Review and prospect of key technologies for anti/de-icing technologies of wind turbine blades

Ice accumulation on wind turbine blades can lead to power loss, affecting the safety of the units and the stability of the power grid. Through ice accumulation prediction on blades and ice prevention and removal measures, the impact of icy climatic environments on wind turbines can be reduced, which helps ensure the safe and stable operation of wind turbines. This paper reviews the key issues, research status, and development trends of icing prediction and anti/de-icing technologies for wind turbine blades, expounds on the mechanism and hazards of ice formation, summarizes the mechanism model method and data-driven method for ice accumulation prediction, analyzes the characteristics of passive ice prevention and removal technologies, active ice removal technologies, and collaborative ice prevention and removal technologies, and compares the advantages, disadvantages, and risks of various technologies. It provides an important reference for the further development of ice prevention and removal technologies for wind turbine blades.
