Location: Cuomei, Tibet.

The Zhegu distributed wind power project in Cuomei, Tibet is a scientific research and demonstration project of ultra-high altitude wind power in China and the first distributed wind power project in the Tibet Autonomous Region. It is located in Zhegu Town, Cuomei County, Shannan City, Tibet on the northern slope of the Himalayas, adjacent to Yarlha Shampo Snow Mountain. The average altitude of the wind farm is between 4850 and 5500 meters. It is the wind farm project with the highest altitude in the world. A total of 5 Hopewind wind power converters are installed in this project. One of the installation sites has an altitude of 5060 meters, and the hub center altitude of the unit is 5150 meters. It is currently the wind turbine with the highest installation altitude in the world.

In view of the harsh plateau environment, Hopewind combines years of converter development and practical experience to carry out technological transformation and upgrading on the 2.5MW direct-drive converter that is maturely applied at an altitude of 4000 meters. Special designs and strict test and demonstration work are carried out in multiple aspects such as insulation design, device selection, overall machine heat dissipation, heating and dehumidification, and lightning protection to create a 5000-meter-altitude special converter (full-power ultra-high plateau water-cooled converter), breaking through the altitude limit and standing on the top of the plateau.
