Driving on the roads in Inner Mongolia, the blades of "big windmills" can be seen dancing everywhere, and the transmission lines are connected to all directions... Wind power is becoming a beautiful landscape for the development of Inner Mongolia's new energy industry.

Inner Mongolia Autonomous Region is an important energy base in my country. Last year, the number of new energy installed capacity in the local area exceeded 41 million kilowatts, an increase of more than 30% year-on-year. The total installed capacity of new energy reached 135 million kilowatts, of which the installed capacity of wind power exceeded 85 million kilowatts.

The booming development of the new energy industry cannot be separated from the leadership of leading enterprises. Walking into the intelligent industrial base of Yunda Co., Ltd. in Ulanqab, the production and manufacturing site is in full swing. Workers work overtime to assemble the 10-megawatt wind turbine, and after the product is completed, it will be sent to a large wind power base in the autonomous region.

"Our base has the first 13-megawatt-level onshore wind turbine full-power test platform in the country, and plays an important role in the innovation and development of enterprises. At the same time, the base has an annual wind power equipment production capacity of 5 million kilowatts, and its main products are 4-megawatt-10-megawatts and above wind turbines, mainly meeting the needs of Inner Mongolia and surrounding areas." Zhao Huaxing, deputy general manager of Inner Mongolia Yunda Energy Co., Ltd., introduced that as an important modern energy equipment manufacturing project introduced under the "energy + industry" development model of Ulanqab, the company will play the role of "chain leader", continue to drive the development and introduction of local and upstream and downstream supporting industries, and promote the quality and quality of the new energy equipment manufacturing industry.

At the Ulanqab blade base of Vision Technology Group not far away, the newly built carbon fiber blade mold in the factory attracted the attention of reporters.

"Carbon fiber blades have strong toughness and light weight, and have broad market prospects. Our newly launched carbon fiber blade mold has completed the commissioning work and is expected to start production after the year, which will bring new growth points to the company." Nie Jianjun, the head of the base, told reporters that carbon beam wind power blade products with carbon fiber composite materials were prepared through pultrusion molding. They have high strength, corrosion resistance, fatigue resistance, creep resistance and other characteristics, and are more in line with the development trend of large-scale and lightweight wind power blades. At present, the factory has the production and manufacturing capabilities of carbon fiber blades, which will significantly enhance the competitiveness of the company.

The seemingly ordinary blades have a low technological content. "CFD simulation (fluid dynamics) technology is used during the design process to predict the performance of blades in complex airflows and make necessary adjustments. By calculating CFD simulation and optimization algorithms, more efficient blade shapes are designed to reduce air resistance and improve wind speed utilization." Nie Jianjun said that high-precision manufacturing processes are crucial to ensuring the geometric shape and aerodynamic performance of blades. The factory has introduced a variety of automated and intelligent manufacturing technologies to ensure blade quality and performance.

Walking into the assembly plant of Mingyang New Energy Intelligent Manufacturing Industrial Park located in Shiguai District, Baotou City, Han Jifei, the production section chief, was working with workers to work on the fan transmission chain to the shaft, inspect and adjust the parts...

"The transmission chain is the core component. The main shaft transmits the wind energy generated by the wind wheel to the transmission system, increases the speed through the gearbox, and converts it into electrical energy through the generator. The gearbox is the highest price of a single component in the entire set of fan equipment, and is also one of the core components." Han Jifei said that due to the tight time required for orders, more than 100 workers in the assembly plant are speeding up production to ensure the timely delivery of the products.

In the national blade test, testing and certification center outside the assembly plant, the blade roots of the super-large blades are fixed to the test bench through flanges, and swing horizontally and up and downward directions under the protection of the fixture. "This is a swing fatigue test of the blades, and the test cycle lasts for several months." Du Yunfei, head of the process equipment department of the Baotou Base of Mingyang Northern Smart Energy Inner Mongolia Co., Ltd., told reporters that the completion and operation of the center has improved the back-end links of the industrial chain, providing strong support for product quality control and technical research and development.

"The new energy industry has flourished in recent years, and the market orders are in good condition." Du Yunfei said that the company will actively promote the construction of a comprehensive empirical base project of wind power equipment through Mingyang Northern Research Institute and the Academician Workstation, and strive to improve the technical collaborative innovation and R&D level of wind power equipment, components and materials, test, testing, certification and evaluation capabilities, and market core competitiveness.

Inner Mongolia's new energy equipment industry is riding the wind and has formed an industrial chain covering upstream raw materials, midstream parts, downstream whole machines, as well as R&D design, experimental verification, wind farm operation and maintenance, over-limited parts transportation services, blade recycling and utilization, etc. The assembly capacity of the whole machine can meet the development needs of the region and surrounding markets.

Along with dancing leaves, the wind on the grassland is continuously transformed into green electricity, connected to the power grid like a tide and sent to thousands of households.
