Abstract: Wind turbines are prone to blade icing while in low temperature and humid environments, which seriously affects the safety and reliability of wind turbines seriously, and also affects power generation efficiency. This thesis is based on aircraft anti-icing coatings and low adhesion coatings technologies, elaborated from the detection and monitoring technology of blade icing, then focused on active deicing technologies such as liquid flow deicing, mechanical deicing, electric heating deicing and air-heating deicing. Through analyzed and compared different deicing technologies, it is concluded that electric heating deicing and air-heating deicing will be the main direction of research and application. Finally, it is recommended to considering the blade icing reduction ratio as affecting investment factor when in a new projects, and considering installing deicing systems when purchase wind turbines for the new project which blade icing reduction.
