【Abstract】Huaneng Butuo Phase II (Buer) Wind Farm is an important project in the planning and construction of a tens of millions of installed wind power bases in Liangshan Prefecture. This project installs 25 wind turbines with a single unit capacity of 2.0 MW. The annual power generation is around 80 million KW.h. , through the transmission line to send clean energy to thousands of households. Due to the special geographical conditions, the location of the project caused many foggy days, low visibility, and complex terrain, which is extremely unfavorable for hoisting. The installation model is FD108C wind turbine, and the impeller rotation diameter is 108m, which is extremely difficult to install. During the construction process, the 9th Bureau of Hydropower went deep into technical research, strengthened management and control, optimized technical solutions, solved construction problems, ensured project schedule, quality, safety and control, improved the company's reputation, and achieved good economic benefits. In order to solve the specific construction problems, the cloth wind power hoisting as the background, in-depth analysis of construction visibility, safety, work efficiency and other aspects of construction difficulties under low visibility, difficult installation conditions, summarized the specific treatment measures for the construction difficulties of this project to ensure Construction safety, improve construction progress and save cost.

1. 引言
目前,國家風電建設正在向西部發(fā)展,包括西南、西北兩大風電基地目前正在逐步進行,其中西南風力條件好,滿發(fā)率高,但西南地區(qū)大多數(shù)為山地地區(qū),大霧天數(shù)多,對風機吊裝產生了極大的影響,因此應該從根源進行研究,有針對性的提出解決方案,并將方案進行總結、優(yōu)化,形成一整套的吊裝理論,保證后期在這種條件下可實現(xiàn)快速吊裝,為今后風電建設打下一個良好的基礎。
