The highest wind farm in my country - the second phase of the Cuomeizhe Ancient Wind Farm project is fully connected to the grid for power generation

News from this site on October 4. According to official news from China Three Gorges, on October 4, my country's highest wind power project - Tibet's Cuomeizhe Ancient Wind Farm, 15 wind turbines with a single unit capacity of more than 3 MW, was successfully completed. Grid-connected power generation , including batch use of 3.6 MW wind turbines with the largest single unit capacity currently put into production in ultra-high altitude areas in my country.

According to reports, the Tibet Cuomeizhe Ancient Wind Farm is located in Cuo, Shannan City, at the northern foot of the Himalayas. In Zhegu Town, Meixian County, wind turbines are installed between 5,000 and 5,200 meters above sea level, with a total installed capacity of 72.6 MW and a total of 25 wind turbines .

According to inquiries on this site, the 10 units of the first phase project have been connected to the grid at full capacity in December 2021, becoming the first ultra-high-altitude wind power development technology research and technology demonstration project in the Tibet Autonomous Region, and also the first Wind power projects integrated into Tibet's main power grid

On August 3 this year, the first batch of five wind turbines with a single unit capacity of 3.6 MW in the second phase of the project were successfully connected to the grid to generate electricity. After the second phase of the project is fully put into operation, the annual power generation capacity of the wind farm will exceed 200 million kilowatt hours, which can meet the annual electricity consumption of nearly 140,000 surrounding households.

According to our understanding, the current energy structure of the Tibet Autonomous Region is mainly dominated by hydropower and photovoltaic power generation. Hydropower generation accounts for 89.81% of the total power generation and solar power generation accounts for 7.73%. The characteristics of "plenty and night shortage". The maximum load of the Zangzhong power grid usually occurs in winter (the maximum load is in November and December)

The wind speed is strong in winter and spring in Cuomei County, Shannan City, and the wind energy resources are good. Cuomeizhe Ancient Wind Farm The maximum power generation is often in winter, and the peak power consumption period at night is also the time when wind farms generate the best power. It can complement hydropower to a certain extent, which is conducive to optimizing the power supply structure and alleviating the shortage of power supply in Tibet's power grid in winter. Case.

According to Wang Liang, the person in charge of the Three Gorges Group’s Cuomeizhegu Wind Power Project, based on the successful construction of the first phase of the project, the project team increased investment in technological innovation.

The second phase of the project all uses single-machine capacity of 3 megabytes For models with a capacity of 3.6 MW or above, the maximum single unit capacity reaches 3.6 MW, which can effectively improve the utilization efficiency of local wind resources. The diameter of the 3.6 MW wind turbine impeller is 160 meters, and the center of the wind turbine hub is 90 meters above the ground. It has technical features such as high altitude adaptability, UV protection, lightning protection, low temperature resistance, and ice resistance, and can be stable for a long time in harsh natural environments. run. China Three Gorges stated that the Cuomeizhegu wind power project has been successfully integrated into the power grid, laying the foundation for large-scale contiguous development of wind power in the future. This will help build multi-energy complementary bases in high-altitude areas and provide a new way for Shannan City to achieve rural revitalization and promote high-quality economic and social development. It is of great significance for the Tibet Autonomous Region to ensure energy supply and achieve the goal of "carbon peaking and carbon neutrality"
