On November 9th, China North Locomotive Group's Yongji Motor Factory successfully developed the country's first 1.5 MW water-cooled doubly-fed wind turbine with independent intellectual property rights. This milestone marks a significant advancement in China's wind power industry, as it now has the capability to produce international-standard double-fed generators. The development reflects the growing maturity and innovation of China's renewable energy sector.
The first batch of two 1.5 MW wind turbines was designed and manufactured by Yongji Motor for a leading domestic wind turbine manufacturer. Wind energy, known for being clean, pollution-free, and fuel-independent, has become a key player in global renewable energy strategies. With an annual growth rate of 37.4%, China's wind power market is expanding rapidly, offering vast opportunities for future development.
Yongji Motor, a major Chinese enterprise specializing in electric drive systems for locomotives, has leveraged its 30 years of expertise in motor design and manufacturing to enter the wind power industry. Since 2001, the company has been actively involved in wind turbine production. It previously developed China's first dual-winding, two-speed asynchronous wind turbines of 660 kW and 750 kW, both with independent intellectual property. These models quickly became the most popular locally produced wind turbines, with Yongji's wind power products capturing over 80% of the domestic market.
In February of this year, Yongji Electric signed a contract with a major domestic wind turbine manufacturer to produce a 1.5 MW water-cooled doubly-fed wind turbine. This project marked the company's first independently designed and developed megawatt-class wind turbine. Unlike previous models, this new design features improved heat dissipation, reduced noise, and higher material efficiency. The turbine is well-suited for varying wind conditions across different regions in China and plays a crucial role in reactive power regulation, significantly enhancing the utilization of wind energy.
Currently, Yongji Electric has established a dedicated research institute focused on wind power technology, including motor design and frequency conversion controllers. A 2.0 MW wind turbine testing station is also under construction. The company plans to expand its R&D efforts to develop a wide range of wind generators and control systems, aiming to achieve mass production and eventually enter the global wind power market.
