans, so the market demand for wind turbines of around 1.5 MW favored by onshore wind farms will slow down in the next few years. At the moment, the construction of domestic offshore wind farms is on the rise, and the natural conditions of offshore wind farms have determined that large-scale offshore wind farms are increasingly welcomed by project owners.

Li Shengmao believes that when domestic wind turbine manufacturing companies develop large-scale wind turbines, they must take into account the quality and specialization of fan products. The sea area suitable for the construction of offshore wind farms in the eastern coastal areas is very broad. With the increasing scale of domestic offshore wind farms, it is undeniable that wind turbine companies with first-mover advantage in the research and development of large-scale offshore wind turbines will have more opportunities in this process. Gain competitive advantage, but the premise is that the quality of the wind turbine can be guaranteed.

Zhang Yanlin, research director of China Investment Consulting Co., Ltd. pointed out that fan manufacturing is an advanced large-scale equipment manufacturing industry. For a wind turbine manufacturing enterprise to make breakthroughs in the large-scale wind turbines, one needs the improvement of its R&D strength and manufacturing process; on the other hand, it needs The key components and components of the upstream wind turbines are coordinated and supported, and the current domestic key components and spare parts enterprises of wind turbines are still unable to meet the needs of large-scale machines. This is precisely one of the major obstacles to the current large-scale domestic wind turbines. Before the large-scale domestic wind turbine key component industry has been achieved, the large-scale component procurement system of the wind turbine companies will inevitably be unstable, which is a big test for the quality of large-scale wind turbines.
