Recently, the first air-cooling doubly-fed wind power generator with the largest power in China was launched at CRRC Yongji successfully! And on December 17, successfully passed the full-power drag test on the 4.XMW platform. Next, it will be sent to the Zhangbei testing wind field for grid-connected test.
It is understood that most of the doubly-fed wind power generators with power more than 3MW use air-water cooling technology. For wind turbines, the air-water cooling system has higher manufacturing costs and fault rates. At present, there is no air cooling technology for wind power generators with 4MW and above power levels. The air cooling wind power generator developed by CRRC Yongji is a brave innovation based on customers' needs. It adopts self-ventilation cooling technology and abandons The water-cooling equipment, has the advantages of high power, low noise, high efficiency and high reliability, which can meet the economic requirements of the 4.XMW platform wind power market in recent years.
CRRC Yongji has nearly 20 years of experience in wind power generator research and development. It has research and development experience in doubly-fed generators, permanent magnet direct drive generators, permanent magnet semi-direct drive generators, squirrel cage generators, etc. The product can be equipped in the complex operating environments like high altitude, low wind speed, frigid, high-temperature, sandy, coastal and offshore, and can meet the power grid demands of different voltages and low power factor. Up to now, more than 26,000 wind power generators of various types have been provided to customers around the world, and the products are distributed to more than 1,100 wind power fields worldwide.
