Lightning disaster seriously threatens the stable operation of wind turbines. However, there is still a lack of research on the influence of high-speed airflow on wind turbines’ corona charge distribution and lightning shielding characteristics. Therefore, this paper quantitatively analyzes the influence of high-speed airflow on the space charge and potential of the wind turbine blade tip. Furthermore, a calculation model of wind turbine lightning shielding considering the influence of corona charge under high-speed airflow is established to analyze the influence of high-speed airflow on lightning striking distance and shielding efficiency. The results show that the corona charge will migrate toward the lightning cloud and airflow direction under the electric field and high-speed airflow combined. At the same time, high-speed airflow will lead to an increase in lightning strike distance. With the increased airflow velocity, the shielding efficiency of the lightning arrester on wind turbine tip is improved. As the size of the wind turbine becomes larger, the shielding effect of the blade tip lightning arrester is weakened, and the high-speed airflow improves the shielding efficiency of the arrester more significantly.
