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 achievement marks a significant milestone in China's wind power industry, as it now has the capability to develop and produce advanced, internationally recognized double-fed generator systems.
It is reported that the first batch of two 1.5 MW wind turbines was designed and manufactured by Yongji Motor for a leading domestic wind power main engine manufacturer. With its clean, pollution-free energy generation and no fuel consumption, wind power has become one of the most promising renewable energy sources globally. China's wind power sector is growing rapidly, with an annual growth rate of 37.4%, indicating a bright future for the market.
Yongji Motor, a major Chinese enterprise specializing in electric drive equipment for locomotives, has been leveraging its 30 years of experience in motor design and manufacturing. The company entered the wind turbine market in 2001, seizing the opportunity of China's wind power industrialization. It previously developed China's first dual-winding, two-speed asynchronous wind turbines of 660 kW and 750 kW, with independent intellectual property rights. The 750 kW model quickly became the largest locally produced wind turbine in China, and wind power products from Yongji Motor accounted for over 80% of the domestic market.
In February of this year, Yongji Electric signed a production contract with a domestic wind power main engine factory for the 1.5 MW water-cooled doubly-fed wind turbine. This project marked the successful development of China's first megawatt-level water-cooled doubly-fed wind turbine. Unlike previous models such as the 750 kW and 660 kW turbines, this new design offers better heat dissipation, lower noise levels, and higher material efficiency. It can adapt to various wind conditions across different wind farms in China and plays a crucial role in grid reactive power regulation, significantly improving the utilization of wind energy.
Currently, Yongji Electric has established a wind power plant technology research institute focused on motor design and frequency conversion controllers. A 2.0 MW wind turbine test station is also under construction. The company is intensifying its 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.
