The wind power resources are extremely rich in engineering site area, which has very good wind resources development prospects. Firstly, according to the wind farm area economy development and power grid development situation, this paper analyzes the relationship between projects and grid system, and the development scale of the project and the current development capacity. Secondly, wind energy resources of project area are evaluated by using the wind tower complement and meteorological data. Based on the analysis, the local wind energy resources are rich. Then, the local resource conditions are analyzed in detail, and determine the optimal wind turbines and optimal flight arrangement through schemes comparison. After considering the various reductions, the annual energy outputs of wind farms are calculated. Finally, Based on the analysis of the payback period of investment, financial net present value, and the internal rate of return and other indicators, it is found that this project has good liquidity and profitability. This paper carefully analyzes the economic benefit and social benefit of the project. The wind power in the project location is relatively abundant, and the project has good feasibility.
