The terrain of the loess hills and gullies in northern Shaanxi is complex, making it difficult to construct wind power projects on mountain ridges. The wind turbine positions are scattered on high ground, with many steep slopes and strong gusts, making the transportation of large items and high-altitude lifting a challenge everywhere. The construction team adjusted the construction plan according to local conditions, solved various difficulties in geological, meteorological, transportation and installation one by one, and successfully completed the construction of all units, allowing clean wind power to be transmitted from the Loess Plateau to the outside.

Basic Overview of the Project

The Yan'an Ansai 100000 kW wind power project is a key project of Yan'an's 14th Five Year Plan for new energy, and also a supporting project for Shaanxi Power's entry into Anhui Province's ultra-high voltage. The project involves the installation of 16 6.25-megawatt wind turbines, along with the construction of a 110 kV booster station and transmission lines. The project delivers an average of 220 million kilowatt hours of clean electricity annually, saves 60000 tons of standard coal annually, reduces carbon dioxide emissions by 170000 tons, and simultaneously drives local employment and supporting industry development.

Facing the mountainous challenges head-on

The project is located in a loess hilly and gully area, with widespread distribution of collapsible loess, large drop in machine positions, and a narrow construction site. The construction party uses three-dimensional construction simulation to plan the lifting and transportation routes, establishes meteorological warnings for the changing weather in mountainous areas, and flexibly adjusts the construction pace. 90% of the on-site roads have steep slopes, and after slope reduction and curve transformation, all wind turbine components have been successfully transported.Keywords: Ansai wind power, Shaanxi power entering Anhui, new energy

Strictly control the installation quality

The wind turbine adopts a hybrid tower steel tower combination structure, with a tower height of up to 160 meters. The mountain airflow is prone to interfere with high-altitude operations. The construction team strictly controls the assembly process to ensure the accuracy of tower docking and structural stability. After the project is successfully connected to the grid, it will continue to output green electricity, taking into account both ecological and economic benefits as well as social benefits, providing support for the regional dual carbon landing.Editor/Li Xiaohua
