The annual power generation capacity is 1.75 billion kilowatt hours.
Recently, the Tongyu 500,000-kilowatt wind power project, the first batch of supporting external wind power base projects invested and constructed by Shuifa Group, was connected to the grid at full capacity and put into trial operation. The project will construct 116 wind turbine units with an annual power generation of 1.75 billion kilowatt hours, which can save 485,000 tons of standard coal and reduce 1.261 million tons of carbon dioxide emissions.
Faced with difficult natural conditions, the owner of the wind power project, Huaneng Group, made many attempts. In the early stages of wind farm construction, the project initially planned to use crawler cranes for wind turbine hoisting. The technology is mature, widely used and stable, and is widely used in wind farm lifting. However, the lifting height of wind turbines in wind farms is as high as 130 meters, which also means that the crane requires more than 160 meters of space. The terrain conditions of most wind farms cannot meet this requirement.
With the cooperation between Huaneng and Envision, the aerial assembly hoisting method was finally adoptedA total of more than 10 parts of the 140-meter-long boom of the crane were moved to 20-30 meters above the ground. position and suspended for assembly, so that hoisting can be achieved and the project area can be reduced as much as possible. It is understood that such a large-scale use of aerial work robotic arm lifting solutions is still the first in the domestic mountainous lifting industry. Not only that, because the topography of each wind turbine location in the area is different, the long-term project staff also developed a separate and strict implementation plan for the hoisting of each wind turbine, ultimately achieving the hoisting of more than 70 overhead cranes.
The "one machine, one box" method was used on site to solve the difficultyThe hoisting construction of China's largest mountainous tower wind turbine set a record When the hoisting plan was first studied, a It took more than half a month to hoist the wind turbine, which took the longest time. As the construction plan continued to improve, the final construction phase was the fastest to strictly ensure safety and maintain the forest ecology. The wind turbine hoisting only took 5 days. Completed, normal hoisting time was shortened to 7 days, and hoisting costs in mountainous areas were greatly reduced.
Judging from the current development situation, considering the complex geographical conditions and arduous construction process, the development of wind power, from the perspective of the owners themselves, in order to reduce costs when wind energy resources are limited, , it may be necessary to choose larger capacity models and use taller towers, more efforts have been made in the form of tubes and longer blades, while hoisting prices are too high due to this year's "peak installation period" High, the future development of wind power in mountainous areas should also avoid peak periods to reduce construction and other costsThis will also help to achieve an increase in wind power prices as soon as possible in low wind speed areas. Accelerate the development of mountainous areas, such as the old revolutionary base area in Yan'an, Shaanxi.
