Abstract: Aiming at the problems of single working form, short working time and low efficiency of technology supervision in Inner Mongolia, the application management system for wind farm technology supervision is designed by Inner Mongolia Power Research Institute. It includes data access layer, logic profession layer, and functional presentation layer. Its functional modules include statistical analysis module, training exchange module, technical supervision module, etc. Through the system, problems existing in technology supervision can be solved. It realizes the standard division and management of all the professional technical supervision work, and standardizes the technical supervision test project, test plan and approval management process. The technical training platform is established. It can effectively improve the efficiency of technology supervision, and guide wind power enterprises to establish and improve the technology supervision system and technical files of major equipments, and provide technical support for technology supervision of wind farms.
