Lightning damages of the wind turbine blades are always a problem for the wind power system

and the lightning protection of the blades is top priority of investigation. We systematically summarized the researches on the lightning protection of the wind turbine blades in China and aboard

including the lightning observation of the wind turbine blades

the simulation experiment on the lightning damages

the mathematical simulation of the lightning strike

and the optimal design of the lightning protection system（LPS）. In view of the existing research deficiencies

we proposed that in-depth research should be carried out in the future in the following five aspects: The multiple physical parameter observation system of the wind farms must be studied

and the continuous observation of wind farms located at plane

mountains and oceans should be set up. The equivalence of the spatiotemporal distribution of the electric field should be improved

in order to study the process of the upward discharge from the wind turbine blade. The influence of the electric field caused by space charge should be taken into account in the future leader progressing model

and the leader progressing model for the upward lightning of the wind turbine blades should be established. The optimal design of the lightning protection system and the mechanism of the lightning damage of the wind turbine blades should be conjointly analyzed

and theinfluence of the mechanical property after optimizing should be considered. The systematic research on the lightning protection of the Carbon Fiber Reinforced Plastics（CFRP） wind turbine blades should be carried out as soon as possible.
