Abstract: Renewable energy based on wind energy is regarded as the most promising energy source of all energy sources available today. It has become an essential part of the new power supply. Wind turbine blades are crucial and relevant to the operating efficiency and service life of turbines. However, the working conditions of wind turbines are poor, and they are usually located in high or low temperatures, acid-base corrosion, and sandstorm environments. The blade's leading edge is highly prone to erode due to its high linear velocity. Here are summarized the factors affecting the leading-edge protection of wind turbine blades, and the protection scheme of the leading edge protection, and is put forward the problems existing in the development of the protection for the leading edge of the wind turbine blade protection.
