There are different degrees of deviation in the basic data acquisition, processing, management, analysis, mining and other aspects of wind tower in large new energy company. Therefore, this paper proposes the full life cycle management for wind tower, fully analyzes the rationality of site selection of wind tower and the importance of wind test technology in generating capacity improvement of wind farm, data analysis and secondary planning. Through the overall control of the wind tower data cycle in wind farm, we analyze the large amount of basic wind data in each stage such as pre-test wind survey, production data, post-production evaluation basis, in order to control the design deviation of wind power project from source. Through the discussion of wind tower data collection feasibility in wind farm, we strengthen the accurate evaluation of the project, to provide reliable data support for the promotion of benefit. Taking the full life cycle data of wind tower in wind farm as a measure basis of capacity, we adopt a large number of real-time data technology as the basis data for fault warning, equipment diagnosis, operation optimization and standardization promotion, and implement the closed-loop management for wind data, which can provide accurate data support for all aspects of design and construction of wind farms.
