China's largest wind turbine manufacturer Huarui Wind Power announced recently that the project of the National Science and Technology Ministry's 863 Program “Key Technology Development and Complete Machine Development for 1.5MW Low Wind Speed ​​Wind Turbines†was recently reviewed and approved by the expert group of the Ministry of Science and Technology. The indicators and cost advantages of the low-speed wind turbines were all highly evaluated by experts from the Ministry of Science and Technology.
According to Bai Jianhua, director of the National Grid Energy Strategy and Planning Institute, the country’s policy support for the development of low wind speed wind power is increasingly clear. In the next five years, China will usher in a peak period of low wind speed development. The low wind speed wind turbine developed by this project has a broad market prospect.
According to statistics, the area of ​​low wind speed resources available nationwide accounts for about 68% of the national wind energy resources, and both are close to the receiving end of the grid load. However, at present, wind power development in China is concentrated in high wind speed areas with abundant wind resources such as the Three North (northwest, northeast, and north China) and southeast coast. Wind power development in the low wind speed area is almost blank. In June 2009, Sinovel started the research and development of wind turbines with low wind speed suitable for IEC III wind zones below (average wind speed between 5 and 7m/s), and has been listed in the Advanced Energy Technology field of the National Science and Technology Ministry's 863 Program. Part of the topic of renewable energy technologies.
In the acceptance of this project, members of the expert group from the Ministry of Science and Technology unanimously held that the SL1500/82 and SL1500/89 wind speed wind turbines independently developed by Sinovel have completed the tasks and assessment objectives specified in the project task book. Main Specifications. The cut-in wind speeds of these two low-speed wind turbines can reach below 2.8m/s, and the rated wind speeds are 10.5m/s and 10m/s, respectively. It has the advantages of low cut-in wind speed, large power generation in low wind speed area, etc. At the same time, it greatly reduces the unit's weight and manufacturing cost.
According to the research team leader Han Junliang, chairman and president of Sinovel Wind Power, according to China's wind power development plan, during the 12th Five-Year Plan period, wind power will change from the original construction of large bases and integration into large-scale power grids to a centralized and decentralized development model, and shift to the development of low wind speed winds. Field and encourage the decentralized access to the grid. This means that the development of wind resources in low wind speed areas has become one of the important strategic layouts of the national wind power plan for the Twelfth Five-Year Plan, and Huarui Wind Power is a long-term development strategy based on technological innovation, localization, scale, large-scale, and internationalization. We will continue to increase R&D investment, improve the company's scientific and technological R&D capabilities, and strive to build the most competitive wind power equipment companies in the world, achieving the strategic goal of challenging the world's No. 1 within five years.
Abrasive Cloth is the cloth with grinding compound. According to the different grinding compound, the abrasive cloth can divided into four kinds: Aluminum Oxide Abrasive Cloth, Silicon Carbide Abrasive Cloth, Zirconium Oxide Abrasive Cloth and Calcined Aluminum Oxide Abrasive Cloth and so on. According to the hardness, it also can be divided into flexible abrasive cloth,middle flexible abrasive cloth and hard abrasive cloth. Some of them can do waterproof or oil-proof. The shape of the abrasive cloth is roll, belt and sheet. The abrasive cloth is generally used for wood grinding and metal grinding. It can available in vary grits.
After 30 years` development, abrasive cloth grinding has become a complete and self-contained system of new processing technology. Because of its high processing efficiency, wide application range, strong adaptability, low cost, safe and convenient operation, it is well received by customers. In foreign countries, Abrasive Belt grinding technology has made great progress. It can be applianced for more and more processing object . It can process almost all engineering materials, from the general daily life appliance to application of large aerospace equipment.
