In recent years, with the rapid economic development, wind energy becomes more and more fierce competition in the market. Based on the basic concept of wind power generation, this article will analyze wind power generation in the significance and the role of sustainable development in our country. In the risk analysis, the first based on the analysis of wind power projects characteristics, the various stages of the wind power project risk factors identified by phasing of construction of wind power feasibility study and design phase, investment and financing stage, building construction phase and operations and maintenance phases of the four stages of risk into account, and then build a relatively complete risk assessment system. In this model, the evaluation is treated atter-element determination, and then it will select the appropriate classical field and section domain, by using AHP to 17 sub-indexes were four stages weight distribution, and finally a combination of elements and AHP model, got the project Risk level.
