摘要：

To provide a theoretical basis for the lightning protection of gravity basic offshore wind turbines， an integrated electromagnetic transient model is constructed. Based on the electromagnetic transient software ATP- EMTP，the lightning transient response is studied，and the influence of key factors such as blade length，tower height and blade rotation angle are analyzed. The simulation results show that the transient voltage of MV level is caused by lightning strike，and it exhibits underdamped oscillation attenuation，and the response voltage of kV level still exists at the gravity foundation. Both blade length and wind turbine tower height are positively correlated with lightning transient response amplitude. The transient voltage in the cabin is highest when the angle between the lightning-struck blade and the horizontal plane is 90°. © 2023 Science Press. All rights reserved.
