Abstract：Extensive researches on anti-icing and de-icing technologies have been greatly developed in order to solve the aerodynamic performance deterioration, power generation loss and blade fracture, as well as other technical problems caused by wind turbine blade icing. The icing mechanism, types and influencing factors of wind turbine blades were summaried; for which the methods and techniques of wind turbine blade icing fault diagnosis were analyzed based on operating parameters and historical monitoring data. It also summarizes domestic and foreign wind turbine icing failure prediction technologies in recent years as well as existing problems and research hot spots in this field from three aspects: blade aerodynamic characteristics, mathematical model methods and intelligent data mining. The anti-icing and de-icing methods and technologies of wind turbine blades and their respective advantages and disadvantages were focused on, the existing anti-icing and de-icing methods and application status and existing problems and development trends were discussed. The key issues that may be involved in the development and utilization of diagnosis and prediction technology, efficient anti-icing technology, etc. are summarized, with a view to providing reference and guidance for the development of anti-icing technology for wind farms in cold and humid areas.
